How can i get a List<string> of all animations clips in Animation.animations ?

Unity Engine
1

I have added to a Camera a Animation component and changed the Animations size to 2. Added two clips.
Then in the script in the top:

Animation _animation;
List<string> animations = new List<string>();

In Start

private void Start()
    {
        _animation = GetComponent<Animation>();

        foreach (AnimationState state in _animation)
        {
           
            animations.Add(state.name);
        }
        int n = _animation.GetClipCount();
    }

But for some reason animations is empty count 0. But the variable n value is 2.
What i want to get all the Animations in the array.

I’m using unity 5.5.1f1 personal

The Animation component is a legacy component - you should only use it if you’re really sure you know what you’re doing, or are maintaining code that was written before its replacement existed.

Its replacement is Animator, and this information is available in that class via .runtimeAnimationController.animationClips

That said, I think the code you’re using should work as written - but if it’s a Unity bug, I doubt it’ll get fixed at this point.

Thanks found another way to do what i need without the Animation component at all. Sorry for the mess.

Start a new thread with your own situation and your own thread. It’s unlikely that this person’s exact workaround will be exactly like what you need for your situation, and more unlikely that they’ll come back and answer you 5 years after their post.

You’ve gotta tell us what the solution was when you get the solution please.

I can confirm it works with Unity 2021.2.8f1

I can’t find how to make the List or an Array visible in the inspector. and this is one of those things about Unity that is beyond infuriating…

But here’s how to get that array of names:

using UnityEditor;
using UnityEngine;

public class AnimControlLetter : MonoBehaviour {

    [SerializeField] private Animation _anim;
    [SerializeField] private AnimationClip[] _clips;
    [SerializeField] private int _clipCount;
    [SerializeField] private int clipToRun;
    public string[] _clipNames;

    void Start ( ) {
        if ( _anim == null ) _anim = GetComponent<Animation>(  );
        _clipCount = _anim.GetClipCount( );
        _clips = new AnimationClip[_clipCount];
        _clips = AnimationUtility.GetAnimationClips( this.gameObject );
        _clipNames = new string[_clipCount];
        for ( int i = 0; i < _clips.Length; i++ ) {
            _clipNames[i] = _clips[i].name;
        }
    }
}

here is a little script the will auto fetch all the clip names and add a button that will play the animation in play mode :

using System.Linq;
using UnityEngine;
#if UNITY_EDITOR
using UnityEditor;
#endif

public class AnimPlayer : MonoBehaviour
{
    public Animator animator;

    string currentState = "none";

    [HideInInspector] public string[] clips;

    private void OnValidate()
    {
        if( animator != null )
        {
            clips = animator
                .runtimeAnimatorController
                .animationClips
                .Select( x => x.name )
                .ToArray();
        }
    }

    private void Awake()
    {
        currentState = animator.GetCurrentAnimatorClipInfo( 0 )[ 0 ].clip.name;
    }

    public void Play( string newState )
    {
        if( ! Application.isPlaying ) return;

        if( currentState == newState ) return;

        animator.Play( newState );

        currentState = newState;
    }

    #if UNITY_EDITOR

    [CustomEditor(typeof(AnimPlayer))]
    class Inspector : Editor
    {
        int nextClip = 0;

        int[] intvalues;

        public override void OnInspectorGUI()
        {
            base.OnInspectorGUI();

            GUILayout.Space( 7 );

            var script = ( AnimPlayer ) target;

            intvalues = new int[ script.clips.Length ];

            for( var i = 0; i < intvalues.Length; ++ i ) intvalues[ i ] = i ;

            using ( new GUILayout.HorizontalScope() )
            {
                nextClip = EditorGUILayout.IntPopup( nextClip, script.clips, intvalues );

                if( GUILayout.Button("Play") )
                {
                    script.Play( script.clips[ nextClip ] );
                }
            }

        }
    }

    #endif
}

@Vladerx , you should note that this thread is a bit on the old side. And with that, it is also referencing the older legacy ‘Animation’ class not the contemporary ‘Animator’ class.

Yes i am aware , and here is one for the Animator class ( also works in edit mode ) , this one is a standalone animation clip player without the need to create animation controller asset , works with 2d sprites and 3d skinned mesh renderers
