Dynamic Bot Count

[=VG= XOR]

Changing the number of bots relative to player count has long been discussed and is somewhat of  a long standing 'unresolved issue' as it can't be done  using configs or without server restart, and given some recent discussion on discord about map difficulty, i figured i might as well post this up as at the very least an alternate 'POSSIBILITY', which at present it is not.

 

So there's two ways to change bot count, either set ENTITY COUNT in server config or change LOGICAL COUNT by manipulating spawn times such that the mean number of bots SPAWNED at any point in time is lower or higher, Classical interpretation of 'count' signifies entity iterations, Logical interpretation that i use here signifies 'INTERACTIVE entity iterations', additionally (re)spawn time based entity count is the most computationally efficient way of dynamically adjusting such count without fucking up server performance, as more bots generally tend to tax a server's performance more, especially in such an old engine.

 

TLDR; It's a fairly trivial script that separates respawn times of bots & players, dynamically not only on round start but through a round as well, as players JOIN & LEAVE. 

It occurs to me that most people don't download attachments & since one needs to login to download attachments anyway, I'll just embed it below, as it's fairly trivial.

SEE CHEATSHEET IN EMBED BELOW TO SEE HOW SPAWN TIME CHANGES RELATIVE TO PLAYER COUNT, it was automatically generated so it should be a fairly accurate representation

Whiskey & Skit are gonna be too OP for the Bot if this got implemented, they finished Muttrah on their lonesome, they don't need this

[=VG= Skitalez]

Bots are bots. These are not live players. And despite the preponderance in the number (when, say, 5-10 people play on the server) and the complexity, they can always be deceived and outplayed.

This one's more of a hail mary... Just putting it out there for posterity 

[=VG= SemlerPDX]

That's some impressive scritping there, X0R!  Can I assume you've tested this already? Or is that something that would require a dedicated server and a live environment?

@=VG= Melon Muncher @=VG= Fastjack Thoughts? Notes? Feedback?  Can we implement this, or would there be compromises to doing so that would make it undesirable?

If this gets to the live testing phase here, it could be done on our Event Server since it remains offline most of the time, so long as we can set up a proper test environment (maybe dumbed down the key numbers to call a full server "10 people" and low pop "2 people", then scale it up to proper numbers after testing?

This is all assuming that this system does not require a server restart, and that the next map loaded bot count is based on currently connected players.

Yes, we are all about running a stable ship, and it was a year or more before we implemented the VG Maplist Randomizer for 'reasons', but all it takes is time to evaluate all reasons and outcomes, and then take a chance (or not).  We can always roll back or undo any changes if they don't pan out over time.

Happy to have an open discussion about this finally, when 'dynamic bot count' proposals get put on the back burner, it is so they can be brought to the front again before too long, and this is not the first time this has come up.  It deserves proper attention and deliberation for implementation, or good reasons not to.

That's outstanding work from him, Semler.

I dont know if we need this for our server(s) because some maps can be handled with 10 players. Doesn`t matter how many bots are on the other side. 

Than we have maps where 40 players aren't enough. The main problems i see are the maps with their asset layout. Khami lrg is horrible. Lashkar Infantry is a meatgrinder (i can and will not understand why we have no logitruck on it). 

But the biggest problem is :

Why we have fucking botspawnpoints inside of controlpoint areas? Or why we have active spawnpoints in a flagcap radius that is linked by another flag? To name one, Kashan with his amazing respawntime of the Milan. Those spawnpoint placements only provoking things like spawnpoint camping or causing missing boots on other important places when the server population is low.

What Coop really need is : DYNAMIC GAMEPLAY

A pythonscript that choose randomly some objectspawners and let spawn their shit. Like the ammocaches in Insurgency.

I want more dynamic gameplay and not the static gameplay we currently have in coop.

I will not have anymore what we have on muttrah like : CAS spawning - flying to castle - destroying Milan and AA - 5 minutes later the same again.

 

Here an excample what i want:

I place 50 mortars, 50 bipods and 50 AA-AT static defense in the GPO but the randomcode will only pick 4 mortars, 10 bipods and 2 Static AA's in a random manner. After one of this asset got destroyed another mortar/bipod/static AA-AT will spawn 5-10 minutes later on a different objectspawner, so not on the same position again.

