#

for legal reasons i am obligated to state this is a joke

keen ruin Jan 18, 2025, 5:29 AM

#

oh

#

oopsie

crimson jolt Jan 18, 2025, 5:29 AM

#

just very low hanging friut

keen ruin Jan 18, 2025, 5:29 AM

#

someday that will be real

ashen harbor Jan 18, 2025, 5:29 AM

#

It doesn't happen without v2 no

keen ruin Jan 18, 2025, 5:30 AM

#

it definitely does

ashen harbor Jan 18, 2025, 5:30 AM

#

But it seems like you guys have figured out a lot while I was afk

keen ruin Jan 18, 2025, 5:30 AM

#

the ShootGun part

ashen harbor Jan 18, 2025, 5:30 AM

#

Oh really?

#

I wonder why it only logged with v2 odd

keen ruin Jan 18, 2025, 5:30 AM

#

it's because of BetterShotgun

ashen harbor Jan 18, 2025, 5:30 AM

#

XD

#

I see

keen ruin Jan 18, 2025, 5:30 AM

#

did you check your logs before that? you don't have the console enabled

ashen harbor Jan 18, 2025, 5:30 AM

#

So @candid nimbus needs to release a patch it seems

keen ruin Jan 18, 2025, 5:30 AM

#

erm

#

only a very minor one

#

I was gonna let Xu let them know what they need

ashen harbor Jan 18, 2025, 5:31 AM

#

keen ruin did you check your logs before that? you don't have the console enabled

Yeah I've always checked my logs and never seen that but however

#

I wonder if it's one of those things that used to not log for me as host but logged for clients

#

Since some errors do that

keen ruin Jan 18, 2025, 5:31 AM

#

the most important question I have is how sure you are that this softlock is a regression in PathfindingLagFix

#

because I haven't been able to reproduce it and so I have no idea what is causing it

ashen harbor Jan 18, 2025, 5:32 AM

#

Pretty certain, It seems to be exclusive to multiplayer

keen ruin Jan 18, 2025, 5:32 AM

#

the only thing I can think is that the Unity jobs system is screwing with object lifetimes and making RPCs run after the network disconnects

green gust Jan 18, 2025, 5:32 AM

#

everyone runs ShootGun afaik so it would show on everyone's end

ashen harbor Jan 18, 2025, 5:32 AM

#

@oak timber Do you still have your log from today?

#

Or maybe @kind elk might, he played with

ashen harbor Jan 18, 2025, 5:33 AM

#

green gust everyone runs ShootGun afaik so it would show on everyone's end

Huh I wonder how I never saw it sooner lmao

keen ruin Jan 18, 2025, 5:33 AM

#

green gust everyone runs ShootGun afaik so it would show on everyone's end

not only that but people that don't own the shotgun would have that error regardless of whether they are running BetterShotgun

#

the array isn't populated unless it is owned

ashen harbor Jan 18, 2025, 5:33 AM

#

I'm wondering if clients got an error when I tried to close the lobbies out

keen ruin Jan 18, 2025, 5:33 AM

#

hmm

#

I wouldn't think that would have any bearing on whether you close the lobby as host but maybe someone else could confirm that

green gust Jan 18, 2025, 5:34 AM

#

keen ruin the array isn't populated unless it is owned

hmm i'll double check that but that would make sense

ashen harbor Jan 18, 2025, 5:34 AM

#

Cus I didn't see anything besides Dissonance being the first error

keen ruin Jan 18, 2025, 5:34 AM

#

dissonance wasn't the first error doe

#

at least not in some cases

#

everything points to RPCs being sent while the network is disconnected

#

it's almost like the disconnect event is firing twice

#

no clue why

#

but I really find it hard to believe this is PathfindingLagFix's fault

ashen harbor Jan 18, 2025, 5:35 AM

#

It could be a run order thing

keen ruin Jan 18, 2025, 5:36 AM

#

if it isn't getting completely frozen I don't know what would cause this

#

I don't screw with lifetimes intentionally

ashen harbor Jan 18, 2025, 5:36 AM

#

since I don't repro it with stable I just dunno what

keen ruin Jan 18, 2025, 5:36 AM

#

I don't even have any hard refs to enemies to keep their managed objects alive

ashen harbor Jan 18, 2025, 5:36 AM

#

Maybe I could send you my pack and a profile might reveal it?

keen ruin Jan 18, 2025, 5:36 AM

#

I've tried several times to repro with your pack

#

even with the one from today

ashen harbor Jan 18, 2025, 5:37 AM

#

Yeah that is also what makes it so strange

#

🤔 I wanna know what is misbehaving

#

lol

keen ruin Jan 18, 2025, 5:37 AM

#

you're sure nothing else updated that might be relevant here?

#

also idk if you said, but did you ever downgrade PathfindingLagFix since this started happening to confirm that it definitely doesn't happen unless v2 is present?

#

would be good to see in a long session with several attempts

green gust Jan 18, 2025, 5:38 AM

#

postfix's run even if a function returns early right @keen ruin

keen ruin Jan 18, 2025, 5:38 AM

#

for harmony yes, I believe so

#

when MonoMod is involved, no clue

green gust Jan 18, 2025, 5:39 AM

#

cuz ii've never seen the error before, but you're right that it returns early

keen ruin Jan 18, 2025, 5:39 AM

#

I can never remember which detour is first

ashen harbor Jan 18, 2025, 5:39 AM

#

We swapped to V1 yesterday after we couldn't land on Black Mesa and played out the rest of the session and I could close it out just fine

keen ruin Jan 18, 2025, 5:39 AM

#

well if you're host you own the shotguns to start

#

and nutcrackers never change ownership either

keen ruin Jan 18, 2025, 5:39 AM

#

ashen harbor We swapped to V1 yesterday after we couldn't land on Black Mesa and played out t...

how many times did you do so?

ashen harbor Jan 18, 2025, 5:40 AM

#

Just the 1 time

#

but I tried to close it out twice with v2 and couldn't

green gust Jan 18, 2025, 5:40 AM

#

keen ruin well if you're host you own the shotguns to start

im almost never host when playing DogeKEK ,but yeah i havent looked at logs specifically to test it

keen ruin Jan 18, 2025, 5:40 AM

#

if I'm not getting repro on your pack even in LAN I suspect that that isn't enough

green gust Jan 18, 2025, 5:40 AM

#

ig ill add a null check

ashen harbor Jan 18, 2025, 5:40 AM

#

once when we ran into the bug with DemonMae's Interior, 2nd time when Black Mesa soft locked

#

I do suspect if V2 can't be responsible inherently

#

it's some sort of run order thing

#

something trying to sent a network rpc to a client and dying

#

just dunno why

keen ruin Jan 18, 2025, 5:41 AM

#

idk what run order would be relevant here

ashen harbor Jan 18, 2025, 5:41 AM

#

I don't either

#

I wish when it gives that network error it would be more descriptive

#

other than just saying a rpc failed

keen ruin Jan 18, 2025, 5:41 AM

#

in the logs you sent I don't even see anything from PathfindingLagFix at all, and only an error could really cause this

#

none of my patches even do anything with anything other than enemies

ashen harbor Jan 18, 2025, 5:42 AM

#

Well the most recent addition that might be responsible could be Piggy's Variety Mod and I already mentioned I'm gonna test removing that for tomorrow

#

since I've also been getting stuck on "You are fired" as well if we end a run

keen ruin Jan 18, 2025, 5:43 AM

#

ah yeah I should try doing that

#

just for giggles

#

also is it a known issue that the stream overlay mod softlocks clients (in lan only perhaps)?

#

I guess the issue is probably it binding the same local port twice without checking or something

ashen harbor Jan 18, 2025, 5:49 AM

#

It is

#

@vagrant gazelle weren't you gonna fix this btw?

#

lol

ashen harbor Jan 18, 2025, 5:49 AM

#

keen ruin I guess the issue is probably it binding the same local port twice without check...

Might very well be this

vagrant gazelle Jan 18, 2025, 5:49 AM

#

ashen harbor <@675902479245770810> weren't you gonna fix this btw?

