by starting a new project i've managed to make the jump method work (don't ask me exactly how, i don't know) and now the ball jumps. the only problem i still have is related to the direction of the jump. If i'm moving forward along the Z axis, and then i jump, the ball doesn't go straight forward on the Z axis as it was going before, it's like it follows an absolute acceleration instead of the relative one of the ball. it just moves on the absolute axis, and not the relative ones of the ball. is there any way to make it follow the on ground direction?
