Bots:

  • TFBots now treat certain weapon attacks as "quiet" (Spy knife, cloaking/uncloaking, some melee weapons, fists, etc). "Quiet" weapons can only be heard by TFBots when nearby, and their chance of being noticed is halved if the environment is "noisy" (ie., lots of non-quiet gunfire going on in the area). This greatly improves Spies ability to backstab TFBots without the entire team immediately turning on them.

    • Spy bots lead their target's position as they chase them down for a backstab now
    • Spy bots don't go after victims until setup time has elapsed
    • Hard and Expert Spy bots avoid looking at their prey until they get close and go for the stab
    • Easy Spy bots don't avoid enemies, or try to get behind before stabbing
    • Normal Spy bots don't avoid enemies
    • Fixed bug where Spy bots would jump against the enemy spawn gates during setup time
  • Medic bot improvements:
    • Medic bots stick much closer to running patients now
    • Medic bots stick much closer to their patient if they have an Ubercharge ready, or are deploying their Uber
    • Medic bots hide from Sentryguns now, too
  • Pyro bot improvements:
    • Pyro bots are less "pushy" with their compression blast, but will use it against Ubers and to get enemies off of a capture point

Other:
  • Razer Hydra support can be enabled via "sixense_enabled 1" in the console. See http://sixense.com/tf2 for details.
