CAVRNUS TYPES

CavrnusSpaceConnection

This is the most important object in Cavrnus. It represents a user’s connection to a Space. As such it is used to access Properties, hook Users, etc.

CavrnusAuthentication

This contains the Token received from the server upon a successful login. You can only ever have one active login at a time. At the moment, outside of just existing, this class doesn’t really “do” anything.

CavrnusSpaceInfo

This is the live info about a given Space. It can be used to create a Spaces List, like the one provided in Cavrnus by default.

CavrnusUser

This represents an individual user, and can be used to fetch their properties at runtime.

CavrnusLivePropertyUpdate

This is used to post Transient Updates.

CavrnusSpawnedObject

This represents an object that was spawned in a synchronized way at runtime using Cavrnus. It is used to manage that objects properties and, if desired, to delete it.

CavrnusRemoteContent

Represents a file that has been uploaded to the Cavrnus Servers.

CavrnusInputDevice

This represents a microphone, and can be used to create a Audio/Video selector, like the one provided in Cavrnus by default.

CavrnusVideoInputDevice

This represents a Video Source (both Cameras and Desktop Streams), and can be used to create a Audio/Video selector, like the one provided in Cavrnus by default.
