[Announce] Allegro-4.4.2 on extras-devel (needs work)
 
1 Attachment(s)
Latest Allegro 4 (version 4.4.2) is on extras-devel. It is not working very good, so if somebody had any ideas for it...

Wiki: http://wiki.maemo.org/Allegro

Issues:
*In fullscreen Allegro grabs the keyboard
'Grabs' = system wide shortcuts e.g. ctrl+backspace nor screenshots with ctrl+shift+p are not working.
These are working in windowed mode.

*Sounds use too much processing power
Rename/remove file /usr/lib/allegro/4.4.2/alleg-alsadigi.so to disable sounds.

*Fullscreen is not fullscreen. Window manager's top-panel is still visible, but not focusable.

*Can't start from menu, because started application stay bottom than desktop -> nobody has focus.

Package name is liballeg4.4, and relating dev package is liballeg4.4-dev.

I think you missed a bit ;)

Quote:
Allegro 4 and Allegro 5 are cross-platform, libraries mainly aimed at video game and multimedia programming. They handle common, low-level tasks such as creating windows, accepting user input, loading data, drawing images, playing sounds, etc. and generally abstracting away the underlying platform. However, Allegro is not a game engine: you are free to design and structure your program as you like.

If this is working properly, we might get Zelda Classic running under Maemo, because there is a Pandora port. :) (It requires Allegro.)

I have ported the game Head Over Heels and uploaded it to extras.

It also suffers the same problems with performance and fullscreen.

I've seen in changelog that a similar "keyboard focus lost" problem was fixed for OSX in version 4.4.2. See here eighth line.

Maybe the same fix is useful for Maemo, though I haven't checked the code myself.
