Thanks for answering!
I guess I explained it a bit bad then
By "round sprite", I meant a (normal / square) sprite with some round alpha mask. So I thought it might be possible to do some kind of texture scrolling, masking out the parts you don't want on the sprite (if that's possible).
At least that's what I thought UV offsets could be used for (the scrolling part, not the alpha masking).
Anyway, I went with the animated sprite and setting the angle, which worked pretty well
And yes I'm trying to make a top-down football-ish game, mostly for testing and learning AGK2.
Apologies for any typos and strange grammar.
