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);
}
