Alternatively, there is a process for ending the game when the game end condition is satisfied.

  In this embodiment, the player characters of a plurality of (for example, four players) play a battle royal style battle game, and the upper (for example, two) player characters have won, and the remaining player characters proceed to the next battle. be able to.

  Each player character's physical strength value is set to an initial value (for example, 100) at the start of the game, and each player is set for each frame during a game period (for example, 90 seconds) from the start of the game to the end of the game. The hit determination process is performed based on the input information from and the physical strength value of each player character is subtracted based on the hit determination result. When the physical strength value of each player character becomes 0, the defeat of the player character may be confirmed. Also, when the number of player characters whose physical strength value is greater than 0 is greater than the remaining number of players when the game period has elapsed, it is determined that the player character with the higher physical strength value will remain in the higher ranking.

  The game calculation unit 110 functions as a battle calculation unit that performs a battle calculation of a plurality of character objects existing in a virtual three-dimensional space based on game information including input information for a plurality of game machines.

  The object space setting unit 111 is a primitive such as a character object, a moving object, a building, a stadium, a car, a tree, a pillar, a wall, a map (terrain), or other objects (polygon, free-form surface, subdivision surface, or the like). The object is configured to be placed in the object space. In other words, the position and rotation angle of the object in the world coordinate system (synonymous with direction and direction) are determined, and the rotation angle (rotation angle around the X, Y, and Z axes) is determined at that position (X, Y, Z). Arrange objects.

  The virtual camera control unit 112 performs a virtual camera control process for generating an image that can be viewed from a given (arbitrary) virtual camera (viewpoint) in the object space. Specifically, processing for controlling the position (X, Y, Z) or rotation angle (rotation angle about the X, Y, Z axis) of the virtual camera (processing for controlling the viewpoint position, the line-of-sight direction or the angle of view) I do. Further, the angle of view may be controlled.

  For example, when an object (for example, a player character, a ball, or a car) is photographed from behind using a virtual camera, the virtual camera position or rotation angle (virtual) is set so that the virtual camera follows changes in the position or rotation of the object. Control camera orientation). In this case, the virtual camera can be controlled based on information such as the position, rotation angle, or speed of the object obtained by the movement / motion processing unit. Alternatively, the virtual camera may be controlled to rotate at a predetermined rotation angle or to move along a predetermined movement path. In this case, the virtual camera is controlled based on the virtual camera data for specifying the position (movement path) or rotation angle of the virtual camera. When there are a plurality of virtual cameras (viewpoints), the above control process is performed for each virtual camera.

  In addition, when the given character object executes a predetermined command on the action target character object, the virtual camera control unit 112 performs the given character object, the action target character object, and the secondary action target. The placement of the virtual camera may be controlled based on the position of the character object.

  The movement / motion processing unit 113 performs a movement / motion calculation (movement / motion simulation) of a model (character, car, train, airplane, etc.). That is, the model is moved in the object space or the object is moved (motion, animation) based on operation data input by the player through the operation unit 160, a program (movement / motion algorithm), various data (motion data), or the like. ) Process. Specifically, object movement information (position, rotation angle, speed, or acceleration) and motion information (position or rotation angle of each part that constitutes the object) are sequentially transmitted every frame (1/60 seconds). Perform the required simulation process. A frame is a unit of time for performing object movement / motion processing (simulation processing) and image generation processing.

  In particular, the movement / motion processing unit 113 of the present embodiment can perform processing for moving / moving the player character to be operated by the player based on input information from the player. Further, based on the game data of the other machine included in the packet transmitted by the communication control unit 115 described later, the second character object to be operated by the player using the other machine is changed to the operation of the player using the own machine. It is possible to perform a process of moving and moving in the same object space as the target first character object.

  The movement / motion processing unit 113 according to the present embodiment, based on the game data input from the operation unit of the player's own device, performs a calculation for operating the first character object to be operated by the player using the player's own device, and a network. On the basis of the game data received from the other device, the player can operate the player character (second player character or third player character) to be operated using the other device.

  The movement / motion processing unit 113 also functions as a command processing unit that performs a movement motion calculation of the character object by a predetermined command.

  In addition, the movement / motion processing unit 113 performs a motion of a given character object based on the target position when the given character object performs an action defined by a predetermined command on the character object to be acted on. It functions as a motion correction processing unit that performs correction.

  The network setting unit 114 performs processing for acquiring and managing network information necessary for the game system. In particular, the network setting unit of the present embodiment includes game machine identification information (data individually assigned to identify game machines that can participate in an online game) assigned to each game machine, A process for acquiring and managing destination information that specifies a transmission destination of a packet associated with the identification information is performed.

  Further, the destination information can be the IP address and port number of each game machine constituting the game system. The IP address may be a global IP address for specifying a specific game machine on the Internet or WAN, or may be a private IP address for specifying a specific game machine on the LAN.

  The communication control unit 115 generates a packet to be transmitted to other machines (second game machine to fourth game machine), processes to specify the IP address and port number of the game machine to which the packet is transmitted, and the received packet A process of saving data included in the storage unit 170, a process of analyzing a received packet, a control process related to transmission / reception of other packets, and the like are performed.

  A packet is a cluster that communicates via a network, and refers to data composed of a header including a transmission source IP address and a transmission destination IP address, and data written at the transmission source as a payload.

