The server side does not need to compile and calculate the state of the game in real time, the design is general, and the load of the central node is high.
However, the client side has game logic, cheating is easy to realize by cracking the client side, and the safety is low.
2. State synchronization
The logic of the game is realized at the server, the client is similar to a presentation layer of the server data, the game operation initiated by the client is verified by the server, and meanwhile, the server updates the state of the game according to the game operation in real time and actively broadcasts the change data of the game state to the client for rendering and displaying.
Because the server side has the logic of the game, the cheating behavior needs to attack the server side, and the safety is higher.
However, the server needs to update the states of multiple games in real time, synchronization has delay, most of the states are accurate to the state of the previous frame, the load of the central node is high, the accuracy is low, the accuracy depends on the refresh frequency, and the pressure of the central node is increased due to the increase of the refresh frequency.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a game synchronization method according to an embodiment of the present invention, which is applicable to a case where a server and a client respectively possess game logic, and the server updates a game state in response to the client, where the game logic refers to preset game environments, game object attributes, game operation rules, and the like.
Furthermore, the embodiment is particularly suitable for small and medium-sized games with large concurrency and high requirements on instantaneity, interactivity and safety.
In one example, as shown in fig. 2A and 2B, in a game in which two users participate, each user has a certain score, and the user can control a chick to walk on a track, the chick can collide on the same track, if the chick reaches the bottom line, the opponent is deducted, and the score is deducted, i.e. the chick is lost.
In this example, the logic of the game includes a runway (environment), a category of the chicken (including weight, speed, etc.) (attributes of the game object), collision rules, deduction rules (run rules, etc.) of the chicken, and so on.
The method may be performed by a game synchronization apparatus, which may be implemented by software and/or hardware, and may be configured in a computer device, and the computer device may install a server (server), for example, a server, a workstation, and the like, and specifically includes the following steps:
s101, receiving an operation triggered in the game and sent by one of the clients.
In a specific implementation, the embodiment may be applied to a server, where the server is configured to maintain the state of the game in which at least two clients participate.
The client may be a browser, where the browser may load a page where a game is located, may also be an independent game application, may also be an applet or a plug-in the application, and the like, which is not limited in this embodiment.
After logging in an account at a client, a user can open a game with other users (represented by the client), and in the game, the user controls a game object to compete with the other users, wherein the game object can be a virtual character, a virtual machine (such as an airplane, a tank and the like), a virtual pet (such as a chicken and the like) and the like.
Further, the game may be a 2D game or a 3D game, which is not limited in this embodiment.
Taking a 2D game as an example, a 2D game, i.e., a two-dimensional game, can be interacted according to the needs of a user, and includes a horizontal version 2D game (i.e., a game screen is fixed in a horizontal direction) and may also include a vertical version 2D game (i.e., a game screen is fixed in a vertical direction).
In the present embodiment, each client owns the logic of the game, and updates the state of the game in real time at a preset refresh frequency (30 frames/sec).
When the client side triggers the operation in the game, the client side informs the server side of the operation, and relatively speaking, the server side can receive the operation which is sent by the client side and is triggered in the game.
In one case, the user's behavior triggers an action at the client that can be used to control a virtual character in the game, e.g., an action that can be used to place a chicken on a course, as shown in fig. 2A and 2B.
In this case, the server may receive an operation triggered based on the user behavior in the game, which is sent by one of the clients.
In another case, an action is automatically triggered during the running of the game, which can be used to change the user attributes in the game, e.g., as shown in fig. 2A and 2B, an action can be used to deduct the score of a user.
In this case, the server may receive an operation triggered in the game based on the user attribute, which is sent by one of the clients.
Of course, the above operations are only examples, and when the embodiment is implemented, other operations may be set according to actual situations, and the embodiment is not limited to this. In addition, besides the above operations, those skilled in the art may also adopt other operations according to actual needs, and this embodiment also does not limit this.
And S102, responding to the operation, and updating the state of the game.
