Well, you can also set EditorApplication.isPlaying ;)

edit
Since there were complaints that "EditorApplication" can't be used in runtime scripts, here's how you can use it:

 //C#
 public static class AppHelper
 {
     #if UNITY_WEBPLAYER
     public static string webplayerQuitURL = "http://google.com";
     #endif
     public static void Quit()
     {
         #if UNITY_EDITOR
         UnityEditor.EditorApplication.isPlaying = false;
         #elif UNITY_WEBPLAYER
         Application.OpenURL(webplayerQuitURL);
         #else
         Application.Quit();
         #endif
     }
 }

Use this class from anywhere like this:

 AppHelper.Quit();

UT way of thinking surprises me over and over :)

In my way of thinking the "isX" property should be exclusively a getter.

And methods would be more appropriate for playing and stopping the app - like EditorApplication.stop();

But that's just me ;)

I didn't see a direct call, but this worked in my editor script (dll to be particular):

 EditorApplication.ExecuteMenuItem("Edit/Play");

isPlaying work only in Editor scripts. in runtime use Debug.Break() to pause (not same as Debug.DebugBreak()) http://docs.unity3d.com/Documentation/ScriptReference/Debug.Break.html

Do you know what Debug.DebugBreak() does?

Debug.Break() is pausing the game, not stopping it.

Sadly you can't build a standalone version with "UnityEditor.EditorApplication.isPlaying = false;" in your code, because the class is unknown to the standalone version.

If you don't want to comment out the line everytime you want to produce a standalone build, you can use reflection to dynamically check for the class and change its property:

 using System;
 using System.Reflection;
 
 //only works in a standalone build, ignored in editor and webplayer
 Application.Quit();

 //only works in editor
 //casts "UnityEditor.EditorApplication.isPlaying = false;" dynamically using reflection
 Type t = null;
 foreach (Assembly a in AppDomain.CurrentDomain.GetAssemblies()) {
   t = a.GetType("UnityEditor.EditorApplication");
   if(t != null){
     t.GetProperty("isPlaying").SetValue(null, false, null);
     break;
   }
 }

That's not necessary at all ;)

I'll update my answer.

How about just using conditional compilation? $$anonymous$$uch cleaner, and considerably cheaper than reflection...

 #if UNITY_EDITOR
      Editor.IsPlaying = ....
 #endif

This worked perfectly for me ... many thanks ... if I could package up all the saved clicks and mouse moves and convert them into bitcoins for you, I would! ;)

Application.isPlaying is read only play state. Accessing the menu works, but only on a editor script. Not on a runtime one. EditorApplicatio can't be used there.
