How to make the unitcap related to the number of mass-ex?

[Ghoustaq]

I want the unitcap related to the number of the mass-extractors that I own. For example, when I build or capture a mass-extractor, the unitcaop adds 2, if I lose one , it reduce 2. I have no idea to realize it by scripting. I think I need some
technical support from this forum.

Hello Ghoustaq,

You need the following commands:

To get a list of all your massextractors:

Code: Select all

MassExtractorUnitList = aiBrain:GetListOfUnits(categories.MASSEXTRACTION * (categories.TECH1 + categories.TECH2 + categories.TECH3), false, false)

To count all extractors inside the list:

Code: Select all

count = table.getn(MassExtractorUnitList)

If you want to know the actual unit cap of your army:

Code: Select all

currentCap = GetArmyUnitCap(brain.index)

And to set a new unit cap:

Code: Select all

SetArmyUnitCap(brain.index, newCap)

truly grateful for your help！Master!

hello！Uveso：

I wrote a segment of the script.lua as below:

local tblArmy = ListArmies()
for index,army in tblArmy do
local MassExtractorUnitList = tblArmy:GetListOfUnits(categories.MASSEXTRACTION * (categories.TECH1 + categories.TECH2 + categories.TECH3), false, false)
local count = table.getn(MassExtractorUnitList)
local currentCap = GetArmyUnitCap(army)
SetArmyUnitCap(army, count/0.5)
end

Unfortunately， it doesn't work in my skirmish map. Can you check it? I'm sure there is something wrong with it 'causeI am not professional in scripting.

Hello Ghoustaq,

well it's hard to see whats going wrong if i can't see the whole script.
Here an working example, ready for copy + paste to your MAP_script.lua:

Code: Select all

local ScenarioUtils = import('/lua/sim/ScenarioUtilities.lua')
local ScenarioFramework = import('/lua/ScenarioFramework.lua')

function OnPopulate()
    ScenarioUtils.InitializeArmies()
    ScenarioFramework.SetPlayableArea('AREA_1', false)
end

function OnStart(self)
    ForkThread(MexWatcher)
end

function MexWatcher(self)
    -- Set variables to local use only.
    local MassExtractorUnitList
    local MexCount
    local CurrentCap
    local NewCap
    while true do
        -- Loop over every Army in this game
        for INDEX,BRAIN in ArmyBrains do
            -- Get all Extractors owned by this Brain (Army)
            MassExtractorUnitList = BRAIN:GetListOfUnits(categories.MASSEXTRACTION * (categories.TECH1 + categories.TECH2 + categories.TECH3), false, false)
            -- Reset the MexCounter
            MexCount = 0
            -- Loop over all extractors inside MassExtractorUnitList
            for index, extractor in MassExtractorUnitList do
                -- Is the extractor completed (or still in build)
                if extractor:GetFractionComplete() == 1 then
                    -- OK this extractor is finished and will count for the armycap
                    MexCount = MexCount + 1
                end
            end
            -- Get the current UnitCap (We don't need the value (CurrentCap) except for debugmessages)
            CurrentCap = GetArmyUnitCap(INDEX)
            -- Calculate the new unitcap. (extractors * 10)
            NewCap = MexCount * 10
            -- We need at least a unitcap of 2 to build the first massextractor. (Commander + new Massextractor = 2)
            if NewCap < 2 then
                NewCap = 2
            end
            -- Set the new unitcap
            SetArmyUnitCap(INDEX, NewCap)
            -- DebugMessage to the [F9] DebugWindow
            LOG('* MexWatcher: Army('..INDEX..') has ('..MexCount..') Extractors. - Set unitcap from ('..CurrentCap..') to ('..NewCap..')')
        end
        -- Wait a second before we loop again. (if you don't wait here, the game will freeze in a deadloop)
        WaitSeconds(1)
    end
end


The script will print debugmessages to the logwindow (open with [F9]) like this:

Code: Select all

INFO: * MexWatcher: Army(1) has (0) Extractors. - Set unitcap from (625) to (2)
INFO: * MexWatcher: Army(2) has (0) Extractors. - Set unitcap from (625) to (2)
INFO: * MexWatcher: Army(3) has (0) Extractors. - Set unitcap from (625) to (2)


This should push you in the right direction

WOW! It's really working! Thanks very much for directing me. By the way, I suggest modifying "NewCap = MexCount * 2" to "NewCap = MexCount* 2 + 2" so that the NewCap will not be less than 2.

You can also use the LUA function math.max.

Math max is using the highest number from all given args:

Code: Select all

math.max( 2, 0 ) = 2
math.max( 2, 1 ) = 2
math.max( 2, 2 ) = 2
math.max( 2, 3 ) = 3
math.max( 2, 4 ) = 4


So we can use this to get the unitcap:

Code: Select all

math.max( 2, NewCap )

Now we can build the following optimized code:

Code: Select all

SetArmyUnitCap(INDEX, math.max( 2, NewCap ) )

This way you will have always a minimum cap of 2.