What

ashen harbor Jan 18, 2025, 5:49 AM

#

vagrant gazelle What

Stream Overlays breaking lan

#

XD

#

I remember you said you were gonna fix it a while ago

#

peepoGiggles

vagrant gazelle Jan 18, 2025, 5:49 AM

#

I don't know how to

#

I already tried to fix it in the past

ashen harbor Jan 18, 2025, 5:50 AM

#

Well you got some mod devs here that may be able to help you

#

Zaggy and Xu might know a bit more

#

:3

keen ruin Jan 18, 2025, 5:52 AM

#

I mean is it checking that it was able to bind the socket before trying to use it everywhere? my first thought is, just shut it down if it can't bind it

#

https://github.com/ZehsTeam/Lethal-Company-StreamOverlays/blob/main/StreamOverlays/Server/WebServer.cs#L60

if (!_webSocketServer.IsListening)
{
    _webSocketServer = null;
    return;
}

would this work?

ashen harbor Jan 18, 2025, 5:57 AM

#

keen ruin https://github.com/ZehsTeam/Lethal-Company-StreamOverlays/blob/main/StreamOverla...

@vagrant gazelle

keen ruin Jan 18, 2025, 5:58 AM

#

that's assuming Start() is synchronously binding the port, but idk really

#

another option is to check _webSocketServer.IsListening before broadcasting I suppose, since the error I'm seeing is:

Failed to assign new player with client id #4: System.InvalidOperationException: The current state of the manager is not Start.

#

(Lunx I will allow Zehs to reply whenever they have time lol)

ashen harbor Jan 18, 2025, 6:01 AM

#

Ye I think they went afk, they were active in a stream I'm watching and they poofed from there too so hopefully they see it later lol

keen ruin Jan 18, 2025, 6:02 AM

#

it's not a huge deal, it's just one more thing to adjust when I need to do stuff in your pack

ashen harbor Jan 18, 2025, 6:02 AM

#

Ye

keen ruin Jan 18, 2025, 6:11 AM

#

good lordy what is this scp999 thing doing to my fps

#

ashen harbor Jan 18, 2025, 6:11 AM

#

keen ruin

Oh no is he still doing some expensive stuff?

#

;c

keen ruin Jan 18, 2025, 6:12 AM

#

it would appear so

ashen harbor Jan 18, 2025, 6:13 AM

#

Well @gentle charm Would be the dev of SCP 999, hopefully it's something that is easy to fix

keen ruin Jan 18, 2025, 6:16 AM

#

might be the TargetClosestEnemy method, not sure

#

I would assume while I'm outside the enemy would be roaming

ashen harbor Jan 18, 2025, 6:16 AM

#

It's possible yeah

keen ruin Jan 18, 2025, 6:17 AM

#

I'm beginning to be convinced that Unity made it too easy to test paths

#

one very easy optimization though:

- if (!PathIsIntersectedByLineOfSight(enemy.transform.position, calculatePathDistance: false, avoidLineOfSight: false) && (!requireLineOfSight || CheckLineOfSightForPosition(enemy.transform.position, viewWidth, 40)))
+ if ((!requireLineOfSight || CheckLineOfSightForPosition(enemy.transform.position, viewWidth, 40)) && !PathIsIntersectedByLineOfSight(enemy.transform.position, calculatePathDistance: false, avoidLineOfSight: false))

#

although I guess it's probably not using the LOS check

#

no wait it is

#

teehee

#

also

- if ((TargetClosestPlayer(1.5f, true) && followPlayer) || (TargetClosestEnemy(1.5f, true) && followEnemy))
+ if ((followPlayer && TargetClosestPlayer(1.5f, true)) || (followEnemy && TargetClosestEnemy(1.5f, true)))

please check the easy stuff first

#

this async API is looking all the more important, but I might be too lazy to make it usable enough for everyone to adopt it without a lot of coaching

#

I'd probably have to set up a bunch of helpers and I'm not sure what that would look like to do it in a generalized way

ashen harbor Jan 18, 2025, 6:24 AM

#

Yeah at least these changes should be useful for the SCP 999 mod, since it has a github you might be able to push a pr too

keen ruin Jan 18, 2025, 6:25 AM

#

that requires me to set up a local copy 😅 if I were to go to that effort I would much rather just go the full way and make it async

ashen harbor Jan 18, 2025, 6:25 AM

green gust Jan 18, 2025, 6:27 AM

#

also off the top of ur head, does the playerSteamId field get filled in with anything if you're on lan?

keen ruin Jan 18, 2025, 6:27 AM

if the project is set up nicely it doesn't really take too long

ashen harbor Jan 18, 2025, 6:27 AM

at least to do the PR, testing is the time consuming part

keen ruin Jan 18, 2025, 6:28 AM

#

green gust also off the top of ur head, does the playerSteamId field get filled in with any...

I doubt it

#

I don't really know

ashen harbor Jan 18, 2025, 6:28 AM

#

green gust also off the top of ur head, does the playerSteamId field get filled in with any...

I don't think so, doesn't it just label you as Player#0 and Player#1, etc in lan?

green gust Jan 18, 2025, 6:28 AM

#

yeah but i doubt theres any relevance there to that

keen ruin Jan 18, 2025, 6:29 AM

#

it doesn't connect the Steam API when you do LAN so it can't get a valid ID

#

all it can do is come up with a bogus one if anything

ashen harbor Jan 18, 2025, 6:29 AM

#

Yeah Lan is all offline stuff

green gust Jan 18, 2025, 6:29 AM

#

yeah i wondered whether it's a bogus number, or null since its ulong or 0

#

yes lunxara im aware

ashen harbor Jan 18, 2025, 6:30 AM

green gust yes lunxara im aware

Oh I figured

I probably didn't need to tack it on tbh peepoGiggles

keen ruin Jan 18, 2025, 6:32 AM

when you had the softlock after being fired, was it just stuck on the fired screen and otherwise running normally?

keen ruin Jan 18, 2025, 6:34 AM

I would love to know if you can go a 3 or more reloads without getting softlocked in normal play with stable PathfindingLagFix

keen ruin Jan 18, 2025, 6:35 AM

#

ashen harbor I remember a client saying their game crashed when they tried to leave after it ...

hmm a dump from them would be helpful then

#

probably not likely to be the NavMeshQuery crash but can't hurt for me to check the stack trace

There was an error from BetterShotgun that was discovered that needs fixed basically

#

This one I believe

#

the Shootgun Error

candid nimbus Jan 18, 2025, 10:44 AM

#

ashen harbor

I am not the person who coded the bettershotgun, however I think the problem occurs because the bettershotgun replaces the original shotgun code? That's the only thing that comes to mind since it's the first time I've seen this kind of error

ashen harbor Jan 18, 2025, 10:55 AM

#

Yeah I think @green gust is supposed to inform you of what needs changed from what I understood

candid nimbus Jan 18, 2025, 11:14 AM

#

so I did some testing in the meantime and it seems to only happen when CodeRebirth is installed?

tardy pivot Jan 18, 2025, 11:15 AM

#

🤔 @ashen harbor either you swapped the sqlite file or you never downgraded PathfindingLagFix 🤔

#

from the logs issue only happend in the execution nr° 12. and only once

green gust Jan 18, 2025, 1:24 PM

#

candid nimbus so I did some testing in the meantime and it seems to only happen when CodeRebir...

iirc only issue i really had was that your IHittable code assumes that PlayerControllerB is in IHittable non-nullable, also you never populate the RayCastHit[] enemyColliders which some mods might rely on, if you could populate that with your hits that you get, even if only for the owner (which the game does), that'd be great

#

https://github.com/Entity378/BetterShotgun/blob/main/ShotgunPatch.cs#L165-L173 would probably populate it somewhere here with your hits, if im understanding whats happening right, lol

candid nimbus Jan 18, 2025, 1:32 PM

#

green gust https://github.com/Entity378/BetterShotgun/blob/main/ShotgunPatch.cs#L165-L173 w...

