The LoadingView is a simple component. It works alongside the SceneTransitionManager, which can be extended with custom transitions. You can refer to the demo game samples to see it in action.

SceneTransitionManager

Loading Transition

Dictionary of transitions. Used by SceneLoader and SceneLoaderAddressable but you can also use it directly.

SceneTransition

An abstract class you can implement add to SceneTransitionManager.

csharp

public class SceneLoadTransitionFade : SceneTransition
{
	public float _fadeInDuration = 0.5f;
	public float _fadeOutDuration = 1f; // Longer because game lags when loading scene

	// Delay before scene loading starts
	public override float GetStartDelay()
	{
		return _fadeInDuration + 0.2f; // add some duration to make sure fade is complete before scene loading starts
	}
	public override void FadeIn()
	{
		SceneTransition.LoadingScreenToggleEvent?.Invoke(true, _fadeInDuration); // fade in, fade duration
	}

	public override void FadeOut()

		SceneTransition.LoadingScreenToggleEvent?.Invoke(false, _fadeOutDuration); // fade out, fade duration
	}
}
