shape attribute is available in physics.addbody()
An example i tried is as follows.
man = "man.png"
shape1= man.x,man.y,man.x+201,man.y,man.x+201,man.y+201,man.x,man.y+201}
physics.addBody(man,"dynamic",{density = 2,bounce = 0, shape=shape1})
This man object gets separated from all other objects. It dont collide and stop with static objects. Then what is the exact use of this shape attribute???
