In depth learning on Scene Configuration can be found in this course in Motive Academy.

Use a grabbable and a hinge Joint to create a lever with limited motion.

Create a lever on an object activated by grabbing. Levers need to move from a pivot position properly so ensure this is set up properly (VR Grabbables & Unity Joints)

Lever Hinge

Gameobject contains the Hinge Joint and VR Grabbable logic.

Rigidbody

Field	Value
Use Gravity	false
Is Kinematic	true
Collision Detection	Continuous Speculative

Hinge Joint

Field	Value
Axis + Secondary axis	Adjust identity matrix to pivot on desired axis.
Connected Rigidbody	Rigidbody of main/body object
Limit Rotation	true
Lower Rotation	Desired negative degrees from rest position
Upper Rotation	Desired positive degrees from rest position

negative/positive degrees = direction of rotation

VR Grabbable

Field	Value
Allow Distance Grab	false
Snap Position	Never
Snap Orientation	Never
Grab points	Collider(s) the user will be grabbing
Release Behaviour	Leave and Reset Rigidbody
Move Mode	Physics

Joint Effects

Used to fire SFX/Haptics on upper/lower limit events

Field	Value
Lower Limit Reached - Haptic Effect	Bump (VRHapticEffect)
Upper Limit Reached - Haptic Effect	Bump (VRHapticEffect)

Usable World Object

Required to connect to the “use object” input for object interactions.

Field	Value
On Use	Connect to any animations, SFX, etc. required for the action.

Joint Boolean State Setter

Binds the hinge Joint to a Boolean Behaviour State. In this case, sets the state to “true” when the lever is at the lower limit.

Field	Value
State	Whatever name you want to use as a variable when authoring
Lower Limit State Setting	true
Upper Limit State Setting	false

Motive Scene Object

Required for Scene Objects, can be skipped if deploying as an asset.

Lever Object

The prefab of the lever itself with mesh renderers + colliders.

Collider

If possible use a primitive collider, unless you’re sure the user may only grab the object on the lever handle alone.

Field	Value
Trigger	Generally true unless this item needs physics
