# rotationRandomness

> Apply randomness to the Force Field axis that particles will travel around.

## Definition

* **Type:** Property
* **Namespace:** [UnityEngine](/engine/6000.0/script-reference/unityengine.md)
* **Assembly:** UnityEngine.ParticleSystemModule

```csharp
public Vector2 rotationRandomness { get; set; }
```

### Remarks

When applying rotational forces to particles, the particles will spin around the Z axis of the Force Field's Transform component by default.

Using rotationRandomness allows each particle to deviate from this default axis by the specified amount. A value of 1 allows each particle to choose a completely random axis to spin around, whereas smaller values will constrain the movement more closely to the default axis.
