@MainActor @preconcurrency class BodyTrackedEntity

An entity used to animate a virtual character in an AR scene by tracking a real person. Like a ``ModelEntity``, a ``BodyTrackedEntity`` has a ``ModelComponent`` that defines its physical appearance. Unlike a model entity, a body-tracked entity lacks the components required to participate in collisions or physics simulations. Instead, a ``BodyTrackingComponent`` drives the positioning and arrangement of the entity based on tracking information from the AR session. ![Diagram showing the components present in the body-tracked entity.](BodyTrackedEntity-1) For an example of how to use a body-tracked entity, see <doc://com.apple.documentation/documentation/arkit/content_anchors/capturing_body_motion_in_3d>.
