## Definition

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

```csharp
public static int GetSafeTriggerParticlesSize(this ParticleSystem ps, ParticleSystemTriggerEventType type)
```

### Parameters

**** (\[ParticleSystem]\(/engine/6000.5/script-reference/unityengine/particlesystem)): Particle system.**** (\[ParticleSystemTriggerEventType]\(/engine/6000.5/script-reference/unityengine/particlesystemtriggereventtype)): Type of trigger to return size for.

### Returns

| Type                                                       | Description                                       |
