var particleSystems: [SCNParticleSystem]? { get }
```

## Discussion

An array of [`SCNParticleSystem`](/documentation/SceneKit/SCNParticleSystem) objects directly attached to the scene. This array does not include particle systems attached to nodes within the scene.

For details on particle systems, see [`SCNParticleSystem`](/documentation/SceneKit/SCNParticleSystem).
