# ParticleSystemShapeType

> The emission shape.

## Definition

* **Type:** Enum
* **Namespace:** [UnityEngine](/engine/6000.7/script-reference/unityengine.md)
* **Assembly:** UnityEngine.ParticleSystemModule

```csharp
public enum ParticleSystemShapeType
```

## Remarks

This is used by the [ParticleSystem.ShapeModule](/engine/6000.7/script-reference/unityengine/particlesystem/shapemodule.md) to determine how to sort the particles.
