Env bubbles

env_bubbles in game, with density set to 35 and frequency set to 20

Template:Base brush It is used to create a volume in which to spawn bubbles, which rise upward. The number and frequency of bubbles can be adjusted.

Although env_bubbles is obviously intended for use in water, it can be used outside of water if such an effect is desired.

Availability

Template:In game all Source games except Portal 2

In code, it is represented by theCBubblingclass, defined in theeffects.cppfile.

Keyvalues

Bubble Count in Volume

Bubble frequency ([todo internal name (i)]) <integer>

Bubble emission frequency, in bubbles per second.

Speed of Current ([todo internal name (i)]) <integer>

The speed of the water current in the volume, used to move the bubbles.

Name (targetname) <string>[ Edit ]

SetDensity <integerRedirectInput/integer>

Sets the bubble density.

SetFrequency <integerRedirectInput/integer>

Sets bubble emission rate in bubbles per second.

SetCurrent <integerRedirectInput/integer>

Sets current speed in inches per second.

Parentname:

SetParent <stringRedirectInput/string>

Move with this entity. See Entity Hierarchy (parenting).

SetParentAttachment <stringRedirectInput/string>
