continuous
TypeScript
static get continuous(): AnchoringComponent_TrackingMode
Swift declaration
static let continuous: AnchoringComponent.TrackingMode
Continuously anchors the entity to its target based on the target's realtime location
and hides the entity when the target is no longer in frame.
`continuous` means the `Entity` will track the target anchor continuously.
The `Entity` moves with the anchor and is unanchored if the target anchor disappears or no longer meets the target requirement.

once
TypeScript
static get once(): AnchoringComponent_TrackingMode
Swift declaration
static let once: AnchoringComponent.TrackingMode
Anchors the entity to the target on the first frame the target is found.
`once` means the `Entity` transform is evaluated only once when the target anchor presents and the `Entity` is anchored.
If the target anchor moves or disappears later, the `Entity` stays in place.

predicted
TypeScript
static get predicted(): AnchoringComponent_TrackingMode
Swift declaration
static let predicted: AnchoringComponent.TrackingMode
Continuously anchors the entity to its target based on the target's predicted location
and hides the entity when the target is no longer in frame.
`predicted` means the `Entity` will be updated whenever the corresponding anchor is updated
but its transformation will be `ARKit` prediction.
If the target does not support prediction, `predicted` behaves the same as `continuous`.
