Hey i'm trying to figure out something

Say 2 objects are colliding and I'm doing something like


TweenLite.to(tiles[0], 2, {physics2D:{velocity:400, angle:0}, onUpdate:checkCollision});

function checkCollision(){
  var colliding = Draggable.hitTest(this.target, tiles[5]);

What i want instead is to update the original tween's velocity/angle to be smaller and not kill the tween. Is that possible or do i have to make a new tween?

Why don't you want to kill it? Is it causing a jump when you create a new one? Or are you trying to keep the duration the same?


Do you think you can make a simple demo of what you're trying to do? There might be some other approaches if I can see what's going on. You can use the physics plugins on CodePen by using the url from here.