  Further, in order to realize application-level communication, a packet is generated by designating a port number that identifies the type of application corresponding to the TCP or UDP protocol to be used. For example, the TCP protocol has high data transmission / reception reliability, and uses, for example, an acknowledgment or retransmission. Further, the TCP protocol can perform retransmission processing of lost data, and can further secure a data transmission order and transmit a packet to a destination game machine. On the other hand, in the UDP protocol, even if data is lost in the middle of transmission, it may not be retransmitted and may be transmitted in a reversed order. However, since the UDP protocol has no overhead compared to the TCP protocol, it may be suitable for an online game that transmits data in real time. When using the UDP protocol, the game data to be input to the buffer is input in the order of identification numbers (ascending order). If the game data of the identification numbers to be input has not arrived, a request is made to another machine. It may be. In this embodiment, any protocol can be supported. If the UDP protocol is used, the input order of game data to the buffer may be controlled to be input in ascending order of identification information (identification number).

  The communication control unit 115 according to the present embodiment performs processing for generating a packet according to a frame rate for drawing an image and transmitting the generated packet to a plurality of other connected game machines. More specifically, for example, when the frame rate is 60 fps, the IP address of the second game machine is used for the transmission destination IP address and transmission destination port number of the packet header every 1/60 seconds. Specify the port number to be used, specify the IP address and source port number of the header in the header, specify the IP address of the other game machines and the port number to be used, and enter the data including game data into the packet payload And the process which transmits the produced | generated packet to several other game machines is performed.

  Here, the game data is data including input information (including operation information) from a player who operates the game machine for each frame. For example, the game data can be data indicating the presence or absence of input information, or the content of the input information when there is input information. For example, when the game data is indicated by a numerical value, the game data is set to “0” when there is no input information, and the game data is set to “1” when there is input information and the content is input from the A button. If there is input information and the content is input from the B button, the game data is set to “2”. In addition, if there is input information and the content is input of the A and B buttons, the game data is set to “3”.

  Here, the identification information is data common to a plurality of game machines (first and second game machines) given for each frame. In the present embodiment, the information given to each frame according to the elapsed time can be used with reference to the time when the connection between the first game machine and the second game machine is established. For example, in a game machine, a sequential identification number (a positive integer starting from 1) associated with game data acquired according to the frame rate can be used.

  For example, considering a case where the frame rate is 60 fps, identification information is associated with game data acquired every 1/60. For example, in each of the first game machine and the second game machine, the game data acquired when the connection is established is associated with the identification number “1” and acquired 1/60 seconds after the connection is established. An identification number “2” is associated with the game data, and an identification number “3” is associated with the game data acquired 2/60 seconds after the connection is established.

  In addition, the communication control unit 115 of the present embodiment performs processing for receiving packets transmitted from other game machines. Then, the received packet is analyzed, and data including game data included in the payload of the packet is acquired. The received game data is input to the second buffer 178 in the buffer control unit 116 described later.

  In addition, the communication control unit 115 of the present embodiment stores game data until a connection is disconnected after a connection (connection between the first game machine to the fourth game machine) is established between a plurality of game machines. Can be transmitted / received to / from each other.

  In addition, one game machine can be specified as a parent machine among a plurality of game machines belonging to a communication group participating in the game of the present embodiment. The parent machine may be a game machine that generates a game space.

  When executing a predetermined command input to a given character object, the command processing unit 122 gives a character object other than the given character object and the character object that is the action target of the given character object. As a secondary action target of the character object, a target position is determined based on the position of the character object that is the secondary action target, and the action target character object is moved to the target position.

  In addition, the command processing unit 122 performs the action of the given character object and the given character object based on input information from a game machine in which the given character object is set as a player character. A process for determining a character object to be a target of the secondary action may be performed.

  The action target setting unit 124 sets a character object as an action target of the given character object based on action target input information input to a game machine in which the given character object is set as a player character. The command processing unit 122 is set as the action target of the given character object when the predetermined command or another command is input from a game machine in which the given character object is set as a player character. The predetermined command or another command is executed with the target character object as a target, and the action target setting unit 124 becomes the action target of the given character object when the predetermined command is executed. A process of changing the action target of a character object to the character object that is the secondary action target of the given character object may be performed.

  Further, when executing the predetermined command, the command processing unit 122 calculates a movement path of the action target character object based on the position of the action target character object and the target position, and an obstacle on the movement path. Processing for determining whether or not there is an object may be performed.

  If the command processing unit 122 determines that there is an object serving as an obstacle, the command processing unit 122 may perform a movement route change process for changing the movement route.

  When the command processing unit 122 determines that there is an obstacle object on the moving route, and the obstacle object has an attribute that can be destroyed or disappeared, The action target character object may be moved along the moving path, and the object that becomes the obstacle may be destroyed or disappeared.

  The enemy notification image display control unit 126, when a given character object is an action target of another character object, notifies the other character object whose action target is the given character object. Perform image display control.

  Further, the enemy notification image display control unit 126 may perform display control of a line image including a line connecting the character object and the action target character object as the enemy notification image.

