CFuncNavBlocker

Code classes:

• CFuncNavBlocker
• CBaseEntity (all ents)

CFuncNavBlocker is a code class in all Source games except .

Classnames:

• func_nav_blocker - A brush entity that can block navmesh areas touching it so that bots will not attempt to go somewhere.

Important: The entity will not start to block automatically; it must first be activated with the BlockNav input.

Bug: In , when you make the func_nav_blocker block the navigation squares touching it, you must send UnblockNav along with BlockNav, if the blocker resides on the same navigation square(s) as a prop_door_rotating or func_physbox and perhaps other entities. Failure to do so will create the console error Area ### already blocked by a different team id. May produce flow bugs (and flow bugs do happen). The navigation square numbers can be seen in-game by pointing at the nav square with z_debug 1 and nav_edit 1.

Bug: Seems to not work in .

Note: func_nav_blockers that are compiled into entity groups are converted to the entity script_nav_blocker.
