AI Development Guide and M27AI v74 Devlog


Installation notes
To play with M27AI, go to the mods section in the FAF client and search for M27AI. Download the mod, then when hosting a game make sure you have enabled the M27AI mod. This should allow you to then select M27AI as one of the players in the game.

Further details including screenshots on how to setup custom AI are included on the FAF Wiki:

Summary of how M27 plays compared with default/sorian AI
M27 is intended for players in search of a greater challenge than the default/Sorian AI. Some of its features include:

  • Adaptive playstyle, responding to player actions, and actively seeking out vulnerabilities in player forces and building units to exploit these
  • Making use of player tactics/unit microing and certain 'try-hard' type approaches, for example kiting with units, hover-bombing, synchronising MMLs to overwhelm TMD, manual reclaiming, ctrl-King T2 mexes to build T3
  • Being built with FAF balance/meta in mind

To give a couple of examples of the challenge it provides compared to the default and Sorian, 1 (normal) M27 AI has managed to beat an Adaptive and/or Sorian adaptive AiX with a 2.0 modifier, and also beaten 7 Sorian adaptive (on the same team) on Setons, and is consistently the winner of AI vs AI tournaments (although RNGAI is a close second and worth checking out as well since it offers an alternative play style).

M27AI background and status
Following the 2021 Supreme Computer Cup I was inspired to have a go at developing a basic AI for FAF. As I had zero experience of coding in Lua, I thought at the same time I would write down things as I learnt them to have both a guide for other people interested in getting started in developing an AI, and a dev log for the creation of my AI.

See below for a link to the current AI development guide and devlog (2022-12 update - as people were having issues viewing the original file I've split it out and have separated the main 'devlog' part of M27 development from the more general notes on getting things setup to develop the AI and useful functions)
Devlog extracts:
Development guide extracts:

You can also access the mod on Github:
While in theory it should be possible to install the mod by copying the M27AI folder (from Github) into the FAF mods directory, some people have reported issues with that. It's recommended that the mod is installed through the FAF client (via the mod vault).

I've copied the current overview from the guide below:

This document is intended to do 3 things at once (meaning it does none of them very well!):

  • Act as a guide to people new to FAF AI development, including collating any other useful resources out there on AI development
  • Be a sort of dev log of my thought process and development steps for creating my first FAF AI, with extracts of code thrown in
  • Form my main ‘todo’ list for further developments of my AI
    If you see any errors, or have any comments or suggestions (in particular any AI developers who read this since you’ll probably know better/easier ways of doing things than the methods I’ve chosen) let me know and I can update the guide where relevant.

If you’re here for useful resources and/or details of how to write AI and don’t care about the dev log aspect then just skip to section 2) Setup and background and section 5) Index of useful functions, and/or browse the index for points that may be of interest.

Latest changes (v70-74 summary)

V70 summary of changes:
Update based primarily on issues spotted from the first weekend of the Rainbow Cup tournament:

  • Fixed a bug that caused MAA to stay way too far back from the ACU when there were nearby enemy tanks (i.e. the MAA would run away from the tanks even if they were needed to protect the ACU from gunships/bombers)
  • Significantly improved the speed at which the AI will try and get T2 PD if the enemy gets a guncom and attacks its base
  • Added new capture logic to capture certain civilian units on the map (e.g. titans on big bang dry)
  • 6 other bugfixes, and 12 misc changes, mostly relating to building ground based anti-air, and being a bit more cautious with bombers (including not overbuilding them once a very large bomber force has been assembled).
    v71 - 8 Minor bugfixes and tweaks
    V72 - 4 fixes, including AIX fix
    v73 - M28 compatibiltiy fix and energy storage adjust for FAF balance change
    v74 - Minor bug fixes, primarily relating to the mobile factory and Aeon gun upgrade FAF changes

Not exactly an AI comment, but you wanna have things right, right? 🙂

"Lua" (pronounced LOO-ah) means "Moon" in Portuguese. As such, it is neither an acronym nor an abbreviation, but a noun. More specifically, "Lua" is a name, the name of the Earth's moon and the name of the language. Like most names, it should be written in lower case with an initial capital, that is, "Lua". Please do not write it as "LUA", which is both ugly and confusing, because then it becomes an acronym with different meanings for different people. So, please, write "Lua" right!

Thanks, I'll reflect the correct case usage of Lua in the next version of the guide (I'll probably update it whenever I release an AI update so the two are in sync)

So I decided I might actually post something more relevant 🙂

Full stops vs colons – continuing the above example, oUnit.GetUnitId() will return an error, but oUnit:GetUnitId() won’t.

It's maybe worth mentioning why that happens. oUnit:GetUnitId() is syntactic sugar for oUnit.GetUnitId(self). So if you wanna you the version with . you have to pass self as first arg.

F9 opens up the debug window (you may want to change the game resolution to windowed to more easily access this).

That's a log window, not debug. You can open the debugger with Ctrl+F9 or /debug and that's way better for debugging then trying to print things into the log. Since it works as any debugger you are used to, pauses the execution on the line you seleceted and lets you see whats inside global and local variables.