  The drawing unit 130 performs drawing processing based on the results of various processing (game processing) performed by the processing unit 100, thereby generating an image and outputting the image to the display unit 190. When generating a so-called three-dimensional game image, first, object data (model data) including vertex data (vertex position coordinates, texture coordinates, color data, normal vector, α value, etc.) of each vertex of the object (model) ), And vertex processing (shading by a vertex shader) is performed based on vertex data included in the input object data (model data). When performing the vertex processing, vertex generation processing (tessellation, curved surface division, polygon division) for re-dividing the polygon may be performed as necessary. In the vertex processing, according to the vertex processing program (vertex shader program, first shader program), vertex movement processing, coordinate conversion (world coordinate conversion, camera coordinate conversion), clipping processing, perspective processing, and other geometric processing are performed. On the basis of the processing result, the vertex data given to the vertex group constituting the object is changed (updated or adjusted). Then, rasterization (scan conversion) is performed based on the vertex data after the vertex processing, and the surface of the polygon (primitive) is associated with the pixel. Subsequent to rasterization, pixel processing (shading or fragment processing by a pixel shader) for drawing pixels (fragments forming a display screen) constituting an image is performed. In pixel processing, according to a pixel processing program (pixel shader program, second shader program), various processes such as texture reading (texture mapping), color data setting / change, translucent composition, anti-aliasing, etc. are performed, and an image is processed. The final drawing color of the constituent pixels is determined, and the drawing color of the perspective-transformed object is output (drawn) to the image buffer 174 (buffer that can store image information in units of pixels; VRAM, rendering target). That is, in pixel processing, per-pixel processing for setting or changing image information (color, normal, luminance, α value, etc.) in units of pixels is performed. Thereby, an image that can be seen from the virtual camera (given viewpoint) in the object space is generated. Note that when there are a plurality of virtual cameras (viewpoints), an image can be generated so that an image seen from each virtual camera can be displayed as a divided image on one screen.

Note that the vertex processing and pixel processing are realized by hardware that enables polygon (primitive) drawing processing to be programmed by a shader program written in a shading language, so-called programmable shaders (vertex shaders and pixel shaders). Programmable shaders can be programmed with vertex-level processing and pixel-level processing, so that the degree of freedom of drawing processing is high, and expressive power is greatly improved compared to conventional hardware-based fixed drawing processing. Can do.

  The drawing unit 130 performs geometry processing, texture mapping, hidden surface removal processing, α blending, and the like when drawing an object.

  In the geometry processing, processing such as coordinate conversion, clipping processing, perspective projection conversion, or light source calculation is performed on the object. Then, object data (positional coordinates of object vertices, texture coordinates, color data (luminance data), normal vector, α value, etc.) after geometry processing (after perspective projection conversion) is stored in the object data storage unit 176. Is done.

  Texture mapping is a process for mapping a texture (texel value) stored in the texture storage unit of the storage unit 170 to an object. Specifically, the texture (surface properties such as color (RGB) and α value) is read from the texture storage unit of the storage unit 170 using the texture coordinates set (given) to the vertex of the object. Then, a texture that is a two-dimensional image is mapped to an object. In this case, processing for associating pixels with texels, bilinear interpolation or the like is performed as texel interpolation.

  As the hidden surface removal processing, hidden surface removal processing can be performed by a Z buffer method (depth comparison method, Z test) using a Z buffer (depth buffer) to which a Z value (depth information) of a drawing pixel is input. . That is, when a drawing pixel corresponding to the primitive of the object is drawn, the Z value input to the Z buffer is referred to. Then, the Z value of the referenced Z buffer is compared with the Z value at the drawing pixel of the primitive, and the Z value at the drawing pixel is a Z value (for example, a small Z value) on the near side when viewed from the virtual camera. In some cases, the drawing process of the drawing pixel is performed and the Z value of the Z buffer is updated to a new Z value.

  α blending (α synthesis) is a translucent synthesis process (usually α blending, addition α blending, subtraction α blending, or the like) based on an α value (A value).

  The α value is information that can be stored in association with each pixel (texel, dot), for example, plus alpha information other than color information. The α value can be output as mask information, translucency (equivalent to transparency and opacity), bump information, and the like.

  The sound generation unit 140 performs sound processing based on the results of various processes performed by the processing unit 100, generates game sounds such as BGM, sound effects, or sounds, and outputs the game sounds to the sound output unit 192.

2. (1) Game system The game system of this embodiment is a game system for performing a multiplayer battle game with a plurality of game machines. In the game system of this embodiment, the character object (player character) that is the operation target of the player of each game machine attacks the character object (player character of the other player) that is the operation target of the player of the other game machine. A battle game is performed in which the character object is damaged to decrease the physical strength value of the character object. Then, based on the physical strength value of each character object, a process of determining whether each player wins or loses is performed.

  FIG. 2 shows an example of the game system of this embodiment. In the game system of the present embodiment, a plurality of game machines including the game machines 11, 12, 13, and 14 are connected via the network 10 such as the Internet, and an online battle game can be performed. Adopting a peer-to-peer game system in which each game machine 11, 12, 13, 14 participating in an online competitive game can directly communicate with each other via the network 10 to share data Also good.

  In the present embodiment, a detection result of input information from a player who operates the game machine among the first game machine 11, the second game machine 12, the third game machine 13, and the fourth game machine 14. Each game machine performs a game operation in which a plurality of character objects existing in the same virtual three-dimensional space compete based on the input data of the own machine and game data received from another machine. Do.

  The first game machine 11, the second game machine 12, the third game machine 13, and the fourth game machine 14 may be, for example, commercial game machines placed in an amusement facility or a personal computer at home. Or a game terminal.

  Here, the game data corresponds to player input information such as detection signals detected by key inputs such as direction keys and first to n-th buttons, and detection results of key inputs for each frame. Information converted into a command and information that there is no input information (for example, “no key input” information) are also included.

