i made all the joints you need to move movable. this is semi-finished. provide credit to me if you use this. credits to this for the idea: https://scratch.mit.edu/projects/470673427/ you might notice for the animations i cheated a little bit with the limbs. if so then why are you looking at the vectors for any other animation than the spinning animation.
