SDL 3

fullscr=0 - the controls didn't work,

Actually they did but the image doesn't update. Edited file graphics/graph2d.c, lines 276...:

Code Select Expand

#elif SDLVER==2
  if(RGLOB_initgr==0){printf("display(): Screen not initialized\r\n"); exit(1);}
  if(SDL_UpdateWindowSurface(RGLOB_window)<0){
    printf("%s",SDL_GetError());
    exit(1);
  }
#else
Error:

Window surface is invalid, please call SDL_GetWindowSurface() to get a new surface

Which version of xMOn@D do you have? I have 0.18.0.

Tyrquake works, but it uses "SDL_CreateRenderer()" instead of "SDL_GetWindowSurface()".

However, unlike my game, tyrquake with SDL 2 had a very low framerate on this laptop with Fedora 14, although it worked well with X11:

0.18.0 here as well.

Anyway, I found a reasonable workaround for me on the XMonad side: remove the borders of Simcar windows upon window creation. If I were to insist on having the borders, it would also have been possible to fix it by growing the window to account for the border, along the lines of what's described in this issue tracker comment.

Those red borders bother me when I try to view a video with MPlayer at full screen, but for the game just leave them:

I will post the fixed graphics/forsdl3/graph2d.c file for you to test it (I can't), but I just found out there might be other problems:

https://wiki.libsdl.org/SDL2/SDL_GetWindowSizeInPixels

"This function is available since SDL 2.26.0."

So for SDL 2 I'll have to use this:

https://wiki.libsdl.org/SDL2/SDL_GetWindowSize

So I will also post file graphics/graph2d.c which I also can't test, so you should, because as mentioned above, my problems with SDL 2 in xMoNad are others - the pointer given by SDL_GetWindowSurface() and the size of the window change after the rendering starts (function display()).

Attached file graphics.tar.gz. First set the settings in xmoNAd back to where they were and try version from simcarstunts-6.2.0:

If the problems still occur, then download file attached here, put files graph2d.c from it in the game source, recompile and see what happens. You can also try with various resolutions in full screen (fullscr=1), with both SDL 3 and SDL 2 (ex.: 960x720).

We think we now have enough contributions coming in monthly to pay for someone to work with us on it.

Problem is, we have no idea who can do this.

Updated game, file simcarstunts-6.2.1.tar.gz:

Xm0NaD aside, you pointed out a problem which could occur with SDL3 even with a graphical window manager that doesn't have bugs:

https://wiki.libsdl.org/SDL3/SDL_GetWindowSize

The window pixel size may differ from its window coordinate size if the window is on a high pixel density display. Use SDL_GetWindowSizeInPixels() or SDL_GetRenderOutputSize() to get the real client area size in pixels.

https://wiki.libsdl.org/SDL3/SDL_CreateWindow

The window size is a request and may be different than expected based on the desktop layout and window manager policies. Your application should be prepared to handle a window of any size.

Solved that, but int SDL 2 there are a few differences:

https://wiki.libsdl.org/SDL2/SDL_CreateWindow

If the window is created with the SDL_WINDOW_ALLOW_HIGHDPI flag, its size in pixels may differ from its size in screen coordinates on platforms with high-DPI support (e.g. iOS and macOS). Use SDL_GetWindowSize() to query the client area's size in screen coordinates,

I didn't create the window with the SDL_WINDOW_ALLOW_HIGHDPI flag, so here I could get the width and height in pixels with SDL_GetWindowSize(). I still have problems with SDL 2 because of some bug(s) in xm0Nad, but I ~solved those too, details in file SDL.txt from the archive mentioned above.
