ghost-body
p2 add-on for bodies that detect collision but have no collision response.
What this does
A ghost body will not bounce off of or have friction with other bodies. You can still react to a ghost overlapping other bodies via World's beginContact event.
Ghost bodies fire events when other bodies enter/exit them.