No one at roundstart knows where the mortars/bipod/static AA-AT's will spawn, so CAS has to be carefully, vehicles have to play carefully and the troops also has to Move carefully. No Round will be the same because the shit that will screw up the humans not spawn anymore on the same places.

Not that i can think off, that's why i posted it here, to create discourse if nothing else.

Not only does it not require a server restart, it changes through a round,so if a round starts off with 35people and shrinks to 20people, logical bot count changes accordingly as it's constantly recalculated for every bot killed, there should be no performance penalty.

Absolutely true, however on the flipside, with an appropriate (per testing) difficulty multiplier applied, it makes it more challenging for a more full server, as normally whether or not there's a full server or not, bot respawn time is same as player respawn time, about 60sec by default which  on a full server or even half full, imho is too much.... So one might say it makes maps easier or no easier(depending on difficulty multiplier) for few, inexperienced players and makes maps harder for lots of experienced or inexperienced players alike.

I thought about having it check game tracker to check player's played hours to scale for player experience, but figured that wouldn't go down as well....

My solution for that was making every bot a contextual spawn point(contingent on vehicle type, cappable cp in range) and making every bot killed a probabilistic contextual respawn trigger(ex. every bot cas kills gets a 60% probability of respawning every shilka on map instead of current fixed respawn time AND 40% probability of cloning spawned shilka on killed bot pos instead of mapper designated pos after a delay), I'll port it at some point, It's part of a much larger script so, it's finicky to clean up.

Started porting but got stuck writing a function to validate position as being in navmesh to prevent bots dying, so i can also use player positions too as that's a more random position seed, and a  2dTo3DPos function to resolve 2d coords to 3d from height map, i'll sort that out too when motivation strikes.

I implemented this at your request, but found a bug that causes python crash after the first dozen selections(which simply changes the minMax (re)spawn time  of random spawners & despawns all on round start), been looking for a fix and what causes that for a while.... still at it, when once again motivation strikes.

Wait, wait, wait .... what?

A spawnlogic that is based on situation on the battlefield and not based on spawn/respawn timers and without fixed positions (objectspawner positions).

Yeah i think that would improve much. Some things can also be handled by mapstrategies but PR's temperature values are lightyears away from that.

I could life with having fixed objectspawners on the map because you can place many of them that make memorizing hard but your idea is great.

 

Would it be possible to spawn a bot with a kit that isn't in the selection menu?

Excample:

Multiple bots got killed by CAS. Now, a trigger let spawn a bot with a manpad.

or :

Multiple bots got killed by tank. Trigger let spawn a bot with a HATkit.

Come on please say YES its possible.

It's not only possible, it's fairly trivial. The only caveat being, though

host.rcon_invoke("gamelogic.setkit ****")

sets ANY KIT initialized for a given faction in real-time, it changes OVERALL  kit composition of bots on successive re-spawns & not immediately, instead of only INDIVIDUAL bot kits. Which might actually be more ideal, if it's constantly being set to a different kit relative to dominant threat at any given point in time, though not as targeted, it makes it so that if armor dominates the battlefield, a majority of bots that re-spawn do so with AT, though i'm sure you already know of the issue with bots using MANPADS.

There is of course also a targeted solution, a simple (re)spawn handler can be used to shuffle spawns, such that any bot that spawns with AT kit spawns at  pos of any other bot killed by ARMOR(with random delay) for instance, or just at closest spawn point to killer(player).
 

In-fact I recall writing a dumb little function for this, I called it DIE_VERSION, it was supposed to signify that the player was going to die in the next encounter with a bot the player killed.... I digress though, I'll probably pack it along with some other stuff I've written over the years and make a post or something at some point, I've thought about doing so, just got lazy.

Not really, what issue do you mean? Hipfiring is one problem i'm aware about or the old look up wrapper error but that is fixed.

It's also possible to bypass problems - generally done when you think out of the box. 

About the motivation thingy -

i know what you mean and can understand that. In my case i lose focus or interrest because i'm working alone the most time on coop insurgency and there are so many things todo to improve coop but unbearable for one person. To much work.

