How to stop program from looping in Animate CC 2015 - actionscript-3

Question

Animate CC workframeHow do i stop this program from looping? The stop(); function won't work. It is not an animation clip but a drag and drop game. Because I'm still new to AS3, I would appreciate it if someone answered my question with explanations. Thanks!

Answer 1

function checkGame():void {
if ((item1.scaleX = item1.scaleY = 1)&& (item2.scaleX = item2.scaleY = 1)&&(item3.scaleX = item3.scaleY = 1))
{
ilabel.info_txt.text=" Well done!";
item1.removeEventListener(MouseEvent.MOUSE_DOWN, mousePress);
item1.removeEventListener(MouseEvent.MOUSE_UP, mouseRelease);
item2.removeEventListener(MouseEvent.MOUSE_DOWN, mousePress);
item2.removeEventListener(MouseEvent.MOUSE_UP, mouseRelease);
item3.removeEventListener(MouseEvent.MOUSE_DOWN, mousePress);
item3.removeEventListener(MouseEvent.MOUSE_UP, mouseRelease);
}
This will stop the user from being able to select anything.
If you have a movie clip looping on 'item1' for example.
You need to add item1.stop(); also to the checkGame function...
Good luck!
