A tracked body in XR. A body 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 skeleton and store this data on the [XRBodyTracker] object. Use [XRBodyModifier3D] to animate a body mesh using body tracking data. $DOCS_URL/tutorials/xr/index.html Returns flags about the validity of the tracking data for the given body joint (see [enum XRBodyTracker.JointFlags]). Returns the transform for the given body joint. Sets flags about the validity of the tracking data for the given body joint. Sets the transform for the given body joint.
