Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application provides a method and a device for controlling spherical motion, a storage medium and computer equipment.
Referring to fig. 1, fig. 1 is a schematic view of a scene of a control system of a sphere motion provided in an embodiment of the present application, where the control system of the sphere motion may include any one of the control devices of the sphere motion provided in the embodiment of the present application, and the control device of the sphere motion may be specifically integrated in a terminal or a server, and the terminal may be a smart phone, a tablet Computer, an intelligent bluetooth device, a notebook Computer, or a Personal Computer (PC), and the server may be a single server or a server cluster including a plurality of servers.
Taking a computer device as an example, the terminal can receive trigger operation information when the virtual sphere starts to move; determining a speed weight value of the virtual sphere according to the trigger operation information; determining the motion parameters of the virtual sphere in the motion process according to the speed weight value; and controlling the movement of the virtual sphere according to the movement parameters.
The terminal can be a device for running a game, and the game can be a virtual ball game such as a virtual football game, a virtual ice hockey game, a virtual hockey game or a virtual billiards game. The velocity weight value can be used for representing the ratio of the rotating speed to the linear velocity when the virtual sphere starts to move. Different virtual ball games may have different ways for a player to trigger a virtual ball to start moving, and different trigger operation information in the same virtual ball game may correspond to different speed weight values, where the trigger operation information may include ball hitting manners (e.g., a high-stick ball hitting manner and a flat-stick ball hitting manner in a virtual billiards game) and/or ball hitting positions that may affect the size of the speed weight values. The motion parameters may include a velocity parameter and an acceleration parameter at any time between the start of the movement and the stop of the movement of the virtual sphere.
For example, as shown in fig. 1, in a game interface of a virtual ball game, when a player directly triggers a virtual ball 1 in the game interface to start moving through a touch screen or indirectly triggers the virtual ball 1 in the game interface to start moving through a touch screen by manipulating a virtual club 2 in the game interface, the terminal may receive trigger operation information when the player triggers the virtual ball 1 to start moving, that is, position information and manner information of a hitting point 3 selected when the player triggers the virtual ball 1 to start moving, and determine a corresponding speed weight value according to the received position information and manner information of the hitting point 3, for example, when the position of the hitting point 3 is a middle position of the virtual ball 1 and the manner of hitting is a manner of hitting 1 (e.g., a high-stick manner), the corresponding speed weight value may be equal to 0.5, so as to represent that a rotating speed and a linear speed of the virtual ball 1 at the start of moving are the same direction and a large rotating speed of the virtual ball 1 The small value is half of the linear velocity, then the motion parameters, namely, the velocity parameter and the acceleration parameter, of the virtual sphere 1 in the motion process can be determined according to the velocity weight value, and the virtual sphere 1 is controlled to move on the virtual plane 4 by the velocity parameter and the acceleration parameter, so that the simulation of the sphere motion is realized.
As shown in fig. 2, fig. 2 is a schematic flow chart of a control method of a sphere motion provided in an embodiment of the present application, and a specific flow of the control method of the sphere motion may be as follows:
s101, receiving trigger operation information when the virtual sphere starts to move.
In the present embodiment, the control method of the ball motion can be applied, but not limited to, different virtual ball game applications, for example, a virtual football game, a virtual ice hockey game, a virtual billiards game, and the like.
Wherein, in different virtual ball games, a player can trigger a virtual ball to start moving, and the manner of triggering the virtual ball to start moving by the player may be different, for example, in a virtual football game, the player can directly trigger the virtual ball in the game interface to start moving by a touch screen manner, and in a virtual billiards game, the player can indirectly trigger the virtual ball in the game interface to start moving by manipulating a virtual ball rod in the game interface by a touch screen manner. The trigger operation information may include a hitting mode (for example, a high-backswing mode or a flat-backswing mode in a virtual billiard game, or a big-backswing mode or a kick-out mode in a virtual football game) selected by a player when the virtual ball starts to move, and/or a hitting point position (that is, a contact point position of a finger of the player or a virtual ball and the virtual ball) and/or the like, which may affect the magnitude of the ratio between the rotational speed and the linear speed when the virtual ball starts to move.
