AI-Uveso (v98) - AI mod for FAForever

1

Hey @Uveso

It seems I am having trouble using with Nomads. Is this a known incompatibility? Upon ACU drop-in (when playing as Nomads), the mass and energy seem to go nuts. Along with this, the commander starts out with the t3 build suite and it does not produce a crash or any error. This only occurs when Uveso is active, even if there are no AI's in the match. This does not happen when playing as any other faction. It is the only mod active. Nomads works fine when no mods are active. Tried this on multiplayer with a friend and there is an immediate desync. He also has this issue in solo games as well. Any help would be appreciated since I love both the uveso AI and nomads for high cheat level challenges.

Thanks! If you need logs, let me know.

@Gladry
Do you mean the no rush option ?
My AI has special builders for the no Rush Option, maybe i missconfigured the AA builders.
I will check this.

@ctrlaltdelete
AI version 92 was more or less for debugging, and i did not check the functionality with Nomads.
I will test nomads for the next AI version and fix it.
(since i also can patch the Nomads mod it will run in every case even if the problem is inside Nomads)

Thanks for reporting !!!

@Gladry

I will check this.

Question #1: T1 AA mobile units

  • In this game no-rush was not turned on - I assume the answer is about this, in any case no-rush was not on for either question.
  • T1 AA mobile were still being built at 18 minutes in, I know as I allied with an Ai-Uveso player and reclaimed (killed) 20+ T1 AAs to remove them - more were built

Question #2: Base planning

  • If a ground turret costs as much to build as 4 T1 tanks, and 4 tanks combined do 10% more damage build faster in 80% of the time - it makes sense to build the tanks instead.
  • However if someone added a mod which changed the range or DPS, build time, or build cost of the fixed turret, turret would probably be better - especially if range is significantly farther.
  • Code might check for this. AI designer might presume tanks or mobile light artillery are go-to solutions, or make comparison code

Question #3: DPS calculation

  • In your function CalculatedDPS(weapon)
  • your comment states "--Game logic rounds the timings to the nearest tick -- math.max(0.1, 1 / (weapon.RateOfFire or 1)) for unrounded values"
  • You use the calculation of actual rate of fire which I have seen mentioned elsewhere, but in no cases have I seen, when mentioned, round up or round down. I don't know for certain (you probably do) if it rounds up or rounds down.
  • Will effective rate of 1/rate = 1.66666 end up being 1.7 or 1.6. Rounding up by 0.5, as your code does, will make it 1.7 which of course is slower . 17 game ticks being more than 16 ticks.
  • Do you or others know where the FAF lua code that actually decides? I can see if the game code puts the 1/rate value into a variable, and every tick subtracts 0.10 from the value until it is <= 0, that would effectively be rounding up.

@ctrlaltdelete
please update Nomads, a patch for the error was already released in Nomads 6 days ago:
https://github.com/FAForever/nomads/pull/626

@Gladry
T1 AA mobile units:
I will reduce the amount of mobile AA in the next update.

Base planning:
My AI is meant to be played with unit mods like Total Mayhem. Thats why i have builder for pointdefenses.
Sadly you can't determine the cost of a unit before you build it.
The AI will assign a buildtask to an engineer and only the engineer will know how much the unit costs.

DPS calculation:
The game does not have any DPS calculation in LUA, it's all calculated hidden inside the c-engine.
we only try to mimic the c-eninge with LUA functions. (it is not always accurate)

@Uveso

if bp.Economy then
      if bp.Economy.BuildCostEnergy and bp.Economy.BuildCostMass 
...
end

if bp.Economy.BuildTime then
       bp.Economy.BuildTime = 
end

@Gladry

I am sorry i don't know what you want to tell me with this code snippet

Its not a part of the code we talked about, enhancements don't have a Economy sub table.

Also you don't need to ask for if bp.Economy then when you need to know if bp.Economy.BuildCostEnergy exists.
Just call directly if bp.Economy.BuildCostEnergy. it will return false if bp.Economy is missing.

@Uveso
I appreciate the response. I thought Nomads was always up to date through the patching mechanism? I am running the most recent version of FAF and it still produces the same result. Is there a way to check to make sure I am running the most recent version of nomads?

Thanks!

@ctrlaltdelete :

Good question; i always use the develop version of nomads downloaded from Git-Hub:
https://github.com/FAForever/nomads

I thought it is the same version that you can play through the FAF client.
Its both printing version 98 to the log, but the client version has still this error.

@Uveso
Hi! Encountered the same problem as ctrlaltdelete, and as I am not that techsavy, wanted to ask how should I update nomads to fix this problem?
P.S. Really like your AI, it wrecked me and my friends good, was fun expirience! Thank you for providing that!

In case you missed it on discord @Uveso

Seraphim Experimental Bomber likes to gift itself as a mass donation. It does this via a ctrl+k. It does this before dropping any bombs. I have seen this multiple times.

@plasia

Yes this bomber was driven by a suicide platoon. it was meant to just destoy itself.

This was the corresponding platoon former:
https://github.com/Uveso/AI-Uveso/blob/master/lua/AI/AIBuilders/Mobile Experimental-Air.lua#L431

Its driven by this function (AirSuicideAI):
https://github.com/Uveso/AI-Uveso/blob/master/hook/lua/platoon.lua#L2518

The suicide platoon was searching for Economic buildings.
That's why he destroyed the first Tech3 energy building closest to the AI's base.

Maybe a bad decision to do it with a suicide attack, but not a bug 🙂

I'm not trying to be rude, but follow along here:

If my teammate got up an experimental and just suicided it into something like an energy building I would be.... most upset.

