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.

To do: Any other games?

To do: Use templates to display which games include this entity.

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

Bug:  For , When you make the func_nav_blocker block the navigation squares touching it, you must send UnblockNav (Yes not intuitive) 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.

Keyvalues

Team(s) to block <choices>

Team(s) this entity should block

• -1 : Everyone
• 2 : Survivors, Terrorists
• 3 : Infected, Counter-Terrorists

Affects Flow? <boolean>

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

Targetname:

Name (targetname) <string>

The targetname that other entities refer to this entity by.

Entity Scripts (vscripts) <scriptlist> (in all games since )

Space delimited list of VScript files (without file extension) that are executed after all entities have spawned. The scripts are all executed in the same script scope, later ones overwriting any identical variables and functions.

Script think function (thinkfunction) <string> (in all games since )

Name of a function in this entity's script which will be called automatically every 100 milliseconds (ten times a second) for the duration of the script. It can be used to create timers or to simulate autonomous behavior. The return value (if present) will set the time until the next call.

Note:Try to avoid expensive operations in this function, as it may cause performance problems.

EnableDisable:

Start Disabled (StartDisabled) <boolean>

Stay dormant until activated (probably with the Enable input).

Note:This KeyValue is not available in Smart Edit and must be added manually.

Warning: Enabled/disabled state does not block or unblock NAV areas. Use BlockNav/UnblockNav

Recheck Breakables <Boolean>

Appears to respond to any changes to breakables even though a BlockNav/UnblockNav input is fire anyway from the breakable prop anyway.

Note:This KeyValue is not available in Smart Edit and must be added manually.

Inputs

BlockNav <string>

Starts blocking nav areas.

UnblockNav

Stops blocking nav areas.

Targetname:

Kill

Removes this entity from the world.

KillHierarchy

Removes this entity and its children from the world.

Note:Entities already remove orphaned children upon being removed, but this input removes all children on the same frame, being marginally faster than Kill.

AddOutput <string>

Adds a keyvalue/output to this entity. It can be potentially very dangerous, use with care.
KV Format: <key> <value>
I/O Format: <output name> <targetname>:<inputname>:<parameter>:<delay>:<max times to fire, -1 means infinite>

FireUser1 to FireUser4

Fire the OnUser outputs; see User Inputs and Outputs.

Use  !FGD

Same as a player invoking +use; may not do anything depending on the entity. Can also be invoked by firing an output that does not specify an input.

RunScriptFile <script> (in all games since )

Execute a VScript file from disk, without file extension. The script contents are merged with the script scope of the receiving entity.

RunScriptCode <string> (in all games since )

Execute a string of VScript source code in the scope of the entity receiving the input. String quotation may be needed when fired via console.

Bug: In , the code is executed in the script scope of the entity that fires the output, not the one receiving the input.

Warning: Never try to pass string parameters to a script function with this input. It will corrupt the VMF structure because of the nested quotation marks, which then must be removed manually with a text editor.

CallScriptFunction <string> (in all games since ) !FGD

Execute a VScript function in the scope of the receiving entity.

SetLocalOrigin <coordinates> (in all games since ) !FGD

Send this entity to a spot in the map. If the entity is parented to something, it will be offset from the parent by this amount.

SetLocalAngles <angles> (in all games since ) !FGD

Set this entity's angles.

EnableDisable:

Enable

Disable

Enable/disable this entity from performing its task. It might also disappear from view.

Warning: Enabled/disabled state does not block or unblock NAV areas.

Outputs

Targetname:

OnUser1 to OnUser4

These outputs each fire in response to the firing of the like-numbered FireUser1 to FireUser4 Input; see User Inputs and Outputs.

OnKilled  (only in )

This output fires when the entity is killed and removed from the game.