The state of the game can be influenced by triggering operation in the game, namely when the operation is not carried out, the state in the game is predictable, the client can update the state of the game by itself when the client does not need to obtain key information, the server does not need to update the state of the game in real time, and the state of the game is updated immediately according to the predicted state when the operation of the client comes next time.
For example, as shown in fig. 2A and 2B, a chicken is at position x in the runway when the client triggers the last operation1The speed is v, and the client is at the position x in the runway when triggering the operation of the time t2＝x1+vt。
S103, verifying the legality of the operation according to the game state.
In the concrete implementation, the client updates the state of the game in real time according to the logic of the game, the triggered operation carries information representing the state of the game, the information is compared with the state of the game updated by the server, if the information is the same as the state of the game updated by the server, the operation is determined to be legal, the operation passes the validity check, and if the information is different from the game updated by the server, the operation is determined to be illegal and does not pass the validity check.
In one case, if the operation is used for a controlled virtual role, on one hand, the operation carries a role attribute of the virtual role, and then the role attribute of the virtual role controlled by the operation may be determined as a target role attribute.
On the other hand, the character attributes of the same virtual character are determined from the state of the game as the original character attributes.
In one example, the server determines a virtual character (e.g. chicken) according to the logic (e.g. probability, user level, etc.) of the game at the last operation time, the virtual character having specified attributes (e.g. weight, speed, etc.) of the chicken as a virtual character that the client can control at the local operation time, and updates the virtual character to the state of the game, and notifies the virtual character to the client so that the client can use the virtual character at the local operation time, at this time, the server can determine the virtual character determined at the last operation time and controlled at the current operation time from the state of the game, and determine the character attribute of the virtual character as the original character attribute.
Further, for the operation of the client, the server may determine a virtual character according to the logic (such as probability, user level, etc.) of the game in response to the operation, update the virtual character to the state of the game, and notify the client of the virtual character, the client being used for controlling the virtual character at the next operation.
Of course, the above manner of determining the original role attribute is only an example, and when the embodiment is implemented, other manners of determining the original role attribute may be set according to an actual situation, for example, the attribute of the virtual role is fixedly recorded in a database, and the like, which is not limited in this embodiment. In addition, besides the above-mentioned manner of determining the original role attribute, a person skilled in the art may also adopt other manners of determining the original role attribute according to actual needs, which is not limited in this embodiment.
And comparing the original role attribute with the target role attribute, and judging whether the original role attribute is the same as the target role attribute.
If the original role attribute is the same as the target role attribute, the virtual role controlled by the client can be determined to be the same as the virtual role controlled by the server, and the operation is determined to be legal.
If the original role attribute is different from the target role attribute, the virtual role controlled by the client is determined to be different from the virtual role controlled by the server, the client has the risk of being cracked, and the illegal operation is determined.
In another case, on the one hand, the state of the virtual character of the operation control in the game (such as the course where the chicken is located and its position) is determined as the target state.
On the other hand, the states of other virtual characters in the game (such as the runway and the positions of other chickens) are determined from the states of the game as original states.
And comparing the original state with the target state, and judging whether the original state conflicts with the target state.
And if the original state and the target state do not conflict, determining that the operation is legal.
And if the original state conflicts with the target state, determining that the operation is illegal.
In one example, the original state includes an original position of the virtual character in the game, and the target state includes a target position of the virtual character in the game, and in this example, the original position and the target position may be compared to perform collision detection.
And if the original position and the target position are mutually blocked, determining that the original state conflicts with the target state.
And if the original position and the target position are not mutually blocked, determining that the original state and the target state are not in conflict.
In yet another case, in one aspect, a user attribute of the operational change (e.g., a score of the user, a prop of the user, a virtual currency of the user, etc.) may be determined as the target user attribute.
On the other hand, the user attribute is determined from the state of the game as the original user attribute.
And comparing the original user attribute with the target user attribute, and judging whether the original user attribute is the same as the target user attribute.
And if the original user attribute is the same as the target user attribute, determining that the operation is legal.
And if the original user attribute is different from the target user attribute and the client has the risk of being cracked, determining that the operation is illegal.
