Tf bot

 tf_bot is a point entity available in Team Fortress 2.

In code, it is represented by theCTFBotclass, defined in thetf_bot.cppfile.

Entity Description

A NextBot entity for TF2 that acts as a player. They are used for bots in Team Fortress 2, which are mainly used in the Training and Mann Vs. Machine gamemodes, and are created automatically by the game when creating a listenserver through the training option. This entity can be created through tf_bot_add, which when used will randomly select a bot name out of a hardcoded list of bot names.

Bug:Creating the entity through ent_create will crash the game.  [todo tested in ?]

Bug:This entity will not move in Capture The Flag (and by proxy MvM) if there is no flag for that entity's team.  [todo tested in ?]