I can try, the code is the same as the original hexibettershotgun and I've never touched it. The mod simply needed to be recompiled due to new versions of the game and since the original owner couldn't compile the mod I did it myself

#

basically i'm saying that i don't know how the mod works either

green gust Jan 18, 2025, 1:33 PM

#

okay glad to know we both dont, the second issue should be simple since it's just a field in the shotgun code, i assume it'd be easy to just populate that with the hits that are made by that mod

#

for the first one then um we ball

#

oh actually this is probably for the first issue

#

nvm holder isnt even used lol

#

you could probably just get rid of that line DogeKEK

#

it might error if the shotgun is fired without a player holding it?

candid nimbus Jan 18, 2025, 1:35 PM

#

since it is not used I don't think it gives an error. I remove it anyway to be safe

#

wait

#

enemyColliders is private? because in that case I don't know how to access it.

#

The more I code for this game the more ignorant I feel (even after 1 year of doing it)

#

I mean, the only thing I can think of is using Reflection to access enemyColliders but other than that I have no idea

green gust Jan 18, 2025, 2:03 PM

#

candid nimbus I mean, the only thing I can think of is using Reflection to access `enemyCollid...

My bad, uh you could publicise the assembly

That's usually the best way to access private or internal fields

so, i tried it and now it seems to work (no more errors)

keen ruin Jan 18, 2025, 2:32 PM

#

hmm I think it's a bit silly to waste time on filling the array if you're doing things the right way and calling IHittable.Hit unconditionally

#

the only reason that Xu has to use that array is because zeekerss doesn't use IHittable properly there yet

candid nimbus Jan 18, 2025, 2:39 PM

#

maybe it's a waste of time but I still prefer to fill it ~~"correctly"~~.

tardy pivot Jan 18, 2025, 2:40 PM

#

i mean the "correct" way would be to do it like vanilla does and use RacastNonAlloc passing the original array 😅

keen ruin Jan 18, 2025, 2:41 PM

just as long as you're not making it allocate every time I guess

tardy pivot Jan 18, 2025, 2:42 PM

yeah, the array is just used as a buffer to put the colliders into

unsure if it clears the array to null before it fills the buffer with the hits though, and the count of hits being a return value almost guarantees it to end up in a local variable (not at my PC rn to check it it is in vanilla), so using it feels a little sus to me anyway

#

@keen ruin no crashes, aint got no logs for any crash

#

so all is good i guess

keen ruin Jan 18, 2025, 3:13 PM

oh weird

#

you said it crashed though right?

kind elk Jan 18, 2025, 3:14 PM

i didnt get any errors or unity popup my game just closed on join

couldve accidentally close my console

keen ruin Jan 18, 2025, 3:14 PM

anyway yeah without a log or dump I gotta assume it was something else

ah

we shall never know

probably was nothing

Foreshadowing is a narrative device in which a storyteller gives an advance hint of what is to come later in the story.

keen ruin Jan 18, 2025, 3:58 PM

I don't like the sound of that kind of foreshadowing

keen ruin Jan 18, 2025, 6:11 PM

out of curiosity, has anyone else been using Beta v2.0.3 and encountered issues with closing lobbies?

So old SQLite got deleted

ashen harbor Jan 18, 2025, 10:31 PM

#

@keen ruin just wanted to let you know I've been able to close out lobbies just fine today after pulling Piggy's Variety Mod and updating HexiBetterShotgunFixed

#

So I would guess it was cus of Piggy's

keen ruin Jan 18, 2025, 10:31 PM

#

ah that's good to hear, how many times have you closed out thus far?

#

I tested your profile code from yesterday's stream with Matty and wasn't able to reproduce there, so I'm wondering if it could just be very intermittent, but it's also very plausible that it could just be something breaking in some update

keen ruin Jan 19, 2025, 12:46 AM

#

Just pushed a new version 2.0.4 which

Removes the crash warning from the readme, since things have seemed stable since my fix
Adds a patch to reduce the impact of pathfinding used to check if an enemy can target each player in the lobby, which would manifest as a small stutter in large lobbies and is used by a lot of enemies in the game:

#

@green gust I shall prioritize making an API for you to use to make Jimothy stable next, fear not

green gust Jan 19, 2025, 12:53 AM

#

Yipp

keen ruin Jan 19, 2025, 12:59 AM

#

to start with I can probably just give you the synchronization methods that I use in PathfindingLagFix, should be very easy to plug in then

#

not sure if it's better to do that or just yoink the job code out of CodeRebirth for the API Hmm

#

is that code on your GitHub and up to date?

green gust Jan 19, 2025, 1:05 AM

Yes

Does this mod work with Lockers?

that's an oddly specific question that I don't necessarily know the answer to, but I don't know of any mods that would have issues with it

lyric hedge Jan 19, 2025, 3:06 AM

#

keen ruin that's an oddly specific question that I don't necessarily know the answer to, b...

I should clarify: does the Locker cause any stuttering, and if so, will the mod fix said stuttering?

keen ruin Jan 19, 2025, 3:06 AM

#

oh

#

no clue

#

I've never played with locker tbh

#

I doubt it has any stutters that even the beta would solve entirely, unless it's doing something very bad

#

but whether there are stutters is up to your testing

lyric hedge Jan 19, 2025, 3:08 AM

#

I didn’t notice anything. Then again, my game slows down a bit when lots of monsters are spawned, so it’s hard to know whether it’s somewhat caused by the Locker.

keen ruin Jan 19, 2025, 3:09 AM

#

yeah

#

if you didn't have the beta when said slowing happened, then hopefully it will be able to help with that

#

that's exactly what the beta is supposed to improve, though it is incomplete at the moment

lyric hedge Jan 19, 2025, 3:18 AM

#

Any crashes that I should know of? Like, does this mod work with vanilla Lethal Company?

keen ruin Jan 19, 2025, 3:19 AM

I only really test against vanilla

I haven't had crashes reported since the fix in 2.0.3

Pathfinding Lag Fix v2 (BETA)

green gust Jan 22, 2025, 7:30 AM

#

guys, make fun of this guy for using the wrong icon

ashen harbor Jan 22, 2025, 7:43 AM

#

@keen ruin I'm guessing I should add PathfindingLib once it becomes available? 👀

green gust Jan 22, 2025, 7:43 AM

#

lib will be a dependency of coderebirth next update

#

and probably pathfinding lag fix v2 since he moved the stuff there i assume(?)

ashen harbor Jan 22, 2025, 7:44 AM

#

Yeah I figured it was something I should add the second it becomes available

green gust Jan 22, 2025, 7:44 AM

#

doesnt do anything by itself

ashen harbor Jan 22, 2025, 7:44 AM

#

I see it being a dependency for a lot of things

keen ruin Jan 22, 2025, 7:48 AM

#

yeah it'll be a dependency of PathfindingLagFix Beta soon enough

#

and then PathfindingLagFix proper after that

#

it's only there for Xu to use it until anyone else decides to dip their toes into this

#

but it takes a little bit of what could potentially be considered boilerplate to be usable for an enemy, so we'll see how many others use it initially

#

first one that comes to mind is Lethal Intelligence, but I kind of want to make an even higher level API within PathfindingLib before I suggest anything like that

#

I would prefer that PathfindingLib takes over all the fire exit pathfinding logic that Virus has been working on there, but we'll see

#

(coincidentally that is also what I suggested Xu use it for)

green gust Jan 22, 2025, 7:57 AM

#

thats what i was already using it for smh

ashen harbor Jan 22, 2025, 7:58 AM

#

Oh good, no more lag when gals are pathing to entrances

green gust Jan 22, 2025, 7:59 AM

#

there wasnt any lag previously for gals pathing to entrance, im just accomodating smarter pathing

#

and well, more pathing

keen ruin Jan 22, 2025, 7:59 AM

#

green gust thats what i was already using it for smh

that's what I meant lmao you were trying to solve the fire exit pathing and I was like async would be pretty bussin here

green gust Jan 22, 2025, 7:59 AM

#

yeah true

ashen harbor Jan 22, 2025, 7:59 AM

#

green gust there wasnt any lag previously for gals pathing to entrance, im just accomodatin...

