20250186888
The application relates to the technical field of game design, and in particular to methods and systems for controlling movement of virtual object, electronic devices, computer-readable storage medium, and computer program products.
During a game, a virtual object may be in a first state before moving, and may be in a second state when moving. For example, in a strategy game, the virtual object hovers around a certain position when it stops moving, and enters a moving state from a hovering state after receiving a movement instruction. However, when the virtual object enters the moving state from the hovering state, changes of angle may cause the problem of stiff trajectory transition and stiff speed transition. When a large number of virtual objects enter moving states from hovering states at the same time, sending movement parameters of the virtual objects relying on a server will cause an excessive computing burden of the server. Therefore, it is necessary to provide a method for controlling movement of virtual object, which can make full use of performance of a client to reduce the computing burden of the server and support a smooth transition of moving states and a smooth transition of moving processes of the virtual object.
The purpose of this application is to provide methods for controlling movement of virtual object, electronic devices, computer-readable storage medium, and computer program products, which may make full use of performance of a client to reduce computing burden of a server and may support a smooth movement of the virtual object, thereby more realistically restoring a posture of the virtual object in a real scene.

Compared with the prior art, the embodiments of the present application have differences and effects as follows.
According to the method for controlling movement of virtual object in the embodiments of the present application, for the movement instruction instructing to move the first virtual object hovering around the first position to the second position, on the one hand, the execution result of the movement instruction on the server may be simplified as moving the second virtual object directly from the first position to the second position without considering the state switching of the first virtual object and the trajectory transition and speed transition processes caused thereby, thus greatly reducing the computing burden of the server, and greatly reducing the communication data between the server and the client. On the other hand, the execution result of the movement instruction on the client may be understood as controlling the first virtual object to move towards the second virtual object (or may be understood as controlling the first virtual object to chase the second virtual object), and ensuring that the trajectory transition process and the speed transition process are as smooth as possible during the movement.
In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the solutions of the embodiments of the present application will be further described in detail hereinafter with reference to the accompanying drawings. Obviously, the described embodiments are part of but not all the embodiments of the present application. Based on the described embodiments of the present application, all other embodiments obtained by ordinary skilled in the art without creative work are within the protection scope of the present application.
In a determining step S101, the client 20 determines relative orientation parameters between a first virtual object and a second virtual object based on a second position-parameter and a second movement parameter. The relative orientation parameters include an instantaneous distance and an instantaneous angle-difference between the first virtual object and the second virtual object, and the second movement parameter includes a second instantaneous speed of the second virtual object.
The first virtual object may refer to a controllable object in a game program executed on the client 20, and include a virtual character, and a virtual prop, etc. For example, for a single fighter or a fighter formation operated in a unified manner in a war game, the fighter or the fighter formation may be selected as the first virtual object through an input device of the client electronic device (also referred to as “the client” 20 in this application), such as a touch screen of a smart phone. In an embodiment, the first virtual object may also refer to a controllable object in a game program executed on the server 10. When receiving a movement instruction such as an instruction for moving the fighter or the fighter formation, the client 20 may determine that the fighter or the fighter formation is the first virtual object to be moved. For the sake of simplicity, the following description of movement control is based on the single fighter, but it should be understood that a movement of the fighter formation operated in a unified manner may also be controlled similarly, which will not be repeated herein. Before moving, the first virtual object may be in a first state, and when moving, the first virtual object may be in a second state. For example, before moving, the fighter may be in a hovering state, i.e., a state of making a circular motion around a certain position in the map. When moving, the fighter may be in a moving state, i.e., when receiving the movement instruction, the fighter is controlled to move from a current position to a target position.
The second virtual object may refer to a logical object on the server 10, which corresponds to the controllable object in the game program executed on the client 20. The server 10 may determine a position of the second virtual object based on a determination rule preset in the game program executed on the client 20. In this application, the position of the second virtual object is also referred to as a logical position. For example, the determination rule may be that when the fighter is hovering, the second virtual object is located at the center of the circle along which the fighter is hovering, that is, when the fighter is hovering, the center of the circle is the logical position. In an embodiment, the second virtual object may also refer to a logical object on the client 20.
