This article is about the point entity. For the brush entity, see func_door_rotating.

prop_door_rotating is a point entity available in all Source games. It creates an ordinary hinged door that can be opened by players and NPCs.

Note:(in all games since )(also in ) Rotating doors can be destructible if the model used was compiled with $collisiontext

Bug:Using raw door sound will cause the sound to play everywhere in the map, despite the distance. This can be ignored in singleplayer games, but may be a problem in multiplayer games, because all players will hear the door throughout the whole map. This can be fixed by using Soundscripts, or modifying the code of the prop_door_rotating entity if you create your own mod.  [todo tested in?]

Bug:Specifying a Custom Hinge Axis in Hammer is broken. Workaround is to modify the model, setting the origin to the hinge location.  [todo tested in?]

Bug: Firing a portal at a prop_door_rotating will cause the projectile to hang in midair in front of the player. Repeatedly doing this can cause extreme lag, and eventually lead to a crash. There is currently no known workaround for this.  [todo tested in?]

Warning:When making custom door props, add a door_options ↓ $keyvalue block, else every single door will throw an error about missing door_options. This won't cause any ill side effects, other than spamming the console with the same error multiple times.

Confirm:Determine and note if the bugs mentioned above are fixed in notable third-party games, mods, and engine branches (ex , , ).

Supported Models

Only specific models will work properly with this entity. They are:

• props_c17\door01_left.mdl
• props_c17\door02_double.mdl
• props_doors\door03_slotted_left.mdl
• props_c17\door03_left.mdl Half-Life 2: Episode One

Note:props_doors\door01_dynamic.mdl is not valid; it is meant for npc_furniture.

Most newer games have a model folder called "Props_Doors" where all doors are found, including static props that will not work for prop_door_rotating.
For a door model to be compatible, it must be a physics prop (Seen in Model broswers Info Tab) and the model origin must be on the hinge side of the door, because doors rotate around its origin.

Example of a compatible door (Green) and an incompatible door (Red)
Note the origin of the red door being in the bottom middle. That is where the door would rotate along.

Keyvalues

Name (targetname) <string>

The name that other entities refer to this entity by, via Inputs/Outputs or other keyvalues (e.g. parentname or target).
Also displayed in Hammer's 2D views and Entity Report.

See also:  Generic Keyvalues, Inputs and Outputs available to all entities

Slave name (slavename) <targetname>

Name of any door(s) that should open and close at the same time as this one. You could also give them all the same name.

Hardware Type (hardware) <choices>

The type of mechanism used to open the door (handle, push bar, keypad). The mechanism only appears in the game, not in Hammer.

• 0 - None
• 1 - Lever (i.e. door handle)
• 2 - Push bar
• 3 - Keypad
  Note: Keypad hardware only has a model in Half Life 2 EP1 & EP2. In other games it is used to change the lock and unlock door sounds.

Spawn Position (spawnpos) <choices>

State the door should begin in. Check the door's angles to see forward/backward orientation.

• 0 - Closed
• 1 - Open forward
• 2 - Open back
• 3 - Ajar

Ajar Angles (ajarangles) <angle>

If "Spawn Position" is "ajar", these are the angles to spawn at instead of being open or closed.

Hinge Axis (axis) <axis>

^[Todo]

Note:Despite Hinge Axis values, the door can only rotate on the Z Axis

Rotation Distance (distance) <float>

Number of degrees that the door should open, both forward and backward.

Speed (speed) <integer>

In degrees/second.

Fully Open Sound (soundopenoverride) <string>

Sound played when the door has finished opening.

Fully Closed Sound (soundcloseoverride) <string>

Sound played when the door has finished closing.

Moving Sound (soundmoveoverride) <string>

Sound played when the door starts to move.

Locked Sound (soundlockedoverride) <string>

Optional overrides to the sounds played by the door. Sound played when the player tries to open the door, and fails because it's locked.

Unlocked Sound (soundunlockedoverride) <string>

Optional overrides to the sounds played by the door. Sound played when the door is unlocked.

Delay Before close (returndelay) <integer>

Number of seconds the door waits until closing by itself. -1 means never auto-close.

Damage Inflicted When Blocked (dmg) <integer>

If an entity is blocking the door from moving, inflict this much damage per frame.

Can Damage Player (candamageplayer) <boolean> (only in )

If set, this door will kill the player blocking it. Used for the large blast doors in infra_c7_m2_bunker.

Note:This replaces the "Damage Inflicted When Blocked" keyvalue in INFRA .

Force Closed (forceclosed) <boolean>

If set, this door will close no matter what. Useful for doors that have to close even if the player tries to block them with objects.

Open Direction (opendir) <choices>

Force the door to open only forwards or only backwards. It will normally try to swing away from the entity that opened it, unless it is being blocked on the other side.

