M28AI Devlog (v228)
-
v186 Update
9 changes, including:- Building T1 engineers on repeat should no longer cause a large group of T3 mobile arti to stay stuck firing at them
- TMD should be built preemptively for large amounts of PD at the T2 stage
- Slightly increased the range for experimentals to aggressively go for a nearby enemy ACU
Acknowledgements
- Radde - Various replays on Xander against v184 M28
-
v187 Update
8 changes, including:- Fixed a bug that meant bombers weren't sniping ACUs most of the time
- M28 should consider sniping enemy ACUs for significantly longer than before
- T1 PD should only 5 wall pieces built around it (instead of
to save a precious 9 mass...

v188 Update
16 changes, including:- Fixed a bug that would break M28's engineer logic if the enemy built T2 arti near M28's base
- LABs should be more aggressive if the enemy has an exposed unit but nearby combat units.
- Units should no longer try dodging shots from snoops or spirits
- Fixed a bug where deceivers would continue to cover an ACU after it's got a stealth/nano upgrade

v189 Update
Mini update:- Fixed a bug where moles could be given the same order as selens.
- MMLs should be less likely to move forwards into range of T2 PD
- Disabled several factory builders for lower tech factories.
- Fixed a bug with the ACU determining friendly AA threat when in the water.

v190 Update
27 changes, including:- Fixed a major bug with M28's air scouts on maps with water
- Improved ecoing for air slot, and slight more general ecoing adjustments
- ACUs and mexes should no longer assume they are safe to get an upgrade just because they are in M28's main base
- Guncom ACUs should be less likely to kite when facing an unupgraded enemy ACU

v191 Update
15 changes, including:- If T3 naval units get stuck they should consider ctrl-king support factories in their way

AI sometimes gives up after initial push.
In the image below, I'm teal. AI is adaptive cheating. It led with a respectable initial attack of about 6 monkeylords and 50 or 100 bricks. After that, it hasn't really done anything, just filled up its unit cap with engineers and a few bricks, and making no attempt to take space.
It's unclear what causes this behavior. In other games on the same map with the same settings, same faction choices, and same spawn locations, the AI consistently applies pressure throughout the game.
To be clear, I've actually been sitting AFK for at least 30 minutes in this game, only checking back in occasionally to see if anything has changed.
-
@Gatorized Do you have a replay? I'd expect it to still be building experimentals
I'm also assuming you have unit restrictions on preventing things like T3 arti, air units, scathis?
-
v192 Update
15 changes, including:- Fixed a bug where M28 would think it had mass to spare when mass stalling in some cases
- Various adjustments to how many factories get built for various AI subtypes
- Made it more likely factories should be ctrl-k'd when stalling mass
- ACUs should be more likely to run when in their main base
Acknowledgements
- Vortex - a couple of v190 replays on QUIET
-
v193 Update
Small update based on an AI vs AI game I ran:- Tweaked the initial build order from land factories and ACUs if the enemy base starts by M28's base (so factories build a few more engineers after the initial labs/tanks, and gets fewer LABs, while the ACU is more likely to stop building and engage an approaching enemy ACU)
- ACUs should consider helping out a friendly ACU that is fighting an enemy ACU over certain other actions such as reclaiming
- Land combat units should help any M28 ACUs in trouble in a nearby zone (not just the zone they're in), and should do this not just if they would be retreating, but also with any shorter ranged units that are protecting their kiting units.
-
v194 Update
Another mini-update (given the upcoming rainbow cup I thought it better to do smaller more frequent updates to reduce the risks of bugs being present at the time of the tournament):- Fixed a bug where M28 could give orders to a non-M28 unit that completed construction of M28's unit (such as a teammate ACU)
- Fixed a bug with AIx 1.5+ modifiers that could break M28's engineer logic
- When building its first 3-4 mexes, M28 should prioritise the mex that would give adjacency to its land factory (hopefully saving a precious 1-5 mass over the course of the game).
- Fixed a couple of errors with QUIET (M28 aggression factor defaulting to 0.9 instead of 1.0, and scenarios involving land experimentals without a direct fire attack).
Acknowledgements:
- Vortex – QUIET replay; mentioning M28’s aggression factor defaults to 0.9 in QUIET
- Aranei – Log highlighting a bug with M28’s engineer logic where it has an Aix 1.5+ modifier
- Fearghal noticing M28 was building a starting mex that wasn’t adjacent to its first land fac in priority.
-
v195 Update
8 changes, including:- Strat bombers should switch to trying to hover-bomb if they fail to launch their bomb normally (e.g. due to cliffs), and should no longer target scouts and LABs
- Fixed a bug with TMD being built (and over-built) for T1 PD
- Adjustments and fixes to ACU retreat logic so it should be more likely to run when in trouble, but also a bit more aggressive when near its base
Acknowledgements
- Chucups - Replay where M28 suicided 2 ACUs into T2 PD
-
v196 Update
11 changes, including:- Fixed a rare crash
- Further tweaks to AI personalities so e.g. M28Air should delay T2 land until it has T3 air in certain cases
- Slight adjustment to MAA so they should stay a bit further away from enemy tanks.
- 3 mod specific changes, involving some redundancies for cases in LOUD where a mex died just after an upgrade was started (causing M28 to never build on the mex again), and a fix so units with built in TMD should no longer get free veterancy intercepting enemy missiles in steam/LOUD/QUIET.

