[0002] A virtual joystick is a tool that simulates the functions of a traditional game controller or physical joystick. It usually uses the 2D coordinates of the screen touch to map the virtual scene's 3D coordinate system in real time, and uses the touch screen to control objects in the virtual scene. A virtual joystick generally consists of a circular area with a control point. Users can touch and move this point to control the direction or position of the target object. At present, compared with a physical joystick, the operation of a virtual joystick is more likely to produce jumpy changes. For example, when using a virtual joystick to adjust the direction, it is easy to have irregular jumping problems in the steering range, which affects the user's operating experience.

During the rotation process, the rotation completion ratio of the target object is determined according to the current direction of the target object and the rotation angle difference.

[0055] Figure 1is an optional flow chart of the object control method based on the virtual joystick provided in the embodiment of the present application. Figure 1 The method may include but is not limited to steps S101 to S106.

[0056] Step S101, obtaining the target coordinate point of the virtual joystick;

[0057] Step S102, determining the target direction according to the center coordinate point of the virtual joystick and the target coordinate point;

[0058] Step S103, determining a rotation angle difference according to the starting direction and the target direction;

[0059] Step S104, controlling the target object to rotate from the starting direction toward the target direction, and obtaining the current direction of the target object;

[0060] Step S105, determining a rotation completion ratio of the target object according to the current direction of the target object and the rotation angle difference;

[0061] Step S106: When the rotation completion ratio is greater than the expected completion ratio, the target object is controlled to rotate from the current direction toward the target direction at a reduced speed.

[0062] In step S101 of some embodiments, please refer to Figure 2 ,A virtual joystick is generally composed of a circular area with a control point in the middle of the circular area. The circular area is called a disc, and the control point is equivalent to a joystick. To operate the virtual joystick, the operator can click a certain position on the disc or drag from the control point in the middle to a certain position on the disc, which can simulate the actual operation of moving the joystick to the corresponding position. In a rotation operation, the target coordinate point can be determined based on the position where the operator touches the disc.

[0063] In step S102 of some embodiments, the center coordinate point of the virtual joystick refers to the midpoint of the disk, that is, the position of the control point. In this embodiment, the disk can be used as a coordinate system, and the default center coordinate point is (0, 0). After obtaining the target coordinate point input by the operator, the target direction can be determined according to the center coordinate point and the target coordinate point, that is, the target direction is the direction from the center coordinate point to the target coordinate point.

[0064] In step S103 of some embodiments, the target object of this embodiment may refer to a virtual character, a scene perspective, a character skill, or an indicator, etc. The indicator is a visual feedback tool for the result of the virtual joystick operation. The style of the indicator is usually designed as a dot / circle / arrow, etc., and the position and direction are marked by graphic feedback to help the operator understand complex operations. This embodiment can realize virtual task steering, scene perspective rotation adjustment, skill rotation, and indicator rotation, etc. through a virtual joystick. In a rotation operation, the starting direction may be the direction at the end of the last rotation operation, that is, for the target object of the virtual character or scene perspective, the starting direction is the direction before the current operation starts. In a rotation operation, the starting direction may also be the direction specified by the operator in the rotation operation, that is, for the target object of the skill or skill indicator, in a rotation operation, the operator slides from the starting coordinate point to the target coordinate point on the disk of the virtual joystick, and the direction corresponding to the starting coordinate point is the starting direction of the indicator. The absolute value of the angle of the starting direction is subtracted from the angle of the target direction to obtain the rotation angle difference.

[0065] In steps S104 to S106 of some embodiments, after determining the target direction, the target object is controlled to start rotating from the starting direction toward the target direction, and during the rotation of the target object, the real-time rotation completion ratio of the target object is determined according to the real-time current direction of the target object and the rotation angle difference, and at the same time, it is determined whether the rotation completion ratio is greater than the expected completion ratio. When the rotation completion ratio is greater than the expected completion ratio (for example, 20%), the target object is controlled to rotate from the current direction toward the target direction at a reduced speed. This embodiment controls the rotation process of the target object in stages based on the rotation completion ratio. In the second half of the rotation, the target object is controlled to rotate at a reduced speed, which can prevent the target object from directly changing in a jumpy manner and achieve the visual effect of smooth steering of the virtual joystick.

[0066] In some embodiments, before step S101, the object control method based on the virtual joystick of the embodiment of the present application may also include but is not limited to the following steps:

[0067] Step S201, obtaining a starting coordinate point;

[0068] Step S202, determining a starting direction according to the center coordinate point and the starting coordinate point of the virtual joystick.

[0069] In this embodiment, the target object is an indicator of auxiliary skill release in the game as an example, please refer to Figure 3In a steering operation, the operator slides from the starting coordinate point 301 (x0, y0) to the target coordinate point 303 (x, y) on the disk of the virtual joystick. In response to the operator's steering operation, the processor determines the starting direction according to the center coordinate point 302 (0, 0) of the virtual joystick and the starting coordinate point (i.e., the starting touch coordinate point), i.e., the direction in which the center coordinate point points to the starting coordinate point, and determines the target direction according to the center coordinate point of the virtual joystick and the target coordinate point (i.e., the current touch coordinate point). The starting direction is the starting direction of the skill on the indicator, and the target direction is the release direction of the skill on the indicator.