There is actually, if you go inside before they do there is some lag, likewise the same happens if you go outside and they take a bit to find their way out

#

It's only those cases though

keen ruin Jan 22, 2025, 8:00 AM

#

makes sense there could be a little perhaps, surprising to me if it was that noticeable tbh

#

Xu, weren't you choosing just one entrance teleport to check before? I forget

#

maybe you were checking all idr properly

#

I forget how often/how many paths you were calculating

green gust Jan 22, 2025, 8:05 AM

#

keen ruin Xu, weren't you choosing just one entrance teleport to check before? I forget

i never checked whether anything was pathable

#

i stored a list of exits i KNEW were pathable because the player who owns the gal already used em

keen ruin Jan 22, 2025, 8:05 AM

#

ohhh okay

green gust Jan 22, 2025, 8:06 AM

#

it would cause issues if doors were to get locked, but i never calculated any paths, except one for disabling the agent

keen ruin Jan 22, 2025, 8:06 AM

#

that must have been before I saw the code properly, I'm guessing

green gust Jan 22, 2025, 8:06 AM

#

yuh

keen ruin Jan 22, 2025, 8:06 AM

#

then yeah it probably shouldn't have been too noticeable

#

oh yeah and @ashen harbor idk if you're still thinking of adding the lib, but I would definitely recommend to wait until I make it a dep, my own patches may conflict with themselves otherwise lol

#

I haven't checked that

ashen harbor Jan 22, 2025, 8:10 AM

pushed out the update to make PathfindingLagFix Beta use PathfindingLib, there should hopefully be no behavior changes

I'm looking at patching the tulip snake now, @crimson jolt did you have a patch to replace calls to FindObjectsByType already? I'm thinking of making some patches for those calls to make them use lists without allocating but I don't want to break on other patches if there are any

#

I feel like I remember someone mentioning doing that, but I forget who

crimson jolt Jan 22, 2025, 9:57 PM

#

it wasn't me

#

i believe it was @vagrant gazelle

keen ruin Jan 22, 2025, 9:57 PM

#

ah yeah, I think you're right

crimson jolt Jan 22, 2025, 9:57 PM

#

the only place i patch tulip snakes is jetpack fixes and enemy sound fixes

keen ruin Jan 22, 2025, 9:58 PM

#

notedd makes sense

crimson jolt Jan 22, 2025, 9:58 PM

#

and i can link you both repositories if you want to peek at them to make sure you won't conflict with anything

but im willing to bet anything you touch pathfinding-wise should be fine

keen ruin Jan 22, 2025, 9:58 PM

yee that's pretty clean NODDERS

#

I would like to try to make one that's non-allocating, but it would need to be a little bit more involved obviously

#

I guess that we shouldn't really have issues with each other's patches considering that it should be a no-op if it finds no call to FindObjectsByType actually

vagrant gazelle Jan 22, 2025, 10:13 PM

#

I never released the mod nkoHehe

keen ruin Jan 22, 2025, 10:13 PM

#

ohh ok lol

#

basically mine will be very similar except using an internal Unity API to grab the array out of the list, then transpile ldlen to use get_Count instead

crimson jolt Jan 22, 2025, 10:17 PM

#

the whole enemy thing is kind of bizarre

#

zeekerss keeps a constant list of spawned enemies on RoundManager.Instance

#

which, after the course of multiple updates to the game, now catalogs all enemies on all clients (except that masked still only work for host but they are the exception)

#

but he doesn't even iterate that list here, just does a findobject for flower snakes

keen ruin Jan 22, 2025, 10:19 PM

#

yeah it would be a little uglier but faster to do that

crimson jolt Jan 22, 2025, 10:19 PM

#

iirc the only place he uses the cached enemies is for the "Nearby activity detected" prompt on the teleporter doors

keen ruin Jan 22, 2025, 10:19 PM

#

but also it's not hard to just maintain a list in OnEnable/OnDisable

#

I think it's used for more than that, but not that much iirc

crimson jolt Jan 22, 2025, 10:19 PM

#

yeah i was going to say it's even more bizarre because flower snakes have a static list called mainSnakes

keen ruin Jan 22, 2025, 10:19 PM

#

I forgor what the usecase I looked at recently was though

crimson jolt Jan 22, 2025, 10:20 PM

#

which you'd think would point to all the tulip snakes with isMainSnake = true

keen ruin Jan 22, 2025, 10:20 PM

#

crimson jolt yeah i was going to say it's even more bizarre because flower snakes have a stat...

(that isn't populated lmao)

crimson jolt Jan 22, 2025, 10:20 PM

#

except for some reason he doesn't use it at all

#

just resizes it when the first tulip snake spawns

keen ruin Jan 22, 2025, 10:20 PM

#

I was gonna use that for OpenBodyCams but I couldn't

crimson jolt Jan 22, 2025, 10:20 PM

#

i assume it's just commented out in his project somewhere

keen ruin Jan 22, 2025, 10:20 PM

#

probably

crimson jolt Jan 22, 2025, 10:20 PM

#

all the code using it

keen ruin Jan 22, 2025, 10:21 PM

#

I think there's a couple places where it should have been used iirc

crimson jolt Jan 22, 2025, 10:21 PM

#

i think this community (myself included) can be a bit too nitpicky about zeek's code sometimes

keen ruin Jan 22, 2025, 10:21 PM

#

oh for sure

crimson jolt Jan 22, 2025, 10:21 PM

#

but the like. #1 most painful thing is seeing find calls that really should not exist

#

Lol

keen ruin Jan 22, 2025, 10:21 PM

#

yeah it is a common mistake among modders to tbf

crimson jolt Jan 22, 2025, 10:21 PM

#

anytime he uses findobjectoftype<roundmanager> or some other singleton it brings a tear to my eye

#

because those can at least be fixed with 0 refactoring

keen ruin Jan 22, 2025, 10:22 PM

#

that's probably old code that has been long forgotten tbh

crimson jolt Jan 22, 2025, 10:22 PM

#

i assume so yeah

keen ruin Jan 22, 2025, 10:22 PM

#

should definitely do a find in project but oh well

crimson jolt Jan 22, 2025, 10:22 PM

#

hopefully one of these days he just does a ctrl+F on everything and makes the changes

#

yeah

#

anyways sorry i derailed a bit

#

in other news

#

always makes me happy to see pathfindinglagfix grow in power with each new development

#

hoping v2 can have a smooth release soon

#

i've been using the beta on my debug profile but i've been sticking to stable with my friends since we have to rehost enough anyway because of other issues

#

so far i've personally encountered no issues but that's probably not the best data to sample

keen ruin Jan 22, 2025, 10:52 PM

#

I think it should be safe to use in normal play, at least as far as stability goes

#

it's possible that I have introduced some regressions in enemy behavior, but that would be good to find out through normal play

#

Lunxara hasn't stopped using it since 2.0.4 (for long at least) afaik, and it hasn't caused a crash

#

if new crashes do pop up, I'm fairly confident I'll be able to fix them the same way I've fixed all the other causes, only question is how long it'll take to figure out how to reproduce the particular new cause

kind elk Jan 22, 2025, 10:54 PM

That is correct no crashes

crimson jolt Jan 22, 2025, 11:00 PM

#

keen ruin if new crashes do pop up, I'm fairly confident I'll be able to fix them the same...

just out of curiosity

#

do you foresee problems with mix&matching stable and beta across players?

#

i could maybe start using the beta on my end (i host all our games if it's relevant) to try and get some real sample data

#

but i'd feel bad telling them all to shift to beta then making them shift right back if there are problems

#

so i might not advise them to make the switch until it's live

keen ruin Jan 22, 2025, 11:03 PM

#

should be fine, each enemy only does pathfinding on one client at a time (mostly the host, you)

#

I've used beta on host and on client while others were on stable and had no issues

#

not as much when I was host though tbf

#

simply because it's been a while since I hosted

#

regardless, no reason it should have issues

ashen harbor Jan 22, 2025, 11:04 PM

#

I've been keeping it in my pack as a main stay since it got fixed yeah

#

I still dunno what Piggy's Variety Mod was doing that caused me to be unable to close lobbies

Version 2.0.6 (Beta)

Added some tulip snake patches to prevent stutters, especially just after they have dismounting a player.

