Background

The virtual character can perform a series of activities in the three-dimensional virtual world, for example, the virtual character moves from a static state in the virtual environment, or the virtual character stops moving from the static state in the virtual environment.

step 202: a first avatar located in a virtual environment is displayed.

The first virtual role is the role that is hosted on the local client. The first avatar includes, but is not limited to, at least one of a virtual character, a virtual animal, and an animation character.

The virtual environment is a three-dimensional virtual environment. Optionally, the virtual environment is a two-dimensional virtual environment, or alternatively, the virtual environment is a 2.5-dimensional virtual environment.

Optionally, at least one of a move control, a set control, a dialog box, a volume adjustment control, a jump control, a squat control, a care, a view switching control, a recording control, and a microphone icon may also be displayed on the user interface of the client. The movement control is used for controlling the movement of the virtual character in the virtual world. The setting control is used for setting basic parameters on the client, and the basic parameters include but are not limited to at least one of volume, brightness, contrast, picture definition, gray scale and frame number. A dialog box is an area where user dialogs are displayed. The volume adjusting control is used for adjusting the volume of the client. And the jumping control is used for controlling the virtual character to jump. The squatting control is used for controlling the virtual character to squat. The isocenter is used to assist the user in targeting virtual objects in the virtual environment. The view switching control is used for switching the view of the virtual world observed by the user, for example, from a first person view to a third person view, or from the third person view to the first person view. The recording control is used for recording the voice of the user. The microphone icon is used to indicate whether the microphone is in an on state.

Illustratively, as shown in fig. 3, other avatars 301, a move control 302, a set control 303, a volume adjustment control 304, a jump control 305, a squat control 306, a microphone icon 307 are displayed on the user interface.

Optionally, the user interface is a view of the first avatar as viewed by the camera model in the virtual environment.

Optionally, the camera model automatically follows the virtual character in the virtual environment, that is, when the position of the virtual character in the virtual environment changes, the camera model changes while following the position of the virtual character in the virtual environment, and the camera model is always within the preset distance range of the virtual character in the virtual environment. Optionally, the relative positions of the camera model and the virtual character do not change during the automatic following process.

The camera model is a three-dimensional model positioned around a virtual character in a virtual environment, and when a first-person visual angle is adopted, the camera model is positioned near the head of the virtual character or positioned at the head of the virtual character; when a third person perspective view is adopted, the camera model can be located behind the virtual character and bound with the virtual character, or located at any position away from the virtual character by a preset distance, the virtual character located in the virtual environment can be observed from different angles through the camera model, and optionally, when the third person perspective view is the over-shoulder perspective view of the first person, the camera model is located behind the virtual character (such as the head and the shoulder of the virtual character). Optionally, the viewing angle includes other viewing angles, such as a top viewing angle, in addition to the first person viewing angle and the third person viewing angle; the camera model may be positioned over the head of the virtual character when a top view is used, which is a view of viewing the virtual environment from an aerial top view. Optionally, the camera model is not actually displayed in the virtual environment, i.e. the camera model is not displayed in the virtual environment displayed by the user interface.

To illustrate an example where the camera model is located at any position away from the virtual character by a preset distance, optionally, one virtual character corresponds to one camera model, and the camera model may rotate with the virtual character as a rotation center, for example: the camera model is rotated with any point of the virtual character as a rotation center, the camera model rotates not only angularly but also shifts in displacement during the rotation, and the distance between the camera model and the rotation center is kept constant during the rotation, that is, the camera model rotates on the surface of a sphere with the rotation center as the sphere center, wherein any point of the virtual character can be the head, the trunk or any point around the virtual character, which is not limited in the embodiment of the present application. Optionally, when the virtual character is observed by the camera model, the center of the view angle of the camera model points to the direction in which the point of the spherical surface on which the camera model is located points to the center of the sphere.

Optionally, the camera model may also observe the virtual character at a preset angle in different directions of the virtual character.

Referring to fig. 4, schematically, a point is determined in the virtual character 41 as a rotation center 42, and the camera model rotates around the rotation center 42, and optionally, the camera model is configured with an initial position, which is a position above and behind the virtual character (for example, a rear position of the brain). Illustratively, as shown in fig. 4, the initial position is position 43, and when the camera model rotates to position 44 or position 45, the direction of the angle of view of the camera model changes as the camera model rotates.

