[Super-tux-devel] OpenGL fix

[Ricardo C. <ri...@ae...>]

Hey there,

 I ask for those that have OpenGL problems (looking at Keir Lawson) to try to 
do this: replace all 'screen->w' and 'screen->h' by 'SCREEN_W' and 
'SCREEN_H', respectively (and without the ' ).

 I'm not sure if there is a command line to do this, but you can detect the 
files that use those, by running:
grep 'screen->w' *
 And then, just make use of a text editor to replace them. Maybe Kate allows 
you to do replacements in multiple files...

 Just one thing, you could also try to print the screen->w and screen->h 
values in the st_video_setup_gl() on setup.cpp .

 For those that are wondering "Why the hell does that replacement will fix the 
OpenGL problem?". Here goes the answer:
 When asking for SDL to setup the video mode, the SDL returns a SDL_Surface 
structure that contains a few info about the screen and even allows pixel 
manipulation (in SDL mode).
 But in case, you ask SDL for an OpenGL video mode, there are a lot of 
variables that are not reliable and that can include the display's width and 
height.

Cheers,

 Ricardo Cruz