In specific implementation, as shown in fig. 3, a game interface of a virtual ball game may include a plurality of ball hitting mode function keys corresponding to a plurality of ball hitting modes, for example, a ball hitting mode 1 function key, a ball hitting mode 2 function key, a ball hitting mode 3 function key, and a ball hitting mode 4 function key, and when a player triggers a virtual ball 1 in the game interface to start moving, the player may select a corresponding ball hitting mode by clicking the ball hitting mode function key, and may adjust a position of a contact point 3 between a virtual ball 2 and the virtual ball 1 by dragging on a touch screen to select a position of a ball hitting point of a heart instrument, so as to control subsequent movement of the virtual ball 1 on a virtual plane 4 by the selected ball hitting mode and the position of the ball hitting point.
And S102, determining the speed weight value of the virtual sphere according to the trigger operation information.
In the same virtual ball game, different trigger operation information can correspond to different speed weight values. In addition, in specific implementation, the trigger operation information may be matched with the speed weight value to establish a corresponding relationship between the trigger operation information and the speed weight value, and the terminal may query to obtain the corresponding speed weight value based on the corresponding relationship when receiving the trigger operation information.
In this embodiment, the speed weight value may be used to represent a ratio between a rotation speed and a linear speed when the ball starts to move, and the speed weight value is only related to the trigger operation information when the player triggers the virtual ball to start moving, that is, only related to the ball hitting operation of the player, and is not related to the linear speed when the virtual ball starts to move. Therefore, when the movement of the ball body is simulated, the speed weight value is introduced, so that the movement of the virtual ball body is controlled by one more dimension in the game, different influences of different batting operations of a player on the subsequent movement of the virtual ball body can be reflected, and the subsequent sense of reality of the ball body movement simulation is further enhanced.
Specifically, different hitting operations for the above players can be distinguished by changing the magnitude of the velocity weight value. In one embodiment, when it is predefined that the rotation speed at the time of starting the movement of the virtual sphere is not greater than the linear velocity, the value range of the velocity weight value may be [ -1, 1], where if the velocity weight value is a negative value, it indicates that the rotation speed and the linear velocity direction at the time of starting the movement of the virtual sphere are opposite, if the velocity weight value is a positive value, it indicates that the rotation speed and the linear velocity direction at the time of starting the movement of the virtual sphere are the same, further, if the velocity weight value is 1, it indicates that the rotation speed and the linear velocity direction at the time of starting the movement of the virtual sphere are the same and equal, and if the velocity weight value is 0, it indicates that the rotation speed at the time of starting the movement of the virtual sphere is 0. In some alternative embodiments, when it is not limited that the rotation speed at which the virtual sphere starts to move is not greater than the linear speed, the boundary value of the range of the velocity weight value may also be a value having an absolute value greater than 1, for example, may be [ -5, 5 ].
In this embodiment, the direction of the rotation speed may be a rolling direction when the virtual sphere performs a rolling motion at the rotation speed, and the ratio between the rotation speed and the linear velocity may be calculated after converting the units of the rotation speed and the linear velocity into the same, where the conversion relationship is v ═ 2 pi nr, where v is the linear velocity, n is the rotation speed, and r is the radius. Further, in order to reduce the subsequent operation amount for simulating the ball movement, the direction of the rotation speed during the virtual ball movement may be predefined as the same as or opposite to the direction of the linear velocity, that is, if the direction of the linear velocity during the virtual ball movement is forward, the direction of the rotation speed during the virtual ball movement may only be forward or backward, but not be other directions such as left or right. Therefore, the rotation speed in the virtual sphere movement process is concerned, and the direction of the rotation speed is simplified, so that the accuracy of subsequent simulation of the sphere movement can be met, and the calculation amount can be reduced.
S103, determining the motion parameters of the virtual sphere in the motion process according to the speed weight value.
As shown in fig. 4, the motion parameters may specifically include a speed parameter and an acceleration parameter, and the S103 may specifically include:
and S1031, determining at least one motion mode of the virtual sphere in the motion process according to the speed weight value.
Specifically, the movement modes involved from the start movement to the complete stop movement of the virtual sphere at most can include three movement modes of bouncing in the air, sliding and rolling on a virtual plane and pure rolling, and during the movement of the real sphere, the bouncing movement of the real sphere in the air occurs before the sliding and rolling movement on the virtual plane, and the sliding and rolling movement on the virtual plane occurs before the pure rolling movement on the virtual plane.
