Computing and Science Fiction. A graphical representation of a person or
character in a computer-generated environment, esp. one which represents
a user in an interactive game or other setting, and which can move about in
its surroundings and interact with other characters.
— Oxford English Dictionary (draft entry), 2008.
Once a human being enters Habitat, he or she takes on the visual form of an Avatar,
and for all intents and purposes becomes one of these new-world beings.
— Habitat, Lucasfilm Games, 1986.
An avatar is the form of a user in a given world.
In general, some components may (and do) appear in multiple places over the hierarchy of an avatar:
|AvatarUserReferenceAssigner||#on avatar equip, this assigns the reference of the user that equipped the avatar to the slot assigned to the assigner's target.|
|SimpleAwayIndicator||This applies the away material to a mesh target MeshRenderer or SkinnedMeshRenderer when the user equipping the avatar goes to away state.|
Commonly the avatar root will contain the following components:
|AvatarRoot||Indicates that this slot is the root of an avatar.|
|Grabbable||Indicates the avatar can be grabbed.|
|ObjectRoot||Indicates that this slot is the root of an object.|
|PBS_RimMetallic||The #away material of the avatar.|
|SimpleAvatarProtection||Sets permissions such that only the user bound to the avatar may equip and save it.|
Humanoid avatars also contain:
|VRIK||Computes the logic to map the input #IK Targets to #IK Proxies.|
|VRIKAvatar||Chooses when and how to bind the User's controls to the #IK Proxies.|
Avatar nodes represent a strongly identifiable piece of the avatar, such as LeftHand or Head.
With VRIK-based avatars an Avatar Node is named <pose node name> Proxy by convention, and contains:
- AvatarObjectComponentProxy (Component) - This copies the global transform of the avatar node, onto a target node (at least it appears to). Scans for the node kind identified by the AvatarPoseNode (Component) will find the target of the proxy as well.
- A child slot named Target - This is where the part of the avatar model will actually try to go to. - Ex: A proxy moves to exactly where a VR tracker is in space, the Target offsets that tracker back to where that body part should be. - Avatar calibration is done by moving the Target slot under the proxies being calibrated.
The Head node of the avatar is usually where the avatar's voice comes out of, and so usually contains these additional components:
|AvatarVoiceSourceAssigner||Assigns the audio stream of the user #on avatar equip. There may be multiple of these.|
|AvatarAudioOutputManager||Configures the avatar's AudioOutput with the configured settings based on the user voice setting.|
|AudioOutput||Emits the user's voice. Many fields on this component are driven by the AvatarAudioOutputManager.|
|AvatarVoiceRangeVisualizer||Configures the whisper bubble for the user based off AvatarAudioOutputManager provided settings.|
|VisemeAnalyzer||Computes the values to be routed to DirectVisemeDriver elsewhere in the avatar, which drives blendshape movements.|
In addition, the Head slot contains a child slot named Voice Range Visual. This is the whisper bubble, the slot is inactive unless the equipped user is in the whisper voice mode. This slot commonly contains:
|MeshRenderer||The visual part of the whisper bubble.|
|PBS_IntersectMetallic||The material applied to the whisper bubble. Changes based on the user's audio volume.|
Centered Root - VRIK specific
This slot represents where Neos thinks the center of the avatar is.
In World Lifecycle
Blocking avatar equip
Apply the AvatarEquipBlock component to the avatar's root.
