FOSS gamedev and creative worlds

Hi! I know the file “screenshot.png” can be used as a preview image for mods. However, I don't know which size I should use. It seems the displayed size in the main menu has varied a lot between Minetest versions.

So is there any size you can recommend? Is there even a guarantee that the screenshot won't be distorted again in future Minetest version because of changes to the display size?

use at least 200 by 150 px

That does not help me much. I want to know a precise size. Or at least I need to know the correct aspect ratio.
If these numbers are even reliable for future versions. ;-(

Finaly i found my old post. I had the same question again. Dont know why it is in WIP Mods.

not shure if its already uptodate.

From the source, it seems the aspect ratio is 3:2. The *actual* (as in, pixel) dimensions of the image vary depending on screen resolution/window size and is scaled accordingly.

EDIT: Maybe 360x240 would be a good choice (480x320 if you want/need more detail).
