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 120 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
Note:Some keyvalues, flags, inputs, or outputs might not affect an NPC, based on the functionality and coding of the NPC.Contents

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(in all games since)- Emit a warning then self-destruct in a small explosion.
Base:
AddContext<string>- Adds to the entity's list of response contexts. See Context.
AddOutput<string>- Assigns a new keyvalue/output on this entity. For keyvalues, some rely on extra necessary code to be ran and won't work if its simply just changed through this input. There is a strict format that must be followed:
// Format of changing KeyValues: "AddOutput [key] [value]"
//// Raw text:
"OnUser1" "!self,AddOutput,targetname new_name"
// Format of adding an Output: "AddOutput {targetname}:{inputname}:{parameter}:{delay}:{max times to fire, -1 means infinite}"
//// Raw text:
"OnUser1" "!self,AddOutput,OnUser1:SetParent:!activator:0.0:-1"
// Arguments can be left blank, but the empty blank should still be contained.
//// Raw text:
"OnUser1" "!self,AddOutput,OnUser1:ClearParent::0.0:-1"
|
ClearContext- Removes all contexts from this entity's list.
ClearParent- Removes this entity from the the movement hierarchy, leaving it free to move independently.
FireUser1toFireUser4- Fires the respective
OnUseroutputs; see User Inputs and Outputs.
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 thanKillinput.
RemoveContext<string>- Remove a context from this entity's list. The name should match the key of an existing context.
SetParent<string>- Move with this entity. See Entity Hierarchy (parenting).
SetParentAttachment<string>- Change this entity to attach to a specific attachment point on its parent. The entity will teleport so that the position of its root bone matches that of the attachment. Entities must be parented before being sent this input.
SetParentAttachmentMaintainOffset<string>- As above, but without teleporting. The entity retains its position relative to the attachment at the time of the input being received.
DispatchResponse<string> !FGD- Dispatches a response to the entity. See Response and Concept.
DispatchEffect<string> (removed since
) !FGD- Dispatches a special effect from the entity's origin; see also List of Client Effects. Replaced by the particle system since .
RunScriptFile<script> (in all games since
) (also in 
)- 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) (also in )- 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 Hammer, using string arguments will corrupt the VMF file's structure, making the file unviewable for the next Hammer session.Fix:Remove the string argument manually with a text editor.Note: Backtick characters ` are replaced with quotation marks at runtime, allowing quotation marks to be used when normally not possible.
CallScriptFunction<string> (in all games since) (also in ) !FGD- Calls a VScript function defined in the scope of the receiving entity.
TerminateScriptScope(only in) !FGD- Destroys the script scope of the receving 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.
Outputs
OnDeploy
OnRetire- Turret has become active and dangerous or inactive and harmless.
OnTipped- Turret has been tipped over and is inactive.
OnPhysGunPickup
OnPhysGunDrop- Picked up/released by Gravity Gun or +use.
Targetname:
OnUser1toOnUser4- These outputs each fire in response to the firing of the like-numbered
FireUser1toFireUser4Input; see User Inputs and Outputs.
