M28AI Devlog (v141)

v128 Update
16 changes and fixes, including:

• Reducing the number of naval factories that get built
• Factored in mobile shields when assessing how strong an enemy naval force is
• Made the naval combat logic more detailed so it is more likely to take into account units that are relatively near it when deciding what to do
• 7 LOUD specific changes, including fixing an incompatibility resulting from the latest LOUD 7.10 release, and fixing an issue that meant M28's ACUs would be overly aggressive.

• c04spoon - replay highlighting various torpedo bomber related issues
• GerJS - Noting that with particular game settings M28 would prevent one of the objectives loading on UEF M6

@maudlin27 It took forever to do the first analysis and every few seconds it froze. no replay, it was unplayable, also ai games don't get recorded, that's why I linked the map name so you could reproduce it. Also, I think the crab is bugged, egg units don't inherit AI status.

@innomen Looking into it this is an issue with how MapGen defines the playable area on such maps (in that it starts with no playble area, which then causes an issue for FAF's navigational mesh logic). Jip's kindly offered to look into it further.

v129 Update

22 changes and fixes, including:

• Increased options for the AIx overwhelm modifier to allow smaller AIx modifier adjustments (+/- 0.05, 0.02 and 0.01)
• Increased cruiser production in certain scenarios to protect from torp bombers
• Fixed a bug where M28Easy would ground-fire subs
• 11 LOUD specific adjustments (including support for bombardment ships, not treating engineering ships like frigates, a bug that prevented M28 recognising when its naval units shots were being blocked by terrain, and some logic that in some cases may have caused desyncs)

@maudlin27 Child units are not inheriting AI status. novax sats sit there, eggs, and fatboy outputs. FWIW

Hi @maudlin27, a few issues I've noticed with M28, usually when using the MOBA mode:

• AI spawns a lot of scouts early on - sometimes dozens. I've had some games where it won't build any tanks for 5 minutes or so (will build AA and artillery though).
• AI will upgrade all mexes from T2 -> T3 at once, causing a massive and persistent mass crash. Could be reclaim related? Eg I collect a bunch of reclaim, the AI queues up mex upgrades, but doesn't pause them when mass flows drop again? See this replay as an example I think: #23420048.
• Aeon AI will get stuck in a loop of building T2 shields, destroying them, then rebuilding T2 (instead of presumably the intended T3). See this replay for an example: #23420639. About 1:10 onwards, near my com in the centre left of the map.

Thanks for your work on this! The new MOBA mode has gotten one of my friends to pick up the game again

@sioloc Thanks I'll have a look, although I'd need a replay re the scouts to see if it's working as intended or not (it likely is, since it relies heavily on intel so prioritises building lots of scouts in the early game; while for Aeon it can also build extra scouts to use as combat units)

I think this was your teammate the first time - M28's logs for upgrading a unit didn't trigger when 4 t2 mexes were started at your teammate's base.
For your mexes, the issue is as a whole your team had lots of T3 mexes, and lots of mass stored (as your teammate had about 3k mass while you had none) - so M28 started upgrading multiple T3 mexes on the basis the mass from your teammate could fund it.
I'll tweak it in the next version so in MOBA mode M28's team resource sharing logic is enabled (which should largely mitigate such issues). It'll still be a problem in non-MOBA teamgames with shared armies though (where a teammate with lots of mass and/or T3 mexes will result in too many of your mexes being upgraded if the teammate sits on the mass instead of sharing). I can't see an easy solution to that though, as in many cases people wouldn't want the 'share resources' team logic to trigger.

Re the T2 shields being destroyed this looks like a problem with its backup shielding logic where a shield that is 99% complete is being completed (when that should only happen when under enemy artillery fire), I'll see if I can fix for the next update.

v30 Update

24 misc changes and fixes, including:

• Improved kiting for frigates/navy generally vs enemy hover and when bombarding shorelines
• Fixed several issues with shared armies where certain units (novax, fatboy) wouldn't benefit from the inherit status game option
• Mobile shields should be less likely to suicide into enemy units
• Asfs should be less likely to suicide into enemy air units at the enemy base
• Fixed a bug for SMD where M28 would always think the enemy had a nuke launcher (and so build a pre-emptive SMD too soon)
• 4 LOUD specific changes, including reducing one of the MML builders where the enemy has TMD

Heyyo Maudin. Thanks to also release the M28 for Steam , but I encountered with one problem . I'm using the Steam FA, with various mods of course + Sorian AI as well, but the UEF T2 Engineering Suite (The Kennel), when built, messes the bottom interface, you can select it, but actually the interface is missing, and I cannot upgrade it, checked the T2 Cybran E.S. The hive, there was no problems with it, neither with the T3 Kennel, only with the T2 one. And it was working properly until I installed the M28. Can you look for some solutions for me ? Cheers: Mr.P. PS: I'm using the latest M28 for Steam what I found on ModDB.

