Soda supported window sizes

SuperMatCat24

Is there a list of the sizes that a fullscreen window will resize to? Im making a windowManager to dynamically scale the window and sprites inside it so that the game is the same size for everyone, but i cant find anything about fullscreen sizes in the code. Thanks

EDIT: I got chatgpt to generate the most common aspect ratios. Will these be accurate when put in fullscreen?
// All window sizes with aspect ratios windowSizes = [ [640, 480, "4:3"], [800, 600, "4:3"], [1024, 768, "4:3"], [1280, 720, "16:9"], [1280, 800, "16:10"], [1366, 768, "16:9"], [1440, 900, "16:10"], [1600, 900, "16:9"], [1600, 1200, "4:3"], [1680, 1050, "16:10"], [1920, 1080, "16:9"], [1920, 1200, "16:10"], [2048, 1536, "4:3"], [2560, 1080, "21:9"], [2560, 1440, "16:9"], [2560, 1600, "16:10"], [3000, 2000, "3:2"], [3440, 1440, "21:9"], [3840, 1080, "32:9"], [3840, 1600, "21:9"], [3840, 2160, "16:9"], [4500, 3000, "3:2"], [5120, 1440, "32:9"]

I guess? "Full screen" just means whatever the actual resolution of the display is. You can (and I guess have) look up what the most common display sizes are. But in the end, I think you just need to check the actual window width and height and adjust accordingly. (See tests/window.ms.)

Thanks! Is there a proper way to enter and exit fullscreen? On Windows, after toggling fullscreen, the window sometimes appears with an outdated theme (like Vista), or doesnt have one at all until clicked / the window is updated. Is this a bug, or something specific to Windows?

There's only one way (assigning to window.fullScreen), and it sounds like you found it.

So it also sounds like there may be a bug in the Windows version of SDL. This would be a good one to ask on the SDL forums/discord!

One way i found that fixed it was to swap SDL_WINDOW_FULLSCREEN in line 290 of sdlglue.cpp with SDL_WINDOW_FULLSCREEN_DESKTOP (Which I think just changes it to borderless windowed, but I cant be sure), but I don't know about how this affects non-windows devices.

Huh. Those are indeed different modes. Check out ChatGPT's analysis of the differences.

I guess SDL_WINDOW_FULLSCREEN_DESKTOP is the safer choice, but I could imagine somebody making a retro game might prefer to actually switch the display resolution. I dunno, what do you think about it?

SuperMatCat24

Well, changing the screen resolution also comes with some horrible filtering if it's lower than the display resolution (and makes the mouse way too fast), so I personally wouldn't make a retro game with it. With FULLSCREEN_DESKTOP, ChatGPT says that you need to scale the resolution, and with nearest neighbour that might make pixel-art games look better(?). I'm not sure exactly though, I'm not expert on the subject xD
