This wall-of-text will describe how Mannhattan gatebots work, and then based on that, the reason why bots with special AI (e.g. sentry busters, engie bots) that walk near the gate areas do weird things.

Part 1: func_nav_prerequisite

There's a type of map entity called func_nav_prerequisite, which is integral to how gatebots work. You can put one of these entities in a particular portion of a map, and it will make bots stop what they're doing and do something else before they proceed. (They're only a "prerequisite" in the sense that a bot who walks through one is commanded to do something else before it can proceed with what it was doing before.) There are three possible things a func_nav_prerequisite can be set to make bots do:

• Destroy entity. In theory, this would make bots switch to the CTFBotNavEntDestroyEntity AI action, but the (apparently working) code for it was never actually hooked up for whatever reason. The map designer specifies which entity the bo

TF projectile class hierarchy as of 20161025a
(reverse engineering by sigsegv)


Each projectile class has a 'yes' or 'no' after it to show whether it IsDeflectable() by airblast.
A capitalized YES/NO means that the class specifically overrides IsDeflectable().
A non-capitalized yes/no means that the class inherits IsDeflectable() from a parent class.

TFBot Path Cost: Route Types by Action


DEFAULT_ROUTE:
- In MvM, non-MiniBoss bots get a large random factor applied to their path cost to make them spread out more randomly.

FASTEST_ROUTE:
- No special path cost modifiers.