• Both directions
• Forward only
• Backward only

Pressure Delay (PressureDelay) <float> !FGD

Seconds to delay breaking from pressure. Allows creaking/groaning sounds to play.

Health (shoot open) (health) <integer> 

Deprecated.
In Quake and GoldSrc, if this was set, the door would open when it took this much damage. Nonfunctional in most Source games; can be emulated by parenting an invisible func_button with spawnflag 512 set, and having the button target this door.

Glow Distance (glowdist) <integer> (in all games since )

Default is 1024.

Todo: Same as L4D2's Glow Range?

A multiplier for the size of the model.

Tip:In Hammer++ with a prop selected in 3D view, hold Ctrl and scroll the mouse wheel to change the modelscale in increments of 0.5. Holding ⇧ Shift will scale it in smaller increments of 0.05.

Bodygroup (body / SetBodyGroup) <integer>

Some models have multiple submodels. This value selects from the index, starting with 0. May be overridden by animations and/or game code.

Note:If both body and SetBodyGroup are present (even if set to 0), body will be prioritized.

Lighting Origin (lightingorigin) <targetname>

Select an entity (not info_lighting!) from which to sample lighting instead of the entity's origin or $illumposition.

Shadow:

Disable Shadows (disableshadows) <boolean>

Prevents the entity from creating cheap render-to-texture shadows, or lightmap shadows if the entity is a prop_static. Does not affect shadow mapping.

Custom Door Models

1. Create ACT_IDLE, ACT_DOOR_LOCKED and ACT_DOOR_OPEN activities.
2. Add a door_options $keyvalues block:

$keyvalues
{
	prop_data
	{
		blocklos 1
	}
	door_options
	{
		default // Fallbacks if something is missing elsewhere
		{
			open	Doors.FullOpen1
			close	Doors.FullClose1
			move	Doors.Move1
			locked		DoorHandles.Locked1
			unlocked	DoorHandles.Unlocked1
		}
		hardware0 // First hardware type, by default a handle
		{
			locked		DoorSound.Null
			unlocked	DoorSound.Null
		}
		hardware1 // Push bar
		{
			locked		DoorHandles.Locked1
			unlocked	DoorHandles.Unlocked1
		}
		hardware2 // Keypad
		{
			locked		DoorHandles.Locked2
			unlocked	DoorHandles.Unlocked2
		}

		skin0  // Skin-specific sounds, including a custom surfaceprop.
		{
			open	Doors.FullOpen4
			close	Doors.FullClose4
			move	Doors.Move4
			surfaceprop	wood  // If no skin is specified, surfaceprop is always wood, no matter what's written elsewhere
		}
	}
}

L4D Series Doors

The Left 4 Dead series introduced a new set of doors that can be broken down by Infected.
Those new doors make use of $collisiontext and new "Pound" and "Damage" listings in door_options, highlighted below.
Some doors in L4D2, which were ported from L4D, also have the following activities, although they do not seem to work: ACT_DOOR_ANIMTOLOCK, ACT_DOOR_ANIMTOUNLOCK, ACT_DOOR_OPENFAIL.

Note:Animations with the activity ACT_DOOR_LOCKED do not seem to work. Only workaround seems to be manually adding I/O connections to the door in hammer, or play a specific sequence when used while locked.

$collisiontext
{
	break 
	{
		"model"		"Props_downtown\door_interior_128_01_dm01_02" //Spawns a debris model.
		"health"		"100"
		"fadetime"		"10"
	}
}

$keyvalues
{
	prop_data 
	{
		"base"			"Door.Standard"
		"allowstatic"	"1"
		"blocklos"		"1"
		"dmg.bullets"	"0"  //Bullets will no longer damage this door. In L4D2 this is only used on the last damage model.

	}
	door_options 
	{
		"defaults"		 
		{
			"open"			"Doors.FullOpen1"
			"close"			"Doors.FullClose1"
			"move"			"Doors.Move1"
			"locked"		"DoorHandles.Locked1"
			"unlocked"		"DoorHandles.Unlocked1"

			"pound"			"Doors.Wood.Pound1"								//Sound that plays when infected attack the door to break it down.
			"surfaceprop"	"wood"											//Overwrites Surfaceprop.
			"damage1"		"props_downtown\door_interior_128_01_DM01_01"	//What the first damage model is.
			"damage2"		"props_downtown\door_interior_128_01_DM02_01" 	//What the second damage model is.
			"damage3"		"props_downtown\door_interior_128_01_DM03_01" 	//What the third damage model is.
		}
	}
}

The "Damage1", "Damage2" and "Damage3" lines determine what models will be used for the broken stages of this door model.

Warning:All damage models need their own set of door options. Not having door options for the damaged models will cause those doors to be silent if you decide to immediately use a damaged door.
