Introduction

The OpenSimulator avatar service stores user avatar parameters (height, visual parameters) and items that are attached and provides this on request.

TODO: Document remaining operations.

API

General notes

Unlike the asset service, the avatar service is an RPC interface. Therefore it exposes only one URI which is avatar (e.g. http://localhost:8003/avatar). The invocation of different operations (e.g. getavatar, setavatar) is controlled via a METHOD parameter.

Calls

getavatar

This returns data about a user's avatar. POST field is a urlencoded string like so

VERSIONMIN=0&VERSIONMAX=0&UserID=efc1b932-20e3-4298-8824-0f891fe3dc59&METHOD=getavatar

where

• VERSIONMIN is the minimum version client protocol compatible with this request. Currently unused, can set to zero.
• VERSIONMIN is the maximum version client protocol compatible with this request. Currently unused, can set to zero.
• UserID is the UUID of the avatar.
• METHOD is the XMLRPC method, in this case "getavatar".

If successful, example return is

• MAXVERSION can be ignored - this is accidentally being stored and retrieved on OpenSimulator 0.7.4 and before.
• MINVERSION can be ignored - this is accidentally being stored and retrieved on OpenSimulator 0.7.4 and before.
• METHOD can be ignored - this is accidentally being stored and retrieved on OpenSimulator 0.7.4 and before.
• UserID can be ignored - this is accidentally being stored and retrieved on OpenSimulator 0.7.4 and before. If it is present it will be the same as the requested UserID.
• AvatarType is the type of avatar. This can currently be ignored and will always be 1 for real avatars.
• AvatarHeight is the height of the avatar in meters.
• Serial is the serial number of the avatar parameters update.
• VisualParams is a comma separated list of integers that control aspects of the avatars appearance.
• Wearable_x0020_AvatarWearable_x003A_0> is an entry that controls the items that the avatar is wearing. The data is in the format <inventory-id>:<asset-id>. In the element format, AvatarWearable corresponds to the wearable type in OpenMetaverseTypes.WearableType. For instance, 2 is hair and 4 is shirt.