It's simply a mass donation. "Oh no! not my T3 reactor, that will inconvenience me for a whole minute!" Then I profit from all that mass dropped on my front door.

Suiciding into energy... is just silly. Suiciding into something that matters, like a SMD... that makes sense.

Hey Plasia,

i am a german, and i like direct and honest answers!

You are absolutly right, its a total waste of mass and fight power.

And its already fixed!
The new target priorities for suicide platoons are:

                categories.STRUCTURE * categories.EXPERIMENTAL * categories.ECONOMIC,
                categories.STRUCTURE * categories.EXPERIMENTAL * categories.SHIELD,
                categories.STRUCTURE * categories.EXPERIMENTAL * categories.ARTILLERY,
                categories.STRUCTURE * categories.TECH3 * categories.ARTILLERY,
                categories.STRUCTURE * categories.TECH3 * categories.NUKE,

Comming soon:

Advanced ACU attack function
https://youtu.be/LvLNFyNk3kg (5 minutes)

Amost 90% of the function is finished.
I guess i will be able to make an mod update in the next 14 days.

The AI is not doing anything on some maps ex. Twin Rivers, can we get list of maps that AI should be working on?

Analyze, Adapt, Overcome...

@HintHunter

My AI is working on almost every map.
It has a build in AI waipoint generator so you also can play maps without any AI markers.

I tested Twin Rivers right now, and its working like expected.

Can you post a full game.log ?

While I expect the AI has been designed for more conventional ladder 1v1 matches rather than the 1v1 map I chose, I've still noted various issues/flaws with what the AI did which I think would be applicable more generally. This was using the 1 June uveso mod:

Replay ID #14646432
Uveso adaptive Vs guncom:

  • 1st Land fac location - it picks somewhere that requires the com to move (losing a couple of seconds)

  • Power order - It has a hydrocarbon right by the starting location, yet focuses on building 3 T1 power gens first. It'd be more efficient to have the com assist the hydrocarbon once the first engi is done (e.g. have the com get t1 mexes while the engi is being built, then assist the hydrocarbon); on a map where the hydrocarbon is further away then I could see more merit in getting more t1 pgens first

  • Power stalling and lack of focus - the AI has a com building 1 T1 pgen, an engi building a 2nd T1 pgen, and a 2nd engi building a hydrocarbon, all while power stalling. Far better to focus on the most power efficient option (Hydro), and pause any construction while power stalling until the power generation is completed

  • Mass stalling/not claiming T1 mex - the AI mass stalled for a while (with far more spent mass then generated) all while 2 unclaimed mexes are in range of engineers. While mass stalling, more power is being started/built, and then a t1 factory; far better to focus on generating easy mass (t1 extractors), then the factory (assuming more build power is needed), and then more t1 power (assuming the planned strategy requires significantly more energy), than to try and do all at once

  • Too much power - Far more power is built than needed (12 T1 and hydro would be enough if going for a gun upgrade, but instead the power is wasted)

  • Engineers sent out dont start building at nearest t1 mexes

  • Strange order changing - The first t1 engi sent out of the main base passes 2 unclaimed mexes, then goes all the way back to base while other engis go to where it originally was; presumably some command given to that first engi, but it would've make sense to take one of the others nearer the base for the new command and use the far out engi to build t1 mex

  • Unused build power/factories - Lots of t1 land factories built, but some of these appear to sit idle.
    No need to construct more factories if the existing ones aren't going to be used. The factory also sat idle despite a big threat [guncom] being scouted

  • Feeding an enemy kills - Scouts come across guncom - instead of sending all defenceless units away from it, and building up something to try and counter it, the AI keeps sending engineers and unarmed scouts piecemeal (giving the guncom free kills)

  • Storage before T2 Mex - Engineers build mass storage between 2 t1 mex; better to first upgrade those mex to t2 before building the storage

  • Mass generation prioritisation - The mass storage is built at the same time as the T2 mex upgrade, all while mass stalling. Normally it's best to focus on 1 mass generation (i.e. the t2 mex upgrade) first, and once complete move on to the next (e.g. mass storage). The exception being if there's significant amount of mass built up that can be used (not the case here).

  • Unit mix - Preference for lots of engineers over any combat units, meaning vulnerable to just about any attack. Although lots of buildpower gives the option to try and respond quicker to threats (e.g. get quick PD up, or assist an air factory to rush bombers etc.), the AI didn't make use of the engineers and hence offered no resistance to the enemy commander.

  • Counterproductive COM micro - The AI sent its unupgraded com (with no support) to fight mine. The AI com then 'stutters' (about 6m5s in), getting about 1 shot to every 4-5 of my coms (I'd expect 1 shot for every 2 of mine given mine had a speed upgrade) - it keeps rotating as if it's thinking about doing something else before switching to attacking my com. In observer mode it looks like this might be due to move commands sent to the com - maybe they're being sent/changed too often?

  • Energy storage for combat - In the situation where you have lots of surplus power and build power, minimal ground units, but your com is about to get into battle, then getting 1 energy storage as a top priority might help sway the battle in your favour.
    In this scenario it wouldn't have been enough, but would still have been of a bit of use given the excess T1 pgens that had been built

  • Response to attack - similarly to the unit mix point above, despite scouting an enemy guncom advancing on the main base, no units or pd were built in response to this threat (lots of engineers, land facs and an air fac were available). Instead some factories are idle, others are producing engineers, and 2 new naval yards are being built, all while mass stalling
