Fusion XR prototyping addons

The Magnets addon provides a simple way to attract an object to others when it has been ungrabbed.

Magnet types

Magnetic object are described with the IMagnet interface. Several kinds of magnets exist.


MagnetPoint are network behavior, that will look for an IMagnet within their magnetRadius (with a Physics.OverlapSphere) to be attracted to them.


MagnetTarget can attract other objects, but won't move. They do not need to be placed under a NetworkedObject.

If isPlaneMagnet is set to true, instead of attracking object to their transform's position, the MagnetTarget attract them to the neareast point to the projection plane it defines with new Plane(transform.up, transform.position).

If alignOnAllAxis is set to false, the attracked object will align its up axis with the magnet target y axis, but will leave the other axis untouched.


An object can contain several MagnetPoint. To make sure they they do not trigger all at once upon ungrab, but only the one the closest to a magnetic object, a MagneticCoordinator can be used. It prevents the MagnetPoint from looking themselves for a target, and will select the most appropriate magnet point based on its distance from a magnetic object.


A demo scene can be found in Assets\Photon\FusionAddons\Magnets\Demo\Scenes\ folder.
