npc_turret_floor

 npc_turret_floor is a point entity available in the Half-Life 2 series.

It is unstable and falls over easily, but cannot be destroyed. It scans a 90 degree area, and will lock on to and fire at a target until that target goes is out of range or can't be seen.

When knocked over, the turret will fire randomly for a few seconds then disable (much like the floor turret from Portal). However, unlike the Portal turret, it will switch on again after being placed upright.

 Placement Tip: If used in combat situations, this npc can add variety to a firefight and upgrade an enemy force's fire power

Bug: With source 2006 can be such situations when you move some npc using scripted sequence and you place turret enough close to this sequence, this can cause npc to nodes teleporting bug, for example with npc_alyx, just remove it near your npc pathway or change a location of your scene.

Note:Some keyvalues, flags, inputs, or outputs might not affect an NPC, based on the functionality and coding of the NPC.

Keyvalues

Model <model path> !FGD

Overrides the normal Combine Floor Turret model

Skin Number <int>

Which skin to use for this turret. Set to 0 to select randomly.

The targetname that other entities refer to this entity by.

Entity Scripts (vscripts) <scriptlist> (New with Left 4 Dead 2)

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> (New with Left 4 Dead 2)

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.

Flags

• Autostart

Bug: not armed npc_citizen will react and run away from turret even if they are forced to use neutral relationships with it what can ruin ai_goal_actbusy activity for example, disabling this flag can help in this cases.

• Start Inactive
• Fast Retire
• Out of Ammo
• Citizen modified (Friendly) (New with Half-Life 2: Episode Two / Source 2007)

Inputs

Enable

Disable

Toggle

Active/deactivate the turret's mechanisms.

Bug: The Enable/Disable inputs have no effect while the turret is knocked over.

DepleteAmmo

RestoreAmmo

Depletes ammo from a turret, causing it to dry-fire, or restores ammo. Turrets never run out on their own.

Bug: The DepleteAmmo/RestoreAmmo inputs have no effect on Portal turrets.

SelfDestruct  (New with Half-Life 2: Episode Two / Source 2007)

Emit a warning then self-destruct in a small explosion.

Targetname:

Kill

Removes this entity and any entities parented to it from the world.

KillHierarchy

Functions the same as Kill, although this entity and any entities parented to it are killed on the same frame, being marginally faster than Kill.

AddOutput <string>

Evaluates a keyvalue/output on this entity. It can be potentially very dangerous, use with care.
Format: <key> <value>
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. Can also be invoked by creating an output that does not specify an input.
This input is not included in Valve's FGDs.

RunScriptFile <script> (New with Left 4 Dead 2)

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

RunScriptCode <string> (New with Left 4 Dead 2)

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> (New with Left 4 Dead 2) !FGD

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

SetLocalOrigin <coordinates> (New with Alien Swarm) !FGD