The below link also appears to give a list of core/global functions that can be used (I’ve not tested these to see if they all work, or even if they’re for FAF rather than SupCom2):

It is for FA, some of these functions are documented here

I’m not using Github since I’m working on this on my own, and since I doubt I can get the same ease of use I currently have with changing something offline and instantly seeing the results in-game after a Ctrl+F10 restart. However, Github is used by a number of the AI developers so there’s likely some significant benefits to it.

Git is very useful even if you're working alone, as you have history of changes and you can easily switch to previous versions if something breaks. The game can use files from any location, so for my development, it uses files from my local git repo. It's just a matter of setting your own init file

To keep things simple (as I couldn’t get more complex builderconditions{} with multiple variables to work, despite seeing it being used in other AIs people have done)

So build conditions are defined in a table

BuildConditions = {
    {BMBC, 'BaseEngineersEnabled', {self.BaseName}},
    {BMBC, 'BaseBuildingEngineers', {self.BaseName}},
    {BMBC, 'HighestFactoryLevel', {i, self.BaseName}},
    {BMBC, 'FactoryCountAndNeed', {i, j, pType, self.BaseName}},
    {BMBC, 'BaseActive', {self.BaseName}},

so here, you have 5 build conditions, each in it's own table.

local BMBC = '/lua/editor/BaseManagerBuildConditions.lua'

first value ( BMBC) in the table is thr path the file you wanna use
second one ('BaseEngineersEnabled') is name of the function in that file to use
third ({self.BaseName}) is table of arguments to pass into that function
AI brain is always passed as first argument, and then all other that you specify in the table

So you could rewrite your example to this:

-- Inside the builder
BuilderConditions = {
    {MIBC, 'Is1NearbyMex', {11}}

-- Inside MiscBuildConditions.lua
function Is1NearbyMex(aiBrain, distance)
    local iNearbyMex = MapInfo.RecordMexNearStartPosition(Utilities.GetAIBrainArmyNumber(aiBrain), distance, true)
    if iNearbyMex == 1 then
        return true
    return false

This way you can already specify the distance for chehcking the nearby mexes.

Determine com start position

This function should do the trick 🙂

To help with this, I first wanted to understand what the various variables feeding into it were, so made use of the log function for each variable in turn; where it returned an error due to being a table value that I was trying to put into the log

Best would be to use the debugger to see whats what, as you can open the tables.
But if you really wanna dump the table into the log you have to use LOG(repr(table))

Thanks, in particular for the debug window - I expect using that would've drastically cut my debugging time! I'll update for your comments in the latest version.

Unfortunately I can't get the debug window to work for me (I just get an error message) and some other people have had the same problem. Asking in the AI discord Jip thought that you need to do an install from the cd version of the game not steam but that you may know the exact procedure?

Error message below in case it helps:

unpack this
into \THQ\Gas Powered Games\Supreme Commander - Forged Alliance\coderes\Engine

Don't think I've got that folder with the steam install, I've got the following:
C:\Program Files (x86)\Steam\steamapps\common\Supreme Commander Forged Alliance
(this doesn't have a coderecs folder, and adding one in doesnt resolve the issue)

I've also got the FAF location:
same issue as with the steamapps folder

(just in case I also tried the \Documents\My Games\Gas Powered Games\Supreme Commander Forged Alliance folder but no luck).

Is there anywhere else I may have missed for a steam version?

Although I'd hoped I'd got the CDs for both as well, checking I've only got the CD for the original supcom so cant try a fresh install via disc.

It belong to the game instalation folders, and fast few ppl having this issue resolved it by creating those folders


I am not finished reading your guide, but excellent work so far!

v4 changes (in reality v2, but when I uploaded the mod on its first release I had to rush out a couple of hotfixes where I'd forgotten to remove debug logic and accidently introduced a bug that affected all games!)

  • Fixed various bugs (see 3.14.3)
  • Slightly improved pathfinding performance (see 3.15)
  • New AI logic which will detect enemy threats and send units to deal with them (see 3.16)
  • New AI logic which attempts to maintain intel over the map to stop surprise attacks (see 3.17)

I've also updated the guide to reflect speed2's comments (as well as a couple of other minor points/sections, such as a bit on uploading a mod and some tests that I now run before uploading)

I am stunned.

Really good work, maudlin27!

v5 changes - these were mostly about the ACU, making it more aggressive and less suicidal

  • Fixed various bugs and improved some error handling (see 3.18.4)
    ACU improvements (see 3.19):
  • ACU will try to expand to high reclaim or mex locations, while building on mexes it comes across and reclaiming
  • ACU will have scout and MAA support
  • ACU tries to kite enemies it comes across
  • ACU uses manual overcharge to overcharge optimal targets

Also updated the guide slightly to add details of the AI development discord channel in FAF (separate to the main AI development discord), and a couple of common hard crash errors

v6 Hotfix - My AI broke with the recent FAF patch, so this is primarily to fix that. I was in the middle of more extensive changes so my AI is less stable than I'd like but I figured it's better than a broken one! I've also held off on updating the dev log for this release.

