This entity is not in the FGD by default.
See below for instructions on making it available.

This entity is Obsolete. Its use is discouraged, and it may only exist/function in older engine branches.
It has since been replaced by func_water_analog. Non-moving water brushes should be part of worldspawn.

func_water is a brush entity available in all Source games. Legacy entity from the GoldSrc engine, deprecated by func_water_analog. It is still used in some Half-Life: Source maps.

Important:Does not work with materials using real time reflections and/or refractions, as seen in Water and Refract.
Use a material which uses a regular brush shader, such as:

• nature/water_movingplane.vmt (LightmappedGeneric)
• nature/water_dx70.vmt (LightmappedGeneric)
• nature/hazard_liquid.vmt (LightmappedGeneric) (only in )
• liquids/!greenslime.vmt (UnlitTwoTexture) (only in )

Bug:This entity always has its contents set to CONTENTS_WATER (regardless of brush contents), with no way of setting its contents to CONTENTS_SLIME. In most games, this will only affect splash particles.

Code Fix:Add a KV that is read by CBaseDoor::CreateVPhysics to set fluid.contents (defaulting to CONTENTS_WATER if KV is absent)

  (tested in: SDK 2013 source code)

Code:Both func_water and func_door are linked to CBaseDoor C++ class. The game code checks the classname KV to distinguish between them, applying specific behaviors if the classname is "func_water". As such, using AddOutput to change the classname of a func_water may have unexpected effects.

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

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

The direction the water will move when it is told to 'Open'. Default value is "0 0 0".

Wave Height (WaveHeight) <string> 

Deprecated.
Default value is 3.0. No effect on stock shaders, as GoldSrc-style waves were removed in Retail Half-Life 2 (only existing in the leaked "beta").

BaseDoor:

Linked Door (chainstodoor) <targetname> !FGD

Passes the door's +use inputs and touch events onto a different door, so it also is activated.

Block Filter Name (filtername) <targetname>

(For Half-Life: Source) Filter to use to determine entities that can block the door.

Speed (speed) <float>

Speed that the door moves, in units (sliding door) or degrees (rotating door) per second.

Start Sound (noise1) <sound>

Sound to play when the door starts opening. Also plays when door starts closing if startclosesound is absent.

Stop Sound (noise2) <sound>

Sound to play when the door stops opening. Also plays when door stops closing if closesound is absent.

Start Close Sound (startclosesound) <sound>

Sound to play when the door starts closing.

Stop Close Sound (closesound) <sound>

Sound to play when the door stops closing.

Delay Before Reset (wait) <float>

Time until the door returns to the closed position. A value of -1 means the door never auto-closes.

Lip (lip) <float>

When the door opens, it will move its full length minus this many units. Negative values will make the door move that many more than its length.

Blocking Damage (dmg) <float>

Amount of damage done to entities that block the movement of this door, per frame.

Bug:Normally a door will damage things blocking it, however if the player is teleported by a trigger_teleport while using noclip, they will not be damaged.  [todo tested in?]

Force Closed (forceclosed) <boolean>

Makes the door close no matter what. Useful for doors that have to close even if the player tries to block them with objects.

Ignore Debris (ignoredebris) <boolean>

Changes the door's collision group to COLLISION_GROUP_INTERACTIVE, which ignores debris objects. Not compatible with the Non-solid to Player spawnflag as it also sets a collision group.

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.

Message If Triggered (message) <string> 

Deprecated.
In Quake and GoldSrc, if this was set, a message would appear on the the player's hud when the door is locked and they attempt to open the door. Nonfunctional in most Source games; can be emulated by calling an env_message with the door's OnLockedUse output.

Locked Sound (locked_sound) <sound>

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

Unlocked Sound (unlocked_sound) <sound>

Sound played when door is unlocked.

Spawn Position (spawnpos) <choices>

State the door should begin in.

• 0: Closed
• 1: Open

Locked Sentence (locked_sentence) <choices> (only in )

Intercom voiceline for when the player tries to use the door, but it's locked.

Unlocked Sentence (unlocked_sentence) <choices> (only in )

Intercom voiceline for when the door is unlocked.

Loop Moving Sound? (loopmovesound) <boolean>

Makes the door's Start Sound loop until the door finishes moving.

Bug:If an already-looping sound is played with this enabled, it can continue forever. Further attempts to open or close the door will only add another looping sample to the noise.  [todo tested in?]
