Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, 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 some embodiments of the present application, but not all embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. 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.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

In the network game, for the action type network game, generally, the requirement of the player on the immediate feedback of the operation of the game is very strict, and an intuitive solution is to make client-side prediction (client-side prediction), that is, the client side precedes.

The client is divided into three types according to the state of the virtual role in advance: move first, execute first, settle first. The moving position of the virtual role is updated in advance at the client in advance without waiting for being issued by the server; the application method firstly judges and updates the feasibility and the expression effect of the virtual character application in advance at the client side without waiting for the state of the application method issued by the server side; the settlement is firstly the damage settlement caused by virtual character attack, and is predicted and simulated in advance at the client side without waiting for the damage settlement issue of the server side. It can be understood that, although the three precedent are all the client locally predicting in advance, the subsequent receiving of the state issued by the server still needs to mediate (reconcile) the local state and the server calibration state, so as to balance the client performance effect and the real logic state.

Generally, in game development, the mobile advance is more practically applied to a client side than the implementation advance and the settlement advance, because the implementation advance and the settlement advance have a difference between existence and nonexistence once prediction fails, and if state rollback is performed, experience is poor; even if the prediction fails in the prior movement, the movement is only the error of the virtual character position, so a reasonable balancing scheme is as follows: client moves ahead, and administration and settlement depend on the determination of the server. However, the conventional synchronization method has a problem that the positions of the virtual characters in the client and the server are not synchronized.

In view of this, the embodiment of the present application provides a method for synchronizing actions in a game, which can ensure synchronization of virtual character positions between a game client and a server, and improve game experience.

Fig. 1 is a flowchart of a method for synchronizing actions in a game according to an embodiment of the present application, where the method may be applied to a game client, where the game client may be installed on a game client device such as a mobile terminal, a computer, a handheld computer, and the like, and the game client device may store a game program and be used to present a graphical user interface, where the graphical user interface includes a game screen, and the game screen may present a virtual Character and a Non-Player Character (NPC), such as a virtual pet and a virtual sprite, controlled by a Player. As shown in fig. 1, the method may include:

s101, acquiring target position data issued by a server, wherein the target position data comprises: and issuing a timestamp, position information of the virtual role and a frame interval.

For the frame interval, different parameters, such as 1/30ms, 1/60ms, etc., may be corresponded according to different application scenarios, and the application is not limited herein.

In some embodiments, the target location data may be location information predicted by the server according to the current frame data, or may be location information predicted according to the historical frame data, which is not limited herein. The game client can correct the position information of the virtual character by acquiring the target position data, so that the synchronization of the positions of the virtual character in the game client and the virtual character in the server is realized.

The current position information of the virtual character is the position information predicted by the game client according to the current frame data, so that the response speed of the movement of the virtual character in the game client to the operation of the rocker can be increased under a high-delay network environment, and the game experience is improved.

It can be understood that, when the game client acquires the target position data issued by the server, the local position calibration parameter can be acquired according to the target position data and the current position information of the virtual character, and the local position calibration parameter can be used for calibrating the position of the virtual character on the basis of the current position information of the virtual character, so as to achieve synchronization of the positions of the virtual character in the game client and the server.

S103, calibrating the current position information of the virtual character according to the local position calibration parameters, and acquiring the position information of the virtual character after calibration.

Optionally, the local position calibration parameter may correspond to a position calibration vector, and for the game client, the game client may calibrate the current position information of the virtual character according to the local position calibration parameter obtained by the calculation, that is, may calibrate based on the current position information of the virtual character predicted by the game client, so as to implement smooth rollback. In some optional embodiments, the current position of the virtual character may be added to the position calibration vector corresponding to the local position calibration parameter, so as to obtain the position of the virtual character after calibration, but not limited thereto.

For example, assume that the current location information of the virtual character is P_AThe local position calibration parameter is P_BIn some embodiments, the virtual character calibrated position information may be P_c＝P_A+P_BHowever, the actual updating mode is not limited to this, and the virtual character updating method can be flexibly set according to the actual application scenario, so that the position information of the virtual character calibrated in the game client can be kept consistent with the position information of the virtual character calculated in the server, and the synchronization of the virtual character positions between the game client and the server is ensured. It can be understood that, because calibration can be performed based on the current position information of the virtual character predicted by the game client during calibration, for the game client, when the position of the virtual character in the game client is updated and expressed, a pulling feeling caused by synchronization can be reduced during the expression process, and player experience is improved.

