描述

Callback invoked when the first scene's objects are loaded into memory but before Awake has been called.

For more info on ordering see RuntimeInitializeOnLoadMethodAttribute.

// Demonstration of the RuntimeInitializeLoadType.BeforeSceneLoad attribute to find inactive objects before Awake has been 
// called for the first scene being loaded. Then from these inactive objects we find which ones will be active after Awake is called later.
using UnityEngine;

Will be Active after Awake, count: " + willBeActiveAfterSceneLoad); }
