Also, Louis was incapitated in a pile of acid and Zoey stood on top of it, trying to revive him. That never happened to me before.

It's never happen to me without this addon. Usually they'd just move.

They do that without this addon. I didn't say it fixes every issue with them. The modding system for this game is extremely limited.

This didn't even improve them. It actually made them dumber. I was playing Dead Air; I threw a molotov, and Bill just stood in the fire.

can you make a zombie infection mod. when the players died,they turn into infected
Ziggy  [author] Dec 20, 2016 @ 10:48pm 
No

@Ziggy Does this work in Online multiplayer games, even if the other players don't have this addon?
You died Dec 11, 2016 @ 3:33am 
Can bots use pipe bomb, pile???

Hosting local servers with this mod enabled has a bug where the bot get kicked and replaced with a stationary L4D2 survivor model if a player leaves during end-of-level transitions. Manually changing sb_transition from 0 to 1 in the file fixes this, but this isn't in the workshop release

So, does the advanced mod give the "Stay here!" commands and the simple doesn't?

PsionicArchon Nov 8, 2016 @ 3:21am 
Not sure if you're still supporting this but I'll throw this out there anyways. Every so often this mod will cause my dedicated server to crash when transitioning to the next map.

It happens more frequently on custom maps. We'll get to the safe room, start loading the next segment and, boom, crash. There are no other addons running on the dedicated server.

"• Bots will try to stay in a tighter group with the player." - I don't like this feature at all. They are CONSTANTLY getting shot, as they tend to jump in front of my barrel over and over again. Ziggy, please, could you consider removing this feature? I BEG YOU! Let them give me some space to breathe! :(
RainingMetal Oct 25, 2016 @ 2:57pm 
The command sb_toughness_buffer doesn't seem to do anything for me (I followed your example and made my own mod that simply increases the AI reaction time and treats temporary health like normal; I don't want them to lead or use melee weapons). No matter what value I put in that code, a survivor bot will always use up their health kit when they're incapacitated.

Any idea how it works?
Metalloman1 Oct 23, 2016 @ 9:44pm 
Good to know, thanks for your reply and thanks for your mod! :D
Ziggy  [author] Oct 23, 2016 @ 8:54pm 
Impossible to implement. I cannot allow the bots to do anything new that they can't already do in the vanilla game. I can only tweak settings of already-existing behaviors. For things like bots using melee weapons and closing the safe room door, those features already existed in the game but were simply disabled.
Metalloman1 Oct 23, 2016 @ 8:28pm 
Oh, I see, well, that wasn't a big issue, I just had to sit and wait, eheh! Thanks anyway! :D


Just to know: Will ever be the chance to see bots using throwing weapons, heavy machine guns, chainsaws and turrets or this is impossible to implement?

Thanks again for your answers, @Ziggy! :)
Ziggy  [author] Oct 23, 2016 @ 8:09pm 
That is a bug with the vanilla game, not caused by this addon. The AI for the bots is coded very poorly and there is nothing I can do about that, unfortunately. The modding system for this game is very limited.
Metalloman1 Oct 23, 2016 @ 3:49pm 
@Ziggy, using this mod and it's really nice so far! :)

Had a little issue one time when I got killed, the other survivors continued their quest until they found me trapped in a room. They were unable to open the door and I had to wait 10 minutes while zombie hordes and special infected continued spawning. After that time they finally managed to open the door and free me, but it was really strange to see them "using" the door and the door remaining close.
Probably something related to their position in front of the door?
Ziggy  [author] Oct 22, 2016 @ 3:47pm 
Just don't use the options that enable cheats then. You can unbind those keys after installing that addon and pretend like those options don't even exist.
whynotll82 Oct 22, 2016 @ 3:44pm 
i wanted to play vs without a button that turn cheats on
Ziggy  [author] Oct 22, 2016 @ 3:39pm 
That's not what this addon is for. The advanced version does allow you to do that, however.
whynotll82 Oct 22, 2016 @ 3:20pm 
please update so i can play vs mode with bots
Ziggy  [author] Oct 20, 2016 @ 4:00pm 
It is. But nothing in this addon should be causing that.
lolznoboz Oct 20, 2016 @ 5:26am 
@Keel the Swift i think that's a problem with rochelle's model not precached
Ziggy  [author] Oct 19, 2016 @ 9:42pm 
That's not something this addon would do.
lolznoboz Oct 19, 2016 @ 4:17am 
the bots are now in love with the jukebox
Keel the Swift Oct 14, 2016 @ 1:39pm 
Alright, tested hosting local server on Blackout Basement with Simple version of improved bots.