Step 204: and receiving a movement control operation, wherein the movement control operation is used for controlling the first virtual character to change the movement state in the virtual environment, and the movement state comprises a standing state and a traveling state.

The movement control operation is to control the first virtual character to change the movement state in the virtual environment by pressing one or more preset physical keys. Alternatively, the user may perform the movement control operation by a signal generated by a tap, a long press, a click, a double click, and/or a slide on the touch screen.

Alternatively, when the terminal is a VR (Virtual Reality) device, the movement control operation is a behavior action of the user in a real environment. For example, if the user steps forward in the real environment, the virtual character in the virtual environment correspondingly steps forward.

Optionally, the moving state further comprises at least one of a jumping state, a turning state, a takeoff state, a landing state, a descending state, and an ascending state. Illustratively, the movement control operation is for controlling the first avatar to change from an immediately state to a jumping state in the virtual environment.

The standing state means that the virtual character is static in the virtual environment, and the advancing state means that the virtual character advances at a constant speed. Illustratively, the traveling state refers to the virtual character traveling in the virtual environment at a speed of 3 m/s.

Step 206: in response to the movement control operation, a first transition animation frame corresponding to a first movement distance, which is a movement distance of the first virtual character in a first transition stage of the change in the movement state, is determined in the first transition animation.

The first transition phase refers to a process in which the first avatar switches the moving state. For example, in the present embodiment, the first transition phase refers to a process in which the first avatar changes from a standing state to a traveling state, or the first transition phase refers to a process in which the first avatar changes from a traveling state to a standing state.

Illustratively, when the speed of the first avatar in the virtual environment is 0, the first avatar is considered to be in a standing state, and the moment when the movement control operation is received is considered to be the starting moment of the first transition phase; when the first virtual character accelerates from the station state to the preset speed, so that the first virtual character keeps the preset speed to move at a constant speed, the moment when the first virtual character reaches the preset speed is regarded as the ending moment of the first transition stage, or after the first virtual character reaches the preset speed and the first virtual character moves at the preset speed at the constant speed for a preset distance, the moment when the first virtual character moves at the constant speed for the preset distance at the preset speed is regarded as the ending moment of the first transition stage.

The first transition animation is an animation that drives a three-dimensional model of the first virtual character using a skeletal model of the first virtual character. The first transition animation belongs to one of three-dimensional animations.

Optionally, the first transition animation is an animation that the first virtual character is displayed in a transition phase of the change in the movement state. Illustratively, a first transition animation is displayed when the first virtual character changes from an in-station state to a travel state. Optionally, the movement state comprises at least one of a standing state, a traveling state, a jumping state, a turning state, a take-off state, a landing state, a descending state, and an ascending state.

Optionally, the first transition animation is associated with a type of movement state change. Illustratively, a transitional animation 1 is displayed when the first virtual character changes from an in-station state to a travel state. When the first virtual character changes from the traveling state to the standing state, a transition animation 2 is displayed.

Optionally, the first transition animation is designed by the technician at his or her discretion.

Optionally, the first transition animation is derived by capturing real-person motion through motion capture techniques.

Optionally, the first transition animation comprises an animation observed from a different perspective. Illustratively, viewing the first virtual character from a front perspective of the first virtual character results in a first transition animation, or viewing the first virtual character from a back perspective of the first virtual character results in a first transition animation.

Optionally, the perspective of the first transition animation is determined from the perspective of the local client.

A transitional animation may transition between two different animations. In this embodiment, each moving state of the virtual character has a corresponding animation, for example, the virtual character displays a standing animation when standing, and the virtual character displays a moving animation when moving. When two different animations are directly connected together, the connection of the two animations appears unnatural, for example, when the standing animation and the moving animation of the virtual character are directly connected together, and after the standing animation is played, the moving animation is played, the action of the virtual character appears unnatural, and the virtual character may have problems of shaking, dragging and the like, so that the connection of the two animations appears natural by adding the transition animation.

The first transition animation frame is one frame image corresponding to the first moving distance in the first transition animation.

Optionally, the first transitional animation frame is at least one of a two-dimensional image, a 2.5-dimensional image, and a three-dimensional image.

Step 208: and playing a first transition animation frame corresponding to the first moving distance to obtain the moving animation of the first virtual character in the first transition stage.

In the process of playing the first transition animation frame, since the first transition animation frame is determined according to the first moving distance of the first virtual character, when the moving animation is played, the whole playing process is smooth and continuous.

