## Definition

* **Type:** Property

* **Assembly:** UnityEngine.ParticleSystemModule

```csharp
public ParticleSystemColliderQueryMode colliderQueryMode { get; set; }

Use this option if you need to know which Colliders particles interacted with, inside the OnParticleTrigger callback.

Using it has an impact on performance, therefore it is disabled by default.
