I have the box checked "use low-resolution coordinates in script" for a very old game project that was imported from ags 2.6 to 3.21.
Does this in any way affect the game? (like the finding of correct walking paths, or precision of walk behinds etc.)
Is it better to rescript the whole thing into normal resolution?
At the moment I continue to script everything with a division of 2 like:
player.walk (145/2, 123/2);
Like this I have to think less and can use screen coordinates...
Using low-resolution coordinates will only have ill-effect if you have any single-pixel, pixel-perfect room area masks, interactions, other such dependency. It shouldn't affect the engine's pathfinding. And you probably shouldn't have single-pixel fights in the first place unless your game is 320x(200/240), in which case you would be using native coordinates.
So, pretty much, don't worry about it. ;)