Illustratively, as shown in fig. 5, during the process of the first virtual character 500 changing from a standing state to a traveling state, the transition animation frame 501 shows the first virtual character 500 in a standing state, and when the first virtual character 500 starts traveling and has traveled a distance, the transition animation frame 502 is displayed, and the body posture of the first virtual character 500 has changed. When the virtual character travels a further distance and the transitional animation frame 503 is displayed, the body posture of the first virtual character 500 changes again. After the first avatar 500 enters the traveling state, a transition animation frame 504 is displayed, in the transition animation frame 504, the posture of the first avatar 500 indicates that the first avatar 500 is traveling (fig. 5 only shows a few representative transition image frames in the process that the first avatar 500 changes from the standing state to the traveling state, and in the actual implementation process, the number of the transition image frames is adjusted according to actual needs).

Optionally, the animation frame of the last m frames of the first transition animation corresponds to the moving state after the moving state changes, and m is a positive integer. Illustratively, when the first transition animation has a total of 50 frames and the first transition animation is changed from the standing state to the traveling state, the animation frame of the last 5 frames of the first transition animation appears as the standing state of the first virtual character.

Optionally, the animation frames of the first n frames of the first transition animation correspond to the moving state before the moving state changes, and n is a positive integer. Illustratively, when the first transition animation has a total of 50 frames and the first transition animation is changed from the standing state to the traveling state, the animation frame of the last 5 frames of the first transition animation appears as the standing state of the first virtual character.

Illustratively, as shown in fig. 6, during the process of the first virtual character 600 changing from the traveling state to the standing state, the transition animation frame 601 shows that the first virtual character 600 is in the traveling state, and when the first virtual character 600 starts to stop and a distance has elapsed, the transition animation frame 602 is displayed, and the body posture of the first virtual character 600 has changed. When the virtual character travels a further distance, the transitional animation frame 603 is displayed, and the body posture of the first virtual character 600 changes again. After the first avatar 600 enters the standing state, a transition animation frame 604 is displayed, in the transition animation frame 604, the posture of the first avatar 600 indicates that the first avatar 600 is in the standing state (fig. 6 only shows a few representative transition image frames in the process of the first avatar 600 changing from the advancing state to the standing state, and in the actual implementation process, the number of the transition image frames is adjusted according to actual needs).

In summary, in this embodiment, when the virtual character changes in the moving state, the corresponding transition animation frame is played according to the moving distance of the virtual character in the virtual environment, and the transition animation frame is continuously played to obtain the complete moving animation. When the change of the moving state of the virtual character is displayed, the animation and the displacement of the first virtual character are matched, the phenomenon of 'sliding' is avoided, the reality is enhanced more naturally and smoothly. And when the server and the client carry out data interaction, only an instruction with a small data volume and the information of the position point need to be sent, so that the data interaction volume between the client and the server can be reduced. Moreover, the calculation of the character model of the virtual character is executed on the client instead of the server, so that the calculation pressure of the server can be reduced.

In the following optional embodiment, the moving distance of the virtual character is matched with the transition animation frame in the transition animation, so that the virtual character can obtain smoother transition animation to show the change of the moving state of the virtual character in the change process of the moving state.

Fig. 7 is a flowchart illustrating a control method for a virtual character according to an exemplary embodiment of the present application. The method may be performed by the first terminal 110 or the second terminal 130 or a client on the first terminal 110 or a client on the second terminal 130 shown in fig. 1, and the method includes:

step 701: a first avatar located in a virtual environment is displayed.

The movement control operation is used for controlling the first virtual character to change the movement state in the virtual environment, wherein the movement state comprises a standing state and a traveling state.

Illustratively, as shown in fig. 3, a virtual character 301, a movement control 302, a setting control 303, a volume adjustment control 304, a jump control 305, a squat control 306, a recording control 307, and a microphone icon 308 are displayed on the user interface.

Step 702: a movement control operation is received.

Optionally, the movement state comprises at least one of a standing state, a traveling state, a jumping state, a turning state, a take-off state, a landing state, a descending state, and an ascending state. Illustratively, the movement control operation is for controlling the first avatar to change from an immediately state to a jumping state in the virtual environment.

Step 703: in response to the movement control operation, a reference position point of the first virtual character is acquired at a first transition stage of the movement state change.

