Units fire red lines (instahit)

Hello CSI,

How to: Creating custom unit scripts for Sorian AI:
http://forums.faforever.com/viewtopic.php?f=41&t=14688

It's also working with the normal AI in FAF

[CSI]

Oh very nice, so if I understood correctly, the file name can be anything, only the platoon names are considered by th game ?

And I guess we cannot extend the platoon list unless we make a new version of Sorian ?

[Uveso]

Yeah you can use as filename what you want, but as you said, the platoonnames are fixed.

And sure we can add platoons or something else. This has nothing to do with the sorian mod.

I am actual working on my own AI, so i can add/test what you want

[CSI]

Cool ! But right now I can't fit every unit in the default platoons, for example UEF t1 arti. I have the t1 gatling PD in T1GroundDefense already so how do I do ? :/

[Uveso]

Well i am not sure, but the T1 Land arty has already its own platoon (T1LandArtillery) ?!?

See file LandPlatoonTemplates.lua:

Code: Select all

PlatoonTemplate {
    Name = 'T1LandArtillery',
    FactionSquads = {
        UEF = {
            { 'uel0103', 1, 1, 'Attack', 'none' }
        },
        Aeon = {
            { 'ual0103', 1, 1, 'Attack', 'none' }
        },
        Cybran = {
            { 'url0103', 1, 1, 'Attack', 'none' }
        },
        Seraphim = {
            { 'xsl0103', 1, 1, 'Attack', 'none' }
        },
    }
}

This is called from AILandAttackBuilders.lua:

BuilderGroupName = 'T1LandFactoryBuilders',

Code: Select all

BuilderGroup {
    BuilderGroupName = 'T1LandFactoryBuilders',
    BuildersType = 'FactoryBuilder',
    # T1 Artillery, built in a ratio to tanks before tech 3
    Builder {
        BuilderName = 'T1 Mortar',
        PlatoonTemplate = 'T1LandArtillery',
        Priority = 830,
        BuilderConditions = {
            #{ UCBC, 'LocationFactoriesBuildingLess', { 'LocationType', 1, 'INDIRECTFIRE LAND MOBILE' } },
            { UCBC, 'HaveUnitRatio', { 0.25, categories.LAND * categories.INDIRECTFIRE * categories.MOBILE, '<=', categories.LAND * categories.DIRECTFIRE * categories.MOBILE}},
            { UCBC, 'FactoryLessAtLocation', { 'LocationType', 1, 'FACTORY LAND TECH3' }},
            { IBC, 'BrainNotLowPowerMode', {} },
            { EBC, 'GreaterThanEconEfficiencyOverTime', { 0.6, 1.05 }},
        },
        BuilderType = 'Land',
    },
}

------------------------------------------------------------------------------------------------------------------------------------------------------------

T1LandFactoryBuilders is also building other units, so if you want to make a Platoonbuilder with only arty you can add its own Builder.

To do so, create a new file "T1ArtyBuilders.lua" inside the directory "\lua\AI\AIBuilders".
Paste this into the new file:

Code: Select all

local IBC = '/lua/editor/InstantBuildConditions.lua'

BuilderGroup {
    BuilderGroupName = 'T1ArtyFactoryBuilders',
    BuildersType = 'FactoryBuilder',
    Builder {
        BuilderName = 'T1 Mortar',
        PlatoonTemplate = 'T1LandArtillery',
        Priority = 1200, -- changed for testing, original value was 830
        BuilderConditions = {
            { IBC, 'BrainNotLowPowerMode', {} },
            { IBC, 'BrainNotLowMassMode', {} },
        },
        BuilderType = 'Land',
    },
}



Now you need to add this BilderGroup to any AI that should use it.
Go to the directory "\lua\AI\AIBaseTemplates" and edit every lua file (TechMain.lua, RushMainBalanced.lua etc.)
Add the BuilderTeplate for "T1ArtyFactoryBuilders":

Code: Select all

BaseBuilderTemplate {
    [...]
    Builders = {
        [...]
        'T1ArtyFactoryBuilders',
        [...]
    },

Now the AI will spam T1 arties like hell

Oh but I'm not talking about mobile artis, but the building added by Total Mayhem, so it's built by engis and not in the factory

[Uveso]

Ah i see.

Well thats easy

If you need to add more customunits to the same buildplatoon like "T1GroundDefense", then you need more then 1 lua file.

Create a lua file named "XYZ_file1.lua" inside the "\lua\CustomUnits" folder and paste this into the file:

Code: Select all

UnitList = {
   T1GroundDefense = {
      UEF = {'brnt1expd', 40}, -- Name: Mayor MK1 - (Experimental Gatling Defense System)
   },
}


Now create a second file named "XYZ_file2.lua" and paste the other unit in:

Code: Select all

UnitList = {
   T1GroundDefense = {
      UEF = {'brnt1exart', 40}, -- Lumberjack (Experimental Artillery Installation)
   },
}


Both units have a buildchance of 40(%).
If the AI decides to build a T1GroundDefense now, it will be to 40% the Lumberjack, to 40% the Mayor and 20% the original T1GroundDefense from the maingame.
If the AI decides to build a T1GroundDefense now, it will be to 20% the Lumberjack, to 20% the Mayor and 60% the original T1GroundDefense from the maingame.

Just to be correct, the way the AI selects a custom unit is not quite as direct as that.

When there are custom units, the code generates a number between 0 and 100 and if that value is equal to or less than the value on the custom unit, then the AI will select a custom unit.

So if there is only one custom unit, it's true - the 40 will mean 40%.

However, if there is more than one custom unit at 40, then either one may get selected.

If you set your custom unit value to 100, it will always replace the stock unit.

Thanks Sprouto!

I updated the post above to 20/20/60 buildchance.

[CSI]

What if I set 60 and 20 ?

Hey Uveso can you tell me more about the AI you're working on ? :v
