Custom Editors and Singletons

Ok So I'm in the process of doing some Major tool development which consists of Unity Custom Editors and lots of Singleton Classes that are created and are vital to my tools. Problem I am finding is that they get destroyed when ever you press the Play Button in the Editor. Is there any way to ensure that things stay created when you attempt to play your game in the editor?

Here's an example of how I create my Singletons:

private static NetworkManager instance = null;
public static NetworkManager Instance
{
get {
if (instance == null)
instance = new NetworkManager();
return instance;
}
}

 

Anyone have a solution for this?

 

You need to add your singletons to a gameobject in the hierarchy (you can create the gameobject as well through script). If you want, you can also hide them, look at http://docs.unity3d.com/ScriptReference/HideFlags.html