When the client 20 receives a movement instruction for the first virtual object, which is issued in a manner of, for example, a user operating to move the first virtual object on the client to the target location, the client 20 sends the movement instruction to the server 10. In response to the movement instruction, the server 10 determines the second position-parameter and the second movement parameter of the second virtual object, and moves the second virtual object, and sends the second position-parameter and the second movement parameter of the second virtual object to the client 20. In an embodiment, the second position-parameter and the second movement parameter of the second virtual object may be synchronized by another client 20. The client 20 determines the relative orientation parameters between the first virtual object and the second virtual object based on the second position-parameter and the second movement parameter of the second virtual object, and further calculates a first movement parameter of the first virtual object, and moves the first virtual object. In this case, for the movement instruction for moving the first virtual object hovering around the first position to the second position, on one hand, an execution result of the movement instruction on the server 10 may be simplified as moving the second virtual object directly from the first position to the second position without considering the state switching of the first virtual object and the trajectory transition and speed transition processes caused thereby. It may be seen that the computing burden of the server 10 is greatly reduced.
At every moment, the server 10 may determine the second instantaneous position and the second instantaneous speed of the second virtual object. The second instantaneous position of the second virtual object is included in the second position-parameter of the second virtual object, and the second instantaneous speed of the second virtual object is included in the second movement parameter of the second virtual object.
In some embodiments, the second virtual object moves from the first position to the second position at a constant speed, so the second instantaneous speed of the second virtual object is the same at different times. The server 10 may determine the second instantaneous speed based on the determination rule preset in the game program executed on the client 20. For example, the determination rule may be that reference moving speeds of various fighters are determined as corresponding second instantaneous speeds thereof.
In addition, the server 10 may send the second instantaneous position and the second instantaneous speed of the second virtual object at a current moment to the client 20 regularly or irregularly, and communication data between the server 10 and the client 20 are greatly reduced, so as to prevent the client 20 from being unable to smoothly control the movement of the virtual object in a case of a network delay. In some embodiments, the parameters may be synchronized between the server 10 and the client 20 based on a frame, that is, the data are synchronized once per frame, and a duration of each frame, such as one millisecond, ten milliseconds, one second, etc., may be defined according to the specific application scenario.
It may be understood that the server 10 may determine a moving route from the first position to the second position by using an existing path-finding algorithm, so that the second virtual object moves from the first position to the second position at a uniform speed, which will not be described in detail herein.
On the other hand, an execution result of the movement instruction on the client 20 may be understood as controlling the first virtual object to move toward the second virtual object (or may also be understood as controlling the first virtual object to chase the second virtual object), and ensuring that the trajectory transition process and the speed transition process are as smooth as possible during the movement. The above calculation process is implemented and the execution result is shown on the client 20, thereby reducing the calculation burden of the server 10, and presenting a smooth and an intuitive movement trajectory on the client 20 to the user.
Then the client 20 determines the instantaneous distance and the instantaneous relative orientation between the first virtual object and the second virtual object based on the first instantaneous position of the first virtual object and the second instantaneous position of the second virtual object at the current moment. The instantaneous distance refers to a straight-line distance or a Euclidean distance between the first virtual object and the second virtual object, and the instantaneous relative orientation refers to an orientation formed by a straight line connected between the first virtual object and the second virtual object. The instantaneous distance and the relative instantaneous orientation between the first virtual object and the second virtual object are included in the relative orientation parameters between the first virtual object and the second virtual object.
Then, the client 20 determines an instantaneous angle-difference between the first virtual object and the second virtual object, based on the first instantaneous orientation of the first virtual object and the relative instantaneous orientation between the first virtual object and the second virtual object at the current moment. The instantaneous angle-difference refers to an angle formed by the first instantaneous orientation and the relative instantaneous orientation. The instantaneous angle-difference between the first virtual object and the second virtual object is included in the relative orientation parameters between the first virtual object and the second virtual object.
In the calculating step S103, based on the instantaneous distance, the instantaneous angle-difference and the second instantaneous speed, the client 20 calculates the first movement parameters of the first virtual object, the first movement parameters include the first instantaneous speed and the first instantaneous angular speed of the first virtual object.