Holy shit Takerst is gonna love this

He always mentioned the lag from them

#

lol

keen ruin Jan 23, 2025, 1:15 AM

#

nice lol

#

I've heard it from a few people including you, but only recently found out it was specifically happening largely only when they dismount

#

made it much easier to determine what exactly I needed to patch

#

if there are other situations in which you see bad performance from them though, lemme know

#

they do also have a serious cost just due to having two animators, which I have yet to figure out a proper solution to

ashen harbor Jan 23, 2025, 1:17 AM

#

Yeah some of the enemies are coded a bit strange

keen ruin Jan 23, 2025, 1:18 AM

#

well it makes sense how it's set up except for the fact that the skinned mesh renderer isn't a child of the body animator so the animator can't be culled properly, at least not easily

#

I gotta figure out if there's a way I can give it a fixed bounding box

ashen harbor Jan 23, 2025, 1:18 AM

#

Speaking of funny things not being culled

#

Cheese in the Cheese version of Slaughterhouse

#

XD

keen ruin Jan 23, 2025, 1:19 AM

#

are those in place of the meat hooks?

ashen harbor Jan 23, 2025, 1:19 AM

#

Yeah they replace the meat

keen ruin Jan 23, 2025, 1:19 AM

#

huh I see

#

idk if the meat itself is part of the tiles, but if it is, then I guess I really need to make that API where people can add renderers to tiles........

ashen harbor Jan 23, 2025, 1:20 AM

#

I don't think it's gonna cause any issues, just found it funny

keen ruin Jan 23, 2025, 1:20 AM

#

nah it shouldn't

#

it's just inefficient

ashen harbor Jan 23, 2025, 1:20 AM

#

Yeah

keen ruin Jan 23, 2025, 1:21 AM

#

what does the replacement? is it built into the slaughterhouse plugin?

ashen harbor Jan 23, 2025, 1:21 AM

#

Yeah it uses JLL, so the cheese version is on Slaughterhouse, there's also a unique version of Slaughterhouse that Nikki did for Bozoros

#

It's tag based

keen ruin Jan 23, 2025, 1:22 AM

#

hmm, then I wonder when it does the replacement

#

there definitely should be a way to do it before CullFactory activates

#

assuming that the meat is not a SpawnSyncedObject for some reason anyway

#

I guess I should look at this

ashen harbor Jan 23, 2025, 1:22 AM

#

@swift token how does it trigger the tag based stuff again?

#

Wesley told me how it worked once but I forgot

#

lol

keen ruin Jan 23, 2025, 1:23 AM

#

(speaking of the cheese replacement on Slaughterhouse to be specific, so you don't have to read up)

#

oh they are SpawnSyncedObject, I wonder why thonk

swift token Jan 23, 2025, 1:31 AM

#

ugh probably a better question for nikki than me. i'm pretty sure it's using some combination of multiple of my scripts connected through unity events. I'm pretty sure it's just enabling or disabling different meshes based on the value of the config and a level filter to read the tag

keen ruin Jan 23, 2025, 1:31 AM

#

ahh, gotcha

#

good to know

swift token Jan 23, 2025, 1:35 AM

#

keen ruin oh they are SpawnSyncedObject, I wonder why <:thonk:842761533063036938>

iirc it was because it's using the script from the hanging spider corpses and that needed to be spawned as a network object to work?

keen ruin Jan 23, 2025, 1:36 AM

#

oh, I didn't know those had a script

ashen harbor Jan 23, 2025, 1:37 AM

ashen harbor Yeah according to Nikki she did the normal meat manually but forgot to for the c...

not sure what this means tbh

but anywho, just checked, the meat isn't part of the tiles so it can't be culled in any case

#

it's probably not a huge deal really

ashen harbor Jan 23, 2025, 1:38 AM

#

this

keen ruin Jan 23, 2025, 1:38 AM

#

oh that

#

sure

#

ideally they aren't SpawnSyncedObject since they don't have any player interaction other than pushing, but idk, maybe the pushing is networked

#

that would be kinda funny if it was but maybe zeekerss set it up that way

ashen harbor Jan 23, 2025, 1:39 AM

#

@copper cosmos is that how Zeekerss set it up?

keen ruin Jan 23, 2025, 1:39 AM

#

buh

#

I was about to say, it's probably not so important as trying to figure out how to cull more animators in the interior, then maybe make the meat physics go dormant more easily, if they are not doing that already

#

animation culling crap is kinda on me, I need to generalize the solution I use in Black Mesa

#

doors thing might be able to be a general mod for all interiors (if I can detect whether the doors don't have an idle animation), but the lights thing is a bit more involved and probably where the majority of the performance loss lies

#

Slaughterhouse has about as many animators as Black Mesa did, and generation is probably smaller too 😅

ashen harbor Jan 23, 2025, 1:43 AM

#

Yeah Slaughterhouse is quite a bit more optimized now though since it is now making proper use of Dungeon Generation Plus lol

keen ruin Jan 23, 2025, 1:45 AM

#

since when you do you mean? I don't think that would affect framerates at all

ashen harbor Jan 23, 2025, 1:46 AM

#

It helped cus the interior had a lot of light sources and shadows lol

#

So you'd almost always reach the shadow limit before unless you used low shadow mode

keen ruin Jan 23, 2025, 1:47 AM

#

ohh, you mean that it's using DunGenPlus to increase the shadow limit?

#

I would hope that running CullFactory would effectively prevent hitting that limit

#

but increasing the limit isn't really an optimization, it's just a way to get Unity to shut up

copper cosmos Jan 23, 2025, 1:50 AM

#

Pushing the objects has to be networked or it just doesn't let you push them at all. That said only the initial transform is synced, they aren't like, constantly checking transforms and syncing it or anything.

keen ruin Jan 23, 2025, 1:51 AM

#

huh, that's interesting that it requires that

#

I guess that it kinda makes sense to make the thing move semi-consistently across clients, but it's unfortunate for them all to be exempt from culling

#

I forgot what the component is that does the pushing though

copper cosmos Jan 23, 2025, 1:52 AM

#

It's an easy fix on my end to add the LOD Culling for the model, I just forgot and really don't feel like Unity rn

#

And it's a non issue ultimately since it will only affect a slight bit of performance on Gorgonzola

keen ruin Jan 23, 2025, 1:53 AM

#

sure yeah

#

generally triangles aren't really the issue as much as objects being processed though, so CullFactory taking care of it will usually be more efficient than LOD culling I think

#

and more correct

#

anyway, not saying you need to change that, it's fine

#

I did the same thing for the barnacles

copper cosmos Jan 23, 2025, 1:54 AM

#

Yeah makes sense

keen ruin Jan 23, 2025, 1:54 AM

#

at some point I really gotta get that animation stuff working for you though, it seems like that would be quite beneficial

#

the light thing would probably take some explaining, and depending on how many light prefabs you have, a bit of tedious reworking, but it should help a lot since for whatever reason HDRP lights do a bunch of random work in LateUpdate() if they had an animator parent when they Start()ed

green gust Jan 23, 2025, 3:15 AM

#

I did notice a weird light warning spam a while ago while I was testing jimothy

#

I gave one of his objects two colliders that were inside eachother, stood inside one and pointed thr camera towards the inner one

#

Then the light warning from hdrp kept spamming

keen ruin Jan 23, 2025, 5:04 AM

#

definitely shouldn't have anything to do with colliders, what interior was it?