  In the present embodiment, in each of the first game machine 11, the second game machine 12, the third game machine 13, and the fourth game machine 14, each player has a first character object in the virtual three-dimensional space, An online battle game can be played by operating the second character object, the third character object, and the fourth character object.

  For example, the first game machine 11 is based on the data (game data) input to the first game machine 11, and the first character object (the operation target of the player using the first game machine 11). Player game) movement / motion calculation and the like, and the game data of the first game machine 11 is transferred via the network 10 to the second game machine 12, the third game machine 13, and the fourth game machine. 14 is transmitted. In addition, the first game machine 11 receives the second character object (second game machine) based on the game data of the second game machine 12, the third game machine 13, and the fourth game machine 14 received via the network. A player character to be operated by a player using the game machine), a third character object (player character to be operated by a player using the third game machine), and a fourth character object (fourth game machine). The game calculation such as movement / motion calculation of the player character to be operated by the player to be used is performed. Also, in the second game machine 12, the third game machine 13, and the fourth game machine 14, as with the first game machine, the game data input to the own machine and the game data received from another machine Based on the above, game calculation processing is performed.

(2) Multiplayer Battle Game This embodiment will be described by taking a case where a plurality of players (here, four players) play a battle game in a battle royal format (here, the top two players win). Each player performs an operation input from the operation unit of the own device, thereby operating a character object that is a player character of the own device, and operating another character object (an operation input from another device by another player). Play against a character object. When damage is received by the battle, the physical strength value of each character object decreases. When a predetermined value (for example, 0) is reached, the player operating the character object is over the game. If the physical strength value of any of the other two character objects becomes a predetermined value (for example, 0) or the physical strength value enters the top two players when the game period elapses, the player can still win and continue to play.

  FIG. 10 is a diagram schematically illustrating a state in which a plurality of character objects 210 to 240 exist in the virtual three-dimensional space 300.

  The first character object 210 is a character object (player character of the first game machine) operated by the player of the first game machine, and the second character object 220 is operated by the player of the second game machine. The third character object 230 is a character object (a player character of the third game machine) that is operated by the player of the third game machine. The fourth character object 240 is a character object (a player character of the fourth game machine) operated by the player of the fourth game machine.

  The character objects 210 to 240 operated by the players of each game machine exist in the same virtual three-dimensional space, but the image displayed on each game machine is a virtual object that follows the character object that is the player character of each game machine. It is good also as an image of virtual three-dimensional space seen from the camera. If it does in this way, the game image centering on a player character can be displayed on the display part of each game machine.

  The game image of the first game machine is an image obtained by viewing the virtual three-dimensional space from the virtual camera 212 following the first character object 210, and the game image of the second game machine is displayed on the second player character 220. The virtual camera 222 follows the virtual three-dimensional space, and the game image of the third game machine is the virtual three-dimensional space viewed from the virtual camera 232 following the third player character 230. The game image of the fourth game machine may be an image obtained by viewing the virtual three-dimensional space from the virtual camera 242 that follows the fourth player character 240.

  FIG. 3 is an example of the game image of the present embodiment.

  The game image in FIG. 3 is a game image generated by the first game machine, and shows a state in which the first character object 210 is playing against the second character object 220.

  The game image generated by the first game machine is an image obtained by viewing the virtual three-dimensional space from the virtual camera 212 (see FIG. 10) that follows the first character object 210. Although there are a total of four character objects in the virtual three-dimensional space, the game image includes the first character object 210 and the second character object 220 that are within the field of view of the first virtual camera 212. Is displayed on the display unit of the first game machine.

  The game image displays physical strength gauges 260, 270, 280, 290 of the four character objects 210, 220, 230, 240 participating in the battle game. On the side of the physical strength value gauge (near), marks (which may be facial images of character objects) 262, 272, 282, and 292 indicating each character object are displayed, and which physical strength value gauge corresponds to which character object. It is possible to grasp at a glance.

  For example, the physical strength value gauge 260 of the first character object 210 that is the player character of the first game machine (own device) may be displayed on a larger scale than the physical strength value gauges 280 and 290 of the other character objects. Further, for example, the physical strength value gauge of the second character object 220 that is the action target of the first character object 210 that is the player character of the first game machine (own device) is 280 from the physical strength value gauges of other character objects. You may display on a larger scale than 290.

  As shown in FIG. 3, when the first character object 210 is playing against the second character object 220, the action target of the first character object 210 is the second character object 220. The action target of the second character object 220 is the first character object 210. The action target is the current opponent or target, and when a command is input to a given character object, the attack indicated by the command against the character object for which the given character object is set as the action target Or defend. For example, when the player of the first game machine inputs an attack / defense command, the first character object performs an attack defense action on the second character object as the action target, and the player of the second game machine When an attack / defense command is input, the second character object performs an attack defense operation on the first character object that is the action target.

  In this embodiment, a predetermined attack or defense or technique is performed in response to an operation input of each button of the operation unit or a combination of a plurality of buttons, an operation input of a button and a lever, or a combination of a plurality of buttons and a lever. The commands associated with the operation input can be executed by performing the operation input from the operation unit.

  FIG. 13 is an example of the operation unit of each game machine. The operation unit 300 of each game machine may include a lever 310, buttons, etc. 320 to 328.

  The player of each game machine operates the lever 310 and the buttons 320 to 328 of the operation unit 300 of the own machine to perform operation input, thereby causing the character object that is the player character of the own machine to be displayed in the virtual three-dimensional space 200. It can be moved and operated freely.

