AndEngine. Living on the Edge.Just updated to the trunk build of AndEngine which broke almost every line of code I had. There were a bunch of renamings that occurred to replace the concept of scene layers with a more generic child entity structure. The shape modifiers also got moved to another package to differentiate from particle modifiers.
All in all, the transition was smooth and I will now be able to contribute to code back into the main source tree without as many conflicts.
