Well I always thought that reading the actual stuff you were "copying and pasting" was pretty much self explainatory. Most of the code is simple to understand while the few stuff that isn't, say that generally stuff that have the prefix of OCL_ reference to the ObjectCreationList ini file or FX_ references to the FXList file. Then again, I've actually done a bit of normal programming, which is a lot more difficult.
The thing is whenever you make a unit, it's easier to just copy and paste, instead of starting from scratch. You'll need to copy and/or modify the following items:
Object\WhatEverFile -> Your INI file that contains your object
CommandButton -> Your Unit's special buttons (ie - RemoteDemoCharge, Upgrades, and it's build button)
CommandSet -> Your Unit's button list when selected and modify the building's commandset so that your unit will be built.
ObjectCreationList -> Any upgrades/death debris/etc.
FXList -> Any ParticleEffect Sets for your unit
ParticleSystem -> ParticleEffects, if you made any custom ones
Weapon -> If you unit attacks differently from other units.
Upgrade -> If you have any unique upgrades
With all that stuff to modify, it's so much simplier to copy&paste.
If you want me to make a step-by-step tutorial, with explainations on what's going on. Feel free to request. Just don't expect it to be done it 5 minutes.