  For example, the operation unit may be provided with a lever 310 that can indicate eight directions including front, rear, left, and right, and the lever 310 may be operated to move the character object that is the player character of the player in the virtual three-dimensional space. Further, various buttons may be operated to input an attack or defense command, and the character object that is the player's player character may perform an attack / defense operation corresponding to the command.

  For example, a batting command may be input by pressing the first button 320 to cause the character object that is the player character to perform a batting attack on the character object that is the action target. Further, for example, a bullet command may be input by pressing the second button 322, and the character object that is the player character may be caused to perform a shooting attack on the character object that is the action target.

  Further, when executing a command, an action target that is an attack partner (target) of a character object that is a player character may be set and changed by an input from the player.

  FIG. 14 is a diagram for explaining setting of an action target.

  In the present embodiment, the action target can be switched by pressing the fourth button of the operation unit. As shown in FIG. 14, the four player characters participating in the battle game are ordered for convenience, and the character object ordered next to the given character object is the action target of the given character object by default. The action target of a given character object may be changed to the next ordered character object each time the player presses the fourth button.

  In this way, the action target of the first character object at the time of default is the second character object. Therefore, when the player issues a command without switching the action target, The execution target is the second character object. When the player presses the switching button (when the switching button is pressed once), the third character object that is the character object of the next order becomes the action target of the first character object. When the player further presses the switching button (when the switching button is pressed twice), the fourth character object, which is the character object of the next rank, becomes the action target of the first character object. .

(3) Predetermined command An example in which the predetermined command is a throwing command for a character object of a third party (other than the command execution subject and its action target) will be described.

  4 to 6 are game image examples when executing a predetermined command (throwing command to a third party).

  When a throwing command (an example of a predetermined command) for a third party is input from a player of the first game machine, as shown in FIG. 4, a first character object 210 that is a player character of the first game machine. Approaches the second character object 220 that is the action target, grabs the opponent, and, as shown in FIG. 5, a third character object that is a character object other than the first character object 210 and the second character object 220 The second character object 220 is thrown toward 230 (second character action target of the first character object 210), and the second character object 220 is near the third character object 230 as shown in FIG. Moved to.

  The throwing may be executed when a predetermined condition is satisfied. For example, it is determined whether or not a predetermined condition is satisfied based on the defense content of the second character object to be the action target and the parameters (for example, physical strength value and positional relationship) of the first character object and the second character object. When the predetermined condition is satisfied, the first character object may throw (or move) the second character object to the target position.

  The target position 350 to which the second character object 220 is moved is based on the position of the third character object 230 and is close to the third character object 230 (for example, within a predetermined distance from the position of the third character object 230). May be set. For example, it may be set to a position (for example, a position or a relative position defined in the local coordinate system of the third object) that is in a predetermined positional relationship with the position of the third character object 230, or the third character object 230. Any location within a predetermined distance from the position may be set at random. The representative point of the third character object 230 may be set.

  Here, the character object to be the secondary action target (third person) may be designated by the player of the first game machine by input. Further, it may be determined uniquely based on the relationship with the first character object or the second character object, or may be determined based on the positional relationship of each character, the distance from another character, or the physical strength value. Good. For example, a character object that is further away (longer distance) from the first character object may be determined as a secondary action target, or a character object that has a higher physical strength value is determined as a secondary action target. It may be determined randomly.

  Here, an example in which designation can be made by input will be described. For example, when the current action target is the second character object, by default, the third character object (see FIG. 14) positioned in the next order is set as the secondary action target, and during the predetermined period (throwing motion) When the action target switching button is pressed in the middle), the secondary action target may be switched. For example, since the current action target is the second character object, when the player presses the action target switching button (when the switching button is pressed once), the fourth character that is the character object of the next order When the object becomes a secondary action target and the player further presses the switching button (when the switching button is pressed twice), the third character object (the first character object) of the next rank The first character object and the second character object are excluded from the target, so the order may be skipped), but may be the secondary action target of the first character object.

  The second character object 220 is a third action target that is a secondary action target along the movement path 360 (line connecting the current position of the second character object 220 and the target position 350) set with respect to the target position 350. The character object 330 is moved to the vicinity. During this period (from when a predetermined condition is satisfied until the movement of the second character object is completed), the second character object is in an uncontrollable state (a state that cannot be controlled by an operation input from the second game machine). You may leave it.

  In addition, before the execution of the throwing command for the third party, the action target of the second character object 220 is set to the first character object 210. However, the second character object 220 is set by the execution of the throwing command for the third party. The action target of the object 220 may be forcibly changed to the third character object 230 (changed without input from the player of the second game machine).

  In this way, after execution of the throwing command for the third person, the second character object 220 is located near the third character object 230 as shown in FIG. Is set. Since the second character object 220 as a new enemy appears near the third character object 230 as the player character of the third game machine, the player of the third game machine sets the action target of the third character object 230 as an action target. Switching to the second character object 220 increases the possibility of playing against the second character object. That is, by the command input of the player of the first game machine, the second character object 220 that is the player character of the player of the second game machine and the third character object that is the player character of the player of the third game machine It is possible to set a situation in which the player can easily compete with the player 230.

  FIG. 15 is a time chart showing the flow from the input of a predetermined command (throwing command for a third party) to the end of execution.