Crashed after safehouse:
109/ - info_transitioning_player: UTIL_SetModel: not precached: models/survivors/survivor_producer.mdl

Gonna double check with mod off.
SAM Oct 6, 2016 @ 8:06am 
I love this
Love Chocolate Oct 2, 2016 @ 4:57am 
Great!
Dr.Gaming Oct 1, 2016 @ 7:17am 
plus, the bots dont seem to pick up ANY melee weapons whatsoever. no matter the situation.
Dr.Gaming Oct 1, 2016 @ 7:15am 
that restarts the whole campaign...
Ziggy  [author] Sep 30, 2016 @ 8:01am 
You can go into the menu and vote to restart the map at any time. Since you are the only player the vote will pass automatically every time.
Dr.Gaming Sep 29, 2016 @ 3:55pm 
because its kinda boring to watch the bots and not do anything.
Dr.Gaming Sep 29, 2016 @ 3:53pm 
can you make a way to toggle the thing where they keep going even after you die?
lolznoboz Sep 25, 2016 @ 12:58pm 
my mutation server is singleplayer
Ziggy  [author] Sep 25, 2016 @ 11:50am 
It should work on any game mode as long as you aren't playing on a multiplayer server.
jefferson Sep 25, 2016 @ 5:11am 
its only works in campaign
lolznoboz Sep 25, 2016 @ 4:53am 
it don't work in mutation
SonRogumer Sep 24, 2016 @ 9:26am 
THANK YOU!
FlippyHalo Sep 3, 2016 @ 5:21pm 
i love this addon :3
Stewart Twinkletoes Aug 26, 2016 @ 5:33pm 
Could you make this addon compatibale with the admin menu addon? That would make my Left 4 Dead 2 experience more fun!
EternalMesa Aug 22, 2016 @ 1:09am 
ok so this mod conflicts with the weapon booster mod for some reason. does any one else have this problem because for me both of the mods are a must for when i am playing solo because i suck. if this is a regular thing is there a way i can fix it?
Niiro Kitsune Aug 16, 2016 @ 10:14pm 
Ok fixed: I had to run the game, disable ALL my enabled mods, restart the game, start a game with the Improved Bots mod ONLY, restart the game, re-enable my desired mods, works great now, thanks for the insight and for making this!
Ziggy  [author] Aug 15, 2016 @ 10:51pm 
If the bots don't continue to play after you've died then something is preventing this addon from working. Are you sure the addon was enabled when you were playing? If you subscribed to it then launched the game and immediately started a game you may have not allowed enough time for Steam to download and install the add-on (which it doesn't do until you've launched the game).
Niiro Kitsune Aug 15, 2016 @ 8:06pm 
Installed this today, but I've never once seen the bots use melee weapons, and the bots definitely do not continue when I die. As far as I can tell, this mod doesn't work, which is a shame cuz I'd really love it to. There are no conflicts with any other mod i have installed. I've only really tried it in single-player but that's all I intend to use it for.

Any insight on this?
Floxianable Aug 3, 2016 @ 6:57pm 
This is easily the most essential mod to the game, Id rather play the game with this and no other mods than a bunch of add on campaigns and skins etc. Outstanding work, man.
[ASCL] LIX Jul 28, 2016 @ 1:54am 
Bots don't even carry melee weapons. What happend here? I have a slow zombies mod removing specials but there was no conflictions.
Doomguy { GENOCIDE } Jul 21, 2016 @ 5:12am 
Cool mod but it's a shame that it can't work with Infinite ammo script :(
Krasunir Jul 15, 2016 @ 8:57am 
Oh. That sucks.
Ziggy  [author] Jul 15, 2016 @ 8:55am 
Not something I can do due to the limited modding system this game has.
