Func nav blocker

Available in . It is a brush entity that can block nav areas touching its AABB used to restrict NPCs from crossing over nav areas.

Todo: Any other games?

Todo: Use templates to display which games include this entity. (But how would we accomplish this?)

Note:The entity will NOT start to block automatically: it must first be activated with the BlockNav input.

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

Keyvalues

Team(s) to block (teamToBlock) <choices>

Team this entity should block.

• -1 : Everyone
  Warning: for everyone either edit FGD and use value -2 or turn off smart edit and set that, -1 is not valid and the nav blocker will not work
• 2 : Red , Survivors , Terrorists
• 3 : Blue , Infected , Counter-Terrorists

Note: teamToBlock non-functional, always blocks either for both teams or for no team.

Affects Flow? (affectsFlow) <boolean> (only in )

Does this Nav Blocker block flow in the level? Only Nav Blocker with this enabled will cause flow recomputation on blocking/unblocking.

Important:When this is true don't block the only path to the level's goal with it or the flow won't be computed properly

Inputs

BlockNav

Starts blocking nav areas.

UnblockNav

Stops blocking nav areas.
