Fig. 4 is a flow chart of a processing method of a multiplayer online game according to an embodiment of the present application. As shown in fig. 4, the method may be performed by a smart terminal, and the method includes the following steps S410 to S440.
Step S410: and acquiring a communication address of the appointed terminal, and establishing communication connection with the appointed terminal according to the communication address of the appointed terminal.
The designated terminal may be a game terminal in the established game network or may be a single game terminal. It should be noted that, the game terminals in the game network may also be referred to as game nodes, where one game node is responsible for data calculation and data synchronization of the entire game network, and may be referred to as a leader node.
The intelligent terminal starts the multi-player online game application and directly enters an offline map mode. Player 1 may input the IP address of player 2 (i.e., the designated terminal) at the game online interface of the smart terminal, so that the smart terminal obtains the communication address of the designated terminal, and may establish a communication connection with the designated terminal.
In another embodiment, the manner in which the intelligent terminal obtains the communication address of the specified terminal may be: player 2 shows player 1 a game two-dimensional code, player 1 scans the game two-dimensional code shown by player 2, and the game two-dimensional code can contain the IP address of player 2, so that the intelligent terminal corresponding to player 1 obtains the communication address of player 2 and is connected with the designated terminal corresponding to player 2.
In other embodiments, the terminal corresponding to the player 2 may view the "local IP address" on the game setting interface, and notify the player 1 to fill in, so that the intelligent terminal corresponding to the player 1 obtains the communication address of the specified terminal, and establishes communication connection with the specified terminal.
In other embodiments, each of the player 1 and the player 2 may register an account number on a third-party website, the third-party website maintains the IP of each player, and the third-party website may display the two-dimensional code or the IP of the other player by clicking a connection button, so that the intelligent terminal may establish a connection with the specified terminal through the communication address of the specified terminal provided by the third-party website.
Step S420: if the appointed terminal belongs to a game node of the constructed game network, acquiring a leader node address of the game network through the game node; wherein a plurality of game terminals participating in the same game office communicate with each other to form the game network; one of the game terminals is marked as a leader node of the game network.
It should be noted that, each game node in the game network stores a "node list", where the node list includes node information of each game node in the game network, where the node information may include a node name, a communication address, and an identifier of whether the node is a leader node. The leader node in the game network may be elected based on Raft algorithm. To distinguish, a game node other than a leader node (leader) may be referred to as a follower node (follower).
Normally there is only one leader node, the others are follower nodes. While the leader node will be responsible for all external requests, if not the leader node receives the request, the request will be directed to the leader node. Typically, the leader node will send a message, i.e., a "heartbeat," over a fixed time period, to let the follower node know that the leader node of the gaming network is still functioning. Each following node is designed with a timeout mechanism (timeout), and when no heartbeat (typically 150ms or 300 ms) is received for a certain period of time, the game network enters an election state, i.e. reelects a new leader node.
When the designated terminal belongs to a game node of a game network, the designated terminal sends a node list of the game network to the intelligent terminal, and the intelligent terminal can know which game node belongs to a leader node according to the node list to obtain a leader node address.
Step S430: and establishing communication connection with the leader node in the game network according to the leader node address.
In an embodiment, according to the leader node address, if the communication address of the specified terminal just coincides with the leader node address, that is, the specified terminal just is the leader node, then the communication connection with the specified terminal is established. If the appointed terminal is not the leader node, the intelligent terminal needs to establish communication connection with the leader node according to the address of the leader node.
And the leader node can provide a node list for the intelligent terminal, and the intelligent terminal establishes communication connection with all game terminals in the game network according to the node list provided by the leader node, so that the intelligent terminal joins the game network and becomes one of the game nodes. It should be noted that the node list is a data structure, such as an array/list/a direct. The node list on the leader node is always up to date, describing the latest "game net" overview, and the follower node can synchronize this node list to the local in time.
Step S440: and according to the game data sent to the game network by the leader node, synchronizing the game states with a plurality of game terminals in the game network.
The leader node is responsible for calculating game data, synchronizing game states in the game network, sending heartbeats at fixed time, maintaining a node list and the like. The game data includes the position, speed, orientation, whether two characters collide, who wins the game result, etc. of the character at each moment.
The leader node may transmit game data to each game node in the game network, so that each game node may receive the same game data, and synchronization of game states of game terminals in the game network is achieved. The game state refers to a state in which a character is located at a position, a speed, an orientation, whether or not collision occurs between two characters, who wins a game result, and the like at each time point presented by the game data.
