Technical Field
The invention relates to the technical field of role control, in particular to a method, a system and a medium for dynamically detecting and controlling the direction of virtual characters at multiple angles.
Background
The follow camera viewing angle adjustment technique is a technique commonly used in video production and game development. It allows the camera to dynamically adjust the viewing angle according to specific rules or user inputs in order to better follow a specific object or scene. In game development, the following camera view angle adjustment technique is often used to realize view angle control of player characters. For example, in a third person action game, the camera typically follows the movement of the player character, keeps the character always in the center of the screen, and adjusts appropriately according to the needs of the scene. This may provide a better gaming experience and may make it easier for players to take care of the character and environment.
Particularly, in the third view angle, in order to ensure that the moving operations such as the forward and backward movement of the character can be used as a reference according to the current view angle direction of the user, the character always needs to keep consistent with the view angle direction of the camera, but in practical application, there are various use requirements, sometimes the user only wants to rotate the view angle of the camera, but does not need to rotate the direction of the character, the conventional solution is to disengage the rotation remote control of the view angle of the camera from the direction rotation remote control of the character by pressing a designated key, so that the direction of the character can be freely rotated to ensure that the direction of the character is unchanged. Thus, the existing avatar orientation control cannot meet various demands.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Example 1
As shown in fig. 1, a method for dynamically detecting and controlling the orientation of a virtual character at multiple angles includes the following steps:
in the step S1, a direction vector N of a target person in the virtual scene and a camera view angle vector M are obtained, wherein in the virtual scene, the direction vector N is a normal vector of a center point of the virtual person toward the right front, and the camera view angle vector M is a normal vector of a center point of the camera toward the right front. In the virtual scene, the movement of the virtual character and the rotation of the camera view angle are independently controlled, taking a computer end as an example, the keyboard can control the displacement of the virtual character, the mouse can control the camera view angle, along with the movement of the mouse, the picture seen by a user rotates, at the moment, the camera view angle vector M changes, if the virtual character also rotates, the orientation vector N also changes, and the preparation of the orientation of the character following the camera view angle is made by firstly acquiring the orientation vector N and the camera view angle vector M.
Step S2, dynamically detecting the camera visual angle, wherein the dynamic detection comprises visual angle rotation detection and operation stop detection, the visual angle rotation detection is used for recording a direction vector M1 when the camera visual angle starts to rotate and a direction vector M2 when the camera visual angle ends to rotate, a rotation angle alpha is calculated according to the M1 and the M2, and the operation stop detection is used for detecting the holding time t when the camera visual angle stops rotating; the method comprises the steps of detecting the camera visual angle in real time, including visual angle rotation detection and operation stop detection, wherein the visual angle rotation detection is used for detecting whether a user operates a visual angle picture to deflect, if deflection occurs, the detection does not record a deflection track, but only records a direction vector M1 at the beginning and a direction vector M2 at the end, so that the deflection angle at this time, namely a rotation angle alpha, can be obtained according to the two direction vectors, the rotation animation is played through a pre-designed animation model, the rotation angle alpha is input to the animation model, and the direction vector N at the end after the target character plays the rotation animation is consistent with the direction vector M2.
The rotation angle alpha is used for making reference for the subsequent person orientation control, so that the orientation of the person can be consistent with the direction of the visual angle of the rotated camera, and the rotation angle alpha is needed to determine how much the person needs to rotate; the operation stop detection is to detect whether the target person needs to be controlled to rotate or not after the user operates the visual angle to deflect, namely, the holding time t is utilized to determine whether the target person needs to be controlled to rotate, if the holding time t is too short, the direction of the target person does not need to be controlled to change, otherwise, the control is needed, and the operation stop detection has certain benefits in practical application, for example, when the user operates the virtual person to face a target, the visual angle picture at the moment also faces the target, but the user does not want to leave the target, only wants to see the environment around the target, the user can deflect until the user returns to the original position through the operation visual angle, and certain pause is necessarily generated when the visual angle deflects to a region, and the holding time t is not used for operation, because the user only wants to observe the surrounding environment for a long time, the temporary stop does not cause the direction of the target person to rotate, so that the psychological expectation of the user is achieved, and the detection of the holding time t is more consistent with the practical use condition.
The rotation angle alpha is used as a reference for the consistency of orientation control and is also used for judging whether the target person needs to be controlled to rotate, because in practical application, a user controls the virtual person through a computer end or a head display device, fingers touch a mouse or the head display device shakes to cause a certain tiny deflection of a camera visual angle, and the tiny deflection is not the intention that the user really wants to rotate the camera visual angle, the orientation change of the target person does not need to be controlled, and the method can be more suitable for the practical use condition
Step S3, setting a detection time T and a detection angle beta 1; the detection time T is used for comparison, and in the step S2, it is mentioned that the holding time T is required to be controlled to be consistent with the last direction of the camera view angle only when reaching a certain value, so the detection time T is used for measuring time, a timer is generally used for counting time, a time threshold is set on the timer, that is, the detection time T is set, the timer starts to work after the rotation of the camera view angle is stopped, and when the timer exceeds the set threshold, the holding time T is indicated to be exceeding the detection time T, otherwise, the holding time T is not exceeded.
The detection angle β1 is an angle for detecting rotation of the camera view angle, and the above-mentioned step S2 mentions that the rotation angle α is calculated based on the direction vector M1 at the start and the direction vector M2 at the end, and in the case where the value of the rotation angle α is small, the orientation of the target person is not required to be rotated, so that setting the detection angle β1 in comparison with the rotation angle α indicates that the orientation of the target person is required to be controlled only when the detection angle β1 is exceeded.
