env_doppler_emitter

This entity is not in the FGD by default.
It should not be put directly in a map because it is useless for most cases.

env_doppler_emitter is a point entity available in Black Mesa. This entity imitates specified sound, while parent is moving. If used with no parent, it will play sound once after TurnOn input. Used for some NPCs to play their movement sound. The NPCs is: npc_apache, npc_osprey, npc_alien_controller, npc_ichthyosaur, npc_gargantua. By default, it is not in FGD because of its very specific use.

Bug:Will not play specified sound if the sound is not precached.