According to the technical scheme provided by the embodiment of the application, the intelligent terminal can establish communication connection with the leader node through the communication address of any game terminal in the game network, the game terminal participating in the game is used as the leader node, game data are sent, and the synchronization of the game states of a plurality of game terminals in the game network is realized, so that the cost of purchasing a special server of a game provider, the electricity charge, the network charge and the maintenance cost are reduced, and the special server is not needed, so that single-point faults can be resisted.
In an embodiment, after the step S440, as shown in fig. 5, the method provided in the embodiment of the present application further includes: step S510-step S530.
Step S510: and receiving heartbeat signals sent by the leader node at fixed time.
For example, the leader node may send a heartbeat signal to all the following nodes in the game network every 100 milliseconds, which plays a role in notifying the following nodes that the leader node still works normally, and the following nodes may return a response message after receiving the heartbeat signal, thereby notifying the leader node that the node works normally. After the intelligent terminal joins the game network, the intelligent terminal can also receive the heartbeat signal sent by the leader node and return a response message.
Step S520: and if the heartbeat signal is not received in the preset time period, initiating a new leader node election process.
Since the leader node will send a heartbeat signal at a fixed time, if the intelligent terminal does not receive the heartbeat signal over time (e.g., 5 seconds), it indicates that the leader node is deactivated (e.g., disconnected from the network, shut down, or the game process/port is shut down). So that the intelligent terminal can initiate a new leader election process.
The process of initiating the new leader node election may be that the intelligent terminal sends a voting request to other nodes according to the node list (i.e. requests other nodes to cast a vote), and of course, the intelligent terminal may also cast a vote at the same time. After receiving the voting request of the intelligent terminal, the other nodes respond to acknowledge that the intelligent terminal is a new leading node. It should be noted that this request wait voting response has a validity period, for example, 500 ms, during which any node may request other nodes to vote on it.
If a certain game node receives N/2+1 votes within a valid voting period (where N is the length of the node list, i.e. the number of nodes in the game network, and deactivated nodes need to be excluded), the game node considers itself to be the leader node, and can inform other nodes that the game node is a new leader node, and the voting process is also finished. A heartbeat is started to be sent to other nodes periodically. If a game node receives the notification of the new leader node, the voting process is ended, the game node considers that the game node is a following node, and the heartbeat signal of the new leader node is received.
If this "voting validity period" is exceeded (e.g., 500 milliseconds), then a new round of voting continues to be reinitiated, letting the other nodes acknowledge themselves as the leader node. Until either the node itself is selected as the new leader node or other nodes are received as new leader nodes. Eventually a new leader node and follower node will be selected.
Step S530: and according to the selected new leader node, synchronizing the game states in the game network.
The new leader node may be the above-mentioned intelligent terminal which has just joined the game network, or may be a surviving game terminal which has already existed in the game network.
In one embodiment, if the own terminal (i.e., the smart terminal) is elected as the new leader node, the smart terminal calculates game data of the game office and synchronizes the game data to the game network.
It should be explained that synchronizing to the game network means transmitting game data to all surviving game terminals in the game network, so that the game data of all the game terminals in the game network are kept consistent, and synchronization of game states is achieved.
In an embodiment, since the intelligent terminal is elected as a new leader node, the intelligent terminal may also generate a new node list, synchronize the new node list to the gaming network, i.e., send the new node list to surviving gaming terminals within the gaming network. If a new node is added or exited, the intelligent terminal can update the node list and synchronize the updated node list to the game network.
In an embodiment, since the intelligent terminal is selected as a new leader node, the intelligent terminal can send heartbeat signals to the game terminals in the game network at regular time, so as to inform each game terminal that the terminal itself works normally, and determine which nodes are deactivated based on whether a response message is returned.
In contrast, in an embodiment, if the own terminal (i.e., the intelligent terminal) is not selected as the new leader node, the intelligent terminal may also receive the game data sent by the new leader node, and perform synchronization of the game states with the plurality of game terminals surviving in the game network. The intelligent terminal can also receive a new node list sent by the new leading node and heartbeat signals sent at fixed time.
In one embodiment, if the designated terminal in step S420 does not belong to the game node of the constructed game network. I.e. the designated terminal is also an isolated gaming terminal, the designated terminal together with the intelligent terminal may build a new gaming network. The intelligent terminal can mark a designated terminal as a leader node and form a game network together with the designated terminal; and according to the game data sent by the leader node (namely the designated terminal), synchronizing the game state with the leader node (namely the designated terminal). The designated terminal is used as a leading node and can also be responsible for the work of calculating game data, sending heartbeat signals, maintaining a node list and the like.
