SteamMultiplayerPeer for C#

This is an implementation of Godot's MultiplayerPeer (used by the high-level multiplayer API) using Steam for the underlying networking.

To use:

• Install the GodotSteam extension, or use their pre-compiled Godot binaries: https://github.com/GodotSteam/GodotSteam
• Install the GodotSteam C# bindings: https://github.com/LauraWebdev/GodotSteam_CSharpBindings
• Copy and paste SteamMultiplayerPeer.cs into your Godot C# project (e.g. /addons/steam-multiplayer-peer-csharp/SteamMultiplayerPeer.cs)
• Create an instance of SteamMultiplayerPeer and use the CreateServer/CreateClient methods as below:

    private const int VIRTUAL_PORT = 0;

    public void CreateServer() {
        var multiplayerPeer = new SteamMultiplayerPeer();
        var error = multiplayerPeer.CreateServer(VIRTUAL_PORT);

        if (error != Error.Ok) {
            GD.PrintErr("Error creating host: ", error);
            return;
        }

        Multiplayer.MultiplayerPeer = multiplayerPeer;
    }

    public void CreateClient(ulong steamId) {
        var multiplayerPeer = new SteamMultiplayerPeer();
        var error = multiplayerPeer.CreateClient(steamId, VIRTUAL_PORT);

        if (error != Error.Ok) {
            GD.PrintErr("Error creating client: ", error);
            return;
        }

        Multiplayer.MultiplayerPeer = multiplayerPeer;
    }
