Using Rich Presence in Game

This how-to uses Rich Presence to send player status changes from your game.

Prerequisites

• Unity, Unreal, or Godot SDK installed and configured in your project (not required for REST).
• Rich Presence enabled in the Web Console.
• Presence enabled in the SDK.

Rich Presence

Rich Presence doesn't require any additional setup in the SDK.

Sending Status Changes

When sending a state change for a player, provide:

• A status name, e.g. main_menu, level_1, settings_menu.
• Metadata (optional), e.g. build_version, game_fps_count.

Unity

Sending a Presence status is as simple as calling a function.

// Example code of a function being called when the player enters a Game Over state
public void SendGameOverPresenceStatus()
{
    Dictionary<string, string> presenceDetails = new Dictionary<string, string>()
    {
        {"device", SystemInfo.deviceModel },
        {"unity_version", Application.unityVersion}
    };
    LootLockerPresenceManager.UpdatePresenceStatus("game_over", presenceDetails);
}

REST

Presence uses a WebSocket connection. First initialize a user session with REST using any of the authentication methods. Once authorized, open a WebSocket connection to ws://domain_key.lootlocker.com/game/presence/v1, with the first message being:

{"token": "the_signed_in_users_session_token"}

You'll get back a response confirming whether you were authenticated:

{"authenticated":true}

The WebSocket disconnects automatically after 1 minute of no activity. Send a ping once per minute to cover any network delays or interruptions — if the WebSocket disconnects, you'll need to reconnect.

{"type":"ping"}

Response:

{"type":"pong"}

To send Rich Presence statuses, send a message with the following structure:

{
    "metadata": {
        "key1": "value1",
        "key2":"value2"
    },
    "status": "game_status_to_send"
}

Out of Focus / Pause Behavior

When Auto Connect and Disconnect On Pause are enabled, Presence reconnects and resends the last status that was sent when Presence reconnects.
