What is the best way to detect level load on additive/asnyc level loads

Questions & Answers

I basically want to duplicate the functionality of OnLevelWasLoaded(int level) but for these functions:
Application.LoadLevelAsync

Application.LoadLevelAdditive

Applicaiton.LoadLevelAdditiveAsync

In cases like this I use a LevelLoader which has events that get called. You declare your own events and then call them before and after the load event.

public delegate void LevelWillBeLoaded();
public delegate void LevelWasLoaded();

public static event LevelWillBeLoaded OnLevelWillBeLoaded;
public static event LevelWasLoaded OnLevelWasLoaded;

public void LoadLevel(string levelToLoad)
{
    StartCoroutine(LoadLevelCoroutine(levelToLoad));
}

IEnumerator LoadLevelCoroutine(string levelToLoad)
{
    if (OnLevelWillBeLoaded != null)
        OnLevelWillBeLoaded();
    yield Application.LoadLevelAsync(levelToLoad);
    if (OnLevelWasLoaded != null)
        OnLevelWasLoaded();
}