- Tematus - Replay with a bug where M28 didn't rebuild mexes that were destroyed

Hello maudlin27,
I noticed that your AI in the control support function influences the Scry ability of the Eye of Rhianne in such a way that the player cannot control the eye himself even if the M28 support function is deactivated. https://replay.faforever.com/24285869

@Saver Thanks, hopefully should be sorted now but let me know if you have any issues
-
v197 Update
19 changes, including:- Various niche bugfixes
- Various changes relating to overflowing mass due to the unit cap, including reater use of quantum gateways and SACUs, getting SACU build power upgrades more commonly, ctrl-king T3 land and air factories if there are loads of them, and being more likely to build game-enders if lots of mass is stored
- Fixed a bug where disabling unit prioritisation would lead M28 to always build game-ender templates, and could e.g. cause it to build the same unit on repeat
- Hopefully fixed a bug where enabling shared armies mode in game settings would lead to M28 taking control of the Eye of Rihanne regardless of if M28 had been enabled on the unit
- 5 mod specific changes (relating to experimentals with no direct fire attack; t3 bombers firing salvos; and building paragon-like units for non-aeon factions)
Acknowledgements
- Saver - Noting eye of rihanne issue
- Vortex and Azraeel – Replay with various error messages relating to M28
- Wingflier – Replay where M28 failed to build a paragon/equivalent
-
v198 Update
6 changes, including:- Improved logic and bugfix relating to M28's choice of island to drop so it is more likely to drop large mex islands
- Fixed a bug with calculating enemy air threats that would lead to subs running from inties
- M28 should no longer go 3rd land on naval maps in a 1v1

- New logic for strat bombers early on to target enemy mexes and power
- Improved TMD defence against multiple enemy TML
Acknowledgements

We were talking about AI in our games last night and something that came up is that none of the AI know how to play PhantomX. Is this something that you think would be possible in the future? I imagine the simple part is teaching an AI that they need to break if they're the Phantom, but more complex is simulating how they would come to decide who the other phantoms are and who are the innocents.
Just a fun thought. Played a few games with M28 though and watching it kite me out is infuriating. Great job. lol
-
@Doompants I can't think of a straightforward way of making it work. I've not played phantom but my understanding is that every player is hostile, but that 1 is the 'phantom' with a bonus to resources, and you win if you kill them;
in which case the more straightforward options for the AI are either it treats everyone as hostile (which is what I'd expect to happen if you can attack other players), or it ignores units that aren't those of the phantom (which would presumbly make it fairly easy to tell who is the phantom, and also lead to it suiciding units into other players).
