I'm a first time TW modder, and using the tutorials I created a Pirate Dragoon unit. I took the values from Darthmod 0,6 and am able to play with the unit using The Great Campaign Expanded-Faction Inclusion Mod.
I made the mod by copying darthmod and renaming it mydarthmod, edited the existing files (adding the lines needed to create new units), and copied over other files from patch.pack.
My question is, how do I create a mod that can extend Darthmod, adding new units, without copying any of his work? I know that if I created my own pack, it would overwrite any files that also existed in Darthmod. Is there anyway make a pack modify parts of existing files without completely overriding them? Like if I just wanted to add a few lines to the end of units_stats_land?
