Hello,

Has anyone yet tried to extract all sprites that are used in a 2D Animator ? My goal is to do this in the Editor, by code. Anyone got a suggestion on how to do this ?
I jeed all the sprites used by all the animations inside a single Animator

Thanks,
T

Okay i figured out how to do it, so if anyone here is interested in this , there you go :

#if UNITY_EDITOR
	public static List<Sprite> GetSpritesFromAnimator(Animator anim)
	{
		List<Sprite> _allSprites = new List<Sprite> ();
		foreach(AnimationClip ac in anim.runtimeAnimatorController.animationClips)
		{
			_allSprites.AddRange(GetSpritesFromClip(ac));
		}
		return _allSprites;
	}

	private static List<Sprite> GetSpritesFromClip(AnimationClip clip)
	{
		var _sprites = new List<Sprite> ();
		if (clip != null)
		{
			foreach (var binding in AnimationUtility.GetObjectReferenceCurveBindings (clip))
			{
				ObjectReferenceKeyframe[] keyframes = AnimationUtility.GetObjectReferenceCurve (clip, binding);
				foreach (var frame in keyframes) {
					_sprites.Add ((Sprite)frame.value);
				}
			}
		}
		return _sprites;
	}
#endif

And then you can simply call GetSpritesFromAnimator(_anim) with your animator of choice as argument and you will get a list of Sprites back :slight_smile:
