I used the method introduced in this blog "Easy Controller Selection" (https://developer.oculus.com/blog/easy-controller-selection/). Basically I attached a line render to the controller model, and I am able to use it to select objects by pressing buttons. I wonder if I am able to grab game objects in the same way. I used to use Windows Mixed Reality to develop games, and they have native support of laser pointer. So I am able to use the laser pointer to select and grab gameobjects simply by attaching grabbable scripts. I know how to grab objects with OVR Avatar by attaching OVR Grabbable script, but I want to know if I can do the same thing without actually grab it with my hands.
TL;DR I want to use the laser pointer to grab object as dragging it towards or away from me.
