Based on the hardware structure of fig. 1, an embodiment of the collision synchronization method of the present invention is provided.
Referring to fig. 2, fig. 2 is a flowchart illustrating a first embodiment of the collision synchronization method according to the present invention.
In a first embodiment, the collision synchronization method includes the steps of:
step S10, the current client acquires an initial speed of the corresponding current object, and uploads the initial speed to the server, so that the server sends the initial speed to other clients corresponding to other objects of the current object in the same game scene.
It should be noted that the current scene includes objects in the same game scene, and each object corresponds to one client, and each object is identified by a feature tag, so as to distinguish from other client players.
It can be understood that, because the same collision effect needs to be displayed on the interfaces of the respective clients, most manufacturers currently adopt a synchronization scheme that is a scheme of state synchronization and data compression, that is, calculation is performed at one client, data is compressed after the calculation of other clients completes the effect, and then the data is transmitted to the server, the server is distributed to other clients, and the other clients perform interpolation processing on some effects and then display the result. However, even if compression processing is performed, when multiple collision objects exist, the position change of each different object needs to be synchronized to other clients through the server, and therefore a problem arises that the synchronized data volume is too large, and game experience is seriously affected in an environment with a poor network.
In this embodiment, the initial speed includes an initial acceleration of a current operation object in a current scene, that is, a current acceleration magnitude and a current direction, the initial speed includes initial accelerations of other objects in the current scene, and a motion trajectory of each object may be calculated according to the acceleration magnitude, so that each object may be drawn according to the motion trajectory.
In a specific implementation, each client may receive each object information corresponding to another client sent by the server, find each corresponding object through each object information, for example, may obtain Identification (ID) information of each current object, identify each object through the ID information, that is, extract a feature tag in the data information by receiving the data information sent by the server, and find each object corresponding to the feature tag in a preset relationship mapping table according to the feature tag.
And step S20, determining the motion track of the current object according to the initial speed, and judging whether the current object and other objects collide according to the motion track.
It should be noted that, in this embodiment, the running track information may be recorded through a snapshot, and the position information of the running track may also be recorded through other forms.
In the embodiment, the whole motion track and the state of the ball are calculated according to data in a scene, the calculation result is stored in a snapshot, the position information and the time information of the motion track are recorded through the snapshot, and the ball is drawn through the motion track, so that a client does not need to send updated position information to a server in real time, the server sends the position information to other clients, information interaction between the client and the server is reduced, and synchronous flow is reduced.
To facilitate the management of the respective object information, in the present embodiment, the position information of the respective objects may be stored by the data structure of the respective object frames, and the time information of the current scene may be stored by the data structure of the scene frames, for example, when the respective objects are balls, the data structure of the respective object information as shown in fig. 3 stores the positions of all balls in the scene, discriminates by IDs, and records the relative times of all ball snapshots and the current snapshot by the snapshot frame, wherein the relative times are relative to the time of the first frame. The frame of the ball only needs to store the ID and the position information in a preset area, other information is stored in other storage areas, the label information and the position information are recorded through each object frame, and the relative time information is recorded through the scene frame.
Step S30, when a collision occurs, updating the initial speed of the current object and the other objects, and recording the target position information of the current object and the other objects until the updated initial speed of the current object and the other objects is a preset speed.
It should be noted that, when the preset speed is zero, that is, each object in the scene is in a static state, where the collision includes whether each object collides with the prop and whether each object collides with each object, which is described by taking a ball as an example, in order to determine whether two or more balls collide, in this embodiment, it may be determined whether a distance between two centers of the ball is smaller than a sum of radii of the two balls, and when the distance between the two centers of the ball is smaller than the sum of radii of the two balls, it is determined that the two balls collide, and correspondingly, when the distance between the two centers of the ball is larger than the sum of radii of the two balls, it is determined that the two balls do not collide. When judging whether each object collides with the prop, the distance between the ball and the wall body can be judged, when the distance between the center of the ball and the wall body is smaller than the radius of the ball, the collision between the ball and the wall body is judged, and correspondingly, when the distance between the center of the ball and the wall body is larger than the radius of the ball, the collision between the ball and the wall body is judged.
It can be understood that whether each object collides is judged, so that the acceleration vector of each object is updated, the position information of each object is updated through the updated acceleration vector, and the current position information is saved in a snapshot form.
