Is it possible to modify a shape within a body after assigning it, for example I have a box shape for my game hero body, and when I press the down arrow I want my hero to crouch witch means that I need the body shape to be resized.
I’ve already searched in google but it appears that the topic of modyfing shapes is not so popular. If it’s impossible maybe you know a better way of doing this.
I don’t think it’s possible without something like replacing the shapes and reattaching them to the body.
My suggestion would be to have two separate bodies, one for the bottom part of the character and one for the top part, connected with a prismatic joint.
