# How to snap objects into place in VR

Advanced Framework Pro snaps with a pair of components: a connector on the movable object and an anchor on the target. When the player holds the object near the anchor, a ghost shows where it will land, and releasing places it exactly, oriented correctly no matter how it was grabbed. By the end of this you will have a part that fits only its own slot, and optionally one that sits flat on any wall or table.

## At a glance

```
Movable object (grabbable)
└─ BPC_Connector_Anchor      Connector ID = Battery, Release Type, Search Distance,
                             Show Snapping Preview, Show Anchors On Search
   or BPC_Connector_Surface  Rotate On Surface, Wall Rotation Adjustment
Target
└─ BPC_Anchor                Connector IDs To Allow = [Battery]  (empty = any)
Events on the anchor: attach, detach
```

## Steps

1. Custom Depth-Stencil must be on for the preview; the Setup window's Required page turns it on (*Custom depth with stencil*).
2. Make the object grabbable first; see [How to make an object grabbable](make-object-grabbable.html).
3. On the object, add `BPC_Connector_Anchor` and move it to the point that should meet the target. Set **Connector ID**, for example `Battery`.
4. On the target, add `BPC_Anchor`, place it where the object should sit, and add the same ID to **Connector IDs To Allow**. Leave the list empty to accept any connector.
5. Set **Release Type** on the connector: attach, snap in place, or physics drop.
6. Turn on **Show Snapping Preview** for the ghost and, if useful, **Show Anchors On Search** to reveal compatible slots while the object is held.
7. For placing on surfaces instead of slots, use `BPC_Connector_Surface` and choose **Rotate On Surface**: keep rotation, align to the surface, or align and face the player.

## Notes

Bind to the anchor's attach and detach events to react: a machine that starts when all parts are in, a lamp that lights when the bulb is seated.

Keyed IDs give you assemblies: each part fits only its own anchor, and one anchor can list several IDs.

**Search Distance** sets how close the object must come before a slot is offered. Keep it small for dense assemblies.

Multiplayer

Attachment replicates; every client sees the same connection.

**Nothing snaps?** The connector ID is missing from the anchor's allow list, or Search Distance is too short.

`Map_Examples_Snapping` has five stations: battery and bulb slots, the three release types on a tray, surface placement with Requires Tag, a rifle assembled from keyed parts, and a gear machine driven by anchor events.
