i need to make an animation frame by frame, basically after pressing the mouse the animation starts by changing background image like some kind of stop motion by using this code:   document.addEventListener('click', function() {         if(counter<1){             audioElement.play();             var cancello=document.getElementById("cancello1");             //var cancello2=document.getElementById("cancello2");             TweenMax.to(cancello, 3, {rotationY:125, transformOrigin:"left top",
