# useTriggers

> Sets to filter contact results based on trigger collider involvement.

## Definition

* **Type:** Field
* **Namespace:** [UnityEngine](/engine/6000.3/script-reference/unityengine.md)
* **Assembly:** UnityEngine.Physics2DModule

```csharp
public bool useTriggers
```

### Remarks

Set to false to ignore any contacts involving trigger colliders. Set to true, to filter any contacts involving triggers and return such contacts.

**Note:** Contacts filtered by involved trigger colliders, are not filtered by the normal angles of the collisions, so [ContactFilter2D.useNormalAngle](/engine/6000.3/script-reference/unityengine/contactfilter2d/usenormalangle.md), [ContactFilter2D.minNormalAngle](/engine/6000.3/script-reference/unityengine/contactfilter2d/minnormalangle.md) and [ContactFilter2D.maxNormalAngle](/engine/6000.3/script-reference/unityengine/contactfilter2d/maxnormalangle.md) are ignored. Other active contacts will continue to be filtered by the normal angles of the collisions.
