# GetObjectReferenceCurveBindings(AnimationClip)

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

## Definition

* **Type:** Method
* **Namespace:** [UnityEditor](/engine/6000.3/script-reference/unityeditor.md)
* **Assembly:** UnityEditor

```csharp
public static EditorCurveBinding[] GetObjectReferenceCurveBindings(AnimationClip clip)
```

### Parameters

**** (\[AnimationClip]\(/engine/6000.3/script-reference/unityengine/animationclip)): 

### Returns

| Type                                                                                        | Description |
| ------------------------------------------------------------------------------------------- | ----------- |
| [EditorCurveBinding\[\]](/engine/6000.3/script-reference/unityeditor/editorcurvebinding.md) |             |

### Remarks

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](/engine/6000.3/script-reference/unityeditor/animationutility/getcurvebindings.md) for float curves.

### Examples

```csharp
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);
            }
        }
    }
}
```
