[github-actions[bot]]

Description

A matchmaking system using with p2p and firebase.

Flow:

sequenceDiagram
    participant firebase
    host->>firebase: register as host in the pool
    client->>firebase: finds a host from the pool
    client->>host: connects to host
    host->>client: checks for enough players
    host->>firebase: remove itself from the pool
    host->>client: sends client to next scene
    host->>host: sends itself to next scene
    client->>host: disconnect and restart scene on connection timeout
    host->>host: subtracts client count upon client disconnection

How to use the extension

1.) Setup firebase config:

Requirements is a firebase account and a few tweaks:

1.a) Go to firebase project settings then get config then paste it in gdevelop settings (**important: don't forget to add double quotes to the keys **)

1.b) Enable anonymous login so users don't need to login to use the server

1.c) then finally enable realtime database, change its rules and use that as a prefix on the matchmaking action

2.) Call the match making action on your scene 3.) set how many number of players to be matched (minimum of 2) 4.) set where scene the host goes after enough players are matched 5.) set where scene the client goes after enough players are matched 6.) set the firebase prefix for the online lobby

7.) when everything is matched and on the next scene you can treat it as a normal p2p system 8.) there's also additional functions that can help you manage the online system such as shared variables and online sprites
