Change Buildcosts ONLY for AI players ...

RxTEAM · **Joined:** 02 Jun, 2010 **Posts:** 188

Hi,

have seen in BO:Unleashed Balance mod that is is possible to change unit datas selective by human player or AI ...
But the code here is set for Human player ....
I need to change the Buildcosts (specialy the energy build costs) from a couple of buildings for AI players ONLY ....
So any help here would be welcome

Hi,

I did this for burnie in the total mayhem mod, it will also work for you..

http://pastebin.com/rSBYWCm2

just put the unit bp ids of the units you want to lower the cost to build in

Code:

local LowerCostUnits = { }

like

EX: local LowerCostUnits = { 'uel0001', 'uel0002' }
in lower case!

you can also change the mult, 0.25 is a 25% decrease in cost for building mobile units.

Do I have to make a Blueprints.lua file in /mods/mymod/hook/lua/ and paste your code in?
If not, how to make it work?

Hi,

it would go in unit.lua in /hook/lua/sim/unit.lua

Hi,

thanks Domino ....
But i look more for an script like this in /hook/units/UAL0309/UAL0309_script.lua :

Code:

local prevClass = UAL0309

UAL0309 = Class(prevClass) {
    OnCreate = function(self)
        prevClass.OnCreate(self)
        if self:GetAIBrain().BrainType == 'Human' then
            self:AddBuildRestriction(categories.AEON * categories.BUILTBYTIER4COMMANDER)
        end
    end,
}
TypeClass = UAL0309

The only diff i need is (except i will change other units - to preciese ,the FABs ..) , i need the changes NOT for Human player - ONLY for AI player and i need to change the energy build costs ...

AddBuildRestriction is an engine function. There may not be an equivalent function for changing build costs.

Hi,

so will this work ? :

Code:

local prevClass = UAL0309

UAL0309 = Class(prevClass) {
    OnCreate = function(self)
        prevClass.OnCreate(self)
        if self:GetAIBrain().BrainType != 'Human' then
            self:bp.Economy.BuildCostEnergy = bp.Economy.BuildCostEnergy * 0.25
        end
    end,
}
TypeClass = UAL0309

have never doing scripts modding ... so i dont know which syntax/commands is available ......

Hi,

No pal, the only way i know of on how to lower the cost of building for
the AI only via script is to use the code snippet i posted..

what it actually does is give the unit an adjacency buff bonus just for that build.
its quick and easy and it works..

Hi,

o.k. ... if this the only way then i musst it go

Have looked over the code and i think this should work to get the AI an 75% energy bonus by build the unit ual0309 (make it musst only pay 25% of the regulare energy) :

Code:

    do
     
    local oldUnit=Unit
    Unit = Class(oldUnit) {
    OnStartBuild = function(self, unitBeingBuilt, order)
            oldUnit.OnStartBuild(self, unitBeingBuilt, order)
                   
            if order == 'MobileBuild' then
                    local LowerCostUnits = {
                    ual0309     
                    }
                   
                    local UBBBPID = unitBeingBuilt:GetBlueprint().BlueprintId
                    local mult = 0.75
                           
                    if table.find(LowerCostUnits, UBBBPID) then
                            local AIBrain = self:GetAIBrain()
                            if AIBrain.BrainType != 'Human' then
                                    self.EconChangedForIA = true
                                    self.EconChangedForIAValues = { Energy = self.EnergyBuildAdjMod }
                                    self.EnergyBuildAdjMod = mult
                                    self:UpdateConsumptionValues()
                            end
                    else
                            if self.EconChangedForIA then
                                    local LastValues = self.EconChangedForIAValues
                                    self.EnergyBuildAdjMod = LastValues.Energy or nil
                                    self:UpdateConsumptionValues()
                                    self.EconChangedForIAValues = nil
                                    self.EconChangedForIA = nil
                            end
                    end
            end
     end,
    }
     
    end

But one thing i get confused : if order == 'MobileBuild' then....
If i understand this right - it only works is this unit build by an mobile builder (enginer as example ..) .. but i need to change the cost of the FABs IF it build by an enginer or IF it upgraded ....