The reference position point is determined according to the change mode of the movement state of the first virtual character in the virtual environment. Illustratively, when the first avatar changes from a standing state to a traveling state, the reference position point 1 corresponds to, and when the first avatar changes from the traveling state to a standing state, the reference position point 1 and the reference position point 2 correspond to, and are two different points.

Illustratively, when the first avatar changes from the standing state to the traveling state, the reference location point is obtained by:

in response to the movement control operation, a start position point of the first avatar is determined as a reference position point at a first transition stage where the first avatar changes from the standing state to the traveling state.

Optionally, a coordinate system is established in the virtual environment, and the position point of the first virtual character is recorded through the coordinate system.

Optionally, the coordinates of the center point of the first virtual character model are used as the current position of the first virtual character.

For example, if the first avatar is standing at position a in the virtual environment and the first avatar is going to change from a standing state to a traveling state, the position a where the first avatar stands may be regarded as the starting position of the first avatar, and may also be regarded as the reference position point.

Illustratively, when the first avatar changes from the traveling state to the standing state, the reference position point is obtained by:

1. in response to the movement control operation, a predicted stopping point is calculated from the traveling parameters of the first avatar at a first transition stage where the first avatar changes from the traveling state to the standing state.

The travel parameter includes at least one of speed magnitude, speed direction, friction, air resistance, acceleration.

Illustratively, the first avatar travels in a first direction, the first direction is determined as a positive direction of the x-axis, and when the first avatar is ready to be converted from the traveling state to the standing state at x-0, if the speed of the first avatar is 4m/s, the acceleration is-2 m/s²Then the first avatar will stop at x-4 and enter the standing state.

The travel parameter affects a movement distance required for the change in the motion state of the first virtual character. For example, when the first avatar changes from a traveling state to a standing state, the first avatar performs a deceleration movement, the acceleration of the first avatar is affected by ground friction, and when the ground friction is large, the first avatar receives a large acceleration opposite to the speed direction, and the first avatar is more easily decelerated, so that the first avatar changes from the traveling state to the standing state within a short moving distance. Similarly, when the first avatar changes from the traveling state to the standing state, the air resistance also affects the moving distance required for the first avatar to change from the traveling state to the standing state.

2. The predicted stopping point is determined as a reference position point.

Step 704: a first movement distance between the current position of the first virtual character and the reference position point is calculated.

Optionally, a coordinate system is established in the virtual environment, and the current position and the reference position point are recorded through the coordinate system. Illustratively, the coordinates of the current position in the virtual environment are (0, 4), the coordinates of the reference position point in the virtual environment are (0, 7), and the first movement distance is 3.

Step 705: a target timestamp is determined from the first transition animation curve based on the first movement distance.

The transition animation curve is used to represent a relationship between a moving distance and a time stamp in the transition animation.

Since different transition animations are used for different movement state changes, the transition animation curve is determined according to the movement state change. Illustratively, fig. 8 shows a transition animation graph of a transition animation corresponding to a change of the first virtual character from an immediately stationary state to a traveling state, in which a horizontal axis represents a time stamp and a vertical axis represents a first movement distance. Fig. 9 shows a transition animation graph of a transition animation corresponding to the change of the first virtual character's traveling state from the standing state, and likewise, the horizontal axis represents a time stamp and the vertical axis represents the first movement distance in the graph.

Illustratively, as shown in FIG. 8, finding the first movement distance represents point 801 in FIG. 8, from which point 801 a point 802 is derived from the transition animation graph, the point 802 representing the target timestamp.

Illustratively, as shown in FIG. 9, finding the first movement distance represents point 901 in FIG. 9, and finding point 902 from the transition animation graph according to point 901, point 902 represents the target timestamp.

Step 706: a first transition animation frame corresponding to the target timestamp is determined in the first transition animation.

The first transition animation is played according to the time stamp, and each frame in the first transition animation has the corresponding time stamp.

Step 707: and playing a first transition animation frame corresponding to the first moving distance to obtain the moving animation of the first virtual character in the first transition stage.

Illustratively, as shown in fig. 6, during the process of the first virtual character 600 changing from the traveling state to the standing state, the transition animation frame 601 shows that the first virtual character 600 is in the traveling state, and when the first virtual character 600 starts to stop and a distance has elapsed, the transition animation frame 602 is displayed, and the body posture of the first virtual character 600 has changed. When the virtual character travels a further distance, the transitional animation frame 603 is displayed, and the body posture of the first virtual character 600 changes again. After the first avatar 600 enters the standing state, a transition animation frame 604 is displayed, in the transition animation frame 604, the posture of the first avatar 600 indicates that the first avatar 600 is standing (fig. 6 only shows a few representative transition image frames in the process of the first avatar 600 changing from the advancing state to the standing state, and in the actual implementation process, the number of the transition image frames is adjusted according to actual needs).

