Team Fortress 2 obj_sentrygun is a point entity available in Team Fortress 2 .

Entity description

Used to place a sentry gun in your map. The sentry gun it creates is the same as a normal one erected by an engineer in-game that can be repaired, damaged, and upgraded depending on it's flag settings. There are currently no options in the obj_sentygun settings to prevent it from being sapped by spies.



Name (targetname) <string>
The targetname that other entities refer to this entity by.
Entity Scripts (vscripts) <scriptlist> (in all games since 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> (in all games since 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.png Note: Try to avoid expensive operations in this function, as it may cause performance problems.


Parent (parentname) <targetname>
Specifies a movement parent. An entity will maintain its initial offset from its parent. An attachment point can be added to the end of the name, separated by a comma.


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.


Team <choices>
  • 2 : Red
  • 3 : Blue
Starting Upgrade Level <choices>
Object spawns in the selected level.
  • 0 : Level 1
  • 1 : Level 2
  • 2 : Level 3
Note.png Note: Values higher than 2 are accepted (need to be typed in with SmartEdit off), with the limit being 90. With higher levels, the objects gain more health/damage/recharge speed.
SolidToPlayer <choices>
Object is solid or non-solid to players. !FGD
  • 1 : Solid
  • 0 : Non-solid


  • 2 : Invulnerable
  • 4 : Upgradable
  • 8 : Infinite Ammo



Removes this entity from the world.
Removes this entity and its children from the world.
Note.png 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 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> (in all games since 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.png Bug: In Left 4 Dead 2, the code is executed in the script scope of the entity that fires the output, not the one receiving the input.
Warning.png 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 Left 4 Dead 2) !FGD
Execute a VScript function in the scope of the receiving entity.
SetLocalOrigin <coordinates> (in all games since Alien Swarm) !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 Alien Swarm) !FGD
Set this entity's angles.


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.
Removes this entity from the the movement hierarchy, leaving it free to move independently.

Template:I Angles


SetHealth <integer>
Sets the current and maximum health. If the object is upgraded, the health will scale according to the new value.
Bug.png Bug: Crashes if set to 0.
AddHealth <integer>
Increase the current health of the object. Does not surpass maximum health. Does not destroy the building if set at 0.
RemoveHealth <integer>
Decrease current health of the object. Destroys the object if the health hits 0.
SetSolidToPlayer <boolean>
Sets the object to be solid or non-solid to players. 0 - non-solid, 1 - solid. !FGD
Note.png Note: The builder of the building will always be solid to the object.
SetTeam <integer>
Ses the team the object is allied to. Does not change skin.
Skin <integer>
Sets the skin the object uses. Useful in conjunction with SetTeam.
Sets the builder of the object to the !activator.
Makes the building visible and re-enables it.
Makes the building invisible and disables it.
Bug.png Bug: Does not hide the obj_dispenser screen. A workaround is to fire the SetInactive (or SetActive) on the vgui_screen entity, although it will apply to all buildings.
Enable the object.
Note.png Note: Using Enable after using the Hide input will enable the building and keep it invisible.
Bug.png Bug: Enable will reset the upgrade level on the object. Use the Show input instead, which properly re-enables the object.
Disable the object.



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 Left 4 Dead Left 4 Dead 2)
