M28AI Devlog (v302)
-
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

- Radde – Various v187 replays on Xander
- LoneSheep – screenshot showing M28 building sonar in strange places
-
v191 Update
15 changes, including:- If T3 naval units get stuck they should consider ctrl-king support factories in their way
- Tempest should now be given orders as though it's a battleship rather than a submarine
- MMLs should consider firing at stationery enemy MMLs as a high priority
-
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.

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)

- Vortex and Azraeel – Replay with various error messages relating to M28

-
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
Acknowledgements

v199-200 Updates
12 changes, including:- Strat bombers should no longer target t1 units
- New logic for strat bombers early on to target enemy mexes and power
- Improved TMD defence against multiple enemy TML
Acknowledgements
- Azraeel – Mentioning that M28 planned bomber changes were giving strange results
- Fearghal – Noticing tooltip errors for M28, and M28 not working on swamp land city
- Chucups - Replay where M28 lost to large numbers of TML

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). -
v201 Update
9 changes, mostly based on yesterday's rainbow cup games, including:- Improved early T1 bomber so the ACU is less likely to build the air factory ontop of itself, and the bomber is more likely to try killing other engineers even when low health
- If the nearest enemy base is killed but their ACU escapes, M28 should reassess where the nearest enemy base is
- Land experimentals should be more cautious based on the enemy's global air threat, even if it doesnt detect any nearby air threat
- Made the temporary map-wide vision at the start of the game (to tell the AI where civilians are) take place earlier and for less time, so human teammates should no longer get to see if an opponent is going first air.
- MAA should be more likely to take into account enemy tanks that are in an adjacent zone and almost in range of them (so less likely to suicide into them).

V202 Update
23 changes, including:- 3 more changes from Bosem Valley RC games (including that strikers should be more likely to attack with auroras than to shadow them; tanks should be more likely to attack when the ACU is in combat)
- 8 changes from Adaptive Kusoge RC games (including if the enemy tries hiding their ACU on a transport or in water M28 should, when in a dominant position, try killing them; ACUs with advanced nano should be more aggressive; removed code that would result in a land factory being built if an air factory was currently under construction)
- 7 QUIET specific changes, including fixing some late-game issues with factories getting stuck in a cycle of constant enhancements, and multiple paragons being built in the same arti template area)
- 5 more general changes, including expanding M28's ACU snipe logic so if an ACU is near-death underwater M28 should consider sniping with torp bombers.

V203 Hotfix
Mini-update to fix a couple of bugs agead of today’s Rainbow Cup:- Fixed a bug from v202 with M28’s ‘attack ACUs hiding in water’ logic
- T2 navy should be got sooner if enemy has t2 navy
- Fixed a bug that could cause frigates to suicide if the enemy had a submarine
- ACUs should try and stay slightly closer to a stealthed ACU they’re attacking
Acknowledgements
- Radde - mapgen replay
-
v204 Update
Small update for a few changes from the Swamp City Redux rainbow cup semi-final game that I had time to put through, with 7 changes, including:- If a teammate's ACU dies in full-share, and later loses their base, M28 should no longer treat that base as a safe location to run to (and so should be less likely to suicide into Wifi and an army of tanks...)
- Various adjustments relating to certain AI personalities, including increased use of PD for turtle AI, and decreased use of factories
- Certain AI personalities should no longer adopt a 'spam T1' approach to the game even if they had a teammate who was adopting such an approach and died
