I did Some modifications in the flybycamera class a long time ago. Today I updated to the newest jme3 build,
for using the flybycamera modification I svn checked out, but I don’t really intend to do that again…

How to use a custom flybycamera without modifying the engine original flybycamera? So that I can simply disable the old and use mine?
I really don’t like modifying the engine just for one class… Because everytime I make a small change in the fbcamera I need to rebuild.

Sorry for my bad english, its really hard for me to explain in english, so if something is not clear just say it.

Never mind… Solved, it was the appstate i had to detach, simply making another appstate and attaching that Solved it…