In some embodiments, the calculating step S103 further includes calculating, by the client 20, the first instantaneous speed based on the following formula: V1i=V2i+di×a, where V1i denotes the first instantaneous speed, V2i denotes the second instantaneous speed, di denotes the instantaneous distance, and a denotes an acceleration coefficient. The acceleration coefficient a is used as a configuration parameter for adjusting the first instantaneous speed V1i. It can be seen that, when the second instantaneous speed V2i and the acceleration coefficient a remain unchanged, the first instantaneous speed V1i of the first virtual object linearly slows down as the instantaneous distance di between the first virtual object and the second virtual object becomes shorter, such that the first virtual object approaches the second virtual object from fast to slow, thereby smoothing the speed transition process. In this embodiment, the fighter approaches the logical position of the logical object from fast to slow.
In some embodiments, the relative orientation parameters further include a following distance between the first virtual object and the second virtual object. The client 20 may determine the following distance based on the determination rule preset in the game program executed on the client. For example, the determination rule may be that when the fighter hovers, the radius of the hovering is determined as the following distance.
In this case, the calculating step S103 further includes calculating, by the client 20, the first instantaneous speed based on the following formula: V1i=V2i+(di−df)×a, where V1i denotes the first instantaneous speed, V2i denotes the second instantaneous speed, di denotes the instantaneous distance, df denotes the following distance, and a denotes the acceleration coefficient. The following distance df is used as a configuration parameter for adjusting the first instantaneous speed V1i. It can be seen that, when the second instantaneous speed V2i and the acceleration coefficient a remain unchanged, the first instantaneous speed V1i of the first virtual object slows down linearly as the instantaneous distance di between the first virtual object and the second virtual object approximates to the following distance df, so that the first virtual object approaches the second virtual object from fast to slow, thereby smoothing the speed transition process, and allowing the first virtual object to transit to a subsequent post-movement action, thereby smoothing the trajectory transition process. In this embodiment, the fighter approaches the logical position of the logical object from fast to slow, and the fighter is allowed to transit to the post-movement action of hovering around the logical position.
In some embodiments, the determining step S101 further includes determining, by the client 20, a first constraint parameter of the first virtual object. The first constraint parameter includes the maximum first instantaneous speed of the first virtual object. The client 20 may determine the maximum first instantaneous speed based on the determination rule preset in the game program executed on the client. For example, the determination rule may be that the maximum moving speed of each of various fighters is determined as the corresponding maximum first instantaneous speed thereof.
In this case, the calculating step S103 further includes calculating, by the client 20, the first instantaneous speed based on the following formula: V1i=V2i+min((di−df)×a, (V1i_max−V2i)), where V1i denotes the first instantaneous speed, V2i denotes the second instantaneous speed, di denotes the instantaneous distance, df denotes the following distance, and a denotes the acceleration coefficient, V1i_max denotes the maximum first instantaneous speed, the function min((di−df)×a, (V1i_max−V2i)) denotes the smaller one of (di−df)×a and (V1i_max−V2i). In other words, the smaller one of (di−df)×a and (V1i_max−V2i) is added to the second instantaneous speed V2i to obtain the first instantaneous speed V1i, thus limiting an upper limit of the first instantaneous speed V1i to prevent the first virtual object from moving too fast, thereby smoothing the speed transition process.
In some embodiments, the first constraint parameter further includes the minimum first instantaneous speed of the first virtual object. The client 20 can determine the minimum first instantaneous speed based on the determination rules preset in the game program executed on the client 20. For example, the determination rule may be that the minimum moving speed of each of various fighters is determined as the corresponding minimum first instantaneous speed thereof. If the first instantaneous speed of the fighter is less than the corresponding minimum first instantaneous speed, the fighter will show a hovering-like posture because it moves too slowly.
In this case, the calculating step S103 further includes calculating, by the client 20, the first instantaneous speed based on the following formula: V1i=max((V2i+min((di−df)×a, (V1i_max−V2i))), V1i_min), where V1i denotes the first instantaneous speed, V2i denotes the second instantaneous speed, di denotes the instantaneous distance, df denotes the following distance, and a denotes the acceleration coefficient, V1i_max denotes the maximum first instantaneous speed, V1i_min denotes the minimum first instantaneous speed, the function max((V2i+min((di−df)×a, (V1i_max−V2i))), V1i_min) denotes the larger one of (V2i+min((di−df)×a, (V1i_max−V2i))) and the minimum first instantaneous speed V1i_min. In other words, the larger one of (V2i+min((di−df)×a, (V1i_max−V2i))) and the minimum first instantaneous speed V1i_min is selected to obtain the first instantaneous speed, thus limiting a lower limit of the first instantaneous speed to prevent the fighter from showing the hovering-like posture, thereby smoothing the speed transition process.
