I am making a top down game. Where the player moves in 8 directions by angle going 1 pixel every tick or whatever counter its going off of. Now this wouldn't be a problem it seemed like until I tried it on another screen. I work mainly off a 4k monitor and I didn't notice any issue since it was the same screen. I happened to work today off a different monitor which was also 16:9 but it was 1080p. Even though the game looked the exact same in full screen mode, the player was noticeably moving slower in my 4k monitor compared to the 1080 one. I am wondering if there is some way to scale it correctly to not do this? Any help is greatly appreciated.
