public ParticleSystemSimulationSpace simulationSpace;

Description

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:

#pragma strict
private var ps: ParticleSystem;
public var useLocal: boolean = true;
function Start() {
	ps = GetComponent.<ParticleSystem>();
	var main: var = ps.main;
	useLocal = main.simulationSpace == ParticleSystemSimulationSpace.Local;
}
function Update() {
	var main: var = ps.main;
	main.simulationSpace = useLocal ? ParticleSystemSimulationSpace.Local : ParticleSystemSimulationSpace.World;
}
function OnGUI() {
	useLocal = GUI.Toggle(new Rect(10, 60, 200, 30), useLocal, "Use Local Simulation Space");
}
using UnityEngine;
using System.Collections;

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:

#pragma strict
public class ParticleSystemScript extends MonoBehaviour {
	private var ps: ParticleSystem;
	public var relativeTo: Transform;
	function Start() {
		ps = GetComponent.<ParticleSystem>();
		var main: var = ps.main;
		main.simulationSpace = ParticleSystemSimulationSpace.Custom;
		main.customSimulationSpace = relativeTo;
	}
	function Update() {
	}
}
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ParticleSystemScript : MonoBehaviour { private ParticleSystem ps; public Transform relativeTo;

void Start() { ps = GetComponent<ParticleSystem>();

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

void Update() { } }