[0070] In some embodiments, the step of controlling the target object to rotate from the starting direction toward the target direction in step S104 may include, but is not limited to, steps S301 to S304:

[0071] Step S301, determining a first distance according to the target coordinate point and the center coordinate point;

[0072] Step S302, determining an operation sensitivity according to the first distance, wherein the operation sensitivity is proportional to the first distance;

[0073] Step S303, determining a first rotation speed according to the operation sensitivity and the basic rotation speed;

[0074] Step S304: Control the target object to rotate uniformly at the first rotation speed from the starting direction toward the target direction.

[0075] In this embodiment, considering the nonlinear angle change caused by the touch and swipe of the virtual joystick, within the range of the joystick's disc, the closer to the center of the circle, the greater the angle difference caused by a slight swipe, and the more difficult it is to control the accuracy of the touch point. When using the virtual joystick to adjust the direction, the problem of irregular steering amplitude jumps is prone to occur. This embodiment determines a first distance based on the target coordinate point and the center coordinate point. The first distance represents the operator's operating range on the disc. The operation sensitivity can be calculated in combination with the first distance. This embodiment defines the operation sensitivity as proportional to the first distance, that is, the sensitivity of the virtual joystick's disc center can be defined as 0, and the maximum edge is defined as 1. The operation sensitivity of the entire touch area is mapped in the interval [0, 1]. The operation sensitivity can change linearly according to the distance between the touch point (i.e., the target coordinate point) and the center of the disc (i.e., the center coordinate point), so that the closer to the coordinate center point, the lower the operation sensitivity, and vice versa.

[0076] In one example, the operational sensitivity can be calculated according to the following formula:

[0077] Sensitivity=(x 2 +y 2 ) / R 2 ;

[0078] Among them, Sensitivity represents the operation sensitivity, with a value range of 0 to 1, (x, y) represents the target coordinate point, R represents the radius of the disk, (x 2 +y 2 ) represents the square of the first distance.

[0079] In another example, the operation sensitivity may also be a ratio of the first distance to the radius of the disk.

[0080] The first rotation speed is determined according to the operation sensitivity and the basic rotation speed, and specifically, the first rotation speed can be obtained by multiplying the operation sensitivity by the basic rotation speed. In the first rotation stage of the target object (i.e., the stage where the rotation completion ratio is less than the expected completion ratio), the first rotation speed is used for uniform rotation, so that when the operator operates close to the center of the disc, the target object rotates at a lower speed, reducing the situation where the short-term steering amplitude is too large, making the operator's control more precise and the indicator performance more stable.

[0081] In some embodiments, the basic rotation speed may be obtained by, but not limited to, steps S401 to S402:

[0082] Step S401, obtaining the expected rotation time;

[0083] Step S402: Divide the rotation angle difference by the expected rotation time to obtain a basic rotation speed.

[0084] In this embodiment, the basic angular velocity is positively correlated with the rotation angle. The larger the rotation angle, the higher the basic velocity. The basic rotation velocity is calculated by dividing the rotation angle difference by the expected rotation time (for example, 0.15 seconds), so that the subsequent rotation process can be performed based on the basic rotation velocity. Regardless of the size of the required rotation angle difference, it can be completed within a certain range of the expected rotation time.

[0085] In some embodiments, step S105 may include but is not limited to steps S501 to S502:

[0086] Step S501, determining a current angle difference according to a current direction and a target direction;

[0087] Step S502: determining the rotation completion ratio of the target object according to the current angle difference and the rotation angle difference.

[0088] In this embodiment, please continue to refer to Figure 3, subtract the angle corresponding to the target direction from the angle corresponding to the current direction of the target object to get the current angle difference. The rotation completion ratio of the target object is determined based on the current angle difference and the rotation angle difference of the entire rotation process. The rotation completion ratio can be calculated using the following formula:

[0089] ratio = 1-delta / angle;

[0090] Among them, ratio represents the rotation completion ratio, delta represents the current angle difference, and angle represents the rotation angle difference.

[0091] In another example, the completed angle difference may be determined according to the current direction and the target direction, and the completed angle difference may be divided by the rotation angle difference of the entire rotation process to obtain the rotation completion ratio.

[0092] In some embodiments, controlling the target object to rotate from the current direction toward the target direction at a reduced speed in step S106 may include, but is not limited to, steps S601 to S603:

[0093] Step S601, determining a rotation completion inverse ratio according to the rotation completion ratio;

[0094] Step S602, determining a second rotation speed according to the rotation completion inverse ratio, the basic rotation speed and the operation sensitivity;

[0095] Step S603: Control the target object to rotate at a second rotation speed from the current direction toward the target direction.

