On Anchors Changed
Triggers when AR Anchors have changed. AR Anchors can be added, updated, and/or removed every frame if there is an enabled AR Anchor Manager in the scene.
On Anchors Changed node, shown with Get Variable
Input Data Ports
| Port | Data type | Description |
|---|---|---|
| Target | GameObject | Target GameObject should have an enabled ARAnchorManager component. If you do not connect this port, this node searches for an enabled AR Anchor Manager component in the scene instead, and throws an exception if none is found. |
Tip
If your Script Machine Source is set to Graph, your graph asset cannot directly reference GameObjects in the scene. Use a Get Variable node to reference instantiated GameObjects.
