Action Script 3.0: Stop Drag with hittestobject - actionscript-3

Question

how to stop drag(event) the object with hittestobject.. thanks.
object.addEventListener(TouchEvent.TOUCH_BEGIN, drag);
object.addEventListener(TouchEvent.TOUCH_END,drop);
addEventListener(Event.ENTER_FRAME, loop);
function drag(e:TouchEvent):void {
e.target.startTouchDrag(e.touchPointID);
}
function drop(e:TouchEvent):void {
e.target.stopTouchDrag(e.touchPointID);
}
function loop(e:Event):void {
if (object.hitTestObject(collision)) {
//code to stop drag event?
}
}
or is there other way to stop drag event aside from function drop?
sorry for my bad english.

In the function drop() e.target is the object that currenty processes the event. In the function loop() you also have some objects. It is not clear which of them is dragging but you should call either object.stopTouchDrag() or collision.stopTouchDrag().
UPDATE
There is an argument for both startTouchDrag and stopTouchDrag functions - touchPointID, it is used to determine what touch point (of many) is processed. When stopping the drag, you need to use the same touchPointID which was used for starting it. When calling the stopTouchDrag from a non-event context, you can't know what touch point it should use. So you need to remember it somehow. If your target object is a MovieClip you can just add a dynamic property to it and save the touchPointID there:
function drag(e:TouchEvent):void {
(e.target as MovieClip).touchPointID = e.touchPointID;
e.target.startTouchDrag(e.touchPointID);
}
function loop(e:Event):void {
if (object.hitTestObject(collision)) {
object.stopTouchDrag(object.touchPointID);
}
}
