This video explains how to get setup with your first VR scene using the XR Interaction Toolkit in Unity. We install all the necessary VR packages to build an app to your headset (we use the Meta Quest in the video). We also explain how to get Oculus Link setup in order to play VR directly from the Unity Editor.

This video explains how to use the XR Device Simulator to control a VR rig from the Unity Editor using just the keyboard and mouse. Unity updated the XR Device Simulator in the XR Interaction Toolkit package version 2.3.0, so if you're using an older version of the package look at our other video.

This video explains the different forms of VR locomotion given to us by the XR Interaction Toolkit package in Unity. We cover teleportation, continuous movement by the joystick, snap turn, and all the forms of grab movement including two handed rotation and scaling. We also discuss how to avoid motion sickness in VR.

This video breaks down the function of XR Interactors and XR Interactables in Unity. We talk about the Ray and Direct interactors, as well as the Grab and Simple interactables. We explain how the Interactor Events can be used to codelessly change properties and call functions on components in your scene.

This video explains how to use the XR Socket Interactor component of the XR Interaction Toolkit in Unity to hold interactable objects at a set location. In addition, we discuss how you can use XR Interaction Layer Masks to manage interactions between interactors and interactables.
