I liked the idea of a time-progression on a fuel efficiency, and to the fact to make engineers more valuable I've had a mod that returns old hyperspace travelling fuel cost as well. So I want a mod to return the old crew engineer's mechanics. The problem: It's not enough to simply mod/patch "npcs/crew/crewmemberengineer.npctype" file, because the script of crew benefits itself has been changed ("scripts/companions/crewbenefits.lua"). In older versions of Starbound there was a "PeriodicMultiplier" type of "benefits", now there's "ShipUpgradeBenefit" instead (upd: which seemingly doesn't support a "Period" field). I want to preserve both types of ship benefits if possible. I have all old files on my hand, but I can't combine old and new crewbenefits in an one .lua file because I don't know how to write code. If allowed, I can send them in this thread. Of course, copy-paste of missing code from 1.2 version leads to errors, but not quite as expected: old crew benefits won't work, but it would not affect any other crew; also engineers wouldn't be able to combat on ground anymore, they would instantly die on any planet with this error: [19:17:46.646] [Error] Exception while invoking lua message handler for message 'recruit.status'. (LuaException) Error code 2, [string "/scripts/udrecruitablecompat.lua"]:200: attempt to index a nil value (field 'itemSlots') stack traceback: [C]: in metamethod '__index' [string "/scripts/udrecruitablecompat.lua"]:200: in function <[string "/scripts/udrecruitablecompat.lua"]:157> (...tail calls...) ...I'll continue on experimenting, but if someone knows... what should I do? Is it even possible to roll back to old mechanics at least, and if so, to combine all of them?
