Does anyone have any ideas about how to add a new factory type to make units that I have edited? I am a little bit familiar with the unit_list.json and the build.js files, but I keep running into problems. Do I need to make my own UNITTYPE or category for my factory for build.js? For what I understand, would an example be?: "/pa/units/land/amphibious_tank/amphibious_tank.json": ["amphibious", 6], Instead of: "/pa/units/land/amphibious_tank/amphibious_tank.json": ["vehicle", 6], If so, how would I do this? An example of the factory I have in mind is a amphibious factory that makes amphibious units only.
