Hi @RichardC
Is it just the ease for stopping the sub you're after?
// this ease just creates a forward<->back-motion
var stopEase = 'M0,0 C0.124,0 0.394,0.151 0.484,0.162 0.656,0.182 0.838,0 1,0';
function _Stop(speed) {
TweenLite.to(div, 0.2, {
ease: CustomEase.create("custom", stopEase),
x: '-=' + 300*speed
});
}
_Stop(0.5);
