M28AI Devlog (v156)
-
@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
-
There was nothing left, just the ACU. It built a land factory first and then just went around in circles, never building a power gen or a mex. (ACU was in its spawn point with mex spots around it.)
-
What's meant to happen is the land factory builds an engineer, and that engineer builds the power gen and/or mexes. ACU behaviour is expected since it will by that stage of the game should be terrified of anything that moves and wants to just run instead of spend time building anything (unless enemies get near to it where it might attack them).
-
With UEF it works (although the AI tends to build one offensive unit in the land factory before it builds an engineer). With Aeon, not so much: https://replay.faforever.com/23171674

Hey Maudlin,
are there any other differences between the M28 and M28easy other than the "dodge micro" or is the general micro better on M28?
Do you have any experience on what maps the M28 is the most agressive? On the more normal maps, the M28 often stop attacks after T1 and then it starts again with T4.
-
It should use T1-T2 and to a lesser extent T3 on most maps, particularly if 1v1, so I'm guessing it's your particular playstyle that leads it to doing that but without a replay I couldn't tell. E.g. I'd expect if you pick any 5km or 10km (and probably also 20km) map in the current mappool it should be getting T2 land.
M28Easy disables various other micro not just dodge micro (which can now be done separately via game settings as well). For example, air units shouldn't use hover-attacks; units shouldn't kite; it doesn't handle power and mass stalls as well (re pausing and unpausing units), engineers dont reclaim hostile units near them, etc.
