# MinBounceIterations

> The fewest bounce passes a physics world runs in one simulation step.

## Definition

* **Type:** Field
* **Namespace:** [Unity.U2D.Physics](/engine/6000.7/script-reference/unity/u2d/physics.md)
* **Assembly:** UnityEngine.PhysicsCore2DModule

```csharp
public const int MinBounceIterations = 1
```

### Remarks

To stop shapes bouncing, set their bounciness to zero instead. See [PhysicsWorld.bounceIterations](/engine/6000.7/script-reference/unity/u2d/physics/physicsworld/bounceiterations.md), [PhysicsWorldDefinition.bounceIterations](/engine/6000.7/script-reference/unity/u2d/physics/physicsworlddefinition/bounceiterations.md) and [PhysicsShape.SurfaceMaterial.bounciness](/engine/6000.7/script-reference/unity/u2d/physics/physicsshape/surfacematerial/bounciness.md).