Well there you go, never knew that got fixed, was out of the loop for a while, so I guess manpads shouldn't be a problem then.

Let's assume you wouldn't, surely you want more bots though, eh? So that's the flip side, depending on how you configure the difficulty multiplier, you can avoid fewer bots while having more for higher player numbers, it's entirely left to configs, like all good things in life

It can be, but not on any officially sanctioned server, at least not anytime soon. You'll most likely come across it in events, should anyone choose to use such functionality.  But as for is it possible, absolutely, I've done it & so have others.

[=VG= XOR]

Just to crystalize a particularly important point I failed to articulate, such a system for the most part  removes server population as a variable in map selection, which meaningfully translates to, ANY MAP CAN BE PLAYED BY ANY NUMBER OF PLAYERS, and thus repetition is reduced and variety of viable maps increased exponentially. Just wanted to put that out there, as I'd forgotten to do so.

[=VG= SemlerPDX]

Ya know, some good points where brought up here that made me come to some odd conclusions and I don't even know if this line of thinking is productive, or these things possible...

Say it's low population - the system knows that it shouldn't pelt them with too many bots, so it does what you designed it to do... how about the scenario where no new players join, but this same small team starts killing it - like not just taking points, but steamrolling them.  Can the system have functions to differentiate such swift advancement from what we could term 'standard flow' advancement which typically only sees one to two points capped in a sort period (but not 3, or 4)?

What I'm thinking is that the system could figure out if it's gone 'too' easy on a low pop scenario and adjust accordingly... maybe the 7 people that are on have 4000+ hours each in the game, right?  But it needs to be able to 'be easy' for 6 noobs and a single trained regular player, too, right?

Just thoughts - not trying to make extra work, or anything like that... merely posing the idea or question of possibility (dynamics within dynamics).

  

The more I read about this, the more I'm feeling we should make it happen - even if it means some minor requests if feasible, or fine tuning based on feedback from our PR Server Managers here (if you don't mind, of course).  I think the future of PR COOP might very well need this, since the population swing is more of an issue the more PR ages.

How about a 'retreat' bleed?  BLUFOR has capped all zones, and admins would otherwise need to 'run next' or kill bots streaming out of main for 30+ minutes, so instead, the system notices and issues a 'retreat' which causes OPFOR ticket bleed to increase dramatically and swiftly?  When no admins present, this would allow map to progress swiftly to next map without someone seeking out an Admin just so players don't need to 'run out the clock' as it were.

I already wrote a script that on every CP capped checks if all capable CP's are owned by team 2 && if so sets bot team tickets to 0 after 15 sec triggering end of round by team 2 victory. I'll post it if you wish, should certainly make no-ticket bleed a thing of the past, with rare exceptions like cappable CP in dod for instance. *also attached below* @=VG= SemlerPDX

What I'm thinking is that the system could figure out if it's gone 'too' easy on a low pop scenario and adjust accordingly... maybe the 7 people that are on have 4000+ hours each in the game, right?  But it needs to be able to 'be easy' for 6 noobs and a single trained regular player, too, right?

Should be simple enough, it's a simple matter of adding a factorial that uses KD to evaluate player skill relative to time elapsed, higher KD in a given unit of time signifying higher skilled player. An even simple way to balance this would be to increase the difficulty by .1% for every bot killed and reduce it by 1% for every player killed which results in a more emergent & fluid difficulty balance.

 

Here's an updated script, also attached, that uses a sigmoid function to dynamically adjust difficultyMultiplier based on KD ratio of players for every bot killed, such that the more players there are with high KD ratios the lower the difficultyMultiplier, which translates to higher bot count,  with difficultyMultiplier never exceeding config defind value, such that it' can get exponentially more difficult relative to more experienced players but it never gets easier beyond value defined in config.

tldr;  player KD ratios continually modify difficultyMultiplier with an upper limit for every bot killed and player count continually forces recalculation of bot respawn times relative to player count for every bot killed so as to modify the mean number of bots active in a given unit of time, i.e logical bot count. @=VG= SemlerPDX
