Manual avatar creation

Last updated：2022-12-23 13:03

Overview

The ZegoAvatar SDK provides the manual avatar creation feature. Users can adjust different facial parts (such as the eye size, nose width, and mouth size) of their virtual avatars based on their own aesthetic preferences to build unique virtual avatars for themselves. This feature can be widely used in various game scenarios.

Prerequisites

Before you implement the manual avatar creation feature, ensure that the following conditions are met:

Implementation steps

Refer to the following procedures to implement the manual avatar creation feature. After the basic virtual avatar is created, call the setFaceShape API and introduce the faceshapeID (adjustable facial dimension), value (avatar creation coefficient), and other parameters to set or modify the dimensions of facial parts. For more information about adjustable facial dimensions, see the following table. We also describe all adjustable facial dimensions (faceshapeID) in helper/ZegoCharacterHelper.h.

/** Set the avatar creation coefficient. For the value of faceshapeID, see the following table. Constants defined in ZegoCharacterHelper can be used directly.*/
[_characterHelper setFaceShape:FACESHAPE_BROW_SIZE_Y value:0.3];

Adjustable facial dimensions include:

In the following dimensions, the shape in corresponding face positions (such as the length, thickness, height, size, and angle) varies with the value. That is, a larger value indicates a greater shape change in the corresponding position.
