Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, a flow chart of a game status synchronization method according to an embodiment of the invention is shown.
Specifically, the game state synchronization method comprises the following steps S1 to S3:
s1, acquiring a synchronous data packet sent by a client, and analyzing to obtain character state data of a target character;
s2, when the current picture frame of the target role exceeds a preset frame threshold critical point, calculating the role state data by adopting an interpolation algorithm, and synchronizing the state of the target role; the frame threshold critical point and the frame number difference value of the frame where the target character is born are preset difference values;
and S3, directly assigning and calculating the character state data when the current picture frame of the target character does not exceed a preset frame threshold critical point, and synchronizing the state of the target character.
Specifically, referring to fig. 2, fig. 2 is a diagram of a game status synchronization architecture provided in an embodiment of the present application, as shown in fig. 1, the game status synchronization architecture is composed of a service cluster 10 and a plurality of clients 20, and the present application is implemented by a local client, and performs game data synchronization between the local client and other clients. The client may be a computer, or may be a terminal device such as a mobile phone, which is not limited herein, and the data before the client and the client are broadcast through a server in a service cluster, so as to realize data synchronization.
For example, suppose user A, B, C, D, E five users are simultaneously online (each user represents a client) and moving arbitrarily within the same scene, at which time, if user a walks or runs in the scene, own state data, such as spatial coordinates/orientation, etc., is sent every T seconds. After the other four users receive the data sent by the user A, the state of the user A needs to be synchronized. Firstly, a user B needs to judge whether the image A is in a first frame image (namely, the image of the birth of the role A) in the image B, if so, the user A is directly assigned with the received data so as to avoid frame skipping or an erroneous interpolation process; if the frame is not the first frame, the interpolation motion is performed for the same T seconds to perform state synchronization, and similarly, the users C, D and E update the state of a in the respective frames to realize data synchronization of the respective users.
It should be noted that the preset difference is a positive integer greater than or equal to 0, and may be set according to practical situations.
Compared with the prior art, the embodiment of the invention reduces the risks of frame dropping, blocking and buffering in the character synchronization process by selecting different game state synchronization modes according to the comparison result of the current picture frame of the target character and the frame threshold critical point.
In a preferred embodiment, when the current frame of the target character exceeds a preset frame threshold critical point, an interpolation algorithm is adopted to calculate the character status data, so as to synchronize the status of the target character, and the method further includes:
acquiring the sending frequency of the client to the synchronous data packet;
and when the current picture frame of the target role exceeds a preset frame threshold critical point, carrying out interpolation operation on the role state data according to the sending frequency, and synchronizing the state of the target role.
For example, when a client receives data broadcast by a server, corresponding role synchronization is performed according to different data types, and it is assumed that other clients transmit data to the server at a transmission frequency of transmitting their own state data every T seconds, and the data is broadcast by the server. In the local client, when the character is larger than T, the character is reduced slowly and drifts when stopped; when the time is smaller than T, the role is locked in synchronization. In order to ensure that abnormal phenomena such as flash, jitter and delay can not occur to the character, frame accumulation calculation is started after a character birth instruction is received, the front M frames carry out direct assignment operation on data, so that the phenomenon of the character flash can be avoided, interpolation operation is carried out on the later data in the same T seconds, namely, the internal assignment is carried out on the data in the M frames, interpolation movement is carried out outside the M frames, and the smooth movement of the character without jitter and delay can be ensured.
It should be noted that, typically, M is set to a value that is not perceived by human eyes, for example, 10 frames, and may be set by the user according to the requirement, and is typically set to be within 15 frames, because the human eyes cannot perceive within 15 frames, and typically, the value of M may be set to be in the range of 1 to 15.
In a preferred embodiment, the acquiring the synchronization data packet sent by the client includes: and acquiring the synchronous data packet broadcast by the client through the server.
In a preferred embodiment, further comprising:
responding to user operation, processing the appointed role, and generating a synchronous data packet according to the processing result;
and broadcasting the generated synchronous data packet through a server and distributing the synchronous data packet to the client.
In a preferred embodiment, the processing of the designated character in response to a user operation includes at least one of:
responding to the role creation operation, and creating a designated role;
controlling the designated character to move in response to a character movement operation;
destroying the designated character in response to a character destroying operation;
and controlling the action state change of the designated character in response to the character action state change operation.
Specifically, the character creation operation, the character movement operation, the character destruction operation, and the character action state change operation are user operations, and the user can interact with the client through the electronic device such as a mouse, a keyboard, or a touch screen.
