Description H.H. 2010-02-06 13:41:00 UTC

Version:           0.9.0 (using 4.3.98 (KDE 4.3.98 (KDE 4.4 RC3)) "release 216", KDE:KDE4:Factory:Desktop / openSUSE_11.2)
Compiler:          gcc
OS:                Linux (x86_64) release 2.6.31.5-0.1-desktop

to reproduce:

You are in following situation:

  #
  #
  ####
  
  ####
O #
  #
  #

you (O) want to move up and then turn right. So while I move up I press additionally the right-arrow-key, so the player should try to go right, as soon as possible. This is standard behaviour in most such games.

In granatier the player continues to move up.

sorry for the long delay, I messed up with the email preferences from bugs.kde.org and didn't get an email for this report.

to your question. I already tried what you suggested but it was error prone, because it's not easy to get the state of a key, only the press and release events. therefore, if the game is paused and then the keys are released, I don't have the right states.
I will try to find a solution, but at the moment there are other more important things to do, like an arena editor.

I can actually confirm this one.
As Mathias mentioned, only the latest press and release events seem to be grabbed. So there's no actual simultaneous press: if you hold left and then up, it heads up, and if you hold up and then left, it heads left.

It is true that games with top-down perspective (like Zelda, Bomberman, Pacman) often allow for a sort of diagonal walk-by:
If walking to right and you bump into a wall, simultaneously pressing right and up will move you up along the wall and enter the first crevice/opening you find to the right. This is true even in games that don't allow for diagonal movement.
