javascript singleton implementation

Unity Engine

hi! i am trying to implement singleton class but i am totally confused.

i made a class that i want to use in my project it goes something like this (this is the simplified version):

 class EControl{
        
         var state : boolean;
        
         //constructor
         function EControl(){
           state=false;
         }
        
         function getState() : boolean{
           return state;
         }
    
    }

so i later on i realized that i need to have to access object of this class in more then one script and has to be the same object so the value that is set is the same. i was looking what is available in the forums and i found two resources. this one i dont understand http://www.unifycommunity.com/wiki/index.php?title=AManagerClass and this one
is not working (i get “there is no instance”) http://forum.unity3d.com/viewtopic.php?p=388784#388784

so i would appreciate if someone could explain how to make this work and how to use one object of this class in two separate scripts.

thank you!

I answered your question and posted a sample Singleton class in the old thread.

EDIT: Considering your code/sample above, I’m guessing you’ve never created a singleton in any language before. Here’s some info: Singleton pattern - Wikipedia