The manner of judging whether or not it is necessary to control the rotation of the target person's orientation using the detection time T and the detection angle β1 is specifically as follows:
a1, if T is smaller than T, the orientation vector N of the target person is kept unchanged, and the target person orientation control is performed on the premise that when the user stops rotating the camera view angle for a certain time, the step only needs to judge whether the holding time T reaches the detection time T, does not need to judge the rotation angle alpha, and does not need to control the target person orientation when the holding time T does not reach the standard of the detection time T.
A2, if T is larger than or equal to T and |alpha|β1, the orientation vector N of the target person is kept unchanged, wherein the step is different from the previous step in that the holding time T reaches the standard of the detection time T, the rotation angle alpha is required to be judged, the rotation angle alpha is smaller than the detection angle β1, and the orientation of the target person is not required to be controlled;
a3, if T is equal to or greater than T and |alpha|β1, controlling the target person to execute the rotation animation so that the direction vector N of the target person is consistent with the direction vector M2, and synchronizing the execution of the rotation animation to other users in the virtual scene.
It is noted that in the above-described step A2 and step A3, the rotation angle α is compared with the detection angle β1 by |α| which is the absolute value α and β1, and since the rotation angle α may be set to fall within the range of not only 0 to 360 ° but also 0 to 180 °, in the second case, if the rotation angle α exceeds 180 °, the value of α is smaller than 0, and therefore |α| is selected when compared with β1.
In order to make the judgment of the detection time T and the detection angle beta 1 more accord with the actual use condition, the detection time T is set between 1 and 2s, the detection angle beta 1 is set between 0 and 1 DEG, because the time of 1 to 2s is enough for a user to stay to observe the surrounding environment of a target, the judgment that the user wants to rotate the view angle of the camera to change the direction of the target person can be made only when the time exceeds the time, and likewise, the judgment that the view angle of the camera wants to rotate to change the direction of the target person can be made only when the angle exceeds the time to provide the shaking range allowing the view angle of the camera.
The playing of the rotary animation is a continuous process, when the rotary animation is designed, the playing time length of the complete action is set, the action of rotating can be realized by inputting the rotating angle, and as the playing time length is fixed, the smaller the rotating angle is, the slower the rotating speed of the target person is, whereas the larger the rotating angle is, the faster the rotating speed of the target person is, so that if only one action is adopted to realize the rotation of the target person, the rotating action is easy to lead a user to view the rotation not to be coordinated enough when the angle is smaller, and the following method is provided: as shown in fig. 2, the method further includes setting a detection angle β2, and β1 and β2, wherein the rotation animation includes a first animation and a second animation, the main characteristic of designing the first animation is that the motion amplitude of the person is small, so that the person is not easy to generate uncoordinated sense even under the condition of small rotation angle, and the main characteristic of designing the second motion is that the motion amplitude of the person is large, because the rotation speed of the task is high under the condition of large rotation angle, the uncoordinated sense is not easy to generate when the motion amplitude is large.
The following method is made on how to judge whether the target person should perform the first animation or the second animation:
if T is not less than T and beta 1 is not less than beta 2, controlling the target person to execute the first animation so that the direction vector N of the target person is consistent with the direction vector M2;
if t+.gtoreq.t, |α+|β2, the control target person performs the second animation so that the direction vector N of the target person matches the direction vector M2. The detection angle beta 2 is set to be between 1 and 10 degrees, and the rotation angle in the interval is summarized as the case of small rotation angle and the case of no less than 10 degrees is summarized as the case of large rotation angle.
In step S2, it has been mentioned that the view angle rotation detection does not record the trajectory of deflection, only the direction vector M1 at the beginning and the direction vector M2 at the end are recorded, and also in step A2 and step A3, it is mentioned that the rotation angle α may be set to fall within the range of not only 0 to 360 ° but also 0 to 180 °, so that in order to improve the orientation efficiency of the control target person, the rotation angle α is selected to fall within the range of 0 to 180 ° optimally because the rotation angle does not exceed 180 °, the rotation efficiency is better, but the selection of the range of 0 to 180 °, a problem that if the user manipulates the camera view angle rotation exceeding 180 °, the calculated rotation angle α is a negative value, at which time the orientation of the control target person is inconvenient.
Thus, in response to the above problems, the following improvements have been made:
as shown in fig. 3, the method further includes setting a direction vector M1 at the start of rotation as a reference axis, and if the direction vector M2 at the end of rotation is located at the left half of the reference axis, calculating a rotation angle α < 0 °; if the direction vector M2 at the end of rotation is positioned at the right half of the reference shaft, the calculated rotation angle alpha & gt 0 degrees; if the rotation angle alpha of the input animation model is less than 0 degrees, executing the rotation animation to rotate leftwards, if the rotation angle alpha of the input animation model is greater than 0 degrees, executing the rotation animation to rotate rightwards, dividing the rotation area of the target person into two parts, namely a left area and a right area, taking the direction vector M1 before the rotation of the camera view angle as a central axis, and enabling the angle of the right rotation of the camera view angle to exceed 180 degrees, enabling the camera view angle to reach the left area from the right area, so that the rotation animation is designed to be in left rotation and right rotation, and judging that the direction of the control target person turns leftwards at the moment is most efficient.
