here is the bus navmesh bug

https://steamproxy.com/sharedfiles/filedetails/?id=3597807102

one Navvmesh bug is on no Mercy chapter 1, when the big bus spawns near the alarm car area, the survivor bots will not pathfind around it. they will try to path find "through" it

@ArrayOfHopeLive
if you report that, i'll check and fix it

i do love this mod so much, the random paths this mod lets me take is so much fun! i just hope that some of the "navmesh" issues with the objects get fixed, there are some maps where the infected and survivor bots just have serious trouble navigating

有些情况下，改变了路线，BOT会卡主

How can I disable this addon. I tried deleting it but it doesn't work

Good mod, a breath of fresh air. Better with other players. It does say beta so I think navmesh on new objects/obstacles still needs polishing. I made sure that I don't have mods that messes with navmesh.

I do test it with All 8 Survivors Sourcemod and Left4Bots 2 mod's command, typing "bots lead" on game chat. They are able to lead up to the safehouse in some walkthroughs of the same campaign map but not always. Sometimes there are obstacles that player bots and infected bots can't seem to recognize. On those instances, I just either use bots follow or bots warp on game chat.

The one that I mostly tested so far is just Dead Center's Streets. The bots can't recognize the fallen trailer truck that we encounter after we leave the safehouse. Also the fence outside the safehouse of the end of the stage. There could be far more changes to environment that I haven't encountered yet but those 2 are the only ones that bots can't recognize on Dead Center's Streets.

Is there a way to remove the panic event you included in NM Map 1? I love what this mod does, but I think that part should just outright be a seperate addon.

when using this another script of yours https://steamproxy.com/sharedfiles/filedetails/?id=2518360781
the alarm door in the rooftop of chapter 5 in no mercy usually spawns an horde at the beginning of the chapter when ur inside the saferoom, and once you get outside, the alarm door will be closed but the alarm doesnt active and neither spawns an horde if you open it.

Mankat, will there be a fix for The Sacrifice campaign?

Either use less mods or come back after L4D2 is updated to 64-bit.

A very, very cool mod, but my game crashes to the desktop without an error every second boot, it's a shame I had to write to unsubscribe.

Here to report a long time bug that's still existing, both of the RNG crescendo events introduced in ROS 2.0 can spawn l4d2 common infected (specifically the default population). Whether it is intentional or not, I hope to see it addressed soon.

Mancat, but here's a question: there is less randomness on The Sacrifice map in the same archive version of your mod from T A C M, there is more randomness, for example: on the first map, the transport always changed at the beginning and there was also a chance that the stairs would be closed. In the new version, only the white truck appears and the stairs are always open, or new carriages appeared between the brick factory and the train crash site, but now this is no longer the case.
So I wanted to know: is this a bug? Or did you disable part of the randomiser yourself?

P.S. If the update from 22 September has already fixed this problem, that's great! (I just haven't checked yet.)

@MANACAT just wanted to point out that the bots seem to be unable to follow over the front counter at the end of Dead Air Chapter 2. Might need to work on the nav a bit?

Amazing and have been using since initial release but I am pretty sure this is causing crashes for me fairly often. I think mostly on Dark Carnival, Hard Rain, Dead Air and Last Stand.

有时候（不知道是不是装了强化bot的mod）bot不会翻越随机生成的障碍物

this feels like vanilla!!! why? if you see developer commentary valve kinda implemented some map changes cemetery have some, dark carnival have some fences appear before the bumper car, dead center mall can change the alarm path, but it feels like valve did not go all in in to maps/objects change they just mentioned in developer commentary, this mod kinda feels like it add to the valve vision to be honest, one of the best mods on workshop, i use this one with the random alarm cars and it feels great, after over 10 years playing vanilla game its good to see more random things now olol

Dumb question: can this add-on change all of the official campaign paths depends on the players skills just like the vanilla dead center mall path-changes??

Crash dark carnival 4 map

@BENGIE linux? i have same problem. you should use archived version of this mod

Is this compatible with TACM?

and also why i can't Playing Hard Rain after Chapter 2?

crash sometimes on linux mint i dunno why?

This actually feels like something Valve would make!

The Sacrifice, 1 map, console:

I get frequent hard crashes attempting to load into the third level of Dead Air. It seems to be the only map I get this on.

This has been the message every time:

Note that if you've enabled the "Archived" mod, it will confused the bots to have their time teleporting to the other side of an invisible object. Disable that mod, or this mod prevent the bots from doing this.

In the campaign The Sacrifice half stopped working randomizer, namely on the first map (at the very beginning, where there are stairs, a fence should appear, but now it stopped appearing. Also disappeared carriages that appeared after the tank, where the bricks begin)

希望作者能够带来更好的改动设计

在官方地图中，感觉有些关卡并没有明显的变化

This is awesome! Just wanted to leave a comment in support, love stuff like this that keeps the game fresh.

Very fucking cool

@SP-Calamitas
1. I don't know what addons you are using. I think you'll be using left 4 bots, if you're using addons like nevfixes, remove that. I have verified that it is working properly.
2. it doesn't happen to me on No Mercy chapter 4. sadly, I can't fix something I don't know the cause of.

also, the 4th chapter of no mercy causes crashes. im not a coder, so i dont know the specifics, but the crashes are acknowledged in this reupload of your mod

https://steamproxy.com/sharedfiles/filedetails/?id=3456538394

navmesh in no mercy chapter 2 is broken, at the part where you made the pillar room into a smaller corridor; the bots will just stop at the entrance/center or will endlessly walk into a wall

Can you Make This Mod but Better? https://steamproxy.com/sharedfiles/filedetails/?id=2613303867&searchtext=TACM

This interferes with the Left 4 Bots (Improved A.I.) add-on:
https://steamproxy.com/sharedfiles/filedetails/?id=2279814689

The bots will just stand there in confusion in some maps.

The nav mesh is broken for me and I can not for the life of me figure out which addon is causing it.

uhhhh

@sniper
can you make that happen again anytime you want?

the fourth map on no mercy crashes when you die after the elevator part

if i use this mod, the game crashes very often... sad :(. it is really nice