[0096] In this embodiment, the rotation completion inverse ratio represents the proportion of the current unfinished partial angle of the target object. The second rotation speed is determined according to the rotation completion inverse ratio, the basic rotation speed and the operation sensitivity. Specifically, the second rotation speed can be obtained by multiplying the rotation completion inverse ratio, the operation sensitivity and the basic rotation speed. In the second rotation stage of the target object (i.e., the rotation completion ratio is greater than the expected completion ratio stage), since the rotation completion inverse ratio is reduced in real time, the second rotation speed is used in this stage to achieve the decelerated rotation of the target object. In this embodiment, the target object is rotated according to the dynamic speed curve through the rotation completion inverse ratio, the real-time coordinate change is converted into a smooth change process, the target object angle jump is reduced, and the operation sensitivity is dynamically adjusted, so as to achieve the effect of high control accuracy, more stable indicator performance or more stable character steering.

[0097] In some embodiments, the object control method based on the virtual joystick of the embodiment of the present application may also include but is not limited to steps S701 to S702:

[0098] Step S701, calculating a second distance between the starting coordinate point and the center coordinate point;

[0099] Step S702: When the second distance is less than the blind spot radius, the target object is locked, wherein the blind spot radius is determined based on the radius of the disk where the virtual joystick is located.

[0100] In this embodiment, considering that the virtual joystick contact point has poor stability, when the touch point is pressed and not moved, the unconscious movement of the finger will cause slight changes in the joystick; or when the finger is not dragged obviously, it will cause the indicator to shake, affecting the user experience. This embodiment can set a touch anti-shake mechanism, please refer to Figure 4 , a smaller circular blind spot is set at the center of the disk (the radius of the blind spot can be 20% of the radius of the disk), and no response is given to operations within the blind spot, and normal operation can be performed after leaving the blind spot. That is, in a rotation operation, when the distance between the starting coordinate point and the center coordinate point is less than the blind spot radius, it means that the starting touch point is in the blind spot, and it is considered that the operator has no intention of operation after pressing the joystick, and a certain distance may be caused by the operator's finger shaking. The system locks the target object, thereby reducing the situation where the target object shakes unexpectedly. In this embodiment, for the indicator, locking the target object means not activating the indicator. When the distance between the starting coordinate point and the center coordinate point generated by movement after the operator presses the joystick position is greater than the blind spot radius, the indicator is activated again at this time, and normal operation can be performed after leaving the blind spot.

[0101] In some embodiments, a certain time (such as 200 milliseconds) can be set as the touch activation time, and the operation within the activation time is defined as a click, and the operation outside the time is defined as a long press, thereby realizing diversified operations of the same set of components.

[0102] In some embodiments, please refer to Figure 5 , this embodiment takes into account that different size ratios of the joystick and the disc will affect the operator's operating speed. For example, to achieve the same rotation effect, the smaller the size ratio of the joystick and the disc, the greater the psychological expected distance given to the operator, requiring a larger swiping range and faster finger operation speed, and the change process is relatively slow; the size ratio of the joystick and the disc is moderate, and a balance can be achieved between the swiping range and the change speed; the size ratio of the joystick and the disc is too large, requiring a smaller swiping range and a faster change process. Based on this, in order to achieve a balance between the swiping range and the change speed, this embodiment can adjust the size ratio of the joystick and the disc, and it can be determined through test tuning that the size ratio of the joystick and the disc can be 35:100.

[0103] According to some embodiments of the present application, the embodiments of the present application have the following beneficial effects:

[0104] This embodiment controls the rotation process of the target object in stages based on the rotation completion ratio. In the second half of the rotation, the target object is controlled to slow down its rotation, which can prevent the target object from making direct jump changes and achieve the visual effect of smooth steering of the virtual joystick.

[0105] The operation sensitivity on the disc of this embodiment is proportional to the user's operation distance relative to the center of the disc. The closer to the center of the disc, the lower the operation sensitivity. This allows the user to accurately control the angle difference when operating in the area near the disc, thereby achieving precise steering control.

[0106] In this embodiment, the basic angular velocity is positively correlated with the rotation angle. The larger the rotation angle, the higher the basic velocity. The basic rotation velocity is calculated by dividing the rotation angle difference by the expected rotation time, so that the subsequent rotation process can be performed on the basis of the basic rotation velocity. Regardless of the size of the required rotation angle difference, it can be completed within a certain range of the expected rotation time.

[0107] In the deceleration stage, this embodiment realizes the rotation of the target object according to the dynamic speed curve by completing the inverse ratio through rotation, converts the real-time coordinate change into a smooth change process, reduces the angle jump of the target object, and dynamically adjusts the operation sensitivity, thereby achieving high control accuracy, more stable indicator performance or more stable character turning effect.

[0108] This embodiment sets a touch blind zone for starting operation. When the user stays at the center of the joystick and the finger makes an unconscious movement, the indicator is not activated because the movement is within the touch blind zone, which can reduce the user's misoperation.

[0109] The embodiment of the present application also provides an object control system based on a virtual joystick, comprising:
