You may want to wait a short while - I can't say it explicitly, but there's an intriguing new SKPhysicsBody
method if you look at pre-release docs at developer.apple.com and search for "iOS 7.1 API Diffs".
There is another way - you can simply create new SKNodes
, add your new nodes as the children of your target composite node, and attach convex SKPhysicsBodies
to these child nodes.
EDIT: this will only work for non-dynamic constituent bodies, if you just want to detect contact/collision on a concave composite one that's static.