Optionally, as shown in fig. 2, the obtaining a local position calibration parameter according to the target position data and the current position information of the virtual role includes:

s201, obtaining a history rocker operation queue.

The rocker operation queue comprises: historical rocker information in the historical duration, historical timestamps corresponding to the historical rocker information and frame intervals are preset.

The history rocker operation queue in the game client may be configured to store related information of history rocker operation in a certain time period, for example, the history rocker operation queue may include history rocker information in a preset history time period, a history timestamp corresponding to the history rocker information, and a frame interval, and according to an actual application scenario, the preset history time period may be: 1 minute, 2 minutes, 5 minutes, etc., which are not limited herein, and certainly, the number of the historical joystick messages in the preset historical time period is not limited, and alternatively, the number of the historical joystick messages may be 5, 10, etc., which are not limited herein.

And S202, acquiring the deduction position information according to the historical rocker operation queue and the target position data.

Optionally, when the derived position information is obtained, position derivation may be performed sequentially according to the time sequence with the target position data as a starting point according to the historical rocker operation queue to obtain a new position, and the position information corresponding to the new position may be recorded as the derived position information.

For example, the history rocker operation queue includes history rocker information X1, history rocker information X2, and history rocker information X3, and the corresponding timestamps thereof are, respectively, T1, T2, and T3, and T3> T2> T1, that is, history rocker information X1 corresponding to T1 is stored first, history rocker information X3 corresponding to T3 is stored latest, and target position data P1 is position information corresponding to history rocker information X1, so that the game client may obtain the derived position P according to a local derived algorithm. Alternatively, the derived position P may be represented as P-P1 + X2 + X3, although the derived manner is not limited thereto according to the actual application scenario.

And S203, acquiring local position calibration parameters according to the current position information and the derived position information of the virtual role.

And S303, if the position difference value is larger than a second preset threshold value, acquiring local position calibration parameters according to a second preset calibration algorithm.

When calculating the local position calibration parameter, the calibration may be performed according to a position difference between the current position information and the derived position information of the virtual character, optionally, the position difference may be compared with a first preset threshold and a second preset threshold, whether to perform the position calibration is determined according to a comparison result, and how to obtain the local position calibration parameter when performing the position calibration.

Optionally, the local position calibration parameter may be represented by a position calibration vector, and if the position difference is smaller than a first preset threshold, the position calibration vector may be made to be a zero vector, which indicates that position calibration is not required; if the position difference is greater than a preset first preset threshold and smaller than a second preset threshold, a position calibration vector may be obtained according to a first preset calibration algorithm, for example, the position calibration vector is equal to a preset moving speed v of the virtual character x frame interval dt x a fixed coefficient r 1; if the position difference is greater than the second preset threshold, a position calibration vector may be obtained according to a second preset calibration algorithm, for example, the position calibration vector is the position difference D × the fixed coefficient r 2. The value of the fixed coefficient r2 may be greater than the fixed coefficient r1, and in some embodiments, r1 may be any value between 0 and 0.2, so that the local position calibration parameter calculated according to the first preset calibration algorithm may be used for fine tuning of the virtual character position; r2 can take a larger value (for example, any value between 1 and 2), so that the local position calibration parameter calculated according to the second preset calibration algorithm can cope with special conditions, and the forced rollback of the virtual role position is realized, and the values of r1 and r2 are not limited in the application, and can be flexibly set according to the actual application scene; for the preset moving speed v of the virtual character, it may be different according to different game scenes, for example, according to the game level of the player, when the game level is higher, the preset moving speed v of the virtual character may be larger, and when the game level is lower, the preset moving speed v of the virtual character may be smaller, but not limited thereto; for the frame interval, it may also be different according to different game scenes, for example, the 30 frame rate game frame interval is 1/30ms, i.e. about 33.3 ms; the game frame interval for the 60 frame rate is 1/60ms, i.e., approximately 16.7 ms.

