Grasping and Rotation for Unity

[RaulAndrade]

Hello, I'm trying to grasp an object and rotate like knob.

I put 4 Box Colliders but, I don't know if it's the right thing, this only have physics:
--RigidBody: for detection of Collisions, Hinge Joint, etc.
-- Hinge Joint: movement limit to only rotate the X axis

The problem is that I do not recognize the grasping or do not rotate, but if I push with one finger if it does well

This use case is covered in the Interaction Engine documentation, on constraining an object's held position and rotation: https://github.com/leapmotion/UnityModules/wiki/Scripting-Interaction-Objects