  When a predetermined command (throwing command for a third party) is input from the player of the first game machine at time t1 (S1), the first character object and the action target are displayed at time t2 after the period K1. Based on a predetermined parameter (for example, a physical strength parameter) of the second character object, it is determined whether a predetermined condition is satisfied (S2). During the period K1, the player of the second game machine can operate the second character object, and can input a defense command, for example. When a command is input from the player of the second game machine, it may be determined whether or not a predetermined condition is satisfied, including a command input by both players and a parameter change caused by the command. For example, when the two physical strength parameters at time t2 are compared and the physical strength value of the first character object exceeds the physical strength value of the second character object 220 by a predetermined reference, the predetermined condition is satisfied. You may judge.

  If the predetermined condition is not satisfied, the predetermined command is unsuccessful, and the execution of the command is terminated there. That is, the process does not proceed to steps S3 to S5, and the first character object does not throw the second character object 220 object and move it.

  When the predetermined condition is satisfied, the first character object performs the throwing motion during the period K2. As the throwing motion, for example, a motion in which the first character object swings around the second character object may be performed. During this time, the player of the first game machine can switch the throwing target (secondary action target of the first character object) by operating the operation unit. At time t3 after the period K2, the throwing target (secondary action target of the first character object) is determined, and the target position is determined accordingly (S3).

  When the target position is determined, the first character object performs a post-throw motion during the period K3. The post-throw motion may be a motion in which the first character object throws the second character object toward the determined target position. Note that the length of the period K3 may be variably set. For example, it may be changed according to the direction of the target position.

  Then, at time t4, the second character object leaves the hand of the first character object and starts moving toward the target position, reaches the target position at time t5 after a predetermined period K4, and ends the movement. . This completes the operations of the first character object and the second character object that are caused in response to a predetermined command (throwing command for a third party). Note that the length of the predetermined period K4 may be set variably. For example, it may be changed according to the distance to the target position (for example, the longer the distance, the longer the predetermined period K4).

(4) Movement Path of Action Target FIGS. 20A and 20B are diagrams for explaining a movement path correction process when a throwing command (an example of a predetermined command) for a third party is executed.

  When a throwing command for a third party is executed, based on the position of the target character object (here, the second character object 220) of the given character object (here, the first character object 210) and the target position 350, The movement path 360 of the action target character object (here, the second character object 220) may be calculated to determine whether or not there is an object that becomes an obstacle on the movement path 360.

  The movement path may be a straight line or a curve (for example, a parabola or a line obtained by a predetermined trajectory function). When there is no obstacle on the movement path, a process of moving the second character object to the target position may be performed.

  For example, as shown in FIGS. 20A and 20B, when there is an object 370 that becomes an obstacle on the movement path 360, a movement path correction process for correcting the movement path may be performed.

  For example, as shown in FIG. 20A, the movement path may be corrected by correcting only the intermediate path (correction from 360 to 360 ') without changing the target position 350. Further, for example, as shown in FIG. 20B, the target position may be changed (350 → 350 ′).

  For example, when the movement path before correction is set as a straight line connecting the second character object 220 and the target position 350, as shown in FIG. 20A, the straight movement path 360 is set as an obstacle object. You may correct | amend to the moving path | route 360 'of the curve which avoids 370 and passes. Further, as shown in FIG. 20B, correction may be performed by changing the direction of the straight movement path by a predetermined angle θ.

  FIGS. 11A and 11B and FIGS. 12A and 12B are diagrams for explaining processing when an obstacle exists on the moving route.

  As shown in FIG. 11A, when there is an object 372 serving as an obstacle on the movement path 360, the second character object 220 is changed as shown in FIG. 11B without changing the movement path 360. If the object 372 that becomes an obstacle is hit, a process of destroying or extinguishing the object 372 (372 ′ is an object after destruction) may be performed.

  Further, it may be determined whether or not destruction or disappearance is possible according to the attribute of the object that becomes an obstacle on the moving route. If the object 374 on the movement path has an attribute that can be destroyed or disappeared, as shown in FIG. 12A, the object 374 on the movement path 360 is destroyed or disappeared without changing the movement path 360. Processing may be performed. When the object 374 on the movement path has an attribute that cannot be destroyed or disappeared, the movement path may be corrected (corrected from 360 to 360 ') as shown in FIG.

  Note that attribute information for determining whether destruction or extinction is possible may be set in advance for each object. For example, determine whether an object that can be an obstacle (for example, a map object, a terrain object such as a rock or a mountain, a structure object such as a building, or a tree object) can be destroyed or extinguished. Attribute information may be set.

  As an object destruction process, for example, when a moving character object and an obstacle object collide, an image effect is performed in which the obstacle object is destroyed, and the obstacle object is divided into a plurality of fragment objects. You may change to the state decomposed | disassembled into (state in which the object was broken).

  FIG. 7 and FIG. 8 are examples of game images when a throwing command to a third party (an example of a predetermined command) destroys an object that becomes an obstacle when a predetermined command is executed. It is an example of a game image in the case of destroying the object used as an obstacle at the time of execution.

  As shown in FIG. 7, there is an object (tree object) 372 serving as an obstacle on the movement path of the second character object 220 thrown away, and an object (tree object) serving as the obstacle as the second character object 220. When hitting 372, as shown in FIG. 8, an image effect may be performed in which an object (tree object) 372 (a tree object 372 ′ after destruction) serving as an obstacle is destroyed.

  In addition, as a process for annihilating an object that becomes an obstacle, for example, when a moving character object and an object that becomes an obstacle collide, an image effect that causes the object to disappear is performed, and a predetermined period (for example, until the game ends) During the period of (), the object after disappearance may not be displayed.