As shown in the flow diagram of the calculation of the motion trajectory of each object shown in fig. 4, firstly, whether a ball is in motion is checked, when a ball is in motion, whether each ball collides with a wall is calculated and the check result is stored, whether each ball collides with the wall is detected and the detection result of each ball is stored, the ball speed is updated according to the collision result, the ball speed is attenuated according to the friction force, the frame time and other related factors, the updated position information of the ball is calculated according to the updated ball speed, and the current position information and the current time information are recorded through snapshot.
It can be understood that, before recording the updated position information of the ball in a snapshot manner, it is determined whether a collision occurs, and in case of a collision, the updated position information is recorded by snapshot, and in case of no collision and in case of statistics of preset continuous frames, the position information of each object may also be recorded by snapshot in case that no collision occurs to each object in the current frame, so as to reduce the position information of the ball whose recording position has not changed, save memory space, for example, in case of no collision occurs to 10 continuous frames of the ball a, record the position of the ball a, thereby preventing the ball a from being lost for too long time and failing to achieve the effect of continuous motion.
It should be noted that the recorded position information of each frame is the picture information of each frame recorded within a preset time, for example, 10ms, so as to accurately record the motion state of each frame. The collision check is a loop iteration, the exit condition is that all the balls are static, and a simple game collision iteration process is realized. After acquiring the state of one frame, the collision condition is processed by one snapshot here. The storage condition of the snapshot is that collision occurs or the snapshot is not stored for a preset number of frames, the iteration time of each frame is a self-defined preset time, and the preset time and the preset number can be set when the engine is initialized.
And step S40, drawing the current object and other objects according to the target position information to realize collision synchronization.
In the collision synchronization method provided by this embodiment, the initial speed of the corresponding current object is obtained by the current client, the actual motion trajectory of each object is determined according to the initial speed and a preset rule, and each object is drawn according to the motion trajectory, so that collision synchronization of each object in the current scene of each client is realized, and data interaction between the client and the server is reduced.
Further, as shown in fig. 5, a second embodiment of the collision synchronization method according to the present invention is proposed based on the first embodiment, and in this embodiment, the step S10 specifically includes:
step S101, obtaining an initial speed of a corresponding current object, and uploading the initial speed to a server, so that the server sends the initial speed to other clients corresponding to other objects of the current object in the same game scene through transparent transmission.
It should be noted that the data of the initial speed synchronization is the initial speed of the ball manipulated by the client, that is, after the client sends the initial speed to the server, the server transparently transmits the data to all clients in the same game.
In order to ensure the quality of data, in this embodiment, the server transparently transmits the synchronous data to other clients, so as to reduce the loss of the synchronous data, and since the server transmits the synchronous data through transparent transmission, the transmitted service does not need to be processed, and in the transmission process of the data, the synchronous data is not changed in any form, i.e., is not truncated, is not grouped, is not encoded, is not encrypted, is not confused, and the like, so that the efficiency of data transmission is ensured, the condition that the data is not transmitted synchronously in the transmission process is avoided, and the game experience is improved.
In the embodiment, the server transparently transmits the synchronous data to each client, so that the transmission synchronization of the data is ensured and the game experience of the user is improved on the basis of improving the transmission efficiency.
Further, as shown in fig. 6, a third embodiment of the collision synchronization method according to the present invention is proposed based on the first embodiment, and in this embodiment, before the step S20, the method further includes:
step S201, judging whether the initial speed is legal or not, and determining the motion track of the current object according to the initial speed when the judgment result is legal.
It should be noted that, since the initial speed may be synchronous data transmitted through the server, and the security of the synchronous data cannot be guaranteed, in this embodiment, before the synchronous data is processed, the validity of the synchronous data is determined, so that the security of the data is guaranteed.
It can be understood that the determining of the initial speed mainly includes two aspects, one is determining a format of the initial speed, and the other is determining a magnitude of the initial speed, and other ways of determining validity may also be included, which is not limited in this embodiment.
In a specific implementation, a data format and a speed size of the initial speed are obtained, and whether the data format is a preset format and whether the speed size is within a preset range are judged. Namely, judging whether the data format of the initial speed meets the requirement of a preset format, if not, indicating that the data of the initial speed is illegal data, not performing processing, and if so, indicating that the data of the initial speed is legal data, and then performing the next step.
