Seperate units for sides, AI problems... Options

[Creagor]

Okay, so I have have made seperate engineers, MWF's etc for my mod. The problem's are not with adding the infantry to the game, but with coding the AI to use the different SHP's.

IE: I want Nod to build [NENGINEER], and GDI to build [GENGINEER], and they must work exactly like the standard [ENGINEER] did - as an engineer. The same applies for the Mobile war factory ( I dont know if the AI built it origionally, if not is it possible to get it working how it should. If yes, how?).

Yes, there are groups for the engineer, but they are shared by both GDI and NOD. I want seperate groups for each, and I dont know how to seperate that into two. I have tried copying the code and assigning it to just one house, but it gives me IE's, probably because I dont know what Im doing. AI really isnt my strong point, so I dont know how to do much with it.
