So, would you mind giving me any advices?

I have been thinking about the Neoaxis Engine, the Torque 3D Engine, and UDK. Not sure which to pich. Both the Torque 3D and UDK has the ability to those random terrains, I don't know how it is in Neoaxis. Torque 3D could be scripted with C++(programmed), and it has nice physics....

Hey, thanks for the answer. I forgot to state, that I'm okay with the basics of C++. I have done my GSCE exam with it. This is why I said, i would like to be able to script the engine with C++.

Hey, i have done the separating them, although i get an error from the linker: Microsoft DirectX SDK (August 2009)\Include\d3d9types.h Line 51 multiple definition of `dxClass::dxClass()'

What seems to be strange, that this error did not show up, when it was in one file only. It could be beacuse of the static in dxcpp.cpp? what should i do with it?
