not sure where to post this... ill just leave it here and hope someone who knows what they're doing finds it.
built in weapons are not supported by trylobot's ship editor, as such i thought i'd put together a quick tutorial on it so maybe any newcomers arent as hopelessly confused as i was at first.
basically, plop a bit of text in there saying "builtInWeapons": followed by the weapon system id in between a set of "", followed by the type of weapon. when you're finished it should look something like this: "builtInWeapons": { "WS 001": "tpc", "WS 002": "tpc" },
that bit of text will set the weapon systems with the id 1 and 2 to be designated as built in thermal pulse cannons.

if you're lazy (or terrified of screwing something up)
-copy and paste the example bit into the ship file
-change the "WS 001" to be whatever weapon slot number you want it to be, and do this with all the slots you want to designate as built in weapons
-change the part that says "tpc" to whatever weapon type you want to be built into that slot
-the list of vanilla weapons can be found in: "\Starsector\Fractal Softworks\Starsector\starsector-core\data\weapons"