In summary, in this embodiment, when the virtual character changes in the moving state, the corresponding transition animation frame is played according to the moving distance of the virtual character in the virtual environment, and the transition animation frame is continuously played to obtain the complete moving animation. When the change of the movement state of the virtual character is displayed, the movement state is more natural and smooth, and the sense of reality is enhanced. And when the server and the client carry out data interaction, only an instruction with a small data volume and the information of the position point need to be sent, so that the data interaction volume between the client and the server can be reduced. Moreover, the calculation of the character model of the virtual character is executed on the client instead of the server, so that the calculation pressure of the server can be reduced.

And moreover, relatively coherent picture representation can be obtained by matching the animation frame of the first virtual character through the moving distance of the first virtual character, meanwhile, the client can determine the animation only by performing single matching calculation, the calculation amount of the client can be reduced, and the timeliness of transition animation representation is improved.

In the following alternative embodiment, the virtual environment may further have a second virtual character, which is manipulated by a user on another client or an AI (Artificial Intelligence), different from the first virtual character, and is manipulated by a user on the local client, so that it is necessary to describe how the second virtual character is represented on the local client.

Fig. 10 is a flowchart illustrating a control method for a virtual character according to an exemplary embodiment of the present application. The method may be performed by the first terminal 110 or the second terminal 130 or a client on the first terminal 110 or a client on the second terminal 130 shown in fig. 1, and the method includes:

step 1001: a second avatar located in the virtual environment is displayed.

The second virtual character is a character in the virtual environment that is different from the first virtual character. Optionally, the second virtual role is a user-controlled role on other clients, or the second virtual role is an AI-controlled role.

Optionally, the second avatar includes, but is not limited to, at least one of a virtual character, a virtual animal, and an animation character.

Step 1002: and receiving a movement state change instruction sent by the server.

The movement state change instruction is used for controlling the second virtual character to change the movement state in the virtual environment. When the second virtual character is a user-controlled character on the other client, the movement state change instruction is generated upon receiving a movement control operation on the other client.

Optionally, the moving state comprises a standing state and a traveling state.

Optionally, the moving state further comprises at least one of a jumping state, a turning state, a takeoff state, a landing state, a descending state, and an ascending state. For example, the change of the movement state may be a change from a standing state to a jumping state.

Step 1003: in response to the movement state change instruction, a second transition animation frame corresponding to a second movement distance is determined in the second transition animation.

Optionally, when the change of the movement state comprises a change from an immediately state to a travelling state, the step comprises the sub-steps of:

1. in response to the movement state change instruction, a second movement distance between the current position and the starting position point of the second virtual character is calculated in a second transition phase of the movement state change of the second virtual character.

Optionally, a coordinate system is established in the virtual environment, and the current position and the starting position point of the second virtual character are recorded through the coordinate system.

Optionally, the coordinates of the center point of the second virtual character model are used as the current position of the second virtual character.

Illustratively, the second avatar is originally standing at position B in the virtual environment, and the second avatar is about to change from the standing state to the traveling state, and then the position B where the second avatar originally stands is recorded as the starting position of the second avatar.

2. And determining a second transition animation frame from the second transition animation according to the second moving distance.

Further, determining a target timestamp from the second transition animation curve according to the second moving distance; a second transition animation frame is determined from the second transition animation according to the target timestamp.

The transition animation curve is used to represent a relationship between a moving distance and a time stamp in the transition animation. Wherein the horizontal axis of the second transition animation curve represents the time stamp and the vertical axis represents the second movement distance.

Optionally, when the change of the moving state comprises a change from a traveling state to a standing state, the moving state change instruction comprises a predicted stopping point of the second avatar, the step comprising the sub-steps of:

1. in response to the movement state change instruction, a second movement distance between the current position of the second virtual character and the predicted stop point of the second virtual character is calculated in a second transition phase of the movement state change of the second virtual character.

Step 1004: and playing a second transition animation frame corresponding to the second moving distance to obtain the moving animation of the second virtual character in the second transition stage.

