How to alter values of unitweights by scripting?

[Ghoustaq]

Ghoustaq - were you using unitwieght to control unit caps ? If so, the proper variable is CapCost.

The mass extractors vision radius can be found in the Intel section - and it is VisionRadius - if it's not there - then it may be being defaulted.

@Sprouto
Yes, I was. Could CapCost be altered in mapscript? I am unwilling to modify any file in gamedata.

Hello Sprouto:
I wrote some codes as below. Can you check them for me? They haven't worked yet.I don't know why

Code: Select all

for UnitID, Intel in __unit.bp do
        if Intel.General.VisionRadius then
            LOG('Unit '..UnitID..' has a value of '..Intel.General.VisionRadius..' as VisionRadius')
            if Intel.CategoriesHash.MASSEXTRACTION * (CategoriesHash.TECH1) then
                LOG('Unit '..UnitID..' is a TECH1 unit. Seting VisionRadius to 25')
                Intel.General.VisionRadius = 25
            end
            if Intel.CategoriesHash.MASSEXTRACTION * (CategoriesHash.TECH2) then
                LOG('Unit '..UnitID..' is a TECH2 unit. Seting VisionRadius to 35')
                Intel.General.VisionRadius = 35
            end
            if Intel.CategoriesHash.MASSEXTRACTION * (CategoriesHash.TECH3) then
                LOG('Unit '..UnitID..' is a TECH3 unit. Seting VisionRadius to 45')
                Intel.General.VisionRadius = 45
            end
            if Intel.CategoriesHash.HYDROCARBON then
                LOG('Unit '..UnitID..' is a TECH1 unit. Seting VisionRadius to 55')
                Intel.General.VisionRadius = 55
            end
        else
            LOG('Unit '..UnitID..' don\'t has a VisionRadius')
        end
    end

Your code looks good - but - to my knowledge - it won't work in a map script - this would be best used in blueprints.lua

The question is, and I'm not clear to answer this one, is -- are the unit blueprints registered before the map script is run ? If not - then it might be possible for the script to execute as part of the map. If the blueprints are already registered (and I think they are before the map script is even considered) then you can't do it from the map script.

map script is used in BeginSession() so that is too late to change bps

That pretty much confirms it. Which only leaves with a few options - either a blueprints.lua that will temporarily change the blueprint values at game start - or a blueprint merge for each of the affected units which would alter their stats before the blueprints are registered for the game.

OK, I got it. the conclusion is that it's very hard to change variables which have been set in _Unit.bps by the means of map-scripting.

the Mex/Cap ratio function works well just in FA, I cannot run it in vanilla.

Yes, my fault

Only FAF has a CategoriesHash (thanks to Hussar)

Use this to create a CategoriesHash for the blueprint:

Code: Select all

            for _, cat in uBP.Categories do
                UnitBlueprint.CategoriesHash[cat] = true
            end

Hello Ghoustaq,

i viewed your script with intel radius and found 1-2 errors

Here is a copy & paste ready script for your MAP_script.lua:
(Vision radius is set to 1 for tech 1 units etc, just for testing)

Code: Select all

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

function OnPopulate()
    ScenarioUtils.InitializeArmies()
end

function OnStart(self)
    EditBlueprints(self)
end

function EditBlueprints(self)
    for UnitID, UnitBlueprint in __blueprints do
        -- If we have no Categories then skip this unit and continue with the next unit
        if not UnitBlueprint.Categories then
            continue
        end
        -- Generate the CategoriesHash for non FAF game
        UnitBlueprint.CategoriesHash = {}
        for _, cat in UnitBlueprint.Categories do
            UnitBlueprint.CategoriesHash[cat] = true
        end
        -- fist check if we have a UnitBlueprint.Intel table, then check if we have a VisionRadius table inside UnitBlueprint.Intel
        if UnitBlueprint.Intel and UnitBlueprint.Intel.VisionRadius then
            LOG('Unit '..UnitID..' has a value of '..UnitBlueprint.Intel.VisionRadius..' as VisionRadius')
            if UnitBlueprint.CategoriesHash.TECH1 then
                LOG('Unit '..UnitID..' is a TECH1 unit. Seting VisionRadius to 1')
                UnitBlueprint.Intel.VisionRadius = 1
            end
            if UnitBlueprint.CategoriesHash.TECH2 then
                LOG('Unit '..UnitID..' is a TECH2 unit. Seting VisionRadius to 2')
                UnitBlueprint.Intel.VisionRadius = 2
            end
            if UnitBlueprint.CategoriesHash.TECH3 then
                LOG('Unit '..UnitID..' is a TECH3 unit. Seting VisionRadius to 3')
                UnitBlueprint.Intel.VisionRadius = 3
            end
            if UnitBlueprint.CategoriesHash.HYDROCARBON then
                LOG('Unit '..UnitID..' is a HYDROCARBON unit. Seting VisionRadius to 5')
                UnitBlueprint.Intel.VisionRadius = 5
            end
        else
            LOG('Unit '..UnitID..' don\'t has a VisionRadius')
        end
    end
end


I tested this also in multiplayer with 2 PC and it is NOT desyncing the game.

If you can lend a hand once more, Uveso:
How would one go about changing specific unit stats? Let's say I wanted, for example, Yolo to have 10k more hp.
What's missing from this code?

Code: Select all

function OnStart(self)

LOG("----- Survival MOD: Initializing game start sequence...");
   ForkThread(Survival_Tick);

   EditBlueprints(self)
end

function EditBlueprints(self)

    for UnitID, UnitBlueprint in __blueprints do

       if (UnitID == 'XSB2401') then      -- Yolona

             XSB2401_unit.bp.Defense.Health = 22000;  -- tried with UnitBlueprint.Defense.Health etc, nope
             XSB2401_unit.bp.Defense.MaxHealth = 22000;
       end           
    end
end

I bet it's something very simple, tried to figure it out by myself from your vision-by-tech-level example, but am not knowlegeable enough to do it
Much obliged!!!!!

As I believe, by the time you get to your OnStart function, all of the blueprints have already been registered and can no longer be altered. Map loading, and any scripts associated with them always happen after the unit blueprints are locked in stone.
