# AnimationStream

> The stream of animation data passed from one Playable to another.

## Definition

* **Type:** Struct
* **Namespace:** [UnityEngine.Animations](/engine/6000.7/script-reference/unityengine/animations.md)
* **Assembly:** UnityEngine.AnimationModule

```csharp
public struct AnimationStream
```

## Remarks

The AnimationStream structure is passed through the animation [Playable](/engine/6000.7/script-reference/unityengine/playables/playable.md) structures, like [AnimationClipPlayable](/engine/6000.7/script-reference/unityengine/animations/animationclipplayable.md) and [AnimationMixerPlayable](/engine/6000.7/script-reference/unityengine/animations/animationmixerplayable.md). They can be modified when used with an [IAnimationJobPlayable](/engine/6000.7/script-reference/unityengine/animations/ianimationjobplayable.md), like the [AnimationScriptPlayable](/engine/6000.7/script-reference/unityengine/animations/animationscriptplayable.md).

The Playables implementing [IAnimationJobPlayable](/engine/6000.7/script-reference/unityengine/animations/ianimationjobplayable.md) take a custom C# job, which must implement [IAnimationJob](/engine/6000.7/script-reference/unityengine/animations/ianimationjob.md), and the AnimationStream is then passed to its callbacks during the animation processing pass.