Specifically, different logic processes are respectively performed on the client and the server (server), and the client reports behavior data and analyzes synchronization behavior, and the server clusters process and pass-through behavior data, and the detailed flow is as follows:
first, the client needs to agree on a network synchronization data protocol with the server, which commonly includes, but is not limited to, role ID, message type, spatial location, spatial orientation, action instruction, and data corresponding to the action instruction, etc. After the protocol is defined, the client and the server respectively perform network synchronization logic development.
For clients, message types are classified into "character birth instructions" (birth instructions), "character movement timing update instructions" (timing update instructions), "character state change real-time update instructions" (state change instructions), and "character destroy instructions" (destroy instructions). When the character is initially created, the character birth data is required to be sent to a server; the method comprises the steps that when a character is in continuous movement, the character timing update data is required to be sent to a server every T seconds; when the role scene jumps or leaves and the like to be destroyed, a role destroy instruction needs to be sent to a server; when the action state of the character changes, new state data needs to be sent to the server in real time.
For the server, when receiving various types of data sent by the client, the sent data is directly transmitted and broadcast according to service requirements or broadcast after service processing, for example, when state change in a non-motion state of a role needs to be broadcast in real time, such as jumping, waving hands, sitting and other actions. Illustratively, as shown in fig. 3, the instruction data (synchronous data packet) sent by the client is parsed, and the effective scene ID and the instruction class (role state data) are identified, wherein the instruction class includes a birth instruction, a timing update instruction, a state change instruction and a destroy instruction; judging whether the birth place is required to be allocated for the birth instruction, if so, calculating the birth place, replacing data, performing data processing such as safety verification, behavior prediction and the like, and finally performing data broadcasting, and if not, directly performing data broadcasting; and carrying out data processing such as security verification, behavior prediction and the like on the timing update instruction, the state change instruction and the destroy instruction, and then carrying out data broadcasting.
And finally, when the client receives the data broadcast by the server, the corresponding role synchronization is still carried out according to different data types, and the game state synchronization method is adopted for synchronization.
In a preferred embodiment, further comprising:
initiating a role checking request to a server; wherein the character checking request comprises a current scene ID and the current character information of the current scene;
receiving character correction information fed back by the server, and correcting the character of the current scene according to the character correction information;
wherein the character correction information is obtained by the server by:
analyzing the role checking request to obtain the current scene ID and the existing role information;
inquiring all role information maintained by a background according to the current scene ID, and comparing the information with the existing role information to obtain missing roles and redundant roles;
and generating role correction information according to the missing roles and the redundant roles.
In a preferred embodiment, the character verification request further includes client heartbeat data, and the character modification information further includes server heartbeat data.
Specifically, frequent creation and removal of characters in a scene easily causes inconsistent numbers of characters, and in order to ensure consistent numbers of characters in the same scene, a client and a server correct by establishing a heartbeat mechanism. The client and the server judge whether the opposite side is offline or not by detecting the heartbeat information of the opposite side, and if the heartbeat is normally transmitted and received, the client and the server perform leak detection and defect repair through data. The specific process is as follows:
1. the client initiates a heartbeat format of { message type: heartbeat, data, scene ID, heartbeat information of all role information of the current scene. The message type is used for distinguishing the messages of other service layers, and the heartbeat data can be directly judged; the scene ID describes the unique identification of the scene where the client is currently located; all the role information of the current scene represents all the role information which the client can see in the current scene.
2. The heartbeat format initiated by the server is { message type: heartbeat, data: scene ID, to-be-added role list, to-be-deleted role list, after receiving the data sent by a certain client, the server can carry the data and make difference comparison with all the role information data of the scene maintained by the background to generate to-be-added role list and to-be-deleted role list, then form new heartbeat data and reply the new heartbeat data to the client.
3. After receiving the data sent by the server, the client creates missing roles and deletes redundant roles in the scene.
Therefore, in the game state synchronization method disclosed by the embodiment of the invention, the frame threshold critical point M is set, when the frame threshold critical point M is smaller than or equal to the threshold, direct assignment is adopted to carry out displacement synchronization, and when the frame threshold critical point M is larger than the threshold, an interpolation displacement mode is adopted to ensure that the character has no flash drift phenomenon; the method adopts a timing broadcast mechanism to reduce the data volume in the continuous displacement process of the roles without influencing the synchronization of the roles, and sends each piece of data to the service cluster in a timing way by T seconds during the continuous displacement, other clients perform interpolation displacement by the same T seconds, so that the roles can be ensured to have no jitter motion and no delay motion, and the problems of overlarge volume of the issued data, synchronous frame skip of the roles, stuck or slow behavior of the roles and the like are solved.
