sdlcl Instruction for ETQW?

Hello,

I am interested in using the library with Enemy Territory: Quake Wars on Ubuntu Mate 17.10. Can I get some compiling and usage instruction, please? Thank you very much!

Kind regards.

Edit: Here is the name list that I adapted from #9:

According to #8, only missing functions are SDL_GL_DisableContext and SDL_GL_EnableContext_Thread. However, finding those only in SM accelerated binary of Quake 4 and renderer threading binary of ETQW makes me suspect that those are the part of proprietary libSDL-1.2.id.so.0. Can they be ported?

I managed to compile libSDL-1.2.so.0 but as SDL_GL_DisableContext and SDL_GL_EnableContext_Thread functions aren't available I am unable to use threaded renderer which results poor framerate. Is it possible to port those functions?

SDL2 makes implementing this easy enough using SDL_GL_MakeCurrent(). It should work now.

Thanks for the update!

Vanilla game works okay with a minor issue but in case of switching to a mod, the game segfaults.

Makefile is edited to make the custom SDL library;

TARGET = libSDL-1.2.id.so.0

The code is compiled in 32 bit mode;

make CC="gcc -m32"

https://github.com/MrAlert/sdlcl/issues/11#issuecomment-371180674

Results and issues:

Backspace button doesn't work with SDLCL whereas it works with stock libSDL-1.2.id.so.0.
Switching to a mod or switching to vanilla game from a mod via connecting a server or Mods menu crashes the game. Explanation; ETQW restarts itself in case of custom content; mods, custom maps, etc. When the game restarts to switch to a mod, it crashes during "SDL_ListModes" phase which lists supported resolutions. Changing r_useSDLModes value into 0 or 1 in ~/.etqwcl/base/etqwconfig.cfg and/or ~/.etqwcl/moddirectory/etqwconfig.cfg doesn't change the result. If the mod is directly launched with +set fs_game moddirectory argument, the mod launches without an issue.

To reproduce the crash issue:

Download ETQW retail iso and install with LIFLG installer.
Start the game with etqw-rthread script, create an offline account which doesn't require license code, quit.
Download and extract Quake Wars: Tactical Assault mod into ~/.etqwcl directory.
Start the game with etqw-rthread script and try to switch to Quake Wars: Tactical Assault mod, see the crash.

Terminal outputs:

Launching the mod directly with +set fs_game moddirectory argument: https://pastebin.com/rXTDsP4t

Is there any development regarding the issue? Is more information required?

Mar 26 '18 12:03 rea987

Sorry for taking a while. I've looked into it with the ETQW demo, and found that when restarting (I did it by restoring default settings in the settings menu) it calls SDL_Quit() and then calls SDL_Init() again in the same process. SDLCL actually doesn't currently support doing this properly, as it doesn't do any of its own initialization on SDL_Init() or deinitalization on SDL_Quit(). I've commited a quick fix (c963491cf8777e2bad1260d25deb147b8026979c) that appears to resolve the issue here, but proper initialization and deinitialization is still something I'll have to do at some point.

The last commit (c963491) seems to fix the "unable to restart" issue. Thank you! However, backspace button still doesn't function with SDLCL. Please let me know if additional data required.

Adding Unicode control codes manually for certain keys (2d3cc735136c258aaa6fc6b915a648cbe1765fcb) seems to fix the backspace issue.

Mar 30 '18 20:03 MrAlert

Yes, (2d3cc73) has resolved the backspace problem. Thank you! It looks like ETQW is now fully supported. As you are looking forward to implement "proper initialization and deinitialization", I leave this open but if you are satisfied with current state, feel free to close. Thanks for caring and making old games benefit from modern features!

As I have just discovered, ETQW shows black screen if following options are changed;

Aspect Ratio and Resolution in Settings >Simple > Video
Texture Quality in Settings > Advanced

Normally, when those settings are changed and applied, the game shows an initial black screen then immediately return to game screen with new settings. However, with SDLCL, the game remains at black screen which requires killing the process. Texture Quality may require hard restart depending on the settings but that's not related with the issue.

Any development on the latest issue? https://github.com/MrAlert/sdlcl/issues/14#issuecomment-388630899

Further information regarding https://github.com/MrAlert/sdlcl/issues/14#issuecomment-388630899;

Switching between fullscreen and windowed mode in the game also results black screen. Using or not using r_useSDLModes doesn't make a difference.

As @MrAlert is back, let me kindly bump following black screen issue;

https://github.com/MrAlert/sdlcl/issues/14#issuecomment-388630899

Nov 30 '18 20:11 rea987

Alright, I think I know what the problem is. In X11_SetVideoMode, SDL 1.2 resizes the existing window if certain flags and the color depth are the same. SDLCL currently destroys the window and creates a new one, which also destroys the OpenGL context. Since the game isn't expecting this, it then tries to use OpenGL objects that no longer exist. It'll take me a while to fix this, but afterwards it should be easy to implement SDL_RESIZABLE as well.

Nov 30 '18 21:11 MrAlert

@MrAlert I do not know if it is related or not, but simply clicking Apply button without changing anything in Settings causes black screen.

Nov 30 '18 21:11 rea987

ETQW probably always calls SDL_SetVideoMode when you click Apply regardless of whether you actually changed any settings or not.

Nov 30 '18 22:11 MrAlert

@MrAlert As it has been more than 6 months since the last update, is there any news regarding the bug;

Greetings @MrAlert,

Is there any development regarding black screen bug on Enemy Territory: Quake Wars?
