[RESOLVED] Easing with buttons

[pumpkin2006]

Hello!

I've written some basic code to move a ball to the mouses _x and _y position with easing.

onClipEvent (enterFrame) {
	xp = _xmouse/10;
	yp = _ymouse/10;
	_x = _x+xp;
	_y = _y+yp;	
}

Thing is, i'd like to control the ball by pressing on screen keys (up, down, left, right) instead of using the mouse position as this will be appearing on a touch screen without a keyboard or mouse.
How do I go about doing this?
I've attached my .fla so show what I mean.

Thanks!
