The update of Cocos2d-x should not be a problem for LevelHelper. If there is a problem in the code, I can make a change very fast as the code is generated from an online source. For people who don’t have constant internet access, there is also an option to generate the code locally. But if I make changes to the code, those changes will be available to the offline code only with the next update.
In order to release LevelHelper 1.1 fast, “Cocos2d-X with Box2d support” code has only online source. Version 1.2 will bring support for offline code as well and will bring online only for Cocos2d-X with Chipmunk support.
You only have to generate the code only when you create a new tag in LevelHelper. (tags are Enums values placed in the code so you can get pointers to the objects in your level with a specific tag)