In some embodiments, the calculating step S103 further includes calculating, by the client 20, the first instantaneous angular speed based on the following formula: w1i=Δαi×s, where w1i denotes the first instantaneous angular speed, Δαi denotes an instantaneous angle-difference, s denotes a steering coefficient, and the steering coefficient s is used as a configuration parameter for adjusting the first instantaneous angular speed.
It can be seen that, while the steering coefficient s remains unchanged, the first instantaneous angular speed w1i of the first virtual object becomes slows down linearly as the instantaneous angle-difference Δαi between the first virtual object and the second virtual object becomes smaller, causing the first virtual object to rotate itself from fast to slow to face the second virtual object, thus smoothing the trajectory transition process. In this embodiment, the fighter rotates itself from fast to slow to face the logical position of the logical object.
In some embodiments, the determining step S101 further includes determining, by the client 20, the first constraint parameter of the first virtual object, and the first constraint parameter includes the maximum first instantaneous angular speed of the first virtual object. The client 20 may determine the maximum first instantaneous angular speed based on the determination rule preset in the game program executed on the client. For example, the determination rule may be that the maximum rotation angular speed of each of various fighters is determined as the corresponding maximum first instantaneous angular speed thereof.
In this case, the calculating step S103 further includes calculating, by the client 20, the first instantaneous angular speed based on the following formula: w1i=min(Δαi×S, w1i_max), where w1i denotes the first instantaneous angular speed, Δαi denotes the instantaneous angle-difference, s denotes the steering coefficient, w1i_max denotes the maximum first instantaneous angular speed, the function min(Δαi×s, w1i_max) denotes the smaller one of Δαi×s and w1i_max. In other words, the smaller one of Δαi×s and the maximum first instantaneous angular speed w1i_max is selected to obtain the first instantaneous angular speed w1i, thus limiting the upper limit of the first instantaneous angular speed w1i to prevent the first virtual object from rotating too fast, thereby smoothing the trajectory transition process.
In a presenting step S105, based on the first instantaneous speed and the first instantaneous angular speed, the client 20 controls the first virtual object to move toward the second virtual object.
Returning to
In some embodiments, the calculating step S103 further includes calculating, by the client 20, a first inclination parameter of the first virtual object based on the first instantaneous angular speed. The first inclination parameter includes a first instantaneous inclination-angle of the first virtual object.
In this case, the presenting step S105 further includes controlling, by the client 20, the first virtual object to incline toward the second virtual object based on the first instantaneous inclination-angle.
In this embodiment, the fighter inclines at a certain angle while moving toward the logical position of the logical object. This angle changes in real time according to the first instantaneous angular speed of the fighter, which can restore the steering posture of the fighter in the real scene and save additional animation resources due to no need to animate inclinations at different angles in advance.
In some embodiments, the first instantaneous inclination-angle is calculated by the client 20 based on the following formula: α1i=min(w1i×c, 90°), where α1i denotes the first instantaneous inclination-angle, w1i denotes the first instantaneous angular speed, c denotes an inclination coefficient, a function min(w1i×c, 90°) denotes the smaller one of w1i×c and 90°. The inclination coefficient c is used as a configuration parameter for adjusting the first instantaneous inclination-angle α1i. In other words, if w1i×c is greater than 90°, the first instantaneous inclination-angle α1i can only be 90°, such that the first virtual object will not incline overly, thereby more realistically restoring the steering posture of the fighter in the real scene.
To sum up, according to the method for controlling movement of virtual object in the embodiments of the present application, for the movement instruction instructing to move the first virtual object hovering around the first position to the second position, on the one hand, the execution result of the movement instruction on the server 10 may be simplified as moving the second virtual object directly from the first position to the second position without considering the state switching of the first virtual object and the trajectory transition and speed transition processes caused thereby, thus greatly reducing the computing burden of the server 10, and greatly reducing the communication data between the server 10 and the client 20. On the other hand, the execution result of the movement instruction on the client 20 may be understood as controlling the first virtual object to move towards the second virtual object (or may be understood as controlling the first virtual object to chase the second virtual object), and ensuring that the trajectory transition process and the speed transition process are as smooth as possible during the movement.
