AI coding question !!!!

**steven2212** · 22nd Jun 12 9:20 AM

hi everyone ! i'm trying to edit something for the ai.i want to make the ai sapm more heavy unit like m26 pershing or tiger.but i dont know the number demand_incrase like below.i need to put higher number or lower number to make them build more this unit ?
here is the code in the ai_purchasing rule :

if (unitPBG == SBP.ALLIES.M26_PERSHING) then
local count = UtilPBG_CountAlive( SBP.ALLIES.M26_PERSHING )
if (armor_enemy == true or veh_enemy == true) then
if (count < 1) then
demand_increase = 120
elseif (count < 2) then
demand_increase = 80
else
demand_increase = 40
end
elseif (count < 1) then
demand_increase = 70
elseif (count < 2) then
demand_increase = 40
else
demand_increase = 15
end
return demand_increase
end

sorry my bad english

i have one way, but it is just a copy paste thing.
Data\ai\personality\buildorder_lib.ai

then paste this: {"produce", PITEM_Spawn, SBP.ALLIES.M26_PERSHING, maxlimit = 1 },
in every build list
and under each other like:

Code:

allied_buildorder = {
	
	-- this build-order isn't optimal for Allies, but will add some flavor and randomness, even for Hard/Expert.
	{
		name = "Early Support Weapons Then Sniper",	
		fuel_mult = 1.5,
		vp_mult = 0.5,
		list = {
			{"produce", PITEM_Spawn, SBP.ALLIES.ENGINEER, maxlimit = 2 },
			{"building", EBP.ALLIES.ARMORY, maxlimit = 1, bs_style = BS_OuterBase },
			{"produce", PITEM_Spawn, SBP.ALLIES.SNIPER, maxlimit = 3 },
			{"produce", PITEM_Spawn, SBP.ALLIES.HEAVYMG, maxlimit = 3 },
                        {"produce", PITEM_Spawn, SBP.ALLIES.M26_PERSHING, maxlimit = 1 },
                        {"produce", PITEM_Spawn, SBP.ALLIES.M26_PERSHING, maxlimit = 1 },
                        {"produce", PITEM_Spawn, SBP.ALLIES.M26_PERSHING, maxlimit = 1 },
                        }
},

thanks for helping me !

but i did what you said but it's still the same,only build 2 pershing and wait until it die.it build sherman alot.
here it's the code :

Code:

-- Armor
	{	name = "Armor_only",
		filters = { {OnlyOnThisDoctrine, 2 } },
		list = {
			{"produce", PITEM_Spawn, SBP.ALLIES.ENGINEER, maxlimit = 2 },
			{"building", EBP.ALLIES.BARRACKS, maxlimit = 1, bs_style = BS_OuterBase },
			{"building", EBP.ALLIES.TRIAGE, maxlimit = 2, bs_style = BS_NearBase },
			{"produce", PITEM_Spawn, SBP.ALLIES.RIFLEMEN, maxlimit = 3 },
			{"produce", PITEM_Spawn, SBP.ALLIES.HEAVYMG, maxlimit = 2 },
			{"produce", PITEM_Spawn, SBP.ALLIES.MORTAR, maxlimit = 2 },
			{"produce", PITEM_Spawn, SBP.ALLIES.RIFLEMEN, maxlimit = 3 },
			{"building", EBP.ALLIES.ARMORY, maxlimit = 1, bs_style = BS_NearBase },
			{"produce", PITEM_Spawn, SBP.ALLIES.JEEP_RECOILLESS, maxlimit = 2 },
			{"produce", PITEM_Spawn, SBP.ALLIES.SNIPER, maxlimit = 3 },
			{"produce", PITEM_Spawn, SBP.ALLIES.RANGER_TEAM, maxlimit = 2 },
			{"building", EBP.ALLIES.MOTORPOOL, maxlimit = 1, bs_style = BS_OuterBase },
			{"produce", PITEM_Spawn, SBP.ALLIES.M16_HALFTRACK, maxlimit = 3 },
			{"produce", PITEM_Upgrade, UPG.ALLIES.MOTORPOL_UPGRADE, maxlimit = 1 },
			--{"produce", PITEM_Spawn, SBP.ALLIES.GREYSTUART, maxlimit = 3 },
			{"produce", PITEM_Spawn, SBP.ALLIES.GREYHOUND, maxlimit = 2 },
			{"produce", PITEM_Spawn, SBP.ALLIES.M21_MORTAR_HALFTRACK, maxlimit = 2 },
			{"produce", PITEM_Spawn, SBP.ALLIES.M16_HALFTRACK, maxlimit = 3 },
			{"produce", PITEM_Spawn, SBP.ALLIES.RANGER_TEAM_AT, maxlimit = 2 },
			--{"produce", PITEM_Spawn, SBP.ALLIES.GREYSTUART, maxlimit = 3 },
			--{"produce", PITEM_Spawn, SBP.ALLIES.GREYSTUART, maxlimit = 3 },
			{"produce", PITEM_Spawn, SBP.ALLIES.GREYHOUND, maxlimit = 2 },
			{"produce", PITEM_Spawn, SBP.ALLIES.GREYHOUND, maxlimit = 2 },
			{"building", EBP.ALLIES.QUARTER_MASTER, maxlimit = 1, bs_style = BS_NearBase },
			--{"building", EBP.ALLIES.TANK_DEPOT, maxlimit = 1, bs_style = BS_OuterBase },
			{"produce", PITEM_Spawn, SBP.ALLIES.M26_PERSHING, maxlimit = 1 },
			{"produce", PITEM_Spawn, SBP.ALLIES.M26_PERSHING, maxlimit = 1 },
			{"produce", PITEM_Spawn, SBP.ALLIES.M26_PERSHING, maxlimit = 1 },
			{"produce", PITEM_Spawn, SBP.ALLIES.M26_PERSHING, maxlimit = 1 },
			{"produce", PITEM_Spawn, SBP.ALLIES.M26_PERSHING, maxlimit = 1 },
		}

is that a custom one?

make sure there is no requirement that says only 2 unit of that type on the battlefield.
but try reduce this:

Code:

-- Armor
	{	name = "Armor_only",
		filters = { {OnlyOnThisDoctrine, 2 } },
		list = {
			{"produce", PITEM_Spawn, SBP.ALLIES.ENGINEER, maxlimit = 2 },
			{"building", EBP.ALLIES.BARRACKS, maxlimit = 1, bs_style = BS_OuterBase },
			{"building", EBP.ALLIES.TRIAGE, maxlimit = 2, bs_style = BS_NearBase },
			{"produce", PITEM_Spawn, SBP.ALLIES.RIFLEMEN, maxlimit = 3 },
			{"produce", PITEM_Spawn, SBP.ALLIES.HEAVYMG, maxlimit = 2 },
			{"produce", PITEM_Spawn, SBP.ALLIES.MORTAR, maxlimit = 2 },
			{"produce", PITEM_Spawn, SBP.ALLIES.RIFLEMEN, maxlimit = 3 },
			{"building", EBP.ALLIES.ARMORY, maxlimit = 1, bs_style = BS_NearBase },
			{"produce", PITEM_Spawn, SBP.ALLIES.JEEP_RECOILLESS, maxlimit = 2 },
			{"produce", PITEM_Spawn, SBP.ALLIES.SNIPER, maxlimit = 3 },
			{"produce", PITEM_Spawn, SBP.ALLIES.RANGER_TEAM, maxlimit = 2 },
			{"building", EBP.ALLIES.MOTORPOOL, maxlimit = 1, bs_style = BS_OuterBase },
			{"produce", PITEM_Spawn, SBP.ALLIES.M16_HALFTRACK, maxlimit = 3 },
			{"produce", PITEM_Upgrade, UPG.ALLIES.MOTORPOL_UPGRADE, maxlimit = 1 },
			--{"produce", PITEM_Spawn, SBP.ALLIES.GREYSTUART, maxlimit = 3 },
			{"produce", PITEM_Spawn, SBP.ALLIES.GREYHOUND, maxlimit = 2 },
			{"produce", PITEM_Spawn, SBP.ALLIES.M21_MORTAR_HALFTRACK, maxlimit = 2 },
			{"produce", PITEM_Spawn, SBP.ALLIES.M16_HALFTRACK, maxlimit = 3 },
			{"produce", PITEM_Spawn, SBP.ALLIES.RANGER_TEAM_AT, maxlimit = 2 },
			--{"produce", PITEM_Spawn, SBP.ALLIES.GREYSTUART, maxlimit = 3 },
			--{"produce", PITEM_Spawn, SBP.ALLIES.GREYSTUART, maxlimit = 3 },
			{"produce", PITEM_Spawn, SBP.ALLIES.GREYHOUND, maxlimit = 2 },
			{"produce", PITEM_Spawn, SBP.ALLIES.GREYHOUND, maxlimit = 2 },
			{"building", EBP.ALLIES.QUARTER_MASTER, maxlimit = 1, bs_style = BS_NearBase },
			--{"building", EBP.ALLIES.TANK_DEPOT, maxlimit = 1, bs_style = BS_OuterBase },
			{"produce", PITEM_Spawn, SBP.ALLIES.M26_PERSHING, maxlimit = 1 },
			{"produce", PITEM_Spawn, SBP.ALLIES.M26_PERSHING, maxlimit = 2 }, -- im reducing these number
			{"produce", PITEM_Spawn, SBP.ALLIES.M26_PERSHING, maxlimit = 3 }, -- this will maybe help
			{"produce", PITEM_Spawn, SBP.ALLIES.M26_PERSHING, maxlimit = 4 },
			{"produce", PITEM_Spawn, SBP.ALLIES.M26_PERSHING, maxlimit = 5 },
		}