#

and also was CullFactory disabled?

green gust Jan 23, 2025, 5:06 AM

#

keen ruin definitely shouldn't have anything to do with colliders, what interior was it?

just normal factory

green gust Jan 23, 2025, 5:06 AM

#

keen ruin and also was CullFactory disabled?

prob not

keen ruin Jan 23, 2025, 5:10 AM

#

green gust just normal factory

oh very odd, I wonder if something in your mod could have been making extra lights? zeekerss has the lights set to fade at a good distance to where it's incredibly unlikely to see that error

#

or perhaps impossible, not sure

green gust Jan 23, 2025, 5:11 AM

#

i mean it was only spamming it when i moved my camera to look at the inner collider while i was inside the outer collider, so idk what was going on there tbh maybe something with the player's own light but im just talking out of my ass here

keen ruin Jan 23, 2025, 5:14 AM

#

well it it was the shadow count warning it shouldn't be related to the player light

#

hard to say

green gust Jan 23, 2025, 5:18 AM

#

i have also noticed this before btw

#

one time i was either spectating or just playing with @limber elm, and i was looking at logs and everytime i looked at her hair cosmetic it just spammed the shadow warning lol, other people in the lobby also noticed this happening, it was pretty funny

#

hasnt happened since, i think anyway

green gust Jan 23, 2025, 5:44 AM

#

also do u plan on making black mesa depend on this one? cuz it still depends on the old one

keen ruin Jan 23, 2025, 5:52 AM

#

it's gonna be merged to stable eventually

green gust Jan 23, 2025, 5:52 AM

#

icic

keen ruin Jan 23, 2025, 5:55 AM

#

probably not long before then actually, since I can just add patches to stable as I make them

#

fyi, made an oopsie with the PathfindingLib plugin GUID in 0.0.4, so if you install that version, PathfindingLagFix Beta 2.0.5+ will stop working

#

lyric hedge Jan 23, 2025, 6:41 PM

@keen ruin I can't remember if I've asked this before, but will you be updating PathfindingLagFix or will you be uploading this version as its own thing?

keen ruin Jan 23, 2025, 6:42 PM

it's going to become v2 of PathfindingLagFix

keen ruin it's going to become v2 of PathfindingLagFix

Gotcha

keen ruin Jan 23, 2025, 6:43 PM

once I'm satisfied with it (probably will be quite soon), I will push it to stable as 2.0.0 and deprecate beta

AWESOME

keen ruin Jan 25, 2025, 2:58 AM

#

I have unlocked a new power, I am a MonoMod enjoyer now

#

I should have an update for PathfindingLib soon ™️ that makes it so that all the async pathfinding only has to pause when doors are locked/unlocked rather than doing it every frame

green gust Jan 25, 2025, 2:59 AM

#

all it took was being in vc with matty?

keen ruin Jan 25, 2025, 2:59 AM

#

now instead of just decompiling C# assemblies I will be peering into the depths of the x86 world

#

lmao well Matty helped a lot yeah

crimson jolt Jan 25, 2025, 2:59 AM

#

keen ruin I have unlocked a new power, I am a MonoMod enjoyer now

is this the one that required you to run hookgenpatcher

keen ruin Jan 25, 2025, 2:59 AM

#

nope

#

I wouldn't use hookgenpatcher ever lol

crimson jolt Jan 25, 2025, 3:00 AM

#

ah

#

i get it confused with something else

#

melonloader i think

#

i dont remember

keen ruin Jan 25, 2025, 3:00 AM

#

but I can generate hooks into native methods using MonoMod's APIs

crimson jolt Jan 25, 2025, 3:00 AM

#

ahh

keen ruin Jan 25, 2025, 3:00 AM

#

I mean MonoMod is what enables HookGenPatcher, it's just a lil wrapper over the MonoMod APIs

#

but basically I found a function in UnityPlayer.dll that applies the carving results on the main thread, hooked it, checked if it had any changes to apply to the navmesh, then locked the navmesh for writing only then

#

before, I was using two new subsystem in the player loop to wrap the AIUpdate subsystem in write locks

#

and also telling all jobs to pause at the start of the frame

#

on average they were probably losing like 1ms of working time per frame

#

maybe a little more

#

overall the patch isn't too complicated, I shall commit it momentarily if you want to look

keen ruin Jan 25, 2025, 4:08 AM

they can't damage players properly when on them and when they drop down they don't path towards players

does this happen for everyone always?

Reduced blocking of the main thread by hooking into the Unity runtime to detect when carving obstacles will make changes to the navmesh.

i've dug though the documentation for the NativeDetour and, while i highly doubt anybody else will try to hook into the same function as you,
only one NativeDetour can exist for each function pointer.

keen ruin Jan 25, 2025, 9:21 AM

hmm I wonder though

#

if I change carving with that version I should have deadlocked

tardy pivot Jan 25, 2025, 9:22 AM

#

not necessarily if there was already a job running

#

and if no job ever started then the lock would still be free

keen ruin Jan 25, 2025, 9:23 AM

#

jobs were running but yeah I suppose if there is one of these bad ones in flight it lets the main thread run again

#

eh

#

I won't worry about that rn

tardy pivot Jan 25, 2025, 9:24 AM

#

in any case we caught it before it has became a problem

keen ruin Jan 25, 2025, 9:36 AM

#

lmao @green gust I see why it is so unlikely to crash with your Jimothy guy

#

to be clear this is with a lot lot lot of them, but the point is that the physics updates are taking really long due to all the trigger colliders

#

PlayerPhysicsRegion and EnemyAICollisionDetect

green gust Jan 25, 2025, 9:37 AM

#

hmm

keen ruin Jan 25, 2025, 9:37 AM

#

perhaps you need to set some layer exclusions on them, but I might also want to look into optimizing those OnTriggerStay() handlers to not alloc

green gust Jan 25, 2025, 9:37 AM

#

ontriggerstay on jimothy?

keen ruin Jan 25, 2025, 9:37 AM

#

although I'm not entirely sure what is allocating

#

yes

green gust Jan 25, 2025, 9:38 AM

#

i dont think he has any

#

i could be crazy

keen ruin Jan 25, 2025, 9:38 AM

#

on PlayerPhysicsRegion and EnemyAICollisionDetect

green gust Jan 25, 2025, 9:38 AM

#

ah, zeekerss stuff

keen ruin Jan 25, 2025, 9:38 AM

#

not sure if he has the collision detect but definitely the physics region

green gust Jan 25, 2025, 9:38 AM

#

i could just replace em with my own script

keen ruin Jan 25, 2025, 9:38 AM

#

you're in control of the collider tho

#

nah

green gust Jan 25, 2025, 9:38 AM

#

yea

keen ruin Jan 25, 2025, 9:38 AM

#

if you replace PlayerPhysicsRegion you're on your own lmao

green gust Jan 25, 2025, 9:39 AM

#

Kek

keen ruin Jan 25, 2025, 9:39 AM

#

optimizing it may be worth something though

#

and also make sure you have all layers excluded except the ones that are relevant

green gust Jan 25, 2025, 9:39 AM

#

well i dont really do transpilers or patches to stuff like that usually lol, but i can mess with the collider

#

i need to go through all the things i add and mess with their colliders

#

there's a lot

#

i also need to make my gal colliders like, a lot less

#

i think i used to put a static collider for each of their armature bones

#

to be fair it's accurate Kek

keen ruin Jan 25, 2025, 9:40 AM

#

yeah I mean my looking into optimizing those OnTriggerStay methods

keen ruin Jan 25, 2025, 9:40 AM

#

green gust i think i used to put a static collider for each of their armature bones

for what purpose? taking damage?

green gust Jan 25, 2025, 9:40 AM

#

nope, just for standing on em like collision and stuff

keen ruin Jan 25, 2025, 9:40 AM

#

oh

#

you're supposed to be able to stand on their shoulders??

#

that seems a bit overkill lol

green gust Jan 25, 2025, 9:41 AM

#

its useful sometimes

keen ruin Jan 25, 2025, 9:41 AM

#

but you might be able to make those only physical collision and not trigger any callbacks, not sure if that would be the default behavior for those

green gust Jan 25, 2025, 9:41 AM

#

one time i was drowning, so i stood on their head and jumped away

#

ye they're just static colliders

#

so no trigger stuff

#

im gonna have to check the exclude etc stuff for scannodes and whatnot layer

#

later*

#

that's gonna be a bit tedious

#

cuz they also use colliders (which i assume need to be trigger but i could be wrong)

#

also i guess if a trigger collider is only for when zeekerss is doing a sort of overlapsphere

#

it can just exclude everything?

keen ruin Jan 25, 2025, 9:46 AM

#

main thing you need to do is exclude everything irrelevant on your physics regions and collision detects

#

#

you're getting triggers on your own colliders

#

this is with just one jimothy

#

(zeekerss should also add exclusions.....)

