/ Published in: ActionScript 3

Calling this will conditionally trace the list of object names underneath your mouse point. It will only trace when the list of objects beneath the mouse actually changes.

var previousOUM:String = "";
private function listObjectsUnderMouse():void {
	var point:Point = new Point(mouseX, mouseY);
	var objects:Array = stage.getObjectsUnderPoint(point);
	var currentOUM:String = ""; // Objects Under Mouse
	var results:String = "";
	for (var i:int = 0; i < objects.length; i++) 
	{
		currentOUM += DisplayObject(objects[i].parent).name
		if (i != objects.length-1) currentOUM += ", ";
	}
	if (currentOUM != previousOUM) {
		trace(currentOUM);
		previousOUM = currentOUM;
	}

// Variable(s)
var previousOUM:String = "";
