This tutorial module does not apply to WebGL builds due to limitations in Steamworks.

What's on the Menu​

For this module, you will use the LoginMenu_Starter that you configured in the previous Login with Device ID module. This menu consists of the following files:

  • LoginMenu_Starter: A C# class used to display the login menu.
    • C# file: /Assets/Resources/Modules/AuthEssentials/Scripts/UI/LoginMenu_Starter.cs
    • Prefab file: /Assets/Resources/Modules/AuthEssentials/Prefabs/LoginMenu_Starter.prefab

In the LoginMenu_Starter class, you will find the following button component. You will use this button to send a login request using single platform authentication, such as Steam:

[SerializeField] private Button loginWithSinglePlatformAuthButton;

Byte Wars will configure this button dynamically at runtime to display the single platform authentication login option. Since you will implement Steam as the single platform auth method, this button will be automatically bound to the following function in the SinglePlatformAuthWrapper_Starter class:

private void OnLoginWithSteamButtonClicked() { }

The SinglePlatformAuthWrapper_Starter class is a wrapper you will use to send the Steam platform token to log in to AGS. This process will be explained in more detail in the next section. The class is defined in the following file:

  • C# file: Assets/Resources/Modules/SinglePlatformAuth/Scripts/SinglePlatformAuthWrapper_Starter.cs

Ready the UI​

In this section, you will prepare the UI for the single platform authentication integration using Steam.

  1. Open the SinglePlatformAuthWrapper_Starter class and add the temporary code below to change the login menu to the loading state. You will later replace this with the actual login request.

    private void OnLoginWithSteamButtonClicked()
    {
        LoginMenu_Starter loginMenu = MenuManager.Instance.GetCurrentMenu() as LoginMenu_Starter;
        if (!loginMenu)
        {
            return;
        }

        loginMenu.OnRetryLoginClicked = OnLoginWithSteamButtonClicked;
        loginMenu.WidgetSwitcher.SetWidgetState(AccelByteWarsWidgetSwitcher.WidgetState.Loading);
    }

  2. Go back to the Unity Editor. Navigate to Assets/Resources/Modules/SinglePlatformAuth and open the SinglePlatformAuthAssetConfig.asset. Make sure the module is activated in Starter Mode by checking both the Is Active and Is Starter Active checkboxes.

  3. Return to the Unity Editor and play the game. You will see the Login with Steam button appeared.
