Y axis actionscript tweening

programming flash
1

I am wanting to make a set of MCs move when another MC is released; so far i have the following AS, but I am really unsure on how to use AS for tweening;


this.btn1.onRelease = function(){
	btn1.gotoAndPlay("_down");
}

I have tried to find something relevant in here but there seems to be nothing on just tweening in the y axis. Could I possibly get a point in the right direction?

Thanks for your time :slight_smile:
