# totalVelocity

> The total velocity of the particle.

## Definition

* **Type:** Property
* **Namespace:** [UnityEngine](/engine/6000.5/script-reference/unityengine.md)
* **Assembly:** UnityEngine.ParticleSystemModule

```csharp
public Vector3 totalVelocity { get; }
```

### Remarks

This is calculated as the sum of [ParticleSystem.Particle.velocity](/engine/6000.5/script-reference/unityengine/particlesystem/particle/velocity.md) and [ParticleSystem.Particle.animatedVelocity](/engine/6000.5/script-reference/unityengine/particlesystem/particle/animatedvelocity.md). Some particle features use the physics-based velocity, and other features use the animated velocity. Use this property to obtain the total combined velocity of the particle.
