I've been looking at the script files for modding units, below is shows the armored train unit as a standard example and I have some questions;
1) I see in the first part they have hp=100 but all unit strengths are "10" and mp=24 when manpower is 2 to produce the unit, so whats up with those numbers?
2) most of the stats are straight forward but some seem duplicated' in the first section you have attack =6 then farther down groundattack = 5, Defense does the something, plus shock and assault are also duplicated, what's the duplication about or for?
3) what does 'weapon = "light"' actually mean, is this were you match up class to determine whether to use highdefence versus base defence?


name = "armouredtrain",
type = "land",
chassis = "rail",
class = "ground",
icon = "armouredtrain",
levels =
{
{
hp = 100,
mp = 24,
ap = 1,
LOS = 1,
range = 1,
shock = 1,
attack = 6,
defense = 6,
airattack = 2,
airdefense = 2,
bombard = 4,
assault = 0,
ammunition = 0,
},
},
retreat = 1,
costPP = 25,
costMP = 2,
turns = 3,
upkeepPP = 1,
upkeepMP = 0,
weapon = "light",
factions = { 0, 1, 2, 3, 4},
strengthValue = 5,


stats =
{
groundattack = 5,
airattack = 2,
armourattack = 2,
basedefense = 11,
highdefense = 6,
assault = 2,
shock = 1,

Ok... there is quite a lot of redundant data in there I'm afraid. The research and stats systems went through various iterations in the development cycle, and some of the elements of the stats file are relics from obsolete systems. Lukas knows this stuff inside out, but basically I think you should ignore everything in the ‘levels’ sub-sections. Everything outside of those sections is a valid stat iirc.