Of course, the above validity checks are only examples, and when the embodiment is implemented, other validity checks may be set according to actual situations, which is not limited in the embodiment. In addition, besides the above validity check, a person skilled in the art may also adopt other validity checks according to actual needs, and this embodiment also does not limit this.
And S104, if the operation is legal, recording the operation into the game state, and maintaining the game state.
If the server side verifies that the operation of the client side is legal, the operation is recorded into the game state, namely, the operation is applied to the game to be effective, and when the subsequent client side synchronizes the game state, the operation can be synchronized.
Thereafter, for the game, the state of the game is maintained, that is, the state of the game at the server side is temporarily stopped, and the game is waited for updating by the next operation.
And S105, sending an operation confirmation message to the client.
And if the server side verifies that the operation of the client side is legal, sending a confirmation message to the client side, responding to the operation confirmation message by the client side, confirming that the operation is legal, and updating the state of the game in real time according to the operation.
And S106, synchronizing the operation to other clients.
And if the server side verifies that the operation of the client side is legal, synchronizing the operation to other client sides except the client side triggering the operation, wherein the other client sides are used for updating the state of the game in real time according to the operation.
In this embodiment, the server and the clients respectively have game logics, the server maintains the states of games in which at least two clients participate, if the server receives an operation triggered in a game and sent by one of the clients, the server can respond to the operation to update the states of the games, and performs validity check on the operation according to the states of the games, so as to ensure the security of the games and prevent the clients from being cracked, if the operation is legal, the operation is updated to the states of the games, and the states of the games are maintained, because the states of the games do not need to be updated in real time according to frames, the frequency of updating the states of the games can be greatly reduced, the load of the server as a central node is greatly reduced, the frequency of updating the states of the games within 1 second can reach 20-30 times, and for games with lower frequency of operation, the states of the games updated by hundreds of times can be reduced, the load reduction of the central node is obvious, in addition, the server side informs the current client side and other client sides to update the game state according to the operation, the normal operation of the game can be ensured, and the synchronization precision is high and can reach the millisecond level because the current state is returned by the server side.
In order to make those skilled in the art better understand the present embodiment, the operation synchronization, the state synchronization, and the passive state synchronization method in the present embodiment are compared below by taking the game shown in fig. 2A and 2B as an example.
The operation of the client can be divided into the operation triggered by the active user behavior (such as placing a chick in the track) as shown in fig. 2A and the operation triggered by the user attribute change (such as the chick cross-line deduction) as shown in fig. 2B.
For the user to place a chicken into the racetrack:
1. application operation synchronization
Each client records the number of the chickens on the competition field, the weight, the speed and other role attributes of each chicken, and respectively calculates the positions to which the current chickens move, whether collision occurs and other states in real time.
When a user places a chick to a runway, the client performs collision detection locally to judge whether the chick is blocked or not, if the chick is blocked, the client directly prompts the user that the chick is not placed, if the chick is not blocked, the user directly prompts the user that the chick is placed successfully, if the chick is not blocked, the user displays that the chick is placed successfully, the state of a local game is refreshed, and meanwhile, the operation of placing the chick to the runway is sent to the server.
The server serves as a transmitter of the operation of the client, simply records the operation, and then sends the operation to other clients participating in the game of the local game, and the other clients display the chick on the runway in the local game according to the operation.
In the synchronization mode, all the state updating and operation judgment are completed by the client, and the server only performs corresponding broadcast distribution during operation, so that the server has no great computational pressure in the game process, and has no great requirement on the performance of the server even if a large number of games are processed in parallel; however, the validity of the operation cannot be verified at the server, and when the client is cracked, the security of the game has great hidden trouble.
2. Application state synchronization
The server side pushes the positions of all the chickens in the game to the client side in real time at 30 frames/second to achieve smooth display.
When a user places a chick to a runway, when the client sends an operation of placing the chick to the runway to the server, the server compares the result of the calculation of the position of the chick in the previous game with the position of the chick placed at this time, if the result is not mutually blocked and the chick placed at this time is provided by the server, the server judges that the placement is successful, returns the successful result and the chick which can be placed at the next time to the client, and broadcasts the operation to other clients participating in the game of the local game to inform the clients of updating the state of the latest game.
