So I could use same handler functions. My problem with the MouseEvent.CLICK is however that I receive it twice - 1 event comes from the PlayingCard and another one seems to be dispatched automatically. Is there please a way to prevent the latter event from being sent? A far better strategy is to stop using generic events and use custom events to differentiate between the individual situations. So, you would have a CardSelectedEvent.CARD_SELECTED being used in your game logic, not generic events. It will make your life much easier. The click of a chosen card would set the current card in your list. The button click would dispatch the CardSelectedEvent.CARD_SELECTED event. In general try and avoid using generic handlers for controlling game logic.

Re: [Flashcoders] AS3: Dispatching events to further listeners, but not to itself
I haven't studied your code in depth - however, I would say this this
is wrong (whatever you are doing):
private function handleMouseMove(event:MouseEvent):void {
// XXX trying to reuse the MOUSE_MOVE event
// XXX and to dispatch it to PlayingTable - fails :-(
dispatchEvent(event);
}
The Flash event system doesn't like redispatching the same event
object. To redispatch an event like this, try the following:
private function handleMouseMove(event:MouseEvent):void {
// XXX trying to reuse the MOUSE_MOVE event
// XXX and to dispatch it to PlayingTable - fails :-(
dispatchEvent(event.clone());
}
HTH,
Ian

[Flashcoders] AS3: Dispatching events to further listeners, but not to itself
Hello,
I have 2 classes: PlayingCard and PlayingTable.
The PlayingCard listens on MOUSE_UP, DOWN
and MOVE to call startDrag() and stopDrag().
I do not want to introduce custom events,
so I try to subscribe the PlayingTable to
MOUSE_MOVE and MOUSE_UP events
of each PlayingCard, so that the table can:
1) Detect that a PlayingCard is being
dragged to a right spot (depending on
the current phase of the game - for ex.
from the dealer to the player), so that
it can change color (like glow in green)
2) Detect that the mouse has been
released after dragging a PlayingCard
and check if the move been valid.
My problem is that when I try to dispatch
the MOUSE_MOVE events, then the
PlayingCard receives it again and again
and gives me the runtime error:
Error #2094: Event dispatch recursion overflow.
at flash.events::EventDispatcher/dispatchEventFunction()
at flash.events::EventDispatcher/dispatchEvent()
at Card/handleMouseMove()
Has anybody please a solution for
this probably often occuring problem?
Thank you
Alex
PS: Here is my current troublesome code:
public function PlayingCard() {
..
addEventListener(MouseEvent.MOUSE_DOWN, handleMouseDown);
}
private function handleMouseDown(event:MouseEvent):void {
addEventListener(MouseEvent.MOUSE_UP, handleMouseUp);
addEventListener(MouseEvent.MOUSE_MOVE, handleMouseMove);
...
startDrag();
}
private function handleMouseUp(event:MouseEvent):void {
removeEventListener(MouseEvent.MOUSE_UP, handleMouseUp);
removeEventListener(MouseEvent.MOUSE_MOVE, handleMouseMove);
..
stopDrag();
}
private function handleMouseMove(event:MouseEvent):void {
// XXX trying to reuse the MOUSE_MOVE event
// XXX and to dispatch it to PlayingTable - fails :-(
dispatchEvent(event);
}

Re: [Flashcoders] AS3: Dispatching events to further listeners, but not to itself
you might find that using MOUSE_MOVE is a little heavy on the processor as
it can fire multiple times, even within the same frame
it's probably better to use Event.ENTER_FRAME and check for the mouseX and
mouseY and while you're at it, you might as well use the same listener to
move the card rather than startDrag()/stopDrag()
don't know if it would help, though
