So I've found the Sample Pack in the misc downloads section which contains some stock components. My question is if those were remade or imported from the game somehow. I'm guessing that the second one is the case, which leads me to the question of how those parts were imported. I'd like to import the default parts and rebuild/take them as base for my mod, however there seems to be no way to import parts, yet those parts exist. I've also found out about PyRA2, which according to the readme can do exactly that:
The current PyRA2 codebase can import both .gmf (3D models of robot components, battle arenas and miscellaneous game items) and .bot files (robot body model and component placement). It can also export both formats to VRML files for viewing in a VRML browser/plugin.
However as I have never used python before, I'd need a little guide on how to get started.