The second transition phase refers to a process of the second avatar switching the moving state. For example, in the present embodiment, the second transition phase refers to a process in which the second avatar changes from the standing state to the traveling state, or the second transition phase refers to a process in which the second avatar changes from the traveling state to the standing state.

Illustratively, when the speed of the second avatar in the virtual environment is 0, the second avatar is considered to be in a standing state, and the time when the movement control operation is received is considered to be the starting time of the second transition phase; and when the second virtual character accelerates from the station state to the preset speed, so that the second virtual character keeps the preset speed to move at a constant speed, considering the moment when the second virtual character reaches the preset speed as the ending moment of the second transition stage, or considering the moment when the second virtual character reaches the preset speed and the second virtual character moves at the preset speed at the constant speed for a preset distance as the ending moment of the second transition stage.

In the process of playing the second transitional animation frame, since the second transitional animation frame is determined according to the second moving distance of the second virtual character, when the moving animation is played, the whole playing process is smooth and continuous.

In summary, in this embodiment, when the virtual character changes in the moving state, the corresponding transition animation frame is played according to the moving distance of the virtual character in the virtual environment, and the transition animation frame is continuously played to obtain the complete moving animation. When the change of the movement state of the virtual character is displayed, the movement state is more natural and smooth, and the sense of reality is enhanced. And the transition animation frame of the virtual character is determined by moving the distance, so that the data interaction amount between the client and the server can be reduced, and the calculation pressure of the server is reduced.

And only the moving state change instruction needs to be transmitted, so that the transmitted data volume is small, the dependence on the network is small, and the smooth display of the virtual character transition animation can be realized even under the condition of large network delay.

Fig. 11 and 12 are flowcharts each illustrating a control method of a virtual character according to an exemplary embodiment of the present application. The change in the movement state of the user-controlled first avatar at the local client may involve a change in the movement state of the first avatar displayed at the local client, server, and other clients.

On the local client, the first avatar starts to change from the standing state to the traveling state in step 1101, and the local client sends a start movement notification to the server. In step 1102, the local client records a starting location point. In step 1103, the local client calculates a movement distance between the current position of the first avatar and the reference position point. In step 1104, the local client determines a travel transition animation frame from the travel transition animation according to the movement distance. In step 1105, the local client plays the moving transition animation frame according to the moving distance to obtain the moving animation of the first virtual character in the moving transition stage. In step 1106, the first avatar on the local client travels at a uniform speed. In step 1107, the first avatar on the local client starts to change from the traveling state to the standing state, and the local client sends a start stop notification to the server. In step 1108, the local client calculates a predicted stopping point according to the traveling parameters of the first virtual character, and the local client sends the predicted stopping point to the server. In step 1109, the local client calculates a movement distance between the current position of the first avatar and the predicted stopping point. In step 1110, the local client determines a standing transition animation frame from the standing transition animation according to the moving distance. In step 1111, the local client plays the standing transition animation frame according to the moving distance to obtain the moving animation of the first virtual character in the standing transition stage. In step 1112, the local client displays the first avatar to stand.

On the server, in step 1113, the first avatar starts to change from the standing state to the traveling state upon receiving the start movement notification sent by the local client. In step 1114, the first avatar in the server travels at a uniform speed. In step 1115, upon receiving a start stop notification sent by the local client, the first avatar starts to change from the traveling state to the standing state. In step 1116, the server synchronizes the predicted stopping points. In step 1117, the first avatar in the server stands.

On the other client, the other client receives the start move instruction sent by the server and the first avatar starts to change from the standing state to the traveling state in step 1118. In step 1119, the other client records the starting location point. In step 1120, the other client calculates a movement distance between the current position of the first avatar and the reference position point. In step 1121, the other client determines a travel transition animation frame from the travel transition animation according to the movement distance. In step 1122, the other clients play the traveling transition animation frame according to the moving distance, so as to obtain the moving animation of the first virtual character in the traveling transition phase. In step 1123, the other client displays the first avatar to travel at a constant speed. In step 1124, the first avatar starts to change from the traveling state to the standing state after the other client receives the start stop instruction sent by the server. In step 1125, after receiving the predicted stopping point, other clients calculate the moving distance between the current position of the first avatar and the predicted stopping point. In step 1126, the other clients determine a standing transition animation frame from the standing transition animation according to the moving distance. In step 1127, the other clients play the standing transition animation frame according to the moving distance to obtain the moving animation of the first virtual character in the standing transition stage. In step 1128, the other client displays the first avatar to stand.
