Hi,
I’ve been lurking here for a couple of months and spending my time getting familiar with jME. I’m very impressed with what it can do and how easy it seems to get things going.
My project is more like a visualisation tool then a game but it will use most of the same mechanics. I’m sure I will end up pestering you good people for help and advice 
My first question is where’s the best place ask for advice on the approach to different features? Right now I’m working on the terrain side of the project and I’m not sure how to create an endless floor, i.e. a floor that never ends no matter how far or in what direction the user travels.
Thanks in advance for any help.
Hi and welcome. Take a look at the TestTerrainGrid and other TerrainGrid test classes.
propably you will not need it, but if there will be situation for infinite cave, there is a topic:
