If just using event.x it doesn't work on a touch device and you'll get NaN To get the x and y coordinates you must add event = Events.touchEvent(event) and then call for event.clientX instead of event.x

EventX and Y on touch device

Dragger = new Layer
	x: 0
	y: 100
	width: 100
	height: 100

Dragger.draggable.enabled = true

Dragger.on Events.DragMove, (event)->
	event = Events.touchEvent(event)
	print event.clientX, event.clientY
