Master server

This script and scene is created to use multiple MultipleServer. The config is a json file in its root folder (with the exe).

{
    "Port": 5881,
    "Password": "***",
    "FPS": 60,
    "RefreshInterval": 120,
    "MaxInstanceNb": 50,
    "WaitingTimeout": 10,
    "ServersPsw": "MY STRONG PASSWORD",
    "ServersPort": 5882,
    "Servers": [
        "localhost"
    ]
}

• Port: Master server port (client connection)
• Password: Master server password (client connection)
• RefreshInterval: Interval of the hot refresh of the configuration file
• MaxInstanceNb: Limit the number of instances on the MultipleServer.
• WaitingTimeout: When a client is in the waiting list, if it do not call against in this interval, this party will be removed of the waiting list
• ServersPsw: Password of MultipleServers.
• ServersPort: MultipleServers port.
• Servers: MultipleServer address list.

Create a new game

Using SimpleNetMasterCmds.NewGame without arguments, master server returns a new unique ID (string). Save it on the client machine or on the client account.

Join a game

Using SimpleNetMasterCmds.JoinGame with the game ID in argument, master server try to create a new room on a MultipleServer and returns [true, address, port, password].

The game ID length must be > 10

If all servers are full, the game enter in the waiting loop. Master returns [false, position (int)]. Call this in a loop (with an interval of x seconds, this must be < WaitingTimeout) to create a wait routine.

If the game is already online, the master server returns [true, address, port, password].
