ParticleSystem.MainModule.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()
    {
    }
}
