It should be understood that the block diagram of the computing device shown in FIG. 1 is for exemplary purposes only and is not intended to limit the scope of the present description. Those skilled in the art may add or replace other components as desired.

Computing device 100 may also be a mobile or stationary server.
The processor 120 may perform the steps of the cursor control method shown in fig. 2, including steps S210 to S230.
Step S210: and under the condition that a cursor movement signal is received, acquiring the current simulation position point of the cursor based on the preset cursor reference point timing.
In this embodiment of the present application, taking a cursor reference point as an example, the cursor reference point refers to a point preset in the system, and the position of the cursor reference point may be in an upper left, a lower left, an upper right, a lower right, an upper side, a lower side, a left side, a right side, a middle area, and a system inner area deviating from the middle area in the system. The middle region within the system is a common situation. In any case, the cursor reference point is preset inside the system, and the position of the cursor reference point is not changed when the cursor reference point is used for calculation. The cursor current simulation position point is obtained by generating displacement based on a preset cursor reference point and a cursor movement signal obtained at fixed time, and the position of the cursor current simulation position point is not fixed in each calculation.
Under the condition that the cursor movement signal is not received, the cursor movement signal is not acquired, and the displacement generated by the cursor movement signal cannot be acquired. Under the condition that the cursor movement signal is received, the displacement generated by the cursor movement signal is collected, and the movement track of the cursor movement can be straight line, curve, combination of straight line and curve, and is not limited in the embodiment. For example: in a game scene, when a user cursor moves, motion information for detecting the movement of the cursor in the system collects displacement generated by a cursor movement signal.
In practical application, the displacement generated by the cursor moving signal in the current sampling period can be determined by acquiring the current analog position point of the cursor based on the preset cursor reference point according to the set sampling frequency; and determining the current simulation position point of the cursor according to the preset cursor reference point and the displacement.
In an embodiment of the present application, based on a preset cursor reference point, position information of a current analog position point of a cursor is obtained at fixed time, a sampling frequency is preset in a system, and under the condition that a cursor movement signal is received, motion information when the current cursor moves is collected according to the sampling frequency set by the system, that is, displacement generated when the cursor moves is collected according to the sampling frequency set by the system every second, and the sampling frequency is different according to different application conditions. After the sampling frequency is determined, the sampling period is also determined as the reciprocal of the sampling frequency, the sampling period is the time interval when the cursor is moved, and when the information of the cursor movement is collected, the displacement generated when the cursor is moved is determined in the current sampling period according to the sampling frequency set in the embodiment.
In an embodiment of the present application, the movement track of the cursor is various when the cursor moves, but the displacement generated by the movement of the cursor is irrelevant to the movement track of the cursor, and only relevant to the starting point and the end point of the cursor.
For example: in a game scene, a cursor moves in an area, the movement of the cursor can control the movement state of a character in the game, and the movement track of the cursor in the area is various: when the cursor movement track is a curve, the movement action of the character in the cursor control game can be visual field rotation; when the cursor movement state is a straight line, the movement of the character can also be visual field rotation; when the motion state of the cursor is that the curve and the straight line are mutually kneaded, the motion action of the character can also be that the visual field rotates.
Step S220: and calculating a distance vector between the current simulated position point of the cursor and the reference point of the cursor.
In an embodiment of the present application, after the current simulated position point information of the cursor is determined according to the displacement generated by the cursor reference point and the cursor movement signal, the distance vector between the current simulated position point of the cursor and the cursor reference point is calculated, and the calculation process is implemented by a calculation program in the system. And after the current simulated position point of the cursor is acquired, a calculation program is called, and the distance vectors of the two points are calculated based on the determined current simulated position point of the cursor and the position information of the cursor reference point.
Step S230: and setting the current simulated position point of the cursor back to the cursor reference point, determining the rotation angle of the visual field based on the distance vector, and controlling the rotation of the visual field of the system according to the rotation angle of the visual field.
