Scene loading

LoomUI persists across scene loads. The UI stays loaded while the game changes scenes.

Startup scene

Add LoomUI to a startup scene:

Tools > Loom > Setup UI in Current Scene

Start the game through this scene so Loom is initialized before other scenes try to use the bridge.

Per-scene drivers

A script in the loaded scene can update bridge state in Start():

public sealed class CombatUiDriver : MonoBehaviour
{
    private void Start()
    {
        UIBridge.Instance.CurrentScreen = GameScreen.Hud;
    }
}

Returning to menus

When loading a menu scene, set screen state the same way:

UIBridge.Instance.CurrentScreen = GameScreen.MainMenu;

Avoid destroying the Loom UI object just to change UI screens. Use bridge state and Solid rendering instead.

Loading progress

For loading screens, expose progress as bridge state:

public float LoadingProgress { get; set; }
public GameScreen CurrentScreen { get; set; } = GameScreen.Loading;

Assign LoadingProgress as the scene loads. The Solid loading screen can read that property to update its progress bar.