Hi,

IF you can wait til tomorrow, ill fix it to what you want it to do
for factorybuild also and enhancing, ill also factor in the current buff if any
and add that to the mult so you will end up with buffs + mult = cost..

im not doing any scripting tonight am recovering lol.

Hi,

VERY Thanks Domino

To clarify it better ...
I need this :
Human Player
Build FAB -> 100% Energy costs
Upgrade FAB from T1 to T2 or T2 to T3 -> 100% Energy costs
(so no need of change Human player values ..)
AI Player
Build FAB -> 25% Energy costs
Upgrade -> 25% Energy costs
The AI should get FABs and upgrades of FABs to lower energy costs

The Unit IDs i know ....(this i can self set)

Hi,

Code:

do
     
    local oldUnit=Unit
    Unit = Class(oldUnit) {
    OnStartBuild = function(self, unitBeingBuilt, order)
      oldUnit.OnStartBuild(self, unitBeingBuilt, order)
                   
      local LowerCostUnits = { 'ual0309', 'upgradeunitid', 'nextupgradeunitid', 'and so on' }
                   
      local UBBBPID = unitBeingBuilt:GetBlueprint().BlueprintId
      local mult = 0.25 -- 25% decrease in cost
                           
      if table.find(LowerCostUnits, UBBBPID) then
         local AIBrain = self:GetAIBrain()
         if AIBrain.BrainType != 'Human' then
            self.EconChangedForIA = true
            self.EconChangedForIAValues = { Energy = self.EnergyBuildAdjMod, Mass = self.MassBuildAdjMod }
            self.EnergyBuildAdjMod = (self.EnergyBuildAdjMod or 0) + mult
            self.MassBuildAdjMod = (self.self.MassBuildAdjMod or 0) + mult
            self:UpdateConsumptionValues()
         end
      else
         if self.EconChangedForIA then
            local LastValues = self.EconChangedForIAValues
            self.EnergyBuildAdjMod = LastValues.Energy or nil
            self.MassBuildAdjMod = LastValues.Mass or nil
            self:UpdateConsumptionValues()
            self.EconChangedForIAValues = nil
            self.EconChangedForIA = nil
         end
      end
   end,
    }
     
    end

so in this if any unit id is matched for the building of... its costs will get a 25% reduction from its current value, buffs included, so if if the unit already has a 10% buff add 25% to that will give it a 35% reduction.. just for AI units, you can use this to reduce the cost of any unit building or upgrading any other unit just enter the unit ids of the upgrade unit or the unit that is being built.

The code goes in a hooked unit.lua using oldUnit as the unit hook identifier.

Hi,

BIG Thanks Domino

If i remember my long time ago programming skills correct

... then this should work, besides the filling with correct ID numbers for the units .. :

Code:

do
     
    local oldUnit=Unit
    Unit = Class(oldUnit) {
    OnStartBuild = function(self, unitBeingBuilt, order)
      oldUnit.OnStartBuild(self, unitBeingBuilt, order)
                   
      local LowerCostUnits1 = { 'ual0309', 'upgradeunitid', 'nextupgradeunitid', 'and so on' }
      local LowerCostUnits2 = { 'ual0309', 'upgradeunitid', 'nextupgradeunitid', 'and so on' }
      local LowerCostUnits3 = { 'ual0309', 'upgradeunitid', 'nextupgradeunitid', 'and so on' }
                   
      local UBBBPID = unitBeingBuilt:GetBlueprint().BlueprintId
      local mult1 = 0.75 -- 75% decrease in cost
      local mult2 = 0.50 -- 50% decrease in cost
      local mult3 = 0.33 -- 33% decrease in cost
                           
