public void Play ();
public void Play (bool withChildren);


withChildrenPlay all child Particle Systems as well.


Starts the Particle System.

Sets the Particle Systems into play mode and enables emitting (if it has been disabled).

If the Particle System has been paused, then this resumes playing from the previous time.
If the Particle System has stopped, then the system starts from time 0, and, if it is relevant, the startDelay is applied.

See Also: Stop, Pause, isEmitting functions.

The following example creates a GUI window for manipulating a Particle System.

using UnityEngine;

public class ParticleSystemControllerWindow : MonoBehaviour { ParticleSystem system { get { if (_CachedSystem == null) _CachedSystem = GetComponent<ParticleSystem>(); return _CachedSystem; } } private ParticleSystem _CachedSystem;

public Rect windowRect = new Rect(0, 0, 300, 120);

public bool includeChildren = true;

void OnGUI() { windowRect = GUI.Window("ParticleController".GetHashCode(), windowRect, DrawWindowContents,; }

void DrawWindowContents(int windowId) { if (system) { GUILayout.BeginHorizontal(); GUILayout.Toggle(system.isPlaying, "Playing"); GUILayout.Toggle(system.isEmitting, "Emitting"); GUILayout.Toggle(system.isPaused, "Paused"); GUILayout.EndHorizontal();

GUILayout.BeginHorizontal(); if (GUILayout.Button("Play")) system.Play(includeChildren); if (GUILayout.Button("Pause")) system.Pause(includeChildren); if (GUILayout.Button("Stop Emitting")) system.Stop(includeChildren, ParticleSystemStopBehavior.StopEmitting); if (GUILayout.Button("Stop &amp; Clear")) system.Stop(includeChildren, ParticleSystemStopBehavior.StopEmittingAndClear); GUILayout.EndHorizontal();

includeChildren = GUILayout.Toggle(includeChildren, "Include Children");

GUILayout.BeginHorizontal(); GUILayout.Label("Time(" + system.time + ")"); GUILayout.Label("Particle Count(" + system.particleCount + ")"); GUILayout.EndHorizontal(); } else GUILayout.Label("No Particle System found");

GUI.DragWindow(); } }
