I don't know why these methods only exist on the simulator, not in the build. I will reopen once I get it resolved. |

To get methods into the build you have to build templates for specified platforms. There are some issues with the PR, I will fill them UP and merge it. |

I'm doing some projects using Box2D and really need some methods inside Box2D that Solar2D doesn't provide yet.
Some previous requests also existed on the forum:
