How to select an animation clip by index number?

I know this question is old, but I thought I'd share my fix.

I had 80 animated characters all with the same 5 animations, though some of them were named differently because it would be the walk cycle for a crawling baby or an old man with a walking stick, therefore different from the walk cycle of my generic humans.

What I did was create a script that just had a variable for animationClips.

 var animList : AnimationClip[];

That's it, that's all my script had lol. Then I applied it to the prefabs of all my 80 chars, and listed their animations in respective order:

bind walk flinch dance suicide

Then in script I just said

 gameObject.animation.Play(getComponent(AnimList).animList[0]);

basically I couldn't access THEIR array so I made my own array that I COULD access.

I believe you can't, stupid, isn't it? You CAN however iterate over the animationclips with the (in C#) foreach keyword:

foreach (AnimationClip clip in animation) {
    // do initialisation or something on clip
}

Kind of simple, but if it saves someone some time...

 string ClipIndexToName(int index)
 {
     AnimationClip clip = GetClipByIndex(index);
     if (clip == null)
         return null;
     return clip.name;
 }

 AnimationClip GetClipByIndex(int index)
 {
     int i = 0;
     foreach (AnimationState animationState in animation)
     {
         if (i == index)
             return animationState.clip;
         i++;
     }
     return null;
 }

Update, since the above seems to have broke with Unity 5 (or maybe was always fragile and now I'm just finding out), I ended up changing GetClipByIndex to this. Too bad I have to hard-code the clip names, a little extra work:

 AnimationClip GetClipByIndex(int index)
 {
     string[] ClipNames = { "StepForward", "StepBackward", "ShortThrow", "LongThrow", "BackwardThrow", "SoftThrow", "Bull", "Hurt" };
     Animation animation = GetComponent<Animation>();
     return animation[ClipNames[index]].clip;
 }

Animations in Array: Someone has tried to make a unique class to attach to the gameobject you're animating. I can't get it to work, but I understand the idea ..... I think. Anyway here is the thread: http://forum.unity3d.com/threads/64262-Animation-clips-in-array-!!?highlight=animation+clip+index

Here is the way to index AnimationClips or AnimationStates as they are called:

     GameObject goPlayer = ... some object with animation
 
     int animCount = goPlayer.animation.GetClipCount(); // clip?! Unity people, why not state??
     Debug.Log("Animations found: " + animCount );
     
     int idx=0;
     foreach (AnimationState anim in goPlayer.animation) 
     {
         // show me my animation name!!!
         Debug.Log("Animation ("+ idx +"): " + anim.name);
         idx ++;
     }