Code:

{"produce", PITEM_Spawn, SBP.ALLIES.M26_PERSHING, maxlimit = 2 }, -- im reducing these number

Code:

maxlimit = 2 }, -- im reducing these number

instead of:

Code:

maxlimit = 1 }, -- it is this number you should try reduce and see what happens

EDIT:

we are actually setting the maxlimit with that.

**steven2212** · 25th Jun 12 10:18 AM

oh,it't still the same,it only build 2 or 3 pershing.not spam like other vehicles.maybe i edit some value in purchasing_rule in my frist post,but i dont know lower demand value or higher value make the ai build more pershing.i also remove the limit of pershing cap.and this is actually ai code form blitzkrig mod.im trying to make the ai more challenge since i only play w computer.

**CoDiEx** · 25th Jun 12 10:46 AM

try set the AI priority up, in the Attrib files

**jojorabbit** · 26th Jun 12 8:17 AM

Code:
{"produce", PITEM_Spawn, SBP.ALLIES.M26_PERSHING, maxlimit = 2 }, -- im reducing these number
Code:
maxlimit = 2 }, -- im reducing these number
instead of:

Code:
maxlimit = 1 }, -- it is this number you should try reduce and see what happens

These are parts of Build orders, build orders are active max for starting 3-6 mins of game later they don't make anything.
I don't have code in front of me currently so i will just write what i remember.
In rules_unit_purchase.ai there are some units lines with AI limits on some units declared as tables like

Code:

axis_purchase_limits = { SBP.AXIS.SOMTHING = 3 }

You can do it that way or you can make new if loop in function for purchasing CT units, something like:

Code:

if(unit_pbg == SBP.ALLIES.PERCHING) then
   if (CountAliveOrProduced(SBP.ALLIES.PERCHING) == 1) then
      return DemandNeverBuild
   else
      return 40
   end
end

Hope it helps.

**steven2212** · 26th Jun 12 10:58 AM

the code is acttually like my first post what should i put to make the ai produce more perching ?
@codiex : where is ai priority ? i cant find it

**CoDiEx** · 27th Jun 12 4:09 AM

in the sbps files: "squad_ai"

**steven2212** · 27th Jun 12 7:04 AM
