public static EditorCurveBinding[] GetObjectReferenceCurveBindings(AnimationClip clip);

Description

Retrieves the object reference curve bindings stored in the animation clip.

Use this method to find which object reference properties are animatable.

Unity has two types of animation: float curve and object reference curve. A float curve is a classic curve that animates a float property over time. An object reference curve is a construct that animates an object reference property over time.

This method only retrieves the object reference curve 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); } } } }