      if table.find(LowerCostUnits1, UBBBPID) then
         local AIBrain = self:GetAIBrain()
         if AIBrain.BrainType != 'Human' then
            self.EconChangedForIA = true
            self.EconChangedForIAValues = { Energy = self.EnergyBuildAdjMod, Mass = self.MassBuildAdjMod }
            self.EnergyBuildAdjMod = (self.EnergyBuildAdjMod or 0) + mult1
            self.MassBuildAdjMod = (self.self.MassBuildAdjMod or 0)
            self:UpdateConsumptionValues()
         end
      elseif table.find(LowerCostUnits2, UBBBPID) then
         local AIBrain = self:GetAIBrain()
         if AIBrain.BrainType != 'Human' then
            self.EconChangedForIA = true
            self.EconChangedForIAValues = { Energy = self.EnergyBuildAdjMod, Mass = self.MassBuildAdjMod }
            self.EnergyBuildAdjMod = (self.EnergyBuildAdjMod or 0) + mult2
            self.MassBuildAdjMod = (self.self.MassBuildAdjMod or 0)
            self:UpdateConsumptionValues()
         end
      elseif table.find(LowerCostUnits3, UBBBPID) then
         local AIBrain = self:GetAIBrain()
         if AIBrain.BrainType != 'Human' then
            self.EconChangedForIA = true
            self.EconChangedForIAValues = { Energy = self.EnergyBuildAdjMod, Mass = self.MassBuildAdjMod }
            self.EnergyBuildAdjMod = (self.EnergyBuildAdjMod or 0) + mult3
            self.MassBuildAdjMod = (self.self.MassBuildAdjMod or 0)
            self:UpdateConsumptionValues()
         end
      else
         if self.EconChangedForIA then
            local LastValues = self.EconChangedForIAValues
            self.EnergyBuildAdjMod = LastValues.Energy or nil
            self.MassBuildAdjMod = LastValues.Mass or nil
            self:UpdateConsumptionValues()
            self.EconChangedForIAValues = nil
            self.EconChangedForIA = nil
         end
      end
   end,
    }
end

The only thing i am not sure is the "mass" part of the script ...
I dont need to change anything on the mass (as my mod push mainly the energy costs, and the AI cant handle this good ....) and so i remove the "mult" from the mass lines ... or can i remove the lines with "mass" then completly ?
(i am not sure musst the lines with "mass" still stay here ....)

sure yeah that will work,

if you dont need the mass stuff just remove it

Hi,

soooo ..... many thanks again Domino for the code

Have now testet (change the ..Braintype != Human to == Human

) and found a couple of bugs ... but i get sortet all ...
First the Buffs counting was wrong ->
0.25 get not an 25% buffer - it multiplied the base value WITH 0.25 and so you get an 75% buff ....
And so its your code to add the buffs wrong too - as your asumed buff 0f 0.10 (10% i think you will get) is 0.90 ... and add to 0.25 the 0.90 you get over 1.x ....

Right it is -> 0.25 * 0.90.
So here the corrected working code :

Code:

do
     
    local oldUnit=Unit
    Unit = Class(oldUnit) {
    OnStartBuild = function(self, unitBeingBuilt, order)
      oldUnit.OnStartBuild(self, unitBeingBuilt, order)
                   
      local LowerCostUnits1 = { 'uab0202', 'uab0302', 'ueb0202', 'ueb0302', 'urb0202', 'urb0302', 'xsb0202', 'xsb0302' }
      local LowerCostUnits2 = { 'uab0201', 'uab0301', 'ueb0201', 'ueb0301', 'urb0201', 'urb0301', 'xsb0201', 'xsb0301' }
      local LowerCostUnits3 = { 'uab0203', 'uab0303', 'ueb0203', 'ueb0303', 'urb0203', 'urb0303', 'xsb0203', 'xsb0303' }
                   
      local UBBBPID = unitBeingBuilt:GetBlueprint().BlueprintId
      local mult1 = 0.25 -- 75% decrease in cost
      local mult2 = 0.45 -- 65% decrease in cost
      local mult3 = 0.70 -- 30% decrease in cost
                           