#

(but thankfully it is just the elevator....)

keen ruin Jan 25, 2025, 10:22 AM

#

uploaded the hotfix for not taking the read lock in PathfindingLib 0.0.7, and also tested CodeRebirth on March with carving and navmesh generation running every frame and things seem fine

#

also added profiler markers to verify that the jobs are pausing, they are indeed doing so the same as my job in PathfindingLagFix so we should be good @green gust

green gust Jan 25, 2025, 10:22 AM

#

yippee

keen ruin Jan 25, 2025, 10:42 AM

#

god the fact that I was able to get this working with the minimal amount of thread waiting possible so easily makes me really question the Unity devs' judgement for not doing so themselves

#

like this could just be one mutex and condition variable in their code and a few locks around the navmesh writes and then it never crashes again

#

if I'm able to hook in and do this they could do it even more easily

tardy pivot Jan 25, 2025, 10:46 AM

I sent Wesley the log I think

#

Should be it

keen ruin Jan 25, 2025, 12:35 PM

#

hmm, nothing shows up searching for the obvious keywords

#

but it's also possible that I incidentally fixed this in a commit that I haven't uploaded to thunderstore yet, I'll have to check in a bit

tardy pivot Jan 25, 2025, 1:19 PM

#

keen ruin I'll have to see how those look, it's meant to be a pretty low level API

here: https://github.com/mattymatty97/LC_PathfindingLib/commit/a3b662521d28fd471d28bba1a229601377ef3fbd

it still is a LowLevel API but now it should be Reentrant ( recursive ) and also check the validity of the operation. so it's not possible to Release a lock if you're not holding it

GitHub

Improve safety of ReadersWriterLock.cs by tracking the state for ea...

… thread and depth of recursion

#

i cannot test it atm so i might have made some mistakes but the idea is there

#

the impact should be minimal if not none as the operations added are really simple

keen ruin Jan 25, 2025, 1:42 PM

#

hmm, I see

#

I tend to think this is unnecessary on some level though, since I can prevent being in the wrong state by just asserting that we are on the main thread or not

tardy pivot Jan 25, 2025, 1:44 PM

#

you can assert it but assertions will be stripped out on release and this is a public api.

#

plus you yourself managed to break it previously with the yield w/o Begin

#

that meant you had the reader count negative in some moments

keen ruin Jan 25, 2025, 1:45 PM

#

fair point

tardy pivot Jan 25, 2025, 1:46 PM

#

i highly doubt this few checks will cause any measurable impact in performance

#

and even then the security gain would be worth it imo

keen ruin Jan 25, 2025, 1:53 PM

#

the one big misgiving I have right now is that I vaguely remember trying ThreadStatic for something a while ago and it performed pretty badly for some reason

#

I guess in this case I should just record the time to check these things before and after, but I wonder if there is a better way

tardy pivot Jan 25, 2025, 1:55 PM

#

ik ThreadLocal is quite bad for performance

#

i tried to google ThreadStatic but found noone that did performance comparsions

#

only thing i found is that ThreadStatic perform a lot worse in Debug builds than in Release

#

from stackoverflow

Stack Overflow

.NET: ThreadStatic vs lock { }. Why ThreadStaticAttribute degrades ...

I've written small test program and was surprised why lock {} solution performs faster than lock-free but with [ThreadStatic] attribute over static variable.

[ThreadStatic] snippet:

[ThreadStatic]

keen ruin Jan 25, 2025, 9:13 PM

#

ah right, that could make sense maybe

#

I'm assuming that means the CIL optimization level though, my "debug" builds are still optimized, just with profiler markers added

keen ruin Jan 25, 2025, 10:22 PM

#

wait also @tardy pivot how would your commit handle multiple ReadersWriterLock instances? if we're gonna be expanding the functionality of the class it should not assume that there's only one

#

we would probably need to protect a dictionary with the mutex wouldn't we?

#

anyway, I can add a simple check to make sure that the readersActive doesn't go below zero at least

tardy pivot Jan 25, 2025, 10:33 PM

#

i mean that lock was used as a static class to begin with 😅

if you want to allow multiple separate instances then all the statics need to become instance field and instead of ThreadStatic attribute use the ThreadLocal<T> objects

keen ruin Jan 25, 2025, 10:35 PM

#

the lock instance was in a static class

tardy pivot Jan 25, 2025, 10:35 PM

#

yeah i meant that we create only one instance of it

keen ruin Jan 25, 2025, 10:36 PM

#

sure, but in that case I might as well make everything involved in the locking static

#

then at least it's obvious that it can only be used once

#

I would rather keep the class form, and I can make protections for these things through throwing exceptions based on the information that already exists rather than creating that limitation

tardy pivot Jan 25, 2025, 10:37 PM

#

converting them to threadlocals is not difficult butbi'm unsure about the performances in that case

keen ruin Jan 25, 2025, 10:37 PM

#

if readers are only ever on different threads than writers, the check for taking a read lock within a write lock and vice versa can never happen

#

(which we can safely say should always be the case)

#

main thread can always safely read the navmesh, it doesn't need to take the lock for that, so I don't want to allow it

tardy pivot Jan 25, 2025, 10:38 PM

#

keen ruin I would rather keep the class form, and I can make protections for these things ...

i mean we can keep it as it is rn tbh. if anybody breaks it it's their fault anyways

keen ruin Jan 25, 2025, 10:38 PM

#

yeah

#

I mean I can make the assertions into exceptions probably as well, I just have to check the cost of determining if we're in main thread

#

it's probably very minimal

tardy pivot Jan 25, 2025, 10:39 PM

#

only check we should implement somehow is the recursion. as it is possible to acquire the write multiple times i belive 🤔

keen ruin Jan 25, 2025, 10:40 PM

#

I looked up some discussion about performance of ThreadStatic vs ThreadLocal, and people were saying that ThreadLocal performed badly, so I think if I were to make those protections I would create my own data structure to keep track of that

keen ruin Jan 25, 2025, 10:40 PM

#

tardy pivot only check we should implement somehow is the recursion. as it is possible to ac...

that's protected through NavMeshLock, nobody is using ReadersWriterLock

#

write lock can only be taken by main thread, and it has a "thread local" in the form of a static field for the depth

tardy pivot Jan 25, 2025, 10:41 PM

#

oh uh? ok

keen ruin Jan 25, 2025, 10:41 PM

#

only main thread can read from that field by nature of it being behind an assertion

tardy pivot Jan 25, 2025, 10:44 PM

#

sure then there is no need to change anything tbh.

#

it's a matter of performance vs security
or more precisely caring to gracefully fail if a 3rd party uses the api wrong

keen ruin Jan 25, 2025, 10:51 PM

#

yeah

#

the assertions should definitely be enough

#

and also performant

tardy pivot Jan 25, 2025, 10:54 PM

#

👍

keen ruin Jan 26, 2025, 1:09 AM

#

@ashen harbor some part of the strange behavior with the centipedes seems like it may be caused by the async player targeting patch, I'll have to rethink that one I believe

#

not sure what would have caused it to do no damage and not want to detach though

#

the issue I'm observing is that because the first result from calling TargetClosestPlayer after it has attached to the ceiling with no one inside will say that no player is targetable, it immediately goes into retreat mode until the next time it drops

#

however, I can't really seem to get it so that the centipede doesn't do damage yet

keen ruin Jan 26, 2025, 9:10 AM

#

looks like maybe the check for main thread was actually causing exceptions on release builds, but it wasn't outputting any of them sad

#

just pushed an update to just roll a new function for this check instead, should work again

#

in v0.0.10

green gust Jan 26, 2025, 9:11 AM

I love exceptions that don't get outputted

#

How does that even happen

keen ruin Jan 26, 2025, 9:17 AM

#

I don't know lmao

#

I wish I knew

#

unless maybe it would show up in Player.log, I could try to check quickly

tardy pivot Jan 26, 2025, 9:18 AM

BepInEx only collects unity logs from main thread. everything else goes to the Player.log only

I get logs in the console from other threads tho

tardy pivot Jan 26, 2025, 9:19 AM

#

yeah guess I know where to go if something weird is happening in my jobs

#

(if I see the exceptions there, I will check now)

#

I'm guessing maybe CurrentThreadIsMainThread() just returns true in all cases in release, maybe your decomp could tell you Matty

#

since I don't have the release UnityPlayer.dll decomped yet

tardy pivot Jan 26, 2025, 9:21 AM

i've pondered if to patch it in AsyncLoggers in the past then decided to leave it as original

not sure tbh

keen ruin Jan 26, 2025, 9:30 AM

also I am currently very confused, I switched it back to using UnityEngine.Object.CurrentThreadIsMainThread() again and it is not failing to run the jobs anymore

#

I must've goofed something before

tardy pivot Jan 26, 2025, 9:30 AM

#

prob because it's in a preloader and it should not load the classes until needed

keen ruin Jan 26, 2025, 9:31 AM

#

wait but wouldn't the Application class be loaded by using its nested class?