Because the calculation result of the server is frequent, the time error is 1/30 seconds when the position comparison is carried out, the server self keeps the state of the current whole game, the attribute of whether the client illegally places or changes the chicken by self can be verified, the client refuses the game in illegal time, and the game is controllable and the safety is guaranteed; however, since the server needs to perform 30 calculations per game per second for smooth display, the load of the server is greatly increased.
3. Application passive state synchronization
Each client calculates the current game state in real time, when a user initiates the operation of placing the chicken to a certain runway, the client locally judges whether the obstacle exists or not according to the game state, if so, the client directly returns an error, and if not, the client initiates the operation to the server.
When the server receives the operation of the client, the server calculates the time difference between the last operation and the current operation, deduces the state of the current game according to the time difference, performs collision detection on the operation of the client and the state of the current game, records the timestamp of the current operation if the client is not in the interference state, broadcasts the operation to other clients participating in the game, and notifies the clients of updating the state of the latest game.
Because the operation of the user is not frequent, compared with thirty times per second calculation of state synchronization, the calculation can be ignored, meanwhile, because the operation of all the client sides is verified by the server side, the safety and controllability of the game are guaranteed, and because the calculation of the server side is not timed and quantitative, 1/30 second time error in the state synchronization is avoided, and the real-time performance is better.
And (3) for the cross-line deduction of the chickens:
1. application operation synchronization
The client calculates the state of the game in real time by itself, displays the corresponding state change to the user when triggering the deduction, and can also broadcast the operation of triggering the deduction such as the thread passing by the chick and the like to other clients to realize cheating operation.
2. Application state synchronization
The server side can calculate the state of the current game in real time, the operation of the deduction is broadcasted to each client side when the deduction is triggered, the client side does not calculate the operation of the deduction and the like, only the deduction operation sent by the server side is simply displayed, and the safety is high.
3. Application passive state synchronization
The client calculates the state of the game in real time by itself, the operation is sent to the server when the deduction is triggered, the server triggers calculation passively and broadcasts the verification result to other clients for displaying, and the client triggers the operation of checking the deduction by the server, so that the calculation amount is reduced while the safety is ensured.
Example two
Fig. 3 is a flowchart of a game synchronization method according to a second embodiment of the present invention, where the present embodiment further adds an illegal processing operation based on the foregoing embodiment, and the method specifically includes the following steps:
s301, receiving an operation triggered in the game and sent by one of the clients.
S302, responding to the operation, and updating the state of the game.
S303, carrying out validity check on the operation according to the game state.
S304, if the operation is illegal, rejecting the operation.
S305, synchronizing the state of the game to the client.
And if the server side verifies that the operation of the client side is illegal and the client side has the risk of being cracked, rejecting the operation of the client side, synchronizing the state of the game maintained by the server side to the client side, and applying the state of the game by the client side.
Generally, a server sends a synchronization notification to a client, and the client immediately responds to the synchronization notification to send a state synchronization request to the server and pull the state of a game from the server.
However, when the network environment is poor, there is a delay in the client responding to the synchronization notification, and at this time, the server receives the state synchronization request sent by the client, updates the state of the game in response to the state synchronization request, and synchronizes the updated state to the client.
EXAMPLE III
Fig. 4 is a flowchart of a game synchronization method according to a third embodiment of the present invention, where the present embodiment further adds a heartbeat and a restart processing operation based on the foregoing embodiments, and the method specifically includes the following steps:
s401, receiving an operation triggered in the game and sent by one of the clients.
S402, responding to the operation, and updating the state of the game.
S403, verifying the legality of the operation according to the state of the game.
S404, if the operation is legal, recording the operation into the game state, and maintaining the game state.
S405, sending an operation confirmation message to the client.
And the client is used for responding to the operation confirmation message and updating the state of the game according to the operation.
S406, synchronizing the operation to other clients.
And the other clients are used for updating the state of the game according to the operation.
