# GetSelfAndInterCollisionIndices(List<uint>)

> Get list of particles to be used for self and inter collision.

## Definition

* **Type:** Method
* **Namespace:** [UnityEngine](/engine/6000.5/script-reference/unityengine.md)
* **Assembly:** UnityEngine.ClothModule

```csharp
public void GetSelfAndInterCollisionIndices(List<uint> indices)
```

### Parameters

**** (\[List\<uint>]\(https\://learn.microsoft.com/dotnet/api/system.collections.generic.list-1)): List to be populated with cloth particle indices that are used for self and/or inter collision.

### Remarks

This allows you to access the cloth indices used for self and inter collision. The same set of indices is used in both situations if necessary. To enable self-collision, both self-collision distance and self-collision stiffness should be set to to non-zero values. To enable inter-collision, both inter-collision distance and inter-collision stiffness should be set to to non-zero values.
