A few questions

[Pacman1105]

Not really an issue (github mobile wouldn't let me comment anywhere else so I have to make an issue) but I have a few questions.

Mainly, how would one go about implementing this into Half-Life single player? If possible at all (most likely not considering how AFAIK these don't target NPCs or have player following).

Secondly, how would I add support for a custom mod's weapons?

Lastly, would there be a different bot plugin or sdk addition (built into the Half-Life code) that would be better for my use case?

Well I've not tested those in HL1 SP before but we've removed RCBot MM Sven Co-op that had the code supported for that similiar gameplay but with online players.

The bots_weapons.ini is used to add custom weapons but you need to make sure you know the Mod ID and Weapon ID numbers etc in order to use it.

And well there's not many other bot addons that are updated and reliable enough to work for GoldSrc engines apart from TFC, CS 1.6, DoD and more. But recently I've been adding support for S&I, AHL, WizWars and HL: Arena.

it'd probably be possible to add/port bots directly into the HL1 code (as a separate entity from the player) to make them usable in single player, however that'd probably be quite complicated (considering how player related code is spread throughout a lot of files, and the game might not like having multiple "clients" in a singleplayer game (I'll look into it sometime within the next decade)
