Thanks for linking the vid, and for this mod! As someone who literally just play with bots, this mod and sourcemod have really improved the experience with bots!

Thanks for linking to that video you found. I've added it to the description above to help others.

You shouldn't need that other file you linked to. I'm not using that and it's working fine for me.

@SapphireMedal Heh, turns out I simply had too many mods. I think all my mods simply took up too much memory. I deleted a VPK I cobbled together that was all hd textures for props, objects and general clutter, and now it's fine. I guess my recent mod binge of new weapons was just a bit too much with the included HD clutter.

Game now runs great, with both this mod and sourcemod. Sruvivors actually pick up all items, pass them to me if asked, revive with defibs, and I even have a plug in that gives me commands for bots to throw the various grenade types. It's really awesome.

It was surprisingly hard to find a decent written guide to installing sourcemod, but this video helped me:


Sourcemod only worked when I also added these files:


After that, it all works great and the bots are so, so much better! Kudos to Ziggy for this improvement, as well as linking sourcemod.

Dude1337 did you ever figure out how to fix it?
baddude1337 Apr 22 @ 9:47am 
Scratch that, seems Sourcemod is the problem. Been trying for a few hours and can't for the life of me to get it from crashing loading the next map in a campaign. It's a shame, as the bots picking up items, using defibs and throwing grenades is really awesome, and works on the first map until the crash.
baddude1337 Apr 22 @ 7:47am 
It seems even if I load a custom campaign with the console, it crashes as it loads the second map. Is this meant to happen? If so a real shame. As great as the bots are, I tend to play custom campaigns more often these days.

Thanks for this very much appreciated

madican Apr 15 @ 1:26am

madican Apr 15 @ 1:23am 
Yes,copyed from post and paste to listenserver.cfg!And in game when selecting character in the left writing "sv_cheats changed 0"
Ziggy  [author] Apr 14 @ 2:11pm 
Did you follow the additional steps in the description?
madican Apr 14 @ 12:48pm 
Cant change to another bot,when pressing F2 and selecting characters nothing happend(
Ziggy  [author] Apr 9 @ 8:12pm 
You'd have to start the game through the developer's console to get the advanced version working on community maps. You could just use the simple version for community maps instead.
Ziggy  [author] Apr 8 @ 8:37pm 
Not possible, as far as I know.
GabeCat64 Apr 8 @ 7:54pm 
Can you add the ability to select difficulty when using the single player menu?
Kelpo Gaming Apr 4 @ 3:00pm 
@mew Yes.
Mew1995 Apr 4 @ 10:28am 
@kelpo: at my game it worked, after pressing alt and then go to max. melee weapons (hope wrote it right XD) and set it on a higher amount then the picked melee weapons up. you also did the additional step in the info???
Kelpo Gaming Apr 4 @ 7:56am 
@mew: I tried that. Do you mean the dev console?
Mew1995 Mar 31 @ 12:18pm 
@kelpo: you need to press alt and then activate it with the commands
Kelpo Gaming Mar 30 @ 6:39pm 
I have a problem; the bots won't pick up melee weapons, even if I don't have one!
Mew1995 Mar 23 @ 2:08pm 
i found a bug with the versus singleplayer on the map swamp fever last stage, they wait only in the farm house without activating the checkpoint so you only must kill them. Hope for a fix in the new future :)
Sairus323 Mar 19 @ 10:17am 
Yep. Found the solution. I've started campain mode, not single player. also in scavenge bots without me can't win. i've tried dead center final in scavenge mode and they all just walked in circles around one spot and didn't even tried to take the canister.
Ziggy  [author] Mar 19 @ 10:03am 
Did you follow the additional steps in the description and are you starting the game through the new single player menu?
Sairus323 Mar 19 @ 9:20am 
i cant change character in game (console says can't use cheats). also i can't change gamemode: game sends me back to main menu. here the console log (i've tried to change to No Mercy realism mode):
-> Reservation cookie 0: reason netsupport
CAsyncWavDataCache: 221 .wavs total 0 bytes, 0.00 % of capacity
Duplicate sequence 3 in sheet file
BinkOpen( c:\games\steam\steamapps\common\left 4 dead 2\left4dead2\media\l4d2_background03.bik )
Dropped Sairus323 from server (Server shutting down)

I hope this helps to locate the problem...

