AnimationUtility.GetObjectReferenceCurveBindings

설명

Returns all the object reference curve bindings currently stored in the clip.

Answers the question: "Which object reference properties are animated by the clip?".

Unity has two types of animation: Float and object reference. Float curve is a classic curve that animates float property over time. Object reference "curve" is a construct that animates object reference property over time.

This method returns only the object reference bindings. See AnimationUtility.GetCurveBindings for float curves.

using UnityEditor;
using UnityEngine;

// Editor window for listing all object reference curves in an animation clip
public class ClipInfo : EditorWindow
{
	private AnimationClip clip;

	[MenuItem ("Window/Clip Info")]
	static void Init ()
	{
		GetWindow (typeof (ClipInfo));
	}

	public void OnGUI()
	{
		clip = EditorGUILayout.ObjectField ("Clip", clip, typeof (AnimationClip), false) as AnimationClip;

		EditorGUILayout.LabelField ("Object reference curves:");
		if (clip != null)
		{
			foreach (var binding in AnimationUtility.GetObjectReferenceCurveBindings (clip))
			{
				ObjectReferenceKeyframe[] keyframes = AnimationUtility.GetObjectReferenceCurve (clip, binding);
				EditorGUILayout.LabelField (binding.path + "/" + binding.propertyName + ", Keys: " + keyframes.Length);
			}
		}
	}
