Using Unity with Playroom Kit

Unity is the most popular game engine, it's also a great way to make web games thanks to the WebGL export option (opens in a new tab).

Playroom Kit complements Unity by simplifying the development of multiplayer games and interactive web-based applications.

Getting started

1. Install the SDK

The SDK is available as a Unity package. You can download the latest version from the releases page (opens in a new tab) (download playroomkit.unitypackage file).

To install, simply drag the package into your Unity project and import all files.

2. Initialize Playroom

The SDK can be initialized by calling PlayroomKit.InsertCoin in your game's Start method. You'll need to pass in a callback function that will be called when the host launches the game.

using Playroom;
// ...
 
void Start() {
    PlayroomKit.InsertCoin(() => {
        // The host has launched the game, you can start your game logic here.
    });
}

3. Set / Get game state

You can set and get the game state using the PlayroomKit.SetState and PlayroomKit.GetState methods. The game state is automatically synced with other players.

See the API reference for more information.

4. Export to WebGL

To export your game to WebGL, go to File > Build Settings and select WebGL as the platform. Then click Build and Run to export your game as a web page. Do note that Playroom Kit only works with WebGL builds.

Mock mode

Since the current SDK only supports Unity Web, we've introduced Mock mode - a way to test out your game's logic in Unity's Preview mode, without having to build for web every time. The mock mode doesn't connect to the Playroom server, instead it just mocks the API calls within Unity. This allows you to test out your game's logic without having to build for web every time.