Fafnir Mar 16 @ 12:48pm 
how do you start scavnege and stuff like that in single player? i cant figure it out, sorry if i missed something
Kamijou_Touma Mar 12 @ 11:14pm 
All right!!! The key re-function again!! Thanks Ziggy, I can happy play once again. Thanks a lot
Kamijou_Touma Mar 12 @ 11:06pm 
OK, Ziggy, I'll try the description. Thanks a lot. By the way, I only play off-line mode.
Ziggy  [author] Mar 11 @ 9:28pm 
Yeah, it's unfortunate. But they had no choice. Apparently there were online multiplayer servers that were using an exploit in the config files to do malicious things to people's games that wouldn't go away even after the player left the server. For that reason they needed to prevent config files from being loaded from within addons. Any changes to config files now need to be made manually by the player to ensure they are okay with those changes being made.
O'Nesix Mar 11 @ 9:10pm 
That's too bad, makes things more complicated for the modder and the person using the mod. Leave it to Valve to make things more difficult.
Ziggy  [author] Mar 11 @ 9:07pm 
There was a game update that broke certain things in certain addons. You need to follow the additional steps in the description to fix this. It will only take a couple minutes and the addon will be working again.
O'Nesix Mar 11 @ 8:52pm 
The function keys no longer work in-game as they did before.
Kamijou_Touma Mar 11 @ 8:18pm 
In fact, the function key -- from F1 to F8 appears to lose theirs function. Whenever I press in the game, it seems no use. The test map is lv4.
Kamijou_Touma Mar 11 @ 8:16pm 
help!! help!!, Unknown command: char_radial
Unknown command: diff_radial

i don't know how this happen, but it happened yesterday. I've checked my newly add mods which maybe have some conflict,but the answer is no.

Please help! Thanks!!

How do you install the source plugins and how do you use the binds?
Alex_D_Vasilkov Mar 4 @ 10:08am 
It is most fortunate that you still support the addon, and react quickly to Valve's patching of the game.
Kelpo Gaming Feb 27 @ 9:43am 
Hey, in the thing that you have to copy/paste to make the mod work, do I have to copy EVERYTHING, or just everything below the things that you can bind to whatever I want?
Ziggy  [author] Feb 27 @ 12:39am 
I've added some recommended SourceMod plugins to the description to raise awareness of it. SourceMod allows you to do a lot more with the game that workshop addons can't do. The plugins I've listed will further improve the bots significantly.

SourceMod works completely with single player games. It does take a bit of time to set up and edit all the config files to your liking, but it is well worth taking the time to do that!

There are a lot of other very useful SourceMod plugins as well. I've only linked the ones relating to bots.
Kaijuzilla Feb 25 @ 5:11pm 
OK thanks!
Ziggy  [author] Feb 25 @ 5:02pm 
Just follow the instructions in the description. Tells you exactly where the file is, how to get to it, and how to edit it.
Kedama! Feb 25 @ 1:16pm 
@TheBlueMan - Ziggy put the instructions on the description of this page at the top.
Kaijuzilla Feb 25 @ 1:03pm 
What folder/file should I add the text to? I'm not sure exactly what the config file is, and how to add the text in. Do I make a new file?
Kedama! Feb 25 @ 12:48pm 
Thanks for the update on how to remedy the new update that they put int. Did everything you said and it works jusdt as before. Thanks again!
Mustain11 Feb 24 @ 11:47pm 
Right, thanks a lot
Ziggy  [author] Feb 24 @ 3:21pm 
Open it with any text editor, such as Notepad.
Mustain11 Feb 24 @ 11:36am 
I'm sorry to sound thick, but how do I edit the file? It doesn't let me open it...
Ziggy  [author] Feb 24 @ 9:19am 
Using the radial menus will disable achievements.
xXRemXx | MonsterCat™ Feb 24 @ 8:15am 
Can we get achievements while using this mode?
