A suggestion I want to give u that why don't you make a tutorial forum?. or provide some example tutorials in the JPCT packages not the made ones but provide some pages with example codes and descriptions like how to add maps, etc... Like the irrlicht engine's owners did that would be best and very help ful and also a tutorial forum would be much helpful for users because the members will give useful tutorials through which others can get benefit. Sorry for my english if its bad cuz english is not my language. Hope you understand what I wrote.
