Description:

As a request from Dr. Lightmare here, this plugin allows the AI to grab and use ammo packs in situations that can be configured:

1. Their primary weapons have low ammunition. (This also applies to Tier 3 weapons and hidden CS:S weapons as well.)
2. During a tank's spawn.
3. During a witch's spawn.
4. During a mob's spawn.

ConVars:

• "ammo_pack_deployers-l4d2_version" - "1.11" (Version of this plugin)
• "apd-l4d2_low_ammo" - "1" (Enable/Disable check for low ammunition)
• "apd-l4d2_tank_spawns" - "1" (Enable/Disable check for tank spawns)
• "apd-l4d2_witch_spawns" - "1" (Enable/Disable check for witch spawns)
• "apd-l4d2_mob_spawns" - "1" (Enable/Disable check for mob spawns)
• "apd-l4d2_min_ammo_smgs" - "15" (Minimum ammunition required for SMG ammo checks)
• "apd-l4d2_min_ammo_t1shotguns" - "10" (Minimum ammunition required for Tier 1 Shotgun ammo checks)
• "apd-l4d2_min_ammo_rifles" - "25" (Minimum ammunition required for Rifle ammo checks)
• "apd-l4d2_min_ammo_t2shotguns" - "10" (Minimum ammunition required for Tier 2 Shotgun ammo checks)
• "apd-l4d2_min_ammo_snipers" - "20" (Minimum ammunition required for Sniper ammo checks)
• "apd-l4d2_min_ammo_m60s" - "30" (Minimum ammunition required for M60 ammo checks)
• "apd-l4d2_min_ammo_launchers" - "5" (Minimum ammunition required for Grenade Launcher ammo checks)

Commands:

Blank.

Bugs:

1. [FIXED] Error "Invalid Handle 0" pops up every time the plugin activates.

Notes:

1. Don't panic if you don't want to install Left 4 Downtown 2 extension. This plugin already has a back-up plan which is mostly hooking events to make checks there.
2. Don't worry about not installing Left 4 Downtown 2 extension this time. You can substitute the "bots grabbing ammo packs" method with the Gear Transfer plugin instead. Just don't forget to not let the bots pass the ammo packs so they can use it.

Changelog:

02-03-2018:
X First release.

06-28-2018:
X (Probably) Final release.
+ Fixed incorrect low ammo check.
+ Added exception for bots reviving other players.
+ Added delay for deploying ammo packs in case it fails.
+ Balanced the priority of medkits and ammo packs when bots try to pick either one up.
+ "Invalid Handle 0" error should no longer spam when the plugin starts to operate.

This is a very useful plugin, Thank you cravenge. I am wondering about these errors that are appearing in my logs, should I be worried or are these harmless?

You're not checking whether it is a valid entity:

public void OnEntityCreated(int entity, const char[] classname)
{
	if (entity < 1 || entity > 2048)
	{
		return;
[...]

vs

public void OnEntityDestroyed(int entity)
{
	if (IsAmmoPack(entity) && !IsAmmoPackOwned(entity))
	{
[...]

Adding some check in OnEntityDestroyed before blindly using "entity" might fix it.

Ohh, okay. Noted! Thanks!
