Physics How-To?

Since i've run into so many issues with jODE, and jBullet under the jMEPhysics 2 repo can I ask would it be wise to attempt to use ray tracing to create a physics entity…Are thier other things I can use with it maybe something in the intersection sub-folder?? I've been looking around the repo all day anyhelp would be apreciated!!!

a triangle collision detection unit can be used to provide physics support.

if u r using jME builtin terrain, for height check, u can just use getHeight method which is just a array lookup.