In this embodiment, in order to reduce the subsequent computation amount for simulating the ball motion, it may be considered that the virtual ball is only subjected to the gravity action when performing the bouncing motion in the air, and the linear velocity component in the height direction is attenuated according to a preset proportion each time the virtual ball touches the ground (i.e., contacts the virtual plane), and is zeroed when the linear velocity component in the height direction is smaller than a preset threshold, and then the virtual ball is considered to subsequently only move on the virtual plane. Furthermore, it can be understood that the rotation speed and the linear velocity component in the horizontal direction of the virtual sphere are not affected when the virtual sphere performs bouncing movement in the air, and at least one movement mode of the virtual sphere during movement can be understood as a movement mode involved in the movement of the virtual sphere from the start to the complete stop of the movement.
In a specific embodiment, the S1031 may specifically include:
and S1-1, when the speed weight value is a preset value, determining that the movement mode of the virtual sphere in the movement process comprises pure rolling.
For example, the preset value may be 1, that is, when the ratio of the rotation speed to the linear speed when the virtual sphere starts to move is 1, the terminal may determine that the movement manner of the virtual sphere during the movement process includes pure rolling, and accordingly, the virtual sphere only performs rolling movement on a virtual plane subsequently.
And S1-2, when the speed weight value is not a preset value, determining the movement modes of the virtual sphere in the movement process, including sliding and rolling, and pure rolling.
In the above example, when the rate weight value is not equal to 1, that is, the rotation speed and the linear speed of the virtual sphere when the virtual sphere starts to move are different in at least one of magnitude and direction, the terminal may determine that the movement modes of the virtual sphere during the movement include sliding and rolling, and pure rolling, and accordingly, the virtual sphere may subsequently perform sliding movement and rolling movement simultaneously on the virtual plane, and then perform only rolling movement on the virtual plane.
S1032, determining an initial speed parameter of the virtual sphere.
In an embodiment, as shown in fig. 5, when the movement mode of the virtual sphere during the movement includes sliding and rolling, and pure rolling, the initial speed parameter may include an initial sliding linear speed parameter, an initial rotation speed parameter, and an initial rolling linear speed parameter, and the S1032 may specifically include:
s11, obtaining initial sliding linear speed parameters of the virtual sphere.
Specifically, with reference to fig. 3, a hitting power control bar may be further included in the game interface of the virtual ball game, and when the player triggers the virtual ball in the game interface to start moving, the player may drag the hitting power control bar through the touch screen to adjust a hitting power, so as to control a subsequent movement of the virtual ball through the selected hitting power.
Accordingly, the S11 may specifically include: the method comprises the steps of receiving batting strength information when a player triggers a virtual ball to start moving, and determining a corresponding initial sliding linear velocity parameter according to the batting strength information, wherein the larger the batting strength selected by the player when the player triggers the virtual ball in a game interface to start moving is, the larger the initial sliding linear velocity corresponding to the virtual ball is.
In some alternative embodiments, the S11 may specifically include:
s2-1-1, receiving the input motion trajectory line through the game interface.
Specifically, as shown in fig. 6, when the player triggers the virtual sphere 1 in the game interface to start moving, the motion trajectory Line of the virtual sphere 1 may also be drawn on the game interface through a touch screen manner, so that the virtual sphere 1 may subsequently move along the motion trajectory Line.
S2-1-2, determining the movement displacement of the virtual sphere based on the movement trajectory line.
Specifically, the movement displacement of the virtual sphere may be equal to the length of the movement trajectory line, and the movement trajectory line may be a straight line segment.
And S2-1-2, determining an initial sliding linear velocity parameter of the virtual sphere according to the velocity weight value, the motion displacement and the preset motion duration.
In particular, the terminal can be obtained by solving the equation Ax2And + Bx + C is 0 to obtain the initial sliding linear velocity parameter of the virtual sphere, wherein:
A＝[(1-k)2*(a1-a2)]/(2*a12)；
B＝[a1*T*k+a2*T*(1-k)]/a1；
C＝-0.5*a2*T2-L；
k＝Vpc+Sr-Vpc*Sr；
wherein Sr is a velocity weight value, L is a motion displacement, T is a motion duration, Vpc is a preset critical velocity ratio value, a1 is a preset sliding acceleration parameter, a2 is a preset rolling acceleration parameter, and a positive solution obtained by solving the equation is an initial sliding linear velocity parameter of the virtual sphere.
And S12, determining an initial rotation speed parameter of the virtual sphere according to the initial sliding linear speed parameter and the speed weight value.
Specifically, the speed weight value is used to represent a ratio between a rotation speed and a linear speed when the virtual sphere starts to move, and accordingly, the initial rotation speed parameter may be a product of the initial sliding linear speed parameter and the speed weight value.
And S13, determining an initial rolling linear velocity parameter of the virtual sphere according to the initial sliding linear velocity parameter, the velocity weight value and a preset critical velocity proportion value.
In this embodiment, the initial sliding linear velocity parameter is used to represent a linear velocity when the virtual sphere starts to slide and roll on a virtual plane, the initial rotation speed parameter is used to represent a rotation speed when the virtual sphere starts to slide and roll on the virtual plane, and the initial rolling linear velocity parameter is used to represent a linear velocity when the virtual sphere starts to perform pure rolling on the virtual plane. The critical speed ratio value (e.g., 0.45) is used to determine a linear speed boundary value of the two motion modes, i.e., sliding and rolling and pure rolling, and can be obtained by optimizing a motion simulation effect through experiments performed by research and development personnel.
In specific implementation, the terminal may calculate the initial sliding linear velocity parameter of the virtual sphere through a preset calculation formula 1, where the calculation formula 1 may be as follows:
v1＝(Vpc+Sr-Vpc*Sr)*v0；
wherein v1 is the initial rolling linear velocity parameter, Vpc is the critical velocity ratio value, Sr is the velocity weight value, and v0 is the initial sliding linear velocity parameter.
S1033, determining a speed parameter and an acceleration parameter corresponding to each motion mode according to the initial speed parameter.
Specifically, with continued reference to fig. 5, the above S1033 may specifically include:
s14, determining a first acceleration parameter corresponding to sliding and rolling according to the initial rolling linear speed parameter, the initial rotating speed parameter, the initial sliding linear speed parameter and a preset sliding acceleration parameter.
The terminal may calculate the first acceleration parameter by using a calculation formula 2, where the calculation formula 2 may be as follows:
a3＝(v2-v1)/(v0-v1)*a1；

Specifically, with reference to fig. 3, a hitting power control bar may be further included in the game interface of the virtual ball game, and when the player triggers the virtual ball in the game interface to start moving, the player may drag the hitting power control bar through the touch screen to adjust a hitting power, so as to control a subsequent movement of the virtual ball through the selected hitting power. Accordingly, the S21 may specifically include: the method comprises the steps of receiving batting strength information when a player triggers a virtual ball to start moving, and determining a corresponding initial rolling linear velocity parameter according to the batting strength information, wherein the larger the batting strength selected by the player when the player triggers the virtual ball in a game interface to start moving is, the larger the initial rolling linear velocity corresponding to the virtual ball is.

And S104, controlling the movement of the virtual sphere according to the movement parameters.
Although the real world ball is simultaneously subjected to the sliding friction force and the rolling friction force when sliding and rolling, in the embodiment, in order to reduce the amount of operation for simulating the virtual ball motion, since the sliding friction force is large, only the influence of the sliding friction force on the sliding linear velocity of the virtual ball motion is considered in the sliding and rolling process of the virtual ball.
Specifically, the preset sliding acceleration parameter may be understood as an acceleration generated by a sliding friction force acting on the virtual sphere, and when the virtual sphere slides and rolls, if the sliding linear velocity of the virtual sphere is greater than the rotation speed, the sliding linear velocity of the virtual sphere is affected by the sliding friction force and is reduced by the sliding acceleration parameter, and the rotation speed is increased by the first acceleration parameter in the direction of the sliding linear velocity, and if the sliding linear velocity of the virtual sphere is smaller than the rotation speed, the sliding linear velocity of the virtual sphere is affected by the sliding friction force and is increased by the sliding acceleration parameter, and the rotation speed is reduced by the first acceleration parameter in the direction of the sliding linear velocity.
Then, when the sliding linear velocity and the rotating speed of the virtual sphere are equal in magnitude and same in direction, the movement mode of the virtual sphere is switched from sliding and rolling to pure rolling, and when the virtual sphere performs pure rolling movement, the rolling linear velocity and the rotating speed in the movement process of the virtual sphere are the same at all times and are influenced by rolling friction force to be reduced together by a preset rolling acceleration parameter, wherein the rolling acceleration parameter can be understood as acceleration generated by the rolling friction force acting on the virtual sphere.
