Setting up the NetworkClient

1 - 3 minutes read


For simplicity, you are going to use the example LobbyScene included in the SWNetwork package for this tutorial.

The LobbyScene is located at Assets/SWNetwork/Scenes/LobbyScene.

The LobbyScene uses the JoinOrCreate() method to get players into rooms quickly. SWNetwork has a rich set of APIs to use for matchmaking. If you want to extend the matchmaking logic of your game further, please visit the Lobby API documentation.

Set up the NetworkClient

NetworkClient is the entry point of your game to interact with the SocketWeaver backend services. You must have one and only one NetworkClient active in your Scene.

In the LobbyScene hierarchy, select the NetworkClient GameObject. You will notice that a NetworkClient component is attached to it. NetworkClient has a few properties you can change. For now, you just need to configure its API_KEY property to get your game running.

Go to SocketWeaver Developer Portal, and create a new game.

Click the Copy button to copy the API key to your clipboard, paste it into the API_KEY textfield of the NetworkClient Component.

To test if everything is working correctly, you can play the LobbyScene. The game view should look like the screenshot below.

If you leave the custom playerId input field empty, LobbyScene will use a randomly generated unique playerId to check into the SocketWeaver services. The generated playerId will be stored in your computer's hard drive, so if you stop playing and play again, the same playerId will be used. The playerId is used to identify a client in the lobby servers and game servers.

By clicking the Register button, the LobbyScene sends a request to SocketWeaver, SocketWeaver will validate the API_KEY and route players to a lobby cluster that is geographically closest to them.

Once a player is connected to the assigned lobby cluster, the LobbyScene will automatically register the player to the lobby cluster. The Play button should replace the Register button now.

By clicking the Play button, the LobbyScene will try to find a room for the player or create a new room if it cannot find a room in the lobby cluster. By default, when a player is connected to the room's game server, the LobbyScene will load the scene at index 1. You can update it to load our Game scene.

    void HandleConnectedToRoom(bool connected)
        if (connected)
            Debug.Log("Connected to room");
            Debug.Log("Failed to connect to room");
