Spawn survivor bots with a command. Takes advantage of the info_l4d1_survivor_spawn entity, and adds a public native for other plugins to use.
Warning: some plugins may not detect the bots when they spawn due to being on a different team.

Use the first letter of a survivor name or the m_survivorCharacter numbers to choose who the bots spawn as.
If used by a player admin, the bot will spawn in their location.
If used in the server console, the bot will spawn in the first connected player's location.
The native will only accept m_survivorCharacter numbers, and requires a vector location to be provided to spawn at.

Uses Silvers' method to spawn the bots, found in the Survivor Bot Holdout plugin.


Side Note
The bots will act like they've been rescued if you spawn them after a survivor has already left the saferoom. They'll fire the survivor_rescued event and say thanks as if rescued.
This only applies if you spawn them on the main Survivor team.


Examples of sm_survbot use:

Spoiler

!survbot n
^ Spawns a Nick bot.
/survbot z 4
^ Spawns a Zoey bot on The Passing team. Having a Zoey on the main Survivor team will crash Windows servers unless you have this plugin. Zoey is now fixed by Valve. Surprising.
sm_survbot 1
^ Spawns a Rochelle bot using the numeric m_survivorCharacter order.
sm_survbot -1
^ Spawns a bot with random character.
sm_survbot francis
^ Spawns a Francis bot.
sm_survbot fuck
^ Spawns a Francis bot. I hate swear words.
survbot command requires the CHEATs admin flag.

-= Releases =-

Version 1.0.4
- Fixed bug where Bills provided by the L4D1 campaigns by default (Bill with m_survivorCharacter 0) would just be teleported on attempt to spawn survivor bots.
- Added include file with a public native for other plugins:
  * l4d2_spawnSurvBotsHack.inc in scripting/include
  Contains L4D2_CreateSurvivorBot_Hack(const float origin[3], int character = -1, int team = 2, int survSet = SURVBOTS_L4D2)
- Changed plugin name from l4d2_spawn_surv_bots.smx to l4d2_spawnSurvBotsHack.smx
- Changed sourcemod/cfg config file name from spawn_surv_bots.cfg to l4d2_spawnSurvBotsHack.cfg
- Added l4d2_spawnBots_nativeTest.sp in sourcemod/scripting to demonstrate native use.
- Converted to zip file attachment.
- [Version 1.0.4b] Removed accidental debug PrintToServer in native function.
Version 1.0.1c
- Small optimization of valid player checks.
- Fixed potential temp-bot kicking fail issue.
Version 1.0.1b
- Stopped using static for variables that should not persist in attempt to fix a bug with always-Bill bots.
Version 1.0.1
- Optimized ConVar value grabbing with Silvers' code.
- Now compiles for Sourcemod 1.11.
Version 1.0.0
- Initial release.

-= ConVars =-

sm_spawn_survbot_temp 0 - min:0/max:1
^ Kick the Command-spawned bots as soon as they die.
May be buggy.

-= How to install =-
Extract the .ZIP's contents and move the folders into <Your L4D2 Game/Server Installation>\left4dead2
Example:
Left 4 Dead 2\left4dead2 (Game)
l4d2ds\left4dead2 (my Dedicated Server)
Make sure to remove l4d2_spawn_surv_bots.smx as that is an older, incompatible version of the plugin!

Nice thanks!

You can set the bots name using "SetClientName()". I'm guessing you tried this with "targetname"?

I didn't know about SetClientName() or maybe I forgot about it, but thanks!

Oh yeah, the DispatchKeyValue(spawn, "targetname", TRICKERY_SPAWNBOT_NAME) line.
No, I didn't use that to try and set the client name, I tried to use that to... actually I don't remember what I tried to do, but I think it was just a test. My brain is french fry.

cripes i forgot to credit you for the code used in this plugin

[Silvers]

btw to support compiling on 1.11 you need to change:

PHP Code:

const float[3] origin, const float[3] angles 


to:

PHP Code:

const float origin[3], const float angles[3]

Ohh... At first I wasn't sure about those being backwards-compatible with 1.8, but it looks like 1.10 and 1.8 handle it just fine.
I was never aware that const float[3] origin wasn't recommended for future versions.
I've found a few other errors with the 1.11 compiler now, so after a few tweaks it should work with 1.11 now.

Can you add sm_cvar with item give to bot when add bot? Weapon , healt , bom
and add a notification line when creating a bot successfully like this plugin https://forums.alliedmods.net/showthread.php?p=1446781

A good plugin is the only one that works.
But there is a big problem, bots are not visible in the list of server players and I have 0 slots out of 32. Does anyone have a solution to this problem? It is necessary for the bots to be like real players and display in slots so that people enter the server

[guyguyga]

If the bot is spawned on the passing team, will they follow the main team or will they just hold out where they are?

Can't help you with that. Faking player count is against the rules of Valve's server browsers.

They will just hold out if sb_l4d1_survivor_behavior is 1 when they are spawned.
Depending on the nav mesh of the map, they will stand still in the place they spawned in if there's no BATTLESTATION nav squares, or they will run to one of the BATTLESTATION nav squares and hold out on them.
They will then rotate between the BATTLESTATION nav squares if there is one that's available and not taken by an existing Passing bot.
This is more-or-less the same behavior used in The Passing.

Otherwise if spawned when sb_l4d1_survivor_behavior is 0 they will re-use the normal survivor bot behavior, but because the bots are technically on a different team, they won't care about normal survivors.
