IAnimationClipSource : how does it work?

Going through the release notes for 2018.3, I am trying to get examples working of all of the changes. I don't know how to get IAnimationClipSource to work.

Here is my naive example (just add clips to the list in the inspector):

Code (CSharp):

1. using UnityEngine;
2. using System.Collections.Generic;
3.  
4. public class AnimationClipPreviewer : MonoBehaviour , IAnimationClipSource{
5.     public List<AnimationClip> clipList;
6.     public void GetAnimationClips(List<AnimationClip> results) {
7.         results = clipList;
8.     }
9. }

Nothing shows up in the Animator window, yet it DOES trigger when the window is focused. How do we use this function?

 

results isn't an out parameter so reassigning it will do nothing. Try using results.AddRange(clipList).

 

Yep, that did it! I wonder if this is the intended way to use this, though.

 

What do you mean? If it worked then that's the way to use it. Your original way was wrong because of how C# works, not due to any odd quirk of Unity's system.

 

I mean if I'm supposed to keep a list of Animation clips or not. But you're right, if it works it works!
