# AnimatableObjectChannels

> A set of named object reference channels that a script component exposes to the animation system.

## Definition

* **Type:** Class
* **Namespace:** [UnityEngine](/engine/7000.0/script-reference/unityengine.md)
* **Assembly:** UnityEngine.CoreModule
* **Implements:** [IEnumerable\<KeyValuePair\<string, Object>>](https://learn.microsoft.com/dotnet/api/system.collections.generic.ienumerable-1), [IEnumerable](https://learn.microsoft.com/dotnet/api/system.collections.ienumerable)

```csharp
public sealed class AnimatableObjectChannels : IEnumerable<KeyValuePair<string, Object>>, IEnumerable
```

## Remarks

Each channel holds a reference to a Unity object, such as a sprite. Animate the channels with object reference curves, in the same way as you animate the sprite of a [SpriteRenderer](/engine/7000.0/script-reference/unityengine/spriterenderer.md). Declare, name, and bind the channels in the same way as for [AnimatableFloatChannels](/engine/7000.0/script-reference/unityengine/animatablefloatchannels.md).

The following example exposes two channels and logs the objects they reference when an animation changes them.

```csharp
using UnityEngine;

public class PartSprites : MonoBehaviour
{
    // Animate these channels as "parts.Head" and "parts.Body".
    public AnimatableObjectChannels parts = new AnimatableObjectChannels();

    // Reset runs when you add the component in the Editor. The channel names are saved with the component.
    void Reset()
    {
        parts.SetChannels("Head", "Body");
    }

    void OnDidApplyAnimationProperties()
    {
        foreach (var part in parts)
            Debug.Log(part.Key + " uses " + (part.Value != null ? part.Value.name : "nothing"));
    }
}
```
