Failed Singleton Base Class

Failed Singleton base class:

package com.JM.baseClasses.designPatterns.singleton_baseClass{
 
 //A singleton pattern baseclass.
 //for any object that should never have
 //more than one instance.
 
 public class Singleton_BaseClass {
  
  private static var oneInstanceExists:Boolean = false;

  public function Singleton_BaseClass() 
  {
   if(oneInstanceExists){
    throw new Error("classes that derive from singleton can only be instantiated ONCE.");
   }else{
    oneInstanceExists = true;
   }//[x]
   
  }

 }//class
}//package

The idea was to make multiple singleton classes that could extend from this base class. And make it so you could only have ONE instance of each unique singleton class. This base class did not work, because all classes that extend from "Singleton_BaseClass" share the same static variables. I was hoping each class that extended from the "Singleton_BaseClass" would get a UNIQUE copy of the static variable "oneInstanceExists". This has not been the case. Idea to make this work: Make "oneInstanceExists" a dictionary instead of a boolean. Make classes derived from "Singleton_BaseClass" self-identify their type and load that type into the dictionary. The base-class constructor will check to make sure the type does not already exist in the dictionary. If it does, we throw an error.

Sin Blast Pooler Class

This is a demo of a sin-wave based particle effect I coded. In order to code this effect I made a "sinParticle" class and then a compound particle effect class called "sinBlast". I then made a pooling class that holds "sinBlast" instances so that their instantiation is easy to implement and efficient on memory and processing power. NOTE: You need to wait about 3 seconds before clicking as the screen needs to get ready. I'll work on fixing this glitch later.
