you have to download Java3D OpenGL/Direct3D?.
1. install Robocode
2. install RobocodeGLV014
3. copy all files inside robocode3D.zip into the robocode folder (like RobocodeGLV014)
now you should run TerrainConfig?.bat and set max hill to 0 (JSlider) and don't forget to save. for tests without Robocode run Metavetsum.bat if it works try Robocode3D.bat if you start a new Battle then pause it, and wait until all robots are visible
I have tryed it 2 times, I think it should work if you follow the order. -- Bienator