In an embodiment of the application, after one calculation is completed, the current simulated position point of the cursor is reset to the position of the cursor reference point, after the reset is completed, the current simulated position point of the cursor is identical to the position information of the cursor reference point, and the current simulated position point of the cursor is reset to the cursor reference point, so that the situation that the cursor moving signal cannot be acquired to generate displacement after the current simulated position point of the cursor is positioned at the boundary of the system area is avoided. And thus the position information of the current analog position point of the cursor cannot be determined according to the cursor reference point. For example: in a game scene, when a user drags a cursor, the displacement generated by a cursor movement signal changes along with the movement of the cursor of the user, at the moment, the motion information of the current simulation position point of the cursor also changes, and the angle of rotation of the field of view of a character in the game also changes after the distance vector between the current simulation position point of the cursor and a cursor reference point changes. However, if the current simulated position point of the cursor is not returned to the position of the cursor reference point, when the cursor of the user moves, the system cursor moves to the boundary of the area, and the displacement of the cursor movement signal cannot be acquired, and at this time, the rotation angle of the visual field of the character in the game does not change with the movement of the cursor of the user. After each calculation is completed, according to the calculation method of setting the current simulated position point of the cursor back to the reference point of the cursor, the displacement signal of the cursor movement can be continuously collected, so that the rotation angle of the visual field is determined based on the generated distance vector, and the rotation of the visual field of the system is controlled according to the rotation angle of the visual field.
According to the cursor control method, the cursor reference point is preset in the system, the current simulation position point of the cursor is obtained based on the timing of the cursor reference point, after the position information of the current simulation position point of the cursor and the cursor reference point is determined, the visual field rotation angle is rotated by calculating the distance vectors of the two points, after the cursor reaches the boundary of the area, in order to obtain the displacement vector generated by the cursor moving signal, after each calculation is completed, the current simulation position point of the cursor is reset to the cursor reference point. When the user moves the cursor, the user drags the cursor in the original direction to be regarded as effective operation, and the cursor is continuously presented according to the original visual field rotation effect, so that the user experience is improved.
Another embodiment of the present application discloses a cursor dragging method, as shown in fig. 3, including steps S310 to S360.
Step S310: and under the condition that a cursor movement signal is received, acquiring the current simulation position point of the cursor based on the preset cursor reference point timing.
In practical application, the displacement generated by the cursor moving signal in the current sampling period can be determined according to the set sampling frequency; and determining the current simulation position point of the cursor according to the preset cursor reference point and the displacement.
Step S320: and calculating a distance vector between the current simulated position point of the cursor and the reference point of the cursor.
Step S330: and setting the current simulated position point of the cursor back to a cursor reference point, and controlling the rotation of the system vision according to the vision rotation angle based on the matching of the vision rotation angle based on the distance vector according to a preset correspondence table of the distance vector and the vision rotation angle.
In the game scene, the motion state of the character is controlled by controlling a cursor, and the rotation of the visual field is determined according to a preset correspondence table of the distance vector and the rotation angle of the visual field. The correspondence table of the distance vector and the rotation angle of the field of view is already preset inside the system before the cursor movement signal is received.
The correspondence relationship may be various, for example, the correspondence relationship between the distance vector and the rotation angle of the field of view may be linear or nonlinear.
For example, when the correspondence between the distance vector and the view rotation angle is linear, the corresponding view rotation angle can be determined according to one distance vector, and the current view is controlled to continue to rotate by the corresponding view rotation angle.
In practical application, the visual field rotation angle corresponding to the distance vector in the current sampling period can be determined according to the corresponding table by determining the distance vector in the current sampling period, and the visual field rotation angle of the system is controlled.
For example, in the case where the correspondence relationship between the distance vectors and the view rotation angles is nonlinear, the view rotation angles corresponding to the respective distance vectors are different from each other, and in this case, it is necessary to superimpose the distance vectors and obtain an accumulated view rotation angle, and control the current view to be rotated to a position corresponding to the accumulated view rotation angle.
In practical application, determining an accumulated distance vector from a first sampling period to a current sampling period of a received cursor movement signal, determining a visual field rotation angle corresponding to the accumulated distance vector according to the corresponding table, and controlling the system visual field to rotate to the visual field rotation angle.
