Func lookdoor

Template:Hl2 brush It's a door that moves, either when looked by a targeted object or when a target object comes near the door. Behavior can be either based on viewing direction or proximity alone, or on a combination of both.

Note:The SetPosition input and Start Position keyvalue do not perform any bounds checking, so values less than 0 and greater than 1 can be used. Negative values will move in the opposite direction to the movement direction, and values greater than 1 will move it in multiples of the set Move Distance. Moving past the opened/closed position does not trigger the OnFullyOpen and OnFullyClosed outputs.

Bug:There are bugs that may arise when parenting this entity to any of these: func_movelinear, func_lookdoor, func_water_analog. A func_door (or for func_water_analog, func_water) can be used as a workaround. (see here for a code fix)^{[ Code Fix]}

Confirm:Might be fixed in Portal 2? Parented movelinears are used extensively for this game's piston platforms.

In code, it is represented by theCLookDoorclass, defined in thelook_door.cppfile.

Keyvalues

Target (target) ([todo internal name (i)]) <targetname> !FGD

View cone switch for this door (Necessary to trigger it).^[Clarify]

Proximity Distance (ProximityDistance) ([todo internal name (i)]) <float>

If non-zero, how close player must be for door to move.

Proximity Offset (ProximityOffset) ([todo internal name (i)]) <float>

Offset from the target object.

Field of View (FieldOfView) ([todo internal name (i)]) <float>

If non-zero, how far away from the door the player can look while still triggering it.

FuncMoveLinear:

Move Direction (Pitch Yaw Roll) (movedir) <angle>

The direction the entity will move in.

Start Position (startposition) <float>

Position of brush when spawned, where 0 is the starting position and 1 is starting position + (move direction * move distance).

Speed (speed) <integer>

The speed that the brush moves, in inches per second.

Move Distance (movedistance) <float>

The distance from the starting point that the brush should move, in inches.

Block Damage (blockdamage) <float>

The amount of damage to do to any entity that blocks the brushes, per frame.

Bug:Block damage doesn't function on players who passed through a trigger_teleport using noclip, though it will have effect again if the the player goes through a trigger_teleport without noclip.  [todo tested in ?]

Sound played when the brush starts moving. (startsound) <sound>

The sound to play when the brush starts moving.

Sound played when the brush stops moving. (stopsound) <sound>

The sound to play when the brush stops moving.

Inputs

InvertOn

Make the door behave oppositely. Player has to be outside Proximity Distance, and not looking at the door within Field of View.

InvertOff

Turn door behavior back to the normal method.

FuncMoveLinear:

Open

Move the brush to the end position (starting position + (move direction * move distance)).

Close

Move the brush to the starting position.

SetPosition <floatRedirectInput/float>

Move the brush to a specific position, where 0 is the starting position and 1 is the starting position + (move direction * move distance).

SetSpeed <floatRedirectInput/float>

Set the speed and update immediately.

TeleportToTarget <targetnameRedirectInput/string> (only in )

Teleport to the origin of a given entity.

ResetPosition <floatRedirectInput/float> (only in )

Set a new start position, parameter relative to wherever the current one is.

Todo: Parameter might actually be optional?

Outputs

FuncMoveLinear:

OnFullyOpen

!activator = !caller = this entity
Fired when the brush reaches the end position (starting position + (move direction * move distance)).

OnFullyClosed

!activator = !caller = this entity
Fired when the brush reaches the starting position.
