Just thinking out loud, but I took a look at the code and I am wondering
if this would this not be better implemented as a singleton?

Hi,
I would suggest using a "keyboard manager" class that tracks when
various keys are pressed and sets a flag - this would effectively
allow you to "Poll" such keys when you are checking others.
There is a good example from Richard Lord here:

In an application I am building I need to detect whether the (right)
alt-key

control key isn't being pressed at the same time.
But it looks like the Keyboard events for both MOUSE_DOWN and MOUSE_UP
always return true for ctrlKey (when it is not actual pressed!) while
the
Alt key is pressed.
Simplified test code:
import flash.events.KeyboardEvent;
stage.addEventListener(KeyboardEvent.KEY_DOWN, onKeyDownHandler);
stage.addEventListener(KeyboardEvent.KEY_UP, onKeyUpHandler);
function onKeyDownHandler(e:KeyboardEvent):void
{
trace("onKeyDown: e.ctrlKey=" + e.ctrlKey + ", e.altKey=" +
e.altKey);
}
function onKeyUpHandler(e:KeyboardEvent):void
{
trace("onKeyUp: e.ctrlKey=" + e.ctrlKey + ", e.altKey=" + e.altKey);
}
When I test the code (tested on 2 PC's with Flash 10 or 10.1 Debug
player in
Flash pro CS5 or via same version debug players in MSIE/FF browsers) and
press only the right alt key or a key combi e.g. right-alt-5 the traces
report always true for the ctrlKey, so even when it isn't pressed!?
I checked the Adobe bug base, tried Google, but didn't find anything
related
so far.
What am I missing?
Thanks.