In the present embodiment, the rolling acceleration parameter and the sliding acceleration parameter are fixed values, for example, may be 7m/s respectively2And 1.5m/s2The first acceleration parameter is not related to the hitting operation of the player, and can be determined by referring to the sliding friction force and the rolling friction force which are applied to the ball in the real world when the ball performs the sliding motion and the rolling motion.
In this way, since the friction does not need to be completely simulated, the computation amount is greatly reduced, so that the method for controlling the sphere motion in the above embodiment can be applied to the mobile terminal. Meanwhile, although the calculation method is simplified, the motion and the rotation of the virtual sphere are integrally in accordance with the physical law and the operation of the player, so that the entertainment of the game and the immersion of the player can be ensured.
In an embodiment, with continuing reference to fig. 5, when the movement manner of the virtual sphere during the movement process includes sliding and rolling, and pure rolling, the initial speed parameter may specifically include an initial sliding linear speed parameter, an initial rotation speed parameter, and an initial rolling linear speed parameter, and the S104 may specifically include:
and S17, controlling the virtual sphere to slide and roll by using the first speed parameter and the first acceleration parameter.
Specifically, the first speed parameter may include a sliding linear speed parameter and a first rotation speed parameter, and the S17 may specifically include: and controlling the virtual sphere to perform sliding motion by using the sliding linear velocity parameter and the sliding acceleration parameter, and controlling the virtual sphere to perform rolling motion by using the first rotation speed parameter and the first acceleration parameter, so that the simulation of sliding and rolling motion of the virtual sphere is realized.
And S18, in the sliding and rolling movement process, when the sliding linear speed of the virtual sphere is equal to the initial rolling linear speed parameter, controlling the virtual sphere to perform pure rolling movement according to a second speed parameter and a second acceleration parameter.
Specifically, during the sliding and rolling motion, when the sliding linear velocity parameter and the first rotational velocity parameter of the virtual sphere are equal in size and same in direction, the terminal may switch the motion mode of the virtual sphere from sliding and rolling to pure rolling, and when the virtual sphere performs pure rolling motion, the first rolling linear velocity parameter and the second rotational velocity parameter of the virtual sphere during the pure rolling motion may be always the same and decrease with the second acceleration parameter.
For example, if the initial sliding linear velocity parameter V0 is 10m/s, the velocity weight Sr is 0.4, and the calculated initial rolling linear velocity V1 is 6.7m/s, a schematic diagram of the linear velocity (including the sliding linear velocity in the sliding and rolling motion phase and the rolling linear velocity in the pure rolling motion phase) and the change of the rotational velocity with the motion duration t of the virtual sphere in the two motion phases of sliding and rolling and pure rolling may be as shown in fig. 7, where a short dashed line represents the linear velocity change curve, a long dashed line represents the rotational velocity change curve, and in the sliding and rolling motion phase (0 to t1), the sliding linear velocity of the virtual sphere gradually decreases and the rotational velocity gradually increases, and when the two are equal, the virtual sphere enters the pure rolling motion phase (t1 to t2), and the changes of the two are kept consistent.
In another embodiment, when the movement mode of the virtual sphere in the movement process includes pure scrolling, the initial speed parameter may specifically include an initial scrolling linear speed parameter, and the S104 may further include:
and S23, controlling the virtual sphere to perform pure rolling motion according to the third speed parameter and the third acceleration parameter.
The third speed parameter may specifically include a second rolling linear speed parameter and a third rotation speed parameter, and specifically, in the pure rolling motion process, the second rolling linear speed parameter and the third rotation speed parameter of the virtual sphere are always the same and are reduced by the third acceleration parameter.
For example, if the weight value Sr is 1.0, and the initial rolling linear velocity parameter V1 and the initial rotation speed V2 are both 10m/s, a schematic diagram of the linear velocity (i.e., the rolling linear velocity) and the rotation speed of the virtual sphere changing with the movement time length t may be as shown in fig. 8, where a short dotted line represents a linear velocity change curve, a long dotted line represents a rotation speed change curve, and when both of the entire movement stages (0 to t3) of the virtual sphere are always overlapped, it indicates that the virtual sphere only performs the pure rolling movement.
In the above embodiment, the above S12 and S13 may be performed synchronously, and there is no sequence therebetween, and similarly, the above S14 and S15 and the above S16 may also be performed simultaneously, that is, the above S16 may be performed simultaneously during the execution of S14 and S15.
