I'd like to implement a kind of animation style where movement is not so nice and smooth, so each 'step' or change of object position is in sync with a change of animation frame (think old school arcade games like Space Invaders ). I've done it simply with a 'move position, change frame, repeat' method but then I lose the nice features of the Bullet behaviour and I have to do everything myself like keeping track of movement, direction, etc. Maybe something with Custom Movement? Does anyone have such a technique? Thanks.
