M28AI Devlog (v159)
-
v52 Hotfix
- Fixed a bug where M28 would stop using experimental bombers if it had 2+ (introduced in v50)
- Fixed an oversight with M28's resource sharing logic which would only use absolute values, leading to some teammates overflowing mass while others didn't have lots (where their total capacity differed significantly).
- Improved skirmisher enemy detection logic to include all direct fire enemies in adjacent zones (previously it would only include the closest enemy for performance reasons, but this would sometimes lead to e.g. hoplites running into an enemy guncom and dying)
- Slight delaying in late game eco (mass fabs and quantum gateways) if the M28AI hasn't built an experimental in the zone in question yet.
- Long range enemy threats such as T2 arti should be taken into account when deciding where units should retreat to (to reduce instances where units retreat to a location within range of enemy T2 arti)

Trophies
Introducing a new 'feature' - trophies! The first person to send me a replay for a more recent version of M28 than the current trophy holder, where the replay meets the trophy requirements, will be acknowledged as the winner of the trophy in the next update notes. The two trophies are:- The Radde trophy - Named after Radde who has sent a large number of replays fighting 1.3 and 1.4 resource M28s in recent months - awarded to the first person or team to beat M28 on a 15km-20km size mapgen when M28 has a 1.4 AiX resource bonus (i.e. it can still have 1.0 build rate bonus), with no SIM mods other than M28AI. 1v1 or teamgame submissions accepted (teamgame must have mirrored start positions and equal M28 numbers to player numbers)
- The Sladow trophy - named after Sladow, who beat 1.7 AiX M28 (v39) - this trophy is awarded to the first person to beat a default AiX M28 1v1 (i.e. 1.5 resource and 1.5 build rate cheat modifiers) - i.e. any map, any mod.
Note the requirements for the trophy are subject to change with each release of M28.
v53 Update
Kiting and anti-firebase improvements, including:- 7 Changes mostly relating to trying to have hoplites do better at surviving against an enemy guncom (although the changes should be relevant to mongoose and sniperbots as well)
- Replay 21200371 - 5 improvements relating to enemies setting up T2 arti firebases near M28's base
- Fixed M28 not building navy on the map Sludge (along with 2 other minor changes)
- Replay 21193022 - 7 changes, including improving the speed with which the rear M28 position will get T3 air and fixing a bug that lead to loads of TMD being built
- Replay 21206374 - 6 changes, including TMD being built against Seraphim cruisers+aircraft carriers, and T2 being built against nearby enemy naval threats
- 2 other changes, including having hover/amphibious units in the water retreat back to base rather than to the middle of the water zone they're in
Acknowledgements
- Zhanghm – doing some testing on high memory scenarios to confirm the theory that the variety of units built in a game is likely the biggest factor in memory usage.
- Radde – Land and naval replays, both 1v1 and team games, which highlighted a number of improvements required.
- Fertgl – Screenshot/replay showing a poor choice of rally point by M28 on water for hover units.
- Gatorized – Image referring to M28 not building navy (fortunately I was able to recognise the map from the screenshot, but for future reference a replay ID would make it easier for me to identify the issue).
- Jip - Fixing a bug with the navmesh, being quick to merge a pull request fixing a categorisation bug, and continuing to fix minor FAF lua error messages
v54 Hotfix
- Fixed a bug that would break M28's logic in some cases when faced with a nearby enemy firebase.
-
In the last few weeks or so, we've had a number of games with M28AI result in a complete sim freeze - the UI remains responsive but the game world is completely frozen, with no obvious error messages, Lua debugger windows, etc. I will upload a couple of game.log from sessions where this happened in case helpful.

@sparky222b Thanks for the report, do you have the replay IDs for the games?
-

@sparky222b Thanks, found the cause of the crash (if an M28 T2 arti tries targeting a mobile unit), will fix it in the next update
-
v55 Update
Aside from fixing a couple of major bugs introduced in recent versions, this update was around tweaks to the early-game logic based on Radde's trophy winning replays.- 21233524 - 11 changes, including slight improvements to early build order to try and reduce the tendency of M28 to stall power, and a fix to the logic for building an early bomber (that meant it was built when M28 had low power, instead of when it didnt have low power)
- 21233818 - 14 changes, mostly focused around getting more MML sooner if the enemy setups up a T2 arti firebase near M28's base
- 2 other fixes (fixing a crash caused when T2 arti tried to attack a fatboy, and a bug when M28 would consider building T3 mass fabs)
Trophy awards
- Winner of the Radde and Sladow trophies – Radde – in record time Radde beat M28 with a 1.4 resource mod on a large land map, and then crushed it on winter duel at 1.5 AiX. Will the latest changes prove enough to combat a ‘winter duel T2 arti’ attack, or is M28 doomed to failure?
The current trophy holder will also be recognised in the original post of this forum thread.