      if table.find(LowerCostUnits1, UBBBPID) then
         local AIBrain = self:GetAIBrain()
         if AIBrain.BrainType != 'Human' then
            self.EconChangedForIA = true
            self.EconChangedForIAValues = { Energy = self.EnergyBuildAdjMod }
            if self.EnergyBuildAdjMod > 0 then
               mult1 = mult1 * self.EnergyBuildAdjMod
            end
            self.EnergyBuildAdjMod = mult1
            self:UpdateConsumptionValues()
         end
      elseif table.find(LowerCostUnits2, UBBBPID) then
         local AIBrain = self:GetAIBrain()
         if AIBrain.BrainType != 'Human' then
            self.EconChangedForIA = true
            self.EconChangedForIAValues = { Energy = self.EnergyBuildAdjMod }
            if self.EnergyBuildAdjMod > 0 then
               mult2 = mult2 * self.EnergyBuildAdjMod
            end
            self.EnergyBuildAdjMod = mult2
            self:UpdateConsumptionValues()
         end
      elseif table.find(LowerCostUnits3, UBBBPID) then
         local AIBrain = self:GetAIBrain()
         if AIBrain.BrainType != 'Human' then
            self.EconChangedForIA = true
            self.EconChangedForIAValues = { Energy = self.EnergyBuildAdjMod }
            if self.EnergyBuildAdjMod > 0 then
               mult3 = mult3 * self.EnergyBuildAdjMod
            end
            self.EnergyBuildAdjMod = mult3
            self:UpdateConsumptionValues()
         end
      else
         if self.EconChangedForIA then
            local LastValues = self.EconChangedForIAValues
            self.EnergyBuildAdjMod = LastValues.Energy or nil
            self:UpdateConsumptionValues()
            self.EconChangedForIAValues = nil
            self.EconChangedForIA = nil
         end
      end
   end,
    }
end

The If/Then for "self.EnergyBuildAdjMod > 0" i have insert as i dont know like the engine mult operations again zero ......

Thanks for the Help Domino.

Hi,

as i have now the code working to reduce build costs for AI players (with big help from Domino

) i thinking over if its possible to doing the same for Enhancement costs ?
To clarify, to make the ACU upgrades for AI player cheaper.
But i dont know how i set this up to this ... IF this possible ....
(as i cant use the ACU UID ..... so it musst get other way to set this to an specific upgrade ....)
Any help is welcome

Hi,

Do you ALL ai enhancements to be cheaper or just a select few?

RxTEAM · **Joined:** 02 Jun, 2010 **Posts:** 188

Hi,

just a select few i need cheaper Domino ...
( all enginering updates T2/T3 and combat engenering T2/T3 , as the AI can build with T3 commander allready all T4 blackops units - the AI not need upgrade to T4 )

Hi,

Making just a select few more cheaper for AI is more difficult than making all AI enhancements cheaper, some kinda list has be made to say which ones are cheaper..
and by how much are they cheaper..

however if ALL AI built enh want to be cheaper its a simple function hook i can tell you how to do that.

RxTEAM · **Joined:** 02 Jun, 2010 **Posts:** 188

Hi,

its look its musst the hard way

As, i have an massive upgrade cost changing mod maked.But the AI dont play very well with this ... he dont can handle the higher costs.To change the AI is an very to big project - and i dont know can this be made as smart like an human player play with this high cost and found ways to negate the effect partialy ....
So the easy way was to make the costs for the AI players like default (or around this value) ... but i have changed the upgrade costs for the ACU to higher tech levels too .. and here the AI still spend to much time and sucks ... so the best would be, make here the costs like default too .. as an side effect - the AI can now play much stronger as he have much easyer T2/T3 and Exp units as the Human player ..

So i need to lower the energy/mass costs from the tech level upgrades to T2/T3 on the Black Ops ACU´s for the AI players only.

Thanks for you Help Domino

Hi,

@Domino
How would i make all enhancements to be cheaper for the AI ?

And btw. - i think it is not possible to reduce the energy usage from an Unit only for AI players.
So i musst create an duplicate - can this be done easy (over scripting) or only with an full copy of the unit files ?
And can i hide this new unit from the Human player - so it is only build by the AI(with propper AI integration) ..... ?