In a game scene, when a cursor is dragged to generate a displacement vector, a character in the game can also rotate a certain angle along with the movement of the cursor, for example: in the game scene, when the player drags the cursor, if the distance vector generated by the current motion of the simulated position point of the cursor and the rotation angle of the visual field are in regular linear change, for example: when the corresponding relation between the distance vector and the visual field rotation angle is a straight line, one distance vector can uniquely determine the visual field rotation angle, and when the distance vector obtained by calculating the distance vector between the current simulated position point of the cursor and the reference point of the cursor is 0.1, the rotation angle of the corresponding visual field is 36 degrees. When the distance vector is 0.2, the corresponding view rotation angle is 72 degrees. And calling a corresponding relation table which accords with the situation at the moment, determining a visual field rotation angle corresponding to the distance vector in the current sampling period according to the corresponding relation table, and controlling the visual field of the system to rotate by the visual field rotation angle.
If the distance vector generated by the current simulated position point movement of the cursor and the visual field rotation angle are in nonlinear change, one distance vector cannot uniquely determine one visual field rotation angle, and the visual field rotation angle is determined according to the accumulated distance vectors. Such as: when the distance vector generated by the current simulated position point motion of the cursor and the visual field rotation angle are a curve, and when the distance vector is 0.1, the corresponding visual field rotation angle may be 36 degrees, but when the distance vector is 0.6, the corresponding visual field rotation angle may also be 50 degrees, at the moment, the visual field rotation angle is to be determined, the distance vectors are to be overlapped, a corresponding relation table which accords with the situation at the moment is called, the visual field rotation angle corresponding to the accumulated distance vector is determined according to the corresponding table, and the visual field rotation of the system is controlled to be rotated to the visual field rotation angle.
Step S340: when the cursor movement signal is received, it is determined whether the next actual position point of the cursor exceeds the boundary of the display area according to the displacement vector in the current sampling period and the current actual position point of the cursor, if so, step S350 is executed, and if not, step S360 is executed.
Step S350: and moving the cursor to the boundary of the display area according to the direction of the displacement vector and the current actual position point of the cursor.
Step S360: the cursor is controlled to move to the next actual position point.
In an embodiment of the present application, taking the current actual position point of the cursor as an example, the current actual position point of the cursor may be in an upper left, a lower left, an upper right, a lower right, an upper side, a lower side, a left side, a right side, a middle area and a deviated middle position of the display area, where the current actual position point of the cursor is not limited in the embodiment of the present application, and under the condition that a cursor movement signal is received, the position information of the current actual position point of the cursor and the displacement generated by the movement of the cursor in the current sampling period are used to determine the position information of the current actual position point of the cursor after the next cursor movement, and the position information of the current actual position point of the cursor and the value of the displacement vector are combined to obtain the next actual position point, and if the next actual position point exceeds the boundary of the display area, the cursor is moved to the boundary of the display area according to the direction of the displacement vector.
And if the next actual position point does not exceed the boundary of the display area, controlling the cursor to move to the next actual position point according to the direction of the displacement vector.
In practical application, the displacement vector in the current sampling period is obtained according to an application programming interface (Application Programming Interface, API) of the system.
In this embodiment of the present application, taking the API as an example, the API is a call interface reserved for an application program by an operating system, the application program calls the API of the operating system to enable the operating system to execute a command of the application program, and under the condition that a cursor movement signal is received inside the system, the API of the system obtains a displacement vector in a current sampling period.
When a user performs cursor control, the displacement vector generated by cursor movement in the current sampling period can be conveniently and rapidly acquired when the displacement vector in the sampling period is acquired according to the API of the operating system.
According to the cursor control method provided by the embodiment, the cursor reference point is preset in the system, the current simulation position point of the cursor is obtained based on the timing of the cursor reference point, after the position information of the current simulation position point of the cursor and the cursor reference point is determined, the visual field rotation angle is rotated by calculating the distance vectors of the two points, after the cursor reaches the boundary of the area, in order to obtain the displacement vector generated by the cursor moving signal, and after each calculation is completed, the current simulation position point of the cursor is reset to the cursor reference point. When the user moves the cursor, the user drags the cursor in the original direction to be regarded as effective operation, and the cursor is continuously presented according to the original visual field rotation effect, so that the user experience is improved.