Correspondingly, whether the initial speed is within a preset range or not can be judged, if the initial speed exceeds the preset range or does not meet the preset range, the data of the initial speed is represented as illegal data, the data are not processed, and if the initial speed meets the preset range, the data of the initial speed are represented as legal data, and the next step is executed. For example, if the detected acceleration data is 0, it indicates that the acceleration data is not valid data, and the processing is not performed.
In this embodiment, the synchronous data transparently transmitted by the server is processed, and the validity of the synchronous data is determined, so that the security of data transmission is ensured on the basis of improving the data transmission efficiency.
Further, as shown in fig. 7, a fourth embodiment of the collision synchronization method according to the present invention is proposed based on the first embodiment, the second embodiment and the third embodiment to explain based on the first embodiment, and in this embodiment, before the step S20, the method further includes:
step S202, judging whether the state of the current object meets a preset condition, when the state meets the preset condition, determining the motion track of the current object according to the initial speed, and judging whether the current object and other objects collide according to the motion track.
It should be noted that the meeting of the preset condition may be determining whether the current object is in a motion state, if not, recording is not required, and if the current object is in the motion state, calculating a motion trajectory of the current object, thereby improving calculation efficiency and calculation effectiveness.
In a specific implementation, speed information of a current object in a motion state is found out through data information sent by a server, a motion track of the current object is calculated through track calculation of the current object through the speed information, position information corresponding to corresponding time can be obtained through the motion track, and the current object is drawn through the position information.
The embodiment judges the current object in the current scene, judges each object in motion, and draws each object in motion through the initial speed, thereby reducing the calculation of the motion track of each object without position change and improving the system processing efficiency.
Further, as shown in fig. 8, a fifth embodiment of the collision synchronization method according to the present invention is proposed based on the first embodiment, the second embodiment and the third embodiment, so as to perform the description based on the first embodiment, and in this embodiment, after the step S30, the method further includes:
step S301, storing the target location information of the current object and the other objects in a preset storage area in a snapshot manner.
Further, the step S40 specifically includes:
step S401, extracting the position information of the snapshot record in the preset storage area to draw the current object and other objects, so as to implement collision synchronization.
Further, step S401 specifically includes:
step S402, acquiring preset time information, and searching two frames of picture information adjacent to the preset time in the preset storage area according to the preset time information.
It should be noted that, when the Cocos Creator editor updates the interface, the timed rendering can be performed through the Update function, and the time relative to the previous frame is introduced as a parameter. And updating the current timestamp for the relative time transmitted by the Update function according to the preset time information, and searching previous snapshot information and next snapshot information adjacent to the current timestamp in a preset storage area according to the updated current timestamp.
A schematic drawing flow diagram is shown in fig. 9. Wherein the time stamp refers to a relative time to a time when the drawing is initially started, calculates position information of a current time with respect to the time, and draws the scene according to the position information.
Step S403, calculating a motion ratio according to the preset time and the time information in the two adjacent frames of picture information.
In the present embodiment, the motion ratio is calculated by the formula: rate ═ where rate denotes the motion scale, frame1.timeoffset denotes the relative time of the frame before the current timestamp, and frame2.timeoffset denotes the relative time of the frame after the current timestamp.
Step S404, calculating target position information according to the motion proportion and the reference position information in the two adjacent frames of picture information, and drawing the current object and other objects according to the target position information to realize collision synchronization.
Target position information of the small ball is obtained by calculating x-axis and y-axis information of the ball by the formula (frame2.ball [ i ]. x-frame1.ball [ i ]. x) rate + frame1.ball [ i ]. x, ball [ i ]. y ═ (frame2.ball [ i ]. y-frame1.ball [ i ]. y) rate + frame1.ball [ i ]. y, where ball [ i ]. x represents x-axis coordinate information of the ith ball, ball [ i ]. y represents y-axis coordinate information of the ith ball, frame1.ball [ i ]. x represents x-axis coordinate information of a frame preceding the ith ball, and frame1.ball [ i ]. y represents y-axis coordinate information of a frame following the ith ball.
According to the embodiment, the position information corresponding to the current timestamp is calculated through the time ratio of the relative time to the current time and the position information corresponding to the relative time, so that each object in the current scene is drawn according to the current position information, and therefore collision synchronization is achieved.
Further, as shown in fig. 10, a sixth embodiment of the collision synchronization method according to the present invention is proposed based on the first embodiment, the second embodiment and the third embodiment, so as to be explained based on the first embodiment, in this embodiment, the step S40 specifically includes:
