# randomDirectionAmount

> Randomizes the starting direction of particles.

## Definition

* **Type:** Property
* **Namespace:** [UnityEngine](/engine/6000.6/script-reference/unityengine.md)
* **Assembly:** UnityEngine.ParticleSystemModule

```csharp
public float randomDirectionAmount { get; set; }
```

### Remarks

This accepts values from 0 to 1, where 0 causes the particles to retain their default direction and 1 causes a completely random direction. Values in between 0 and 1 blend the default shape direction with a random direction. This means that at 0.5, you get 50% of the default shape and 50% of a randomized direction.