For example, both players start the game on their respective devices (cell phone/computer/tablet, etc.), enter the offline map mode directly, and become nodes. As shown in fig. 6-1, a player 1 fills in the IP address of a player 2 (designated terminal) in the game online interface of the intelligent terminal, so that the intelligent terminal (hereinafter referred to as node 1) is connected to the designated terminal (hereinafter referred to as node 2). As shown in fig. 6-2, node 1 is labeled Follower (following node) after connection, and node 2 is labeled Leader (Leader node, shown gray). At this time, the two nodes can play normally on-line, and a game network is formed. And carrying out complex calculation and synchronization states through the Leader node. The Leader node sends heartbeat signals at regular time, and the Follower node replies to each heartbeat signal.
As shown in fig. 6-3, if another node is not connected in the game, for example, the Follower node fails to receive the heartbeat signal sent by the Leader node at the timing (for example, every 100 ms) for a long time (for example, 5 seconds), or the Leader node fails to receive the reply of the heartbeat signal for a long time, the node 1 and the node 2 switch to the offline map mode respectively.
If node 3 is added (a new node is not on any game network at this time), it is assumed that node 3 is connected to Follower nodes, and the location of the Leader is known by Follower, as shown in fig. 6-4. As shown in fig. 6-5, assuming that node 3 is connected to the Leader node, the location of the Leader is known directly.
As shown in fig. 6-6, the newly added node 3 knows all node information in the game network and connects through the list of all nodes provided by the Leader node. Eventually all 3 nodes are interconnected. Complex computation/state synchronization may continue through the Leader node. After the complete connection, the new node 3 tells the Leader that the node is connected, the node list of the Leader is added by one, and then the node list is synchronized to all nodes in the game network.
6-7, If one of the Follower nodes (e.g., node 1) is deactivated or disconnected, follower node alone enters offline mode, the other nodes can still play normally, e.g., node 3 can still receive the heartbeat of the Leader node at a fixed time. The Leader node finds one less node, removes node 1 from the node list, and synchronizes the latest node list to node 3. The Leader continues to send heartbeat signals to all Follower nodes at regular intervals.
As shown in fig. 6-8, the Leader node is deactivated, the Follower node fails to receive the heartbeat of the Leader node for a long time, and the Follower node initiates Raft the election process (which may be initiated by node 1, may be initiated by node 3, and may be initiated simultaneously). Because node 1, node 3 are still connected and are aware of each other's original list of nodes, the new Leader is eventually selected. As shown in fig. 6-9, a node (e.g., node 3) is selected as the new Leader node, at which point the new game network has 2 nodes, node 1, node 3. Complex computation, state synchronization, sending heartbeat signals, node list maintenance, etc. are done by the node 3.
As shown in fig. 6-10 and fig. 6-11, the process of joining the 4 th node is the same as joining the 3 rd node, and the same is true for more nodes. The meaning of joining a new node is that there is a new player joining the game or that there is a new player switching from an offline map to an online map. The process of reducing nodes is the same as the deactivation (or communication) of a certain node. The meaning of reducing nodes is that a player drops a line for a long time or that the player switches from an online map to an offline map.
The foregoing is a description of a multiplayer online gaming method for a gaming network. The following describes how a plurality of online games of two game networks are combined into one game network, i.e., a process in which users participating in two game plays are combined into the same game play.
Assuming that the game network added by the intelligent terminal is a first game network, a second game network independent of the first game network exists. After the above step S440, as shown in fig. 7, the intelligent terminal may further perform the following steps S710 to S720.
Step S710: and selecting one leader node from the leader nodes of the first game network and the leader nodes of the second game network as a common node.
As shown in fig. 8, if there is no node connection between all nodes of the first game network and all nodes of the second game network, the first game network and the second game network are considered to be independent from each other.
Assuming that the leader node of the first game network is node 2 and the leader node of the second game network is node 22, the intelligent terminal may elect one node from among node 2 and node 22 as the leader node. All nodes in the first and second gaming networks may vote on node 2 and node 22. Assuming that the number of votes for node 2 is over half the voting period of validity, node 2 may be determined to be a common node. Conversely, if the number of votes from node 22 within the voting period of validity is over half, then node 22 may be determined to be a common node. The common node refers to a common leader node selected by all nodes in the first game network and the second game network.
In one embodiment, as shown in fig. 9, the step S710 specifically includes steps S711 to S713.
Step S711: and if a connection request of the designated node in the second game network is received, establishing communication connection with the designated node in the second game network.
The intelligent terminal is in the first game network, and the intelligent terminal can establish communication connection with the designated node on the assumption that the intelligent terminal receives the connection request of the designated node in the second game network. As shown in fig. 10, assuming that a player (node 21) finds that his friend is playing the game, node 21 may connect by entering the IP address of his friend (node 3) through an online interface, at which point node 3 may be considered an intelligent terminal, receiving a connection request from a designated node (node 21), establishing a communication connection with node 21. This time there is a conflict because there are two Leader nodes (node 2 and node 22) if the entire gaming network is connected to all nodes.
Step S712: and notifying the designated node of the leader node identification of the first game network, and receiving the leader node identification of the second game network provided by the designated node.
As shown in fig. 10, the intelligent terminal (node 3) may notify the designated node (node 21) that the leader node identifier of the first game network is node 2, and the node 21 may further notify the node 3 that the leader node identifier of the second game network is node 22, so that the intelligent terminal (node 3) may further receive that the leader node identifier of the second game network provided by the designated node is node 22.
Step S713: and electing the common node according to the leader node identification of the first game network and the leader node identification of the second game network.
Node 2 and node 22 may initiate Raft an election process. From the side of the intelligent terminal, the intelligent terminal can receive the voting requests sent by the node 22 and the node 2, and answer one of the voting requests (for example, the voting request of the node 2), so that the intelligent terminal selects the node 2 as a shared node.
Node 2 and node 22 initiate Raft an election process as follows: nodes 2 and 22 may initiate voting requests to all nodes of the first gaming network and all nodes of the second gaming network (requesting other nodes to vote themselves for 1 and1 at the same time), and other nodes may respond to the voting requests, i.e., approve that they be common nodes. If node 2 or node 22 receives N/2+1 votes (N being the total number of all nodes of the first and second gaming networks), i.e., more than half of the total number of nodes, once the votes received within a valid voting period (e.g., 500 milliseconds), then the votes are considered to be common nodes and all nodes are notified of the end of the vote.
Step S720: combining the first game network and the second game network to form a new game network; and the common node is used as a leading node of the new game network, and performs data synchronization in the new game network.
It should be noted that, before there is no result in the election, the node 2 is still responsible for the Leader function of the first game network, and the node 22 is still responsible for the Leader function of the second game network. Once the new result is available, a new game network is constructed in which all nodes are interconnected. The new game network has a unique Leader node.
For the intelligent terminal, communication connection with all nodes in a global node list can be established according to the global node list provided by the shared node; all nodes in the global node list are connected with each other to form the new game network.
The global node list includes information for all nodes in the first gaming network and the second gaming network. The shared node is used as a leader node of the first game network and the second game network, and has a latest node list of the whole network. The intelligent terminal can establish connection with all nodes of the first game network and the second game network according to the global node list issued by the common node. As shown in fig. 11, all nodes of the first game network and all nodes of the second game network establish a full connection relationship to constitute a new game network. Assuming that the elected common node is node 2, the node 2 is responsible for the calculation of game data of the new game network, state synchronization, heartbeat transmission and maintenance work of a node list.
It should be noted that the combination of a plurality of game networks and the combination of two game networks are similar. It is possible to merge one by one, for example, game net a with game net B into game net AB, then with game net C into game net ABC, then with game net D into game net ABCD. Or the game network A and the game network B can be combined into a game network AB, the game network C and the game network D can be combined into a game network CD, then the game network AB and the game network CD can be combined into a game network ABCD, and the leader node of the final election bears the work of the existing proprietary server.
In the MMO scene, a plurality of game nodes are connected with each other through the Internet, a game node is selected to serve as a Leader node through Raft algorithm in the initial stage, and complex calculation and state synchronization, such as the position/speed/orientation of a character at each moment, are completed through the Leader node, so that a game network is formed. Each following node detects whether the Leader node survives or not through a timing heartbeat mechanism, if the survival of the Leader node is not detected in a time-out mode, a new election is initiated, and a new Leader node is selected. When a new node a which does not belong to any game network joins the game network, a node b which is already in the network can be connected, the Leader node is known through the node b, and the node a is connected with the Leader node to synchronize information of other nodes of the game network. If the node in one game network X is communicated with the node of another game network Y, the election is reinitiated to form a larger game network.
Therefore, the technical scheme provided by the embodiment of the application can realize the multi-player online game without purchasing a special server, the relying calculation cost and the network cost are borne by the game node, and the cost of the game server is 0; the game node can be added/withdrawn at any time, the network has elasticity, and the capacity is expanded and contracted at any time; two or more gaming networks may be consolidated; the Leader node is faulty, so that a new Leader can be rapidly selected, the game network has robustness, and no single point fault exists.
