script_nav_blocker is a point entity available in Left 4 Dead 2. Its a func_nav_blocker, readjusted for vscripts by being stripped of any unnecessary brush data. Other than that, what applies to func_nav_blocker is applicable to script_nav_blocker. Since its a brush entity technically, using the keyvaluesminsandmaxsstill works.

When compiling Entity Groups, func_nav_blocker entities are converted to script_nav_blocker.

Bounding Box Extents (extent) <vector>

Controls the size of the bounding box. If mins/maxs were usable here instead then mins -100 -100 -100 and maxs 100 100 100 would be equivalent to extent 100 100 100.

Origin (origin) <vector>

Center of the bounding box specified by the extent

Angles (angles) <vector>

Angles of the bounding box specified by the extent

Tip:Using angles other than 0 0 0 is pointless. AABB is used to block nav areas

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

Team this entity should block.

• -1 : Everyone
• 2 : Survivors
• 3 : Infected

Affects Flow? (affectsFlow) <boolean>

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

Important:If this is true, don't block the only path to the level's goal with it, otherwise the flow won't be computed properly.

Inputs

BlockNav

Starts blocking nav areas.

UnblockNav

Stops blocking nav areas.
