This addon comes with 12 configuration files that are automatically created in the "left4dead2\ems\left4bots2\cfg" folder the first time you host the game with the addon enabled.
Don't be afraid of edit them to customize the addon the way you want.
If you fu** up something, simply delete the file or the entire "left4bots2\cfg" folder and let the addon recreate them with the default values.

There are over 160 settings in this file, each one with a default value you can change.
Here you can find more info on what the settings do:
https://github.com/smilz0/Left4Bots/blob/main/root/scripts/vscripts/left4bots_settings.nut
The settings can also be changed on the fly while you are in the game with the following commands:

• Via chat: !l4b settings [setting] [value]
  
• Via console: scripted_user_func l4b,settings,[setting],[value]

The convars are a sort of settings but they are handled by the game itself.
They are used to change some of the mechanics of the game or to alter some of the parameters of the vanilla AI.
Remember that the vanilla AI is still there, even with L4B2 ON. This addon only adds some features but the vanilla AI is still there most of the time.
In this file you can add your own improvement convars or delete the default ones you don't like.
For example, if you want the chapter to restart when the human survivors die (normal behavior), simply delete these lines from the file:
Here is the official list of the game convars:
https://developer.valvesoftware.com/wiki/List_of_Left_4_Dead_2_console_commands_and_variables

Many other AI improvement addons (like Competitive-Bots+) use the convars to improve the vanilla AI.
These addons are perfectly compatible with L4B2 but, if you want to make sure that L4B2 will not override the convar values of the other addon, you need to delete all the L4B2 convar changes in the convars.txt file.
However i suggest to keep this line: "sb_debug_apoproach_wait_time 0.5" as it defines how long the bots "dance" on the spot after executing a MOVE command from the addon. The default value is 5 and you probably don't want them to dance for so long. :D


This file maps the vocalizer lines to the L4B2 commands.
It looks like this:
The first is the vocalizer command (you can find them on google).
After the = comes the L4B2 command that you want to bind to that vocalizer line.
Here is the list of L4B2 commands:
https://github.com/smilz0/Left4Bots/blob/main/COMMANDS.md

Remember that the L4B2 commands come in 3 versions:

• bot command [parameter] (the bot to use for the command is selected automatically by the addon)
  
• bots command [parameter] (all the bots will execute the command)
  
• name_of_the_bot command [parameter] (you choose which bot to use by adding his name)

In the vocalizer.txt file you have to choose one from the first 2 versions of the command (bot or bots) and this is what is executed when you use the vocalizer line without selecting the bot first.
The 3rd version (with the bot name) is automatically used when you select the bot before the vocalizer line.

To cancel the previous commands you only need to use: bots cancel [parameter]. There is no "bot" version of that command but the version with the name of the bot is still used when you select the bot first.

You can remap the commands the way you want.
For example you can bind the "cancel" command to the "Let's go" and "Follow me" lines too, so you have more options to cancel the orders.
Then you can re-bind the "use" and "follow" orders to other vocalizer lines. You only have to find vocalizer lines that "sound" related to the commands so they are easier to remember, but even if they don't, they will still work so you can even bind the "use" command to the "Death Scream" vocalizer line if you want. :)


In L4B1 this was the list of items that you don't want the vanilla AI to pick-up.
In L4B2 this depends on the "items_not_to_avoid" setting.
If items_not_to_avoid is "0" then it's still the same logic.
If items_not_to_avoid is "1" (default) this file works in reverse logic, so the vanilla AI will only pick-up the items in this file and ignore all the others.
By default it works in reverse logic to allow the L4B2 weapon preference feature to work correctly.


This folder contains the weapon preference files for all the survivor characters.
Each character has his own preference file.
Each file has 5 lists on 5 different lines, one for each inventory slot:

1. Primary weapon
   
2. Secondary weapon
   
3. Throwable
   
4. Medkit
   
5. Pills

Each list defines the weapon priority from the highest to the lowest.
You can change the priorities as you like.
If you don't want the bot to pick-up a particular weapon, you simple remove the weapon from the list.
Grenade launcher, M60 and chainsaw no longer need you to install external addons like this:
https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=2634219419
As long as these weapons are in the list, the bot will be able to pick them up anyway.


You can easily change the VScript code of the addon.