Also the AEON T4 CZAR unit seems to be broken with M28 , because when it finished, opens up and start firing to the ground, because of this, its utterly vulnerable to air and seems idiotic. Also it doesn't seem like to use units from Xtreme Wars, what is my ALL TIME favourite...

@mrphalanx I'll look into the kennel unit to see if I can reproduce and fix the issue for the next release. In respect of the Czar I'm not clear on what the issue is from your description - I'll run a sandbox test to see if there's anything obvious in how it attacks units, but I'd have expected it to be vulnerable to enemy air units (as it's primarily an anti-ground unit)

@maudlin27 Thanks for the answer mate. The problem with the CZAR is that is the AI automatically puts it into planetary annihilator mode (that means when the carrier opens up) right after it built it. And when in planetary annihilator mode, it cannot attack aircraft, the Sorian ai only opens it up when reached an enemy base/ cluster of units...

And I know maybe I'm asking too much, but can't you make at least a M28 -Experimental, what can focus on even T1 Experimentals from the start ? Because now the AI only after reaching T3 starts to build T1 Experimentals slowly (mostly from Total Mayhem, but there is plenty T1 in Xtreme Wars too), almost none of T2 Experimentals, and a ton of T3 Experimentals. Sorian AI does this part mostly properly, the only problem with it that sometimes it even rushes to build a T1 Exp, even to an extent to it forgets to build a proper economy/minimal base defenses.. Your AI is way better at this, but it does a little slowly, okay I did not use the AIX, just the AI(Turtle, Rush, Etc...).

I want to make clear the CZAR problem, I looked into it, when it opens up it still can fire an air unit, that's not a problem, the problem is, when your AI builds it, it AUTOMATICALLY FORCE ATTACK GROUND, so because of this, the unit cannot attack anything other land. Sorian AI has no problems using it properly.

I've not been able to reproduce the Czar issue you mention (even if I activate the total mayhem mod since you mentioned that in your reply), but from the description it sounds like it's broadly working as intended since it's meant to be used to attack ground units rather than air units. So while it might not be optimal (re there being some scenarios where its AA abilities would be good), the difficulty with reproducing it coupled with then the difficulty in having logic that figures out if it wants to have its air to ground attack active vs its AA attack active means it's unlikely to change.

I've fixed the bug with the kennel not upgrading though (will be in the next release).

M28 should build T1 experimental base defences, but I've no plans to have it build other T1 experimental units (e.g. tanks etc.) as M28 is setup on the assumption that engineers can only access experimentals at the T3/experimental stage (not T1-T2) so it'd be non-trivialto add and I'm not clear that it'd have a significant competitive benefit that would justify the extensive recoding required (compared with just getting T2 land or more T1 non-experimental units).

v131 Update
28 changes and fixes, including:

• 8 adjustments for when M28 hits the unit cap, primarily focused on when ctrl-king its T2 units is not enough
• Reduced M28's tendancy to overbuild aircraft carriers
• Engineers should no longer suicide into enemies firing at them that it lacks radar coverage of
• 9 LOUD specific changes (including adding a workaround to allow prioritisation of fatboys) and 1 steam change (fixing a bug with T2 kennels not being upgradable)

• MrPhalanx – Mentioning T2 kennels couldn’t be upgraded in steam
• RD – Bitterwind Crag, Elephant Rock and Mellow Shallows replays against v1.29
• Vortex – Replay vs 1.30

v132 Update
21 changes, including:

• Gunships should group together better, and take into account how successful they've been in the game with engagements when deciding whether to attack
• Fixed some issues with transports that would e.g. prevent them dropping early when dying to inties
• Reduced tendancy to build more factories late-game
• 10 LOUD related changes, including reviewing/tweaking various LOUD focused PRs from Azraeel (covering building more T3 PD, bombers, ecoing more, and changes to unit prioritisations)

• Azraeel - Various pull requests

Thanks anyway, I check the Ai again ..

v133 Hotfix - Summary
11 Changes and fixes, including:

• M28 should no longer try and protect a friendly teammate's core base afer the teammate has been killed and their base destroyed
• Changed how M28 prioitises which zones to request units/give them orders, to take into account enemy buildings (in theory making it slightly more likely to attack undefended enemy mexes over defending a friendly location)
• Fixed a bug introduced in the last version for managing gunships that could sometimes break their logic
• 7 LOUD specific changes, including supporting factory enhancements, and updating the ACU threat assessment to take into account the ACU health and to account for the massively higher mass cost given to it in the blueprint (10k, which is almost 200 t1 tanks)
