# ParticleSystem.TextureSheetAnimationModule

> Script interface for the TextureSheetAnimationModule.

## Definition

* **Type:** Struct
* **Namespace:** [UnityEngine](/engine/6000.0/script-reference/unityengine.md)
* **Assembly:** UnityEngine.ParticleSystemModule

```csharp
public struct ParticleSystem.TextureSheetAnimationModule
```

## Remarks

This module allows you to add animations to your particle textures. To author an animation, you must use a flipbook Texture.

![ParticleFlipbook (ParticleSystem.TextureSheetAnimationModule)](/api/media?file=/engine/6000.0/media/images/ParticleFlipbook.png)

*A flipbook texture sheet that contains eight sub-images of the numbers 1-8 across two rows of four columns. The first row contains the numbers 1-4 and the second row contains the numbers 5-8.*

Each numbered region represents a frame of the animation, which you must distribute evenly across the Texture. Select a variable below to see script examples. You may want to use this Texture on your Particle System with each example, to see how the module works.