(5) Motion Correction Processing FIGS. 16A to 16C are diagrams for explaining motion correction of a given object.

  In this embodiment, after a predetermined command (throwing command for a third party) is input, the throwing target (secondary action target of the first character object) can be switched for a predetermined period. The direction of the first character object during the throwing motion differs depending on the direction of the character. The position to be thrown can be in any direction around 360 degrees around a given character object. Therefore, it is also possible to prepare motions corresponding to a plurality of directions in advance and select and execute a motion in the direction closest to the game situation.

  Alternatively, only one pattern of motion data of a reference throwing motion may be prepared, and the reference throwing motion may be corrected and used according to the direction of the target to be thrown. In this way, an increase in motion data can be prevented.

  For example, it is assumed that the reference throwing motion is a rotational motion that rotates once in the clockwise direction from the reference direction 410 as shown in FIG. 16A while the first character object lifts the second character. To do. As the throwing motion in the period K2 in FIG. 15, first, the first character object performs a lifting motion that lifts the second character object, and then performs the rotational motion n times so that the first character object becomes the second motion. An action of lifting the character object and rotating it n times can be expressed. After that, as a later-described throwing motion in the period K3, a rotational motion is performed up to the direction of the target for throwing (the direction corresponding to the target position), and when the direction of the target for throwing is reached, the second character object is thrown away. By performing a motion to let go in the direction of, it is possible to express the motion of throwing while rotating.

  For example, as shown in FIG. 16B, when the object to be thrown (secondary action object of the first character object) is 230, rotation by θ1 from the reference direction 410 becomes the direction 412 of the object to be thrown 230. The motion data may be corrected and used so that the motion is performed for θ1 and the second character object is thrown in the direction of the target.

  Also, for example, as shown in FIG. 16C, when the target to be thrown (secondary action target of the first character object) is 240, the direction 414 of the target to be thrown becomes 414 when rotating from the reference direction 410 by θ2. The motion data may be corrected and used so that the rotation motion is performed for θ2 and the second character object is thrown in the direction of the target 240 to be thrown.

  FIGS. 17A to 17C are diagrams for explaining the direction correction of a given character object.

  For example, as the motion of a given character object, as shown in FIG. 17A, a throwing motion for throwing the action target character object in the throwing direction 420 is prepared, and the direction of the throwing target (direction corresponding to the target position) ), The direction at the start of the motion may be corrected. For example, during the period K2 in FIG. 15, the motion before throwing is performed, and when the throwing direction is determined at time t3, the direction of the given character object at the start of the throwing motion is corrected according to the throwing direction.

  For example, the motion may be temporarily interrupted at time t3 in FIG. 15, and the direction of a given character object may be corrected based on the determined target position.

  For example, as shown in FIG. 17B, when the throwing target (second character target of the first character object) is the third character object 230, the direction of the given character object is set to the third character object 230. It may be corrected in the direction 422.

  For example, as shown in FIG. 17C, when the throwing target (secondary action target of the first character object) is the fourth character object 240, the direction of the given character object is set to the fourth character object. 240 may be corrected in the direction 424.

(6) Enemy notification image display When a given character object is the action target of another character object, a process of displaying an enemy notification image for notifying the character object having the character object as an action target is performed. May be.

  The enemy notification image may be an image that allows the character object being the action target to be grasped. An enemy notification image for notifying an enemy who is aiming at a character object that is a player character of each player may be displayed on the display unit of each player.

  FIG. 21 shows an example of a game image on which an enemy notification image is displayed.

  For example, when four character objects 210, 220, 230, and 240 play a battle, the action target of the first character object 210 is the second character object 220, and the action target of the second character object 220 is the first character. It is assumed that the action target of the object 210 and the third character object 230 is the first character object 210 and the action target of the fourth character object 240 is the third character object 230. In such a case, on the game screen of the first game machine, an enemy notification image 440 for notifying the second character object 220 and the third character object 230, which are targets of the action of the first character object 210, as an enemy. , 442 may be displayed in association with the second character object 220 and the third character object 230, respectively.

  In this way, each player can visually grasp the character object that is aiming at the character object that is his / her player character on his / her game screen, so that quick movement and attack defense are performed. be able to.

  In the above embodiment, an example is shown in which the mark image displayed along with the character object that is the action object of the character object that is the player character of each game machine is the enemy notification image on the game screen of each game machine. Although explained, it is not restricted to this, Another mark image may be sufficient and a character image may be sufficient.

  In addition, a character object other than the player character and a character object other than the player character (this is a player character) A line image connecting the character objects may be generated.

  FIG. 9 shows an example of a game image on which a line image is displayed.

  For example, when four character objects 210, 220, 230, and 240 play a battle, the action target of the first character object 210 is the second character object 220, and the action target of the second character object 220 is the first character. It is assumed that the action target of the object 210 and the third character object 230 is the first character object 210 and the action target of the fourth character object 240 is the third character object 230. In such a case, on the game screen of the player of the first game machine, a line image 450 that connects the first character object 210 to the second character object 220 that is the action target of the first character object 210, the first image A line image 452 is generated that connects the third character object 230 and the first character object 210 that have the character object 210 as an action target. In addition, a line image 456 that connects the fourth character object 240 and the third character object 230 that are the action target of the third character object 230 is generated. However, a line image that connects the first character object 210 (player character) and the second character object 220 that is the action target is not generated.

