M28AI Devlog (v156)
-
@zhanghm18 The reason for preferring t3 air over t3 land when reaching the unit cap is the time from production to combat is much lower for air, so it ends up being a better use if the unit cap (eg you could probably build a gunship, attack the enemy base, lose it, and repeat 2 more times in the time it would take a brick to move to the enemy base and die)
-
v119 Update
18 changes, including:- New game option to disable M28's unit prioritisation logic (that e.g. means after a few LABs it builds tanks; or after a few loyalists/titans it builds bricks/percies) - so e.g. @zhanghm18 you should see more variety of units when you have the unit mods enabled
- New game option to disable M28's dodge micro (for those who dont want to turn off all micro per M28Easy)
- M28 should try and build SAMs and protect them with a shield if faced with an enemy ahwassa (if it has too few asfs)
- Reduced the extent to which M28 should be aggressive with units where the enemy has vulnerable buildings to stop cases where it could cause fatboys to ignore a nearby enemy megalith
- 10 LOUD related changes, including more unit prioritisations (e.g. t1 sniperbots shouldnt be built), reducing tendancy to upgrade hydros that are near the frontline, starting the first t2 mex upgrade earlier, and increasing the land to air factory ratio

@maudlin27 Thank you! I'll try the latest version later
-
@maudlin27 Tried it out and the new option is very good! I saw a lot of mod units that had never been built before on the M28.More AI options are a really good idea. We can restrict more of the AI's behavior based on how we like to play the game, which is fun!
But the V119 seems to break cybran's experimental shield logic. cybran doesn't seem to be building experimental shields at all now.
Maybe have the AI build an experimental shield for every five normal shields built (at high resources). Maybe this will ensure that the experimental shield doesn't go unnoticed by the AI?
But I do see AI building some experimental buildings in mods (such as experimental power Generators)
In addition, I found that the AI still seemed to build engineers repeatedly and self-destruct (in the case of high unit cap occupation, but the enemy's long-range artillery destroyed the AI's shield), it seemed that the AI wanted to build more engineers to replenish the shield on the one hand, and wanted the self-destruct engineer to save the unit cap on the other hand -
@maudlin27 Thanks again for your ongoing development of this great AI. Just played a game against the latest version. If you like and have a look at replay #23108870 from 51 mins on. The AI does strange things/nothing to recover from a situation where it has lost all energy generators.
Surely an exceptional case and probably something not in your key focus. But maybe there is an easy fix to this behavior?

Thanks for the new info for updates. Not sure if this is related to the update, but during a game it looks like there was an error.
If it's of any help, can post some error info here.

@lightwire Could you post the replay ID? The 'error running lua script' message is something I could look into.
@Hammi I'll have a look but if all of M28's power was destroyed then it's not something I'm likely to be able to solve - it should already prioritise building more power in such scenarios, but as the game will be lost if the opponent has killed all of its power, there's a limit to what I can do (without either negatively impacting its normal logic, or further complicating already cpu intensive processes for pausing units when stalling energy)
@zhanghm18 I can't think of a change in 119 that would've impacted on building experimental shields. If the shields are the same size as normal shields, M28 has great eco (including energy), only has Cybran on the team, and is building scathis and/or t3 arti I'd have expected it to build some.
For the engi self destruct this is likely a consequence of two competing systems fighting each other for which there isn't really a solution - i.e. it wants more engineers to spend its mass in high eco scenarios, but if it has got rid of all its T1-T2 units and has lots of engineers it will ctrl-K some of its t3 engineers (prioritising those without orders) to free up its unit cap, although I can probably mask the problem slightly more -

I just find it interesting that the AI doesn't actually start again from scratch by building power. It just builds a factory and then sits there.
-
Unfortunately the replay desyncs around 26m so I can't see for sure what the circumstances are. At a high level, I'd expect if all factories are destroyed the ACU should try and build a new land factory; if there are engineers they should build power as a high priority; if there are no engineers, the factory should build some. The exception would be if there are enemies near the factory/engineers.
In the desynced version the ACU was trying to build a t1 land factory first which is in line with what I'd expect, but was hampered because of the energy drain from its T3 mexes. However, adding a fix for this (pausing T3 mexes) could cause its own problems elsewhere since it's very rare to want to do this.
-
@maudlin27 I think that's the reason for the problem. The experimental shield in the MOD is larger than the normal shield SIZE. This resulted in M28 not building them.
It should be noted that I remember that the M28 built these larger experimental shields in previous versions. But the problem started with some recent version (sorry, I'm not sure which one). -
Sure. After the game crashed, It didn't show the reply right away in the replay list.
I think this is the one.

Thanks, the 'table index is NaN' error message looks like an issue with the map where a building got destroyed off-map/something strange happened (as the position of the building in the engine shows as an infinite value), I'll add a check for that in the next update so it doesn't cause a bunch of error messages with M28's logic.
Don't know if it would have contributed to the crash or not; I'd have thought it plausible lots of error messages could make a crash more likely, but my change won't necessarily help that as the unit mods being used were generating lots of error messages themselves prior to that point.
-
v120 Update
19 changes, mostly relating to minor bugfixes, including:- New asf/intie hover-micro to increase DPS when targeting slower enemy air units such as transports
- New higher priority T1 and T2 radar builder where M28 has a significant force of longer ranged units that lack radar coverage
- Fixed an issue for water zone assignemnt in the small area surrounding an island that led to some strange zones on white fire
- 4 LOUD/mod changes, including support for upgradable t2 pgens, and observation satellite

-
@zhanghm18 No, I've no plans to support construction of shields that are larger than the normal size
-
maudlin, I've tried to generate a replay showing the ACU doing nothing except for running in circles when the ACU is the M28's only unit in the game. Replay #23151227
I've deactivated all mods except for M28, Total Mayhem, and Black Ops. I hope this one works without desyncs. The interesting part starts around 00:50:00. -
@hammi Thanks, looks like an issue where if you kill its part-complete land factory when it's trying to rebuild its base and it has no other factories it doesn't try and rebuild it, it'll be fixed in the upcoming release
-
v121 Update
Special logic for selens added, along with 14 other changes:- Selens should try and hide near enemy mexes to ambush unsuspecting engineers
- Fixed various bugs, including one that would break M28 on Dawn (FA mission 2), and a bug with its T1/T2 radar construction logic that could break its engineer logic.
- Increased the proportion of tanks to get relative to T3 mobile arti if M28 gets lots of T3 mobile arti
- 8 LOUD related changes, including stopping building experimental resource generators if it has one, unit prioritisation adjustments, T2 sniperbot enhancement upgrade, prioritising cheaper experimentals over expensive ones, and fixing a bug that meant M28Easy (non-AIX version) wouldn’t work.

Thanks, Maudlin. The AI now reliably builds a single land factory after losing its base. But then, nothing happens. Replay (again with some mods enabled, hopefully without causing desyncs): https://replay.faforever.com/23163222

Unfortunately the replay desyncs for me so I can't investigate. If I was to guess, it's got T3 mexes left over but no pgens and so is stalling power
