capital ship limit: RESEARCHSUBJECT_MAXCAPITALSHIPS[race][stage].entity -> perLevelValue (you can set the capitalships' slots per researches)

build speed global: Gameplay.constants -> buildSpeedData (you can modify the multipliers, the 0 is for no change, the negative for slower, the positive is for faster)

build speed per entities: CAPITALSHIP_[..], Frigate[...] & PLANETMODULE_[...] -> BuildTime & baseBuildTime (when the buildSpeedData's multiplier is 0.0, then the BuildTime's value means seconds)

Alright. what about ship cap?

Would I be able to edit cap ship cap and ship cap so that after the first reasearch the limit would go up?

No make a new folder..name it Test mod!

and then copy-paste the files in the reference data section of the Forge tools (but not the entrenchment part if you dont have it)

then apply your chane in your test mod!

and voila!

Set it in your mod folder (look up the path under options --- mods --- show mod path) load game! load mod! Test it

run your game in developer mode (you can find the developer.exes in the forgetools/developer exe, copy that exe into your game's directory, next to the ordinary exe), and there will be a pop-up window when you press the apply changes button, it will tell you what's the problem
