Physics Body Editor

If you are on the lookout for an engine-independent software utility that you can employ in order to import game assets as well as complete all the tasks related to defining collision outlines, Physics Body Editor could be it.

Also known under the moniker of box2d-editor, the application should be able to handle any physics engine, which means that if you are using Farseer, Chipmunk, or Box2D, for instance, you can rest assured that you are covered.

As for how the Java-based program works, you should know that the outlines it processes are turned into various convex polygons. This allows you to meet any requirements your physics engine of choice might impose.

Retrieving the collision data is subsequently possible provided that you use an in-game loader that looks into the saved images in order to design your bodies.

It is also worth mentioning that Physics Body Editor is capable of tracing your photos automatically and comes with support for multiple outlines for every single body. Aside from that, you may want to know that polygon and circle shapes should not be an issue for the app, and when it comes to the reference point location, changing it should be pretty simple.
