# shape

> Script interface for the ShapeModule of a Particle System.

## Definition

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

```csharp
public ParticleSystem.ShapeModule shape { get; }
```

### Remarks

Configures the initial positions and directions of particles.

Particle System modules do not need to be reassigned back to the system; they are interfaces and not independent objects.

### Examples

```csharp
using UnityEngine;
using System.Collections;

[RequireComponent(typeof(ParticleSystem))]
public class ExampleClass : MonoBehaviour {
    public Mesh myMesh;

    void Start() {
        ParticleSystem ps = GetComponent<ParticleSystem>();
        var sh = ps.shape;
        sh.enabled = true;
        sh.shapeType = ParticleSystemShapeType.Mesh;
        sh.mesh = myMesh;
    }
}
```