Wow, that was really fast! Thank you @maudlin27!

The AI M28 just stood still on the map Twin Rivers - Happen twice in a row; do you have an idea why this is happening?
-
@magge Based on the game log M28AI wasn't loaded. Can you recall how the game was setup?
For example I've seen this error before where you click on the Load presets option in the game lobby (before the game started), or click on a rehost game option, in which case it would load the AI and use the default/easy AI, so it looks like a similar thing.
If you just created a new game from the FAF client, didn't load any presets, enabled the M28AI mod and selected the AI though then I don't know what caused it.
-
Thanks for the info - I will forward it to the host player Bash1990 and hopefully he can redo his hosting settings, maybe there was something faulty.
Edit: @maudlin27 He has reinstalled the AI mod and made his lobby settings default - And it is working now.
-
Thanks for confirming!
-
v56 release
More replay focused changes, mainly for dealing with nearby enemy firebases and naval production- 18 Changes relating to winter duel replays to try and get MML faster and attack more aggressively with them
- 9 Changes mostly relating to navy from a mixed mapgen map to try and increase the build power assigned to navy when it's contested, including building torp launchers and subs
- Refinements to T2 arti targeting so they choose their target a couple of seconds before firing (instead of 20 seconds)
- 4 other fixes, including an infinite loop that could happen in some late-game scenarios
Trophy awards
Radde was lightnig fast again with replays securing the two trophies:- Radde Trophy - Radde
- Sladow Trophy - Radde (beating a 1.7 AiX M28 on winter duel)
I'll adjust the trophy awards slightly going forward - the trophy will now to go the highest AI modifier beaten under the trophy requirements for the latest release of the AI (AiX for Sladow trophy, Resource modifier for Radde trophy); where multiple people beat it at the same modifier, it will go to the first person to beat it at that modifier.
I'll also try to keep the original post updated with the current trophy holder (i.e. ahead of the next version release)

v57 release
Campaign and replay related changes-
Added a new 'no rush' type feature to the hostile campaign AI if it 's using M28 - you can now specify in game options how long it will be before M28 applies most of its logic (including attacking). This is to help make some of the missions where the AI starts with a huge army no longer impossible:
-
3 fixes for Aeon M3 so M28 works as a hostile or allied AI
-
9 changes based on Radde's trophy entry (beating M28 1.4 on a naval map), including reduced ecoing so that more resources can be spent defending against navy
-
2 changes on Winter Duel (Sladow trophy entry) so more T1 arti get built and tanks should wait longer before attacking the enemy ACU
-
3 other changes, including adding a threshold for torpedo bombers to be built so the enemy doesn't trigger an emergency response when sending a single engineer across the water
Trophy awards
- Radde trophy - Radde and KuhwaKlimakleber - 1.4 resource 2v2, naval mapgen map
- Sladow trophy - Triangleleaf - 1.8 AiX Winter Duel
-

Played 2 matches on Adaptive Ben's Turtle, AI played much better the first time despite bumping the build/resource mulitplier to 1.5 from 1.4 for the 2nd match.
1st match: https://replay.faforever.com/21295565 4H vs 2AI (Aeon/Seraphim, 1.4x)
2nd match: https://replay.faforever.com/21307459 4H vs 2AI (UEF/Cybran, 1.5x) <- expected this race combination to be much harder. -
@ender06 Thanks, unfortunately both replays desync for me the moment the game starts, but if you play any further games let me know as there's a chance the replay for them won't desync.
-
v58 Update
- 21301510 Mapgen replay - 6 changes, including making M28 slightly harder to snipe with air
- 21301625 – Winter duel - 7 changes, including making better use of very high resource modifiers
- 21305751 Mapgen - 5 changes, including fixing some issues with fatboys and T2 arti. T2 arti should now be built across the map in some cases (which will likely make things a bit worse and need toning down in a future release)
- 21306326 Mapgen - 4 changes focused on improving MML use against enemy firebases
- 21306893 Naval mapgen - 3 changes, mostly improving how M28 handles HARMs
- 21310805 Mapgen - 2 changes to increase engineer production and mex assistance where multiple mexes are upgrading
- 8 other changes, including having M28 eco less; then having M28 eco more; and stopping M28 trying to get adjacency from non-M28 teammates
Trophy awards
- Radde trophy - awarded to Triangleleaf for beating M28 with a 2.8 resource modifier
- Sladow trophy - awarded to Triangleleaf for beating a 2.2 AiX M28