  In this way, when the character object that is the player character of the own device is the action target of another character object, a line image is generated between the other character object and the character object that is the player character of the own device. Therefore, there is an effect that it becomes easy to visually grasp the positional relationship between the character object that is the player character of the player's own machine and the other character object aiming at the character object.

  When a character object that is a player character of another machine is an action target of a character object other than the own machine, a line image is displayed between the other character object and the character object that is a player character of the other machine. Generated. In this way, there is an effect that it is easy to visually grasp the battle situation between the character object which is the player character of the other machine and the other character object other than the own machine aiming at the character object.

  Since a line image is not generated between the character object that is the player player character and the character object that is the action target, it is possible to prevent the line image from increasing excessively and making it difficult to view the game image.

  In addition, the line image provides a line image in which the target side and the target side can be grasped at a glance by giving an arrow that can identify the direction of the line (direction and direction of the line). be able to.

(7) Control of virtual camera at the time of execution of predetermined command When a given character object executes a predetermined command on the character object to be acted on, the given character object, the character object to be acted on, and the two Based on the position of the next action target character object, the position (at least one of position and orientation) of the virtual camera may be set.

  FIG. 22 is a diagram for explaining virtual camera arrangement control when a predetermined command is executed. A game image of the first game machine (a game image displayed on the display unit of the first game machine using the first character object 210 as a player character) is a first virtual camera that follows the first character object. An image of the virtual three-dimensional space viewed from 212 is obtained. There are four character objects 210, 220, 230, and 240 in the virtual three-dimensional space. However, since the virtual three-dimensional space is large, the first virtual camera 212 has the first character object 210 and its action. The target character object (here, the second character object 220) is arranged at a position and orientation that fall within the visual field range. However, when the player of the first game machine inputs a predetermined command, the character object that is the secondary action target that is the destination of the action target (throwing target) is also in the position and orientation that fall within the field of view. The virtual camera 212 is arranged. When the character object that is the target of the secondary action is changed at the time of executing the predetermined command, the first virtual camera is placed at the position and orientation in which the character object that is the target of the secondary action after the change falls within the visual field range. The arrangement of 212 is changed.

  At the time of executing a predetermined command, at least one of the position and orientation of the first virtual camera 212 according to the position of the first character object 210, the action target (second character object 220), and the secondary action target. By determining, it is possible to generate an image in which these character objects fall within the visual field range.

  For example, when the secondary action target is the third character object 230, the position where the first character object 210, the second character object 220, and the third character object 230 fall within the visual field range (490-1). The first virtual camera 212 is arranged in the direction (see 212-1).

  For example, when the secondary action target is the fourth character object 240, the first character object 210, the second character object 220, and the fourth character object 240 are within the field of view (490-2). The first virtual camera 212 is placed at the position and orientation to enter (see 212-2).

  When the secondary action target is switched from the third character object 230 to the fourth character object 240 during the command execution, the arrangement of the virtual camera may be switched from 212-1 to 212-2.

(8) Process Flow FIG. 18 is a flowchart showing the flow of a predetermined command execution process (throwing command for a third party).

  When a predetermined command is input for a given character object, the following processing is performed (step S10).

  Based on the parameters of the given character object and the character object that is the action target, it is determined whether or not a predetermined condition is satisfied (step S20). For example, the action target may be determined by the method shown in FIG. The determination of the predetermined condition may be performed after a period K1 has elapsed since the input of the predetermined command as shown in FIG. If there is an input from the player who operates the character object that is the action target within this period K1, the predetermined condition may be determined in consideration of the change in the parameter of each character object depending on the input content. .

  If the predetermined condition is satisfied (step S22), the first-time throwing motion for a predetermined period (period K2 in FIG. 15) is executed, and the character object to be acted is made uncontrollable (step S30). Therefore, after this (after time t2 in FIG. 15), control is performed so that the operation input to the action target character object is not reflected until the predetermined command execution is completed (time t5 in FIG. 15).

  If there is a change input of the character object that is the secondary action target (target position) during the first-row throwing motion for a predetermined period (Y in step S40), the secondary action target after the change is input. Based on the position of the character object, the target position is determined (step S50), and the action target of the action target character object is changed to the character object of the secondary action target after the change (step S60). If there is no change input of the character object to be the secondary action target (target position) during the first-row throwing motion for a predetermined period (N in step S40), the secondary action target set at the time of command input The target position is determined based on the position of the character object (step S70), and the action target of the action target character object is changed to the secondary action target character object set when the command is input (step S80).

Based on the determined target position, a late-throw motion is executed to move the action target character object to the target position (step S90).
When the action target character object reaches the target position, the uncontrollable state is canceled (step S100).

  FIG. 19 is a flowchart showing the flow of a movement path determination process for an action target when a predetermined command (throwing command for a third party) is executed.

  Based on the action target character object and the target position, the movement route is calculated, and it is determined whether or not an object that becomes an obstacle exists on the movement route (step S110).

  If there is an obstacle object on the movement path (Y in step S120), it is determined whether the obstacle object has a destructible or extinct attribute (step S130). A process of moving the action target character object to the target position along the movement path is performed, and an obstacle object destruction or disappearance process is performed when the action target character object and the obstacle object hit. (Step S140)

  If there is an object that becomes an obstacle on the movement path (in the case of Y in step S120), and the object that becomes an obstacle does not have a destructible or extinct attribute (N in step S130), the target position and the movement path Correction is performed (step S150).

  When there is no obstruction object on the movement path (in the case of N in step S120), a process of moving the action target character object to the target position along the movement path is performed (step S160).
