The scripting language the game uses is called Lua. You can learn it here https://www.lua.org/pil/contents.html
Going through that will answer 90% of your questions.

Thanks, this is what I am looking for but to understand it is another question LOL.

One more question - are the blue and white color texts a function ?
Thanks again.

if unit:IsInCategory('MOBILE') then 

(1) How do you use IsInCategory to select only units that moves around and is an attacking type of units.
I tried the above but it also consider Factory and Engineer as Mobile ?

(2) Any blueprint for Tech 3 Transport unit ?

Thanks.

hello SupCom_16-12-20 ,

i guess you already figured out how to use table in tables ?
If not, let me know.

You will maybe find custom LUA commands inside the game.

Here is a list of all commands you can use in SIM-STATE of the game:
https://github.com/FAForever/fa/blob/deploy/fafdevelop/engine/Sim.lua

And here a List of all commands you can use in the UI-STATE of the game:
https://github.com/FAForever/fa/blob/deploy/fafdevelop/engine/User.lua

You can't use SIM-STATE commands in UI-STATE of the game and vise versa.
SIM-STATE commands are for the gamesimulation like moving units etc.
UI-STATE commands are for the user Interface

Here's a list of categories https://wiki.faforever.com/index.php?title=Mission_Scripting#Categories

Thanks. I will use this if I am doing a mission scripting. Now I am trying to work on skirmish game play.

Actually I am looking for these 2 things.
(1) category list for unit that is moving around (mobile type) and an attacking unit.

(2) Blueprint for Tech 3 Transport unit.

Thanks.

@Uveso

To your question - Table in tables. After spending some time reading "Cobrand" code ... I think I roughly know how tables work. I know saying it, is easier than doing it ie. to actually write codes out that actually works without a bug.
I think I will know that when I reach that point.

But right now actually I am stuck in this code here.

local NameTable = import("/mods/Veterename/tables.lua").GetTable()
local allUnits = {} ;
local username = nil ;

function UpdateAllUnits()
    -- Add unit being built by others
    for _, unit in allUnits do
	if not unit:IsDead() and unit:GetFocus() and not unit:GetFocus():IsDead() then
		allUnits[unit:GetFocus():GetEntityId()] = unit:GetFocus()
		end
	end
	
	-- Remove dead
	for entityid, unit in allUnits do
		if unit:IsDead() then
			allUnits[entityid] = nil
		end
	end
end
  
function RenameVet()
        for index, unit in allUnits do
            local Ukills = unit:GetStat('KILLS', 0).Value
            if Ukills >= unit:GetBlueprint().Veteran.Level1 and Ukills != 0 and unit:GetCustomName(unit) == nil then
                local unitname = unit:GetBlueprint().General.UnitName
                local newName ;
                -- commander upgraded name
                if unit:IsInCategory('COMMAND') == true then
                    if Ukills >= unit:GetBlueprint().Veteran.Level5 then
                        newName = "[~[Top Rank: Chief Commander]~]"
                    elseif Ukills >= unit:GetBlueprint().Veteran.Level4 then
                        newName = "[=[2nd Rank: General]=]"
                    elseif Ukills >= unit:GetBlueprint().Veteran.Level3 then

end

The complete code above. Last night I ran the code using this and game still runs okay but I still cannot find out if this thing works or not as I cannot get a unit to stay on battle field long enough to see it's effect.

The last 2 blocks of code, I know for sure it won't work because I have no info as how to trap a unit that is a mobile type ie. moving type of unit and also an attacking type. And also how to trap a Transport Tech 3 unit.

                -- others mobile units that moves around such as land, air and naval units upgraded name
                if unit:IsInCategory('DIRECTFIRE') and ( unit:IsInCategory('NAVAL') or unit:IsInCategory('LAND') or unit:IsInCategory('AIR') ) then
                    if Ukills >= unit:GetBlueprint().Veteran.Level5 then

I don't know how to check if a unit is a mobile type and an attacking type of unit.

                -- ONLY Tech 3 Transport Air units upgraded name
                if unit:IsInCategory('TRANSPORT') and unit:IsInCategory('TECH3') then
                    if Ukills >= unit:GetBlueprint().Veteran.Level5 then

And also don't know how to check if a unit is a Tech 3 Transport unit.

Thanks.

Use LOG commands to print debug text to the game.log.
Like:

if unit:IsInCategory('TRANSPORT') and unit:IsInCategory('TECH3') then
	LOG('Found Unit with category TRANSPORT*TECH3')
        if Ukills >= unit:GetBlueprint().Veteran.Level5 then

To Check For mobil units, you can use
unit:IsInCategory('MOBILE')

units have layer category, so you can ask for land air or naval units:
unit:IsInCategory('LAND')
unit:IsInCategory('AIR')
unit:IsInCategory('NAVAL')

random Examples:

MOBILE * LAND * INDIRECTFIRE * DIRECTFIRE for land units that can attack other land units
MOBILE * LAND * ANTIAIR for mobile Anti Air
MOBILE * AIR * HIGHALTAIR for ASF
MOBILE * AIR * TRANSPORTFOCUS for Air Transporter
(if unit:IsInCategory('MOBILE') and unit:IsInCategory('AIR') and unit:IsInCategory('TRANSPORTFOCUS') then)

Is there any way we could use LOG to extract the blueprint of a specific unit ?

This might help me complete the coding. I will get back to you. Thanks a lot for these.

LOG( repr(BluePrint) )

repr() will print tables.

Don't use this on units or other user/c-objects.

Just bcause its in a mission scripting guide doesnt mean its not valid for the rest of the game.

unit:GetBlueprint().Veteran.Level1

Am I right to say Veteran.Level1 means, it is 1 star as shown below ?

and

unit:GetBlueprint().Veteran.Level2

means 2 stars ?

unit:GetBlueprint().Veteran.Level2

unit:GetBlueprint() will get the blueprint from a unit.

local TableFromBlueprint = unit:GetBlueprint()
LOG(TableFromBlueprint)  -- this will print the whole blueprint into the game.log

You can do it directly without storing it in TableFromBlueprint :

LOG(unit:GetBlueprint())  -- this will print the whole blueprint into the game.log

unit:GetBlueprint().Veteran

local TableFromBlueprint = unit:GetBlueprint()
LOG(TableFromBlueprint.Veteran)  -- this will only print the Veteran table from the blueprint

same as before:

LOG(unit:GetBlueprint().Veteran)  -- this will only print the Veteran table from the blueprint

output:

    Veteran = {
        Level1 = 6,
        Level2 = 12,
        Level3 = 18,
        Level4 = 24,
        Level5 = 30,
    },

unit:GetBlueprint().Veteran.Level2

local TableFromBlueprint = unit:GetBlueprint()
LOG(TableFromBlueprint.Veteran.Level2)  -- this will print the value stored in Veteran/Level2

same as before:

LOG(unit:GetBlueprint().Veteran.Level2)  -- this will print the value stored in Veteran/Level2

output:

12

if it is, then something is wrong with my modified codes. I don't know where the bug is. The Star increased from 1 to 3 stars but the Ranking don't increase ?

Veterancy isnt based on the number of kills but on a killed mass.
