objective c - sprite kit physicsBody around circles -


so guy , girls got sprite , wounding how create circle physics body around it. maybe using alpha.

what have ball.physicsbody = [skphysicsbody bodywithrectangleofsize:ball.size];

bodywithrectangleofsize puts square on sprite right?

to create circular physics body can either use:

mynode.physicsbody = [skphysicsbody bodywithcircleofradius:10.0];

or 

mynode.physicsbody = [skphysicsbody bodywithcircleofradius:10 center:cgpointmake(0, 0)];

you specify center if looking physics body have offset node's center.
