M28AI Devlog (v328)

maudlin27

v324 Update
8 changes, mostly relating to SCTA, including:

Adjusted SCTA build order to build wind turbines, and prevented mine layers being built
SCTA T2 tactical nukes can be fired by M28
Added a limit on how long transports should wait to load more engineers before moving out
Low mex map logic shouldn't be applied to sub-5km maps that have more than 2 mexes per player

Acknowledgements

Malitarh - replay on sub-5km map where M28 played poorly (note I need access to the other replay where the ACU was locked in an upgrading-cancel upgrade cycle to look into that issue)

Malitarh

@maudlin27 , Perhaps this wasn’t obvious. I have already sent the replay you were interested in. This is a link to Google Drive in this message:

Something was wrong with the FAF, but here’s the replay file — it’s working.
https://drive.google.com/file/d/1pFA9iAgP0QiZyQMGo8L0rIm4pHrFsPk0/view?usp=drive_link

Sorry, it’s not available on the FAF server. Only as a local file.

maudlin27

@Malitarh I don't have access to the replay file (I requested access to it at the time)

Malitarh

@maudlin27
I’ve opened access. Sorry, I very rarely use Google Drive. In many other services, copying an open link already changes the file status to “open to everyone via the link.”

maudlin27

@Malitarh Thanks, checking the replay the enemy AI kept trying to TML M28's ACU when it was upgrading, so it'd cancel the upgrade and move the ACU when it could see the TML missile approaching. However I can refine slightly so it considers if it has TMD that will block the missile.

Mass storage not being built would've been that M28 didnt have many engineers in its core base as it was focusing on building units since its base was under near-constant attack (and those engineers it did build had more urgent issues to deal with), but I'll look at having T2 land factories build a few engineers even where it has a T3 HQ if it's lacking storages for a t3 mex.

maudlin27

v325 Update
7 changes, including:

M28 should try and build its first/main naval factory with more clearance around it so it's less likely to have T3 units get stuck
Fixed a bug with the land combat logic that was double-counting enemy threats in some cases leading to M28 being over-cautious (when not able to kite the enemy)
Land factories should build more engineers if M28 has a T3 mex in the zone without mass storage
ACUs should consider if they have TMD coverage before cancelling an upgrade when spotting an incoming TML missile

@chris12 Do you get the issue with just M28 (and no other mods) enabled (e.g. it looks like a couple of other sim mods are enabled as well from that log)? And if so, does it load fine without M28 enabled at all?
Also enable the FAF debugger as it may give more information in the log to help figure out the cause and/or be of help if you post to the technical support forum in discord

v326 Hotfix
Fixed a bug introduced in the last version relating to naval factories

Malitarh

Hello!
I found two more exotic maps where the M28 is significantly weaker.

The Flat map. No terrain, no trees or rocks, 1 mex per player, huge open space. I consistently win under these conditions. Here’s a replay with the latest version of the M28. https://replay.faforever.com/27913558
The ACU Lab 1 map. No resource sources, 5x5 km, 8 players. I played 4 vs 4, all AI — M28. If there isn’t a random massive attack on me while I’m upgrading the ACU to T2, my team will win. Perhaps the tactic for 4 players should be to upgrade one of them to T2 while the others defend and share resources — which is exactly what I managed to do. Here’s the replay of that battle:
https://replay.faforever.com/27913954

P.S. Was there any change related to distancing from exploding objects, such as reactors, if they are planning to explode?

Malitarh

I got curious. I took advantage of the discovered weakness to defeat the AIX M28 and meet the requirement for the Sladow trophy.
https://replay.faforever.com/27914091

Moreover, Flat meets the requirements for the second award. But right now I don’t have enough time, and I’ll need several attempts.

I decided to review these replays myself and found that they cut off on the server, and only the local file contains the full version of the replay. I’ll write to Discord and ask why this happens regularly. Maybe it’s because of playing with bots? So I’ll post the local files for each battle here so everyone can see them in full:

27913558: https://drive.google.com/file/d/10C1GUIyGMwyNuqS4kFKySsv3lzRq_NSm/view?usp=drive_link

I found out that when launching FAF locally, replays are not recorded and cannot be saved. I apologizing for any time that may have been wasted, as I was sure that match 27914091 was a victory over AIX-M28, but in fact it was the previous one, which ended due to an accidental indication of ACU movement.

At that time, I couldn’t launch the game on the server. And, accordingly, the local game simply wasn’t recorded.

I deliberately launched the game again under the same conditions and roughly repeated the tactic, but this time on the FAF server.

Replay 27948977. The version on the server keeps breaking somewhere in the middle, so I’m sending it again via Google Drive:

maudlin27

@Malitarh For future reference if playing offline then the replay should be saved as LastGame.SCFAReplay against your profile name (I don't have the normal location to hand though as I use linux now, but it's probably ...Documents/My Games/Gas Powered Games/Supreme Commander Forged Alliance/replays/[Profile name])

maudlin27

v327 Update
19 changes, including:

Various adjustments to M28's approach to low mex map to add a bit of variety to the initial build order and greater aggression
Fixed a bug relating to where to place a PD (which could cause issues on some more unusual maps with narrow pathable areas)
Adjusted land scout logic so the first land scout in a zone should support longer ranged units in that zone instead of moving to a different zone.

Acknowledgements

Marlitarh - Replay on a map with 0 mexes which highlighted a flaw with M28's assumption it'd have at least 1 mex to upgrade in a game

Trophy award

Marlitarh - for beating M28 1.5 AIx on a no mex map (assumed - the replay stopped before the end and I was on linux at the time so couldn't run the local replay uploaded, but it was clear from the replay that M28 was headed for a likely loss)

Malitarh

Here, I reproduced the error that was previously observed. The situation begins at 42-43 minutes. M28-Easy is persistently conducting artillery fire on the hill with the “Fatboy” cannons.
This has happened before as well, through the main part of the mountain, when someone tried to shoot at my main base.
https://drive.google.com/file/d/1BhLHxx5RMohUgLjZHwm99UjJ3Dp7lpzH/view?usp=drive_link

And here, a victory is achieved over the new version 327 on the same map (ACU Lab 1) 2 vs 2. In addition to the fact that this is a trophy, there is an error related to shooting at the ACU Cybran obstacle at minute 8. Although the situation is different, it seems this is a different bug.
Battle #27981000
https://replay.faforever.com/27981000

maudlin27

@Malitarh Not sure I understand your first point. Is it that the fatboy is firing at something that is blocked by a cliff? If so then this can happen, as unless M28 is comfortable there is almost no threat it will be cautious with the fatboy and not want to move it closer to a target

Malitarh

@maudlin27 ,
Yes. The first sentence states that Fatboy often fired at targets behind the rock. It seemed to me that this was a logical error, because it was possible to shoot at the object from maximum distance if you positioned yourself at a different angle. In the video attached to the previous message, he could have moved to the right while remaining under the cover of his units.

But I understand that sometimes it’s better to try to break through the rock or just stay at a distance than to get closer.
