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.Contents
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.
Angles:
- Pitch Yaw Roll (Y Z X)
(angles)<angle> - This entity's orientation in the world. Pitch is rotation around the Y axis, yaw is the rotation around the Z axis, roll is the rotation around the X axis.
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.
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) (in all games since
)
Inputs
EnableDisableToggle- Active/deactivate the turret's mechanisms.
Bug: The Enable/Disable inputs have no effect while the turret is knocked over.DepleteAmmoRestoreAmmo- 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.
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> FireUser1toFireUser4- Fire the
OnUseroutputs; 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.
Outputs
OnDeployOnRetire- Turret has become active and dangerous or inactive and harmless.
OnTipped- Turret has been tipped over and is inactive.
OnPhysGunPickupOnPhysGunDrop- 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. OnKilled(only in
)- This output fires when the entity is killed and removed from the game.