Main changes made:

  • ACU performs better underwater (reclaims units, tries to move to nearby land when it cant shoot)
  • Improvements to ACU overcharge behaviour (it should OC when retreating, and also positions better against enemy PD)
  • Switch to new error handling approach (orange messages now appear in the log with more detail; this also happens when any ACU dies)

Issues currently present I'm aware of (which shouldnt have a noticeably detrimental impact on performance, but will be noticeable to anyone looking at the log):

  • 'MergeLocations' error message on certain maps - should just mean larger platoons dont regroup at a midpoint before attacking
  • 'MexRaider' warning about the final waypoint - in most cases just affects which mexes are targetted (in rare cases might cause a delay in the platoon doing anything)
  • 'Stuttering'/delays in performance on certain maps (e.g. open palms)

V7 Update - T2 is now here! My changes were focused on creating my own engineer and platoon formation functionality (which took far far longer than I was expecting due to various difficult bugs - a lot of work for not much benefit), but at the end I threw in some basic upgrade logic so my AI now gets T2.

Various bug fixes. More notable ones are that the AI should work better on adaptive maps that 'hide' some of their mexes, and should be less likely to try and build on unpathable mexes
Custom platoon formation and engineer functionality. A couple of more notable features of this are that engineers now work together to build 1 building (e.g. power) rather than independently try and build 5 at once, and factor in what mexes theyre already planning to build on when choosing where to expand
Building upgrade logic - AI will now upgrade mexes and land factories (meaning for the first time T2 units can hit the battlefield!)
Load spreading of functionality to help counter the CPU performance hit of these changes
I've also updated the guide for a couple of points (e.g. including a section on events)

As before, much more detail on the changes/my thought process as I went about implementing them is in the dev log.

v8 Hotfix - Fixed a game crash that could happen if the AI lost an upgrading building (thanks to relent0r for for flagging there was a crash), along with a couple of other minor bug fixes.

v9 Reintroduced air units:

  • Air scouts are built to periodically scout locations of interest
  • Interceptors are used to help defend against enemy air attacks
  • Bombers should target enemy units of interest.
  • Air factory should be built early if there's enough power (and by a hydro if one is available)
  • Various bug fixes and small tweaks to behaviour - refer to 3.27.6 - 3.27.7 of the guide

I admire the guide / developers log that you are keeping 🙂

A work of art is never finished, merely abandoned

V10 - Implemented anti-turtle logic:

  • Use of T2+T3 MMLs and mobile arti to break firebases
  • Ecoing (not very well, but better than before)
  • Reduced turtle feeding

Misc changes:

  • Large bomber attack for if we end up with lots of spare bombers
  • T3 air factories can be built/upgraded
  • Support factories will be built/upgraded instead of HQs
  • Higher tier power is built sooner
  • Engineers can request guards
  • Various bug fixes (see section 3.30.2 of the guide)
  • Updated the guide with details on how to run in FAF Develop offline

My AI also has a new icon 🙂


For anyone that's interested in the background to the last 5 versions/2 months - back at v5 I was crushed by gunner1069 (I usually get them to play a match every couple of weeks against the latest AI version) with a simple turtle strategy on Theta Passage - they didnt bother getting any mexes and instead just rushed T2 PD with their ACU and my AI had no answer despite having 4x the mass income. My primary focus in all the versions since then has been coming up with the logic that will give my AI a chance in that scenario.

Unfortunately, a relatively simple plan for a human (dont send units single-file into PD, upgrade mexes and then attack with MMLs) required a bunch of different bits of logic:

  • Checking for PD and running away from it (so the enemy isn't fed kills/mass), without running away when we're already in range of it and able to beat it (I had some frustrating to watch games where my AI would charge in at a firebase, overwhelm the shields, be about to destroy everything, before deciding to run and turning a winning position into a loss)
  • Realising there's PD when it kills our land scouts without being picked up by their radar
  • Making use of air scouts to reveal 'hidden' PD to avoid suiciding units and the ACU into the PD
  • Quickly expanding to uncontested mexes (including on enemy side of the map)
  • Focusing on maintaining map control and ecoing if faced with a turtle rather than trying to break them immediately, which in turn requires various logic for identifying if we're against a turtle, upgrading mexes, building T2+ buildings, upgrading factories, making use of support factories, etc. (I've still not got basic things done like capping mexes with mass storage)
  • Using indirect fire units to attack PD/long range enemy units while both protecting them from enemy mobile attacks, and not suiciding our own units trying to protect them

These changes also mean my AI will be worse in other situations - e.g. against a non-turtle it might choose to eco when it would be able to finish the game by pressing the attack, and it's also still poor at the mid-T2+ stage so extending the game via ecoing means it's more likely to snatch defeat from the jaws of victory. Long term though it needed to happen as a 'T1 or die' strategy only has a decent chance on 5v5 maps.

@maudlin27 Nice list of g
Changes of updates for you Ai mod, I'd like to extend you the offer it have this in a more of a cleaner formate over on the new faf wiki, if this is somtbing your interested in please send me a pm here or on the faf discord and I can set you up with a page 😀