The historical rocker information and the frame interval stored in the historical rocker operation queue can be obtained, and the first time difference can be calculated in different modes according to different quantities of the historical rocker information. Optionally, if the number of the historical rocker information is equal to 1, that is, the historical rocker information only includes current rocker information corresponding to current frame data, the frame interval may be used as a first time difference (that is, a time difference between the current frame data and previous frame data); and if the number of the historical rocker information is greater than 1, the historical rocker operation queue also comprises other historical rocker information besides the current rocker information corresponding to the current frame data, the time difference between the historical time stamps corresponding to two continuous historical rocker information in the historical rocker operation queue can be calculated, and the minimum time difference is taken as the first time difference.

The historical time difference between the historical time stamp corresponding to each piece of historical rocker information in the historical rocker operation queue and the time stamp in the position data corresponding to the current frame data can be calculated, the minimum time difference is used as a second time difference, and the historical rocker operation queue is updated according to the first time difference and the second time difference.

s601, obtaining historical rocker information corresponding to the second time difference, and marking a historical time stamp corresponding to the historical rocker information as a reference time stamp.

S602, deleting the historical rocker information of which the time stamp is less than or equal to the reference time stamp in the historical rocker operation queue, and acquiring the updated historical rocker operation queue.

The historical rocker information corresponding to the second time difference, that is, the time difference between the historical timestamp corresponding to the historical rocker information and the issuing timestamp corresponding to the current frame data is the smallest, and for the historical rocker information, the historical timestamp corresponding to the historical rocker information can be marked as a reference timestamp.

For example, the historical rocker operation queue includes historical rocker information X1, historical rocker information X2, and historical rocker information X3, and the corresponding timestamps thereof are T1, T2, and T3, respectively, and T3> T2> T1, that is, historical rocker information X1 corresponding to T1 is stored first, historical rocker information X3 corresponding to T3 is stored latest, the issue timestamp corresponding to the current frame data is TX, if it is determined through calculation that the time difference between timestamp T2 and timestamp TX is minimum, then timestamp T2 may be recorded as a reference timestamp, and historical rocker information X2 is historical rocker information corresponding to the second time difference.

Based on the above embodiment, the historical rocker information with the timestamp less than or equal to the reference timestamp in the historical rocker operation queue can be deleted, so that the historical rocker information with the earlier historical timestamp in the historical rocker operation queue can be deleted, and the updated historical rocker operation queue can be obtained.

and if the current frame data is determined to include the rocker information, adding the current rocker information corresponding to the current frame data into the historical rocker operation queue.

It can be understood that, for the game client, the game client generates current frame data, and if it is determined that the current frame data includes the rocker information, the current rocker information corresponding to the current frame data may be added to the historical rocker operation queue, so that when new rocker information is generated, the new rocker information may be stored through the historical rocker operation queue.

and S901, acquiring the direction of a rocker according to the rocker information included in the current frame data.

S902, adjusting the orientation of the virtual character according to the current orientation, the rocker direction, the frame interval and the preset turning angular speed of the virtual character.

The direction of the rocker corresponding to the rocker information can be obtained according to the rocker information included in the current frame data, the direction of the virtual character can be adjusted according to the direction of the rocker, the current direction of the virtual character, the frame interval and the preset turning angular velocity of the virtual character, and the direction of the adjusted virtual character is obtained, so that the response speed of the turning of the virtual character in the game client to the rocker can be improved under a high-delay network environment, and the instant response is realized. The preset turning angular velocity (i.e., turning speed) of the virtual character may be different according to different application scenarios.

Optionally, the adjustment may be performed by taking the direction of the joystick as OT, the current orientation of the avatar as OS, and the orientation of the adjusted avatar may be min (OT-OS, the preset turning angular velocity w of the avatar x the current frame time interval dt), that is, the minimum value between the two values; in addition, it should be noted that, if the current frame data does not include the rocker information, the value of OT may be the rocker direction corresponding to the last rocker information of the game client, and the orientation of the adjusted virtual character may be obtained by using the same calculation process.

Optionally, the method further includes:

if the current frame data is determined to include rocker information, setting the motion state of the virtual character as a moving state; or if the current frame data does not comprise the rocker information, setting the motion state of the virtual character as a stop state.
