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.

SAFEST_ROUTE:
- Applies a 0x-to-4x multiplier to the path cost of nav areas based on recent, nearby combat (within 1000 HU during the last 30 seconds).
- Applies a 5x multiplier to the path cost of nav areas that are within range and line-of-sight to an enemy sentry.

RETREAT_ROUTE:
- No special path cost modifiers.


NOTE: This is not a complete list of TFBot actions; actions that don't do any pathing aren't included in this document.
