I'm making sure one of my maps has sentry placements in-case anyone wants to play offline. I have the bot hint entities: bot_hint_sentrygun and bot_hint_engineer_nest in places I think a sentry would do well in. I also setup a trigger brush tied to func_tfbot_hint as sentry gun spot hint. The origin is at the center of the field so that an engineer can come down from the base and place a sentry and the sentry would always face the enemy team. I then compile and generate navigation mesh for the map. I then use this command "tf_bot_add 1 engineer" to spawn one engineer. He stays still in spawn for about 10 seconds then walks towards the objective and doesn't setup a sentry. I know sentry gun hints are just preferred places for engineers to setup a sentry but do I need to do anything? Or will they place down a sentry just under specific circumstances?
