Env bubbles

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

Entity Description

An entity 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.

• density

<integer> Bubble Count in Volume

• frequency

<integer> Bubble emission frequency, in bubbles per second.

• current

<integer> The speed of the water current in the volume, in inches per second. Used to move the bubbles.

Inputs

Parentname:

SetParent <stringRedirectInput/string>

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

SetParentAttachment <stringRedirectInput/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 <stringRedirectInput/string>

As above, but without teleporting. The entity retains its position relative to the attachment at the time of the input being received.

ClearParent

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