# addParticleSystem(_:transform:)

Attaches a particle system to the scene, using the specified transform.

## Declaration

```swift
func addParticleSystem(_ system: SCNParticleSystem, transform: SCNMatrix4)
```

```swift
func addParticleSystem(_ system: SCNParticleSystem, transform: SCNMatrix4)
```

## Parameters

- `system`: A particle system.
- `transform`: A transformation matrix that positions and orients the particle system relative to the world coordinate space of the scene.

## Discussion

Discussion A particle system directly attached to a scene is not related to the coordinate space of any node in the scene. To attach a particle system whose emitter location follows the movement of a node within the scene, use the corresponding SCNNode method. For details on particle systems, see SCNParticleSystem.
