XRHandTracker

继承： XRPositionalTracker < XRTracker < RefCounted < Object

A tracked hand in XR.

描述

A hand tracking system will create an instance of this object and add it to the XRServer. This tracking system will then obtain skeleton data, convert it to the Godot Humanoid hand skeleton and store this data on the XRHandTracker object.

Use XRHandModifier3D to animate a hand mesh using hand tracking data.

枚举

enum HandTrackingSource:

HandTrackingSource HAND_TRACKING_SOURCE_UNKNOWN = 0

The source of hand tracking data is unknown.

HandTrackingSource HAND_TRACKING_SOURCE_UNOBSTRUCTED = 1

The source of hand tracking data is unobstructed, meaning that an accurate method of hand tracking is used. These include optical hand tracking, data gloves, etc.

HandTrackingSource HAND_TRACKING_SOURCE_CONTROLLER = 2

The source of hand tracking data is a controller, meaning that joint positions are inferred from controller inputs.

HandTrackingSource HAND_TRACKING_SOURCE_NOT_TRACKED = 3

No hand tracking data is tracked, this either means the hand is obscured, the controller is turned off, or tracking is not supported for the current input type.
