Remove all clips from animation by script

[Santa]

Hello,

How to remove all AnimationClips from Animation via script? The same as set Size in editor to 0 but from script. I'm trying do do so:

while ( animation.GetClipCount() > 0 )
    for (var state : AnimationState in animation) 
        if ( state )
        {
            animation.RemoveClip( state.clip );
            break;
        }

but the Unity crashes if there is a clip marked in editor as "None". Can't find out why is it so.

Is it another way? Or I'm doing something wrong?

How about this: (AnimationWipeArray.cs):

using UnityEngine;
//using System.Collections;

public class AnimationWipeArray : MonoBehaviour {

    void Start () {
        //for demonstration purposes, wipe out our animation as if we had changed the array size to 0 in the Inspector
        EmptyAnimationStateArray(gameObject);
    }

    void EmptyAnimationStateArray(GameObject go) {  
        if (!go.animation) return;

        WrapMode savedWrapMode = animation.wrapMode;
        bool savedPlayAutomaticallyState = go.animation.playAutomatically; 
        bool savedAnimatePhysicsState = go.animation.animatePhysics;
#if UNITY_3_0
        bool savedAnimateOnlyIfVisibleState = go.animation.animateOnlyIfVisible;
#endif

        //destroy the old
        DestroyImmediate(go.GetComponent(typeof(Animation)));
        //create the new
        Animation newAnim = (Animation)go.AddComponent(typeof(Animation));
        newAnim.wrapMode = savedWrapMode;
        newAnim.playAutomatically = savedPlayAutomaticallyState;
        newAnim.animatePhysics = savedAnimatePhysicsState;
#if UNITY_3_0
        newAnim.animateOnlyIfVisible = savedAnimateOnlyIfVisibleState;
#endif
    }

}

"None" usually indicates null object, IIRC, so maybe doing "if (state && state.clip)" would help?
