# bounceCombine

> Determines how the effective bounciness is calculated when two Collider2D come into contact.

## Definition

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

```csharp
public PhysicsMaterialCombine2D bounceCombine { get; set; }
```

### Remarks

Defaults to [PhysicsMaterialCombine2D.Maximum](/engine/6000.3/script-reference/unityengine/physicsmaterialcombine2d/maximum.md) which allows either [Collider2D](/engine/6000.3/script-reference/unityengine/collider2d.md) to maximize bounciness. For example, a very bouncy ball always remains very bouncy.
