This is one option. But even with a kinematic body you could in your own code assign it a velocity and apply gravity, air resistance and ground friction each frame. The math is not that complicated really.
oh man, that’s complicated for me lol, i’m shit on math…
but anyway thank you very much, i’ll try the first way first to see if it works,
hope there won’t be any unexepected behaviours. otherwise i have to try the second way which i’m not good on.
