What problem does it solve? Setting up VR/AR interaction in Unity requires wiring many XRI components with exact property names, and reflection-based calls fail silently when names are wrong. This Skill provides validated workflows for building XR rigs, grab/socket/ray interactors, teleportation, and XR UI without guessing component APIs. ## Core Features & Use Cases - XR Rig Setup and Diagnostics: Validate the scene with xr_check_setup, then create an XR Origin with camera and controllers, an interaction manager, and an XR UI event system. - Interactors and Interactables: Add ray, direct, and socket interactors plus grab/simple interactables with correct collider and Rigidbody configuration. - Locomotion and XR UI: Configure teleportation areas/anchors, continuous movement, snap or smooth turning, haptics, interaction events, and world-space canvases. - Use Case: You want a grabbable cube in VR. Run xr_setup_rig, add a direct interactor to the left controller, then call xr_add_grab_interactable with VelocityTracking movement to get a physics-based grab working immediately. ## Quick Start Ask the assistant to set up an XR rig with a ray interactor on the right controller and a grabbable cube using the unity-xr skill.
