Flash KeyUp/KeyDown messages repeat and thus incorrect
From dis-Emi-A
Flash 9 doesn't have any way to reliably determine if a given key is currently down.
Reason taken from the KeyboardManager.hx in the haXe Library.
Hmm, the messages in Flash are retarded, they send up/down though they are tied to CHARACTER events and not keys themselves, thus when a user pressed any button down (just down) immediately a down then up is sent, then the repeated DOWN message is sent... Quite braindead for use in games.
The sequence seems to be:
- KEYDOWN
- KEYUP (and finish if no longer pressed)
- KEYDOWN (if still being pressed)
- KEYDOWN x N
- KEYUP (when released)
It is the first KEYUP that could be a problem.. On my system there is a good 100ms between the first KEYUP and the next KEYDOWN, that would certainly cause control problems in games.
Hmm, on firefox testing it is even worse, there is a continuous alternation between KeyUp and KeyDown messages.
