env_bubbles

Code classes:

• CBubbling
• CBaseEntity (all ents)

env_bubbles is a brush entity present in all Source games. It is used to create a volume in which to spawn rising bubbles. The number and frequency of bubbles can be adjusted.

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