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.

• EnableDisable:

Enable / Disable

Enable/disable this entity from performing its task. It might also disappear from view.

• SetSpeakerName <target_destination>

Set the microphone to output through a different speaker entity.

Outputs

Fired in Measuring mode whenever the sound level changes.

• OnRoutedSound

Fired whenever a sound is routed out through the specified speaker (if any).

• OnHeardSound

Fired whenever this microphone hears any sound it cares about.
