This selects the space in which to simulate particles. It can be either world or local space.

Toggle between local and world space simulation using the following example:

public class ExampleClass : MonoBehaviour {

	private ParticleSystem ps;
	public bool useLocal = true;

	void Start() {
		ps = GetComponent<ParticleSystem>();
		var main = ps.main;
		useLocal = main.simulationSpace == ParticleSystemSimulationSpace.Local;
	}

	void Update() {
		var main = ps.main;
		main.simulationSpace = useLocal ? ParticleSystemSimulationSpace.Local : ParticleSystemSimulationSpace.World;
	}

	void OnGUI() {
		useLocal = GUI.Toggle(new Rect(10, 60, 200, 30), useLocal, "Use Local Simulation Space");
	}
}

Simulate particles relative to an independent game object using the following example:

		var main = ps.main;
		main.simulationSpace = ParticleSystemSimulationSpace.Custom;
		main.customSimulationSpace = relativeTo;
	}

	void Update () {