#

and also by getting the method via reflection?

tardy pivot Jan 26, 2025, 9:32 AM

#

yeah but that method is called after unity boots. but it's loaded before

cold peak Jan 26, 2025, 9:33 AM

#

reflection used to support old unity versions

tardy pivot Jan 26, 2025, 9:33 AM

#

or that..true

keen ruin Jan 26, 2025, 9:34 AM

#

huh, because of overloads?

#

but I guess I don't know how an overload would not also cause errors with reflection if they aren't providing parameter types

cold peak Jan 26, 2025, 9:35 AM

no, because RegisterLogCallback is for 4.0.0-5.0.0 unity versions

keen ruin Jan 26, 2025, 5:10 PM

yeah I'll probably do that or make a linked list of thread data like the .NET one does, later

#

first things first, I gotta back it out to remove the exceptions

I don't have time to fully fix the safeties

I also am very curious why it would be thinking it's running on the main thread though

tardy pivot Jan 26, 2025, 5:33 PM

linked list will probably be worse in performance than statics tbh

keen ruin Jan 26, 2025, 5:35 PM

#

for sure, but it should only be one extra comparison over the static implementation

if it is implemented as a static class though, I would tend to say it should just be in NavMeshLock instead of split off in another class, since it can't be reused anyway

at least not without copying it

#

imo the beta is pretty stable now

#

there was a lot of concern with crashes in the earlier versions but i haven't encountered any so far (since v2.0.4)

#

i think it's just getting new features ATM that are preventing it from leaping to stable release yet

green gust Jan 27, 2025, 2:31 AM

nod

safe ember Jan 27, 2025, 2:32 AM

#

thought alright

keen ruin Jan 27, 2025, 2:51 AM

#

yeah the difference is very significant between stable and beta, beta is effectively a total rewrite and it is more of a performance mod than a bandaid fix

#

the longest-running parts of most AI in the game (at least the ones that have been patched) run off the main thread in the beta

#

also yeah, mainly trying to ensure that AI is totally functional and behaves as intended before I push to stable, had a mishap with one of the patches that I was trying to avoid specializing, so for now that one is disabled to see if things are fine without it

main things I need to know are whether any AI behaves in an unexpected way or becomes stuck

keen ruin Jan 27, 2025, 10:13 PM

yeah I'm not sure when the AI is supposed to switch out of that mode, but the maneater is intended to sneak around near the player when you're within a certain area

it's one of the most complicated AIs in the game I think

somber lily Is it really that bad 😅

shitty in a good way

steep tartan idk what to say, he was dumber than usual

masked are kinda buggy in vanilla ever since v60 so im not 100% sure if this is related to pathfindinglagfix

Haha, gotchya. I appreciate that 😁

they act super weird now ever since the mineshaft elevator changes

#

crimson jolt they act super weird now ever since the mineshaft elevator changes

yeah, they were more menacing

#

but it's strange how they behaved this time, they didn't even try to get to the ship

steep tartan on rend he saw me and just gave up chasing me to the ship

hmm, I don't think that could have been a PathfindingLagFix bug, I don't currently patch anything that should affect the masked unless it was patrolling instead of actually trying to chase you

#

I appreciate you looking out for bugs nonetheless, anything out of the ordinary is worth letting me know about

keen ruin hmm, I don't think that could have been a PathfindingLagFix bug, I don't current...

So I've ran into a couple cases where Spiders kinda start glitching out and start moving really weirdly, once was in Mineshaft and once was when a Spider was chasing someone and they left through a Fire Exit, so I would guess when they lose track of the original person they're targeting their ai just janks out

#

They just kinda start spinning and rotating as they move, and fighting them becomes difficult cus their hitbox becomes inconsistent 😂

do you know how long that was after the spider spawned? I wonder whether it was still trying to place webs

#

I feel like I've seen spiders spin in place in vanilla, but I can't say I'm sure

ashen harbor Jan 29, 2025, 5:42 AM

#

keen ruin do you know how long that was after the spider spawned? I wonder whether it was ...

Possible

keen ruin Jan 29, 2025, 5:43 AM

#

the only thing I change that should affect spiders in the current version is the patrolling code, which in theory should mean that any other patrolling enemy could exhibit the same behavior if it's caused by PathfindingLagFix

#

and I think there are other mods that do several fixes for the spider AI right? I wonder if any of them address that if it is a vanilla bug

#

anotha update

Version 2.0.9 (Beta)

Reintroduced the async player targeting patch with changes to ensure that enemies don't instantly give up the chase when first checking if a player is accessible.

#

this is a general patch once again, so lemme know if enemies that chase the closest player behave strangely

#

in theory, centipedes should no longer run away from you after you trigger them (they chased me in my testing), since I have made it so that it does player targeting synchronously if the last asynchronous result is stale

ashen harbor Jan 29, 2025, 6:03 AM

#

keen ruin in theory, centipedes should no longer run away from you after you trigger them ...

Noice 😄

#

I'm just glad the past few updates have been pretty stable, hopefully that means you can finally bring it out of beta soon

keen ruin Jan 29, 2025, 6:17 AM

#

yeah I'm thinking that if there are no issues with enemies getting stuck or anything in this version I will bring it to stable and then start another minor release in beta

#

but I'll have to have a look at all the enemies to see which ones are the worst with the roaming and targeting already patched

#

feel free to suggest ones to look into

Might be something with #1298542667390779413 and how I tilt spider on slopes?

#

Or if it's turning back and forth it might be something with pathfinding.

ashen harbor Jan 29, 2025, 7:04 AM

#

wanton salmon Or if it's turning back and forth it might be something with pathfinding.

I was gonna guess maybe a bug with Natural Selection cus it happened after adding that if not PathfindingLagFix but yeah it kept turning back and forth while moving

keen ruin Jan 29, 2025, 7:11 AM

#

oh "while moving" as in it was actually going somewhere?

ashen harbor Jan 29, 2025, 7:12 AM

#

keen ruin oh "while moving" as in it was actually going somewhere?

Yeah, and while chasing players.

keen ruin Jan 29, 2025, 7:13 AM

#

ohh okay, that's interesting

#

I'll have to see if I can repro anything like that in LAN I suppose

wanton salmon Jan 29, 2025, 12:26 PM

Natural selection with safe mode doesn't affect spider at all so it has to be something with Spider position fix.

Hey it seems Pathfinding really hates surfaced creatures

#

Mantis shrimp and Horseshoot crab are throwing lots of asynchronous path stuff in the console

I only noticed it towards the end, as I was going to moons where I had already set them to spawn in

Just noticed it also applies to Cancerous Rodent

will have a look

but also

ewwww

#

that mod is so unbelievably outdated the beta makes it doubly obsolete

#

oh you're talking about the debug log

#

it's not really that PathfindingLagFix dislikes those enemies, although I certainly wouldn't have expected them to be running target checks infrequently enough that that message spams

#

that is definitely a bit curious
