This uses the button's instance name to assign functions. Instead of using a bunch of event listeners, you can use one function to delegate actions according to the button's instance name.

  1. // Assumes that the following buttons with instance names are on the stage
  2. // shape1, shape2, shape3, shape4, shape5
  3. // bg1, bg2, bg3, bg4, bg5
  4. // font1, font2, font3, font4, font5
  5. // color1, color2, color3, color4, color5
  6. //
  7. // This goes thought all the children and cleans out the generic "instance" named children and assigns the rest a click listener
  8. for (var i:int = 0; i < numChildren; i++) {
  9. 	var tempName:String = getChildAt(i).name.replace(/\d/g,'');
  10. 	if (tempName != "instance") {
  11. 		getChildAt(i).addEventListener(MouseEvent.CLICK, myButton);
  12. 	}
  13. }
  14. // Once clicked, this function uses the variables in the name to assign actions
  15. function myButton(evt:MouseEvent):void {
  16.  
  17. 	var goToFrame:int = evt.currentTarget.name.replace(/\D/g,'');
  18. 	var tempName:String = evt.currentTarget.name.replace(/\d/g,'');
