Refactored the entire level object definition structure, got rid of the union stuff that anon called retarded (it was, I agree now) and am now simply storing an enum (type) and void* for each object in the level definition. Also vehicle definitions are now saved as files on disk, in the future I will probably create a vehicle editor for editing these. This refactor now makes it possible to save a texture file path along each polygon definition so maybe tomorrow I can start working on polygon texture loading and mapping.
