Unity XR Interaction Toolkit Skills

Correct class names to anchor on:

• XRInteractionManager
• XROrigin
• XRRayInteractor
• XRDirectInteractor
• XRSocketInteractor
• XRGrabInteractable
• XRSimpleInteractable
• TeleportationProvider
• TeleportationArea
• TeleportationAnchor
• ContinuousMoveProvider
• SnapTurnProvider
• ContinuousTurnProvider
• TrackedDeviceGraphicRaycaster
• XRUIInputModule
• TrackedPoseDriver

Routing:

• For non-XR Canvas UI creation -> use ui
• For architecture or lifecycle decisions in XR gameplay code -> load advisory modules such as architecture, patterns, async, or scriptdesign
• For exact component property names and full workflow examples -> load API_REFERENCE.md

Quick Start

import unity_skills as u

u.call_skill("xr_check_setup")
u.call_skill("xr_setup_rig", name="XR Origin")
u.call_skill("xr_add_ray_interactor", name="Right Controller")
u.call_skill("xr_add_direct_interactor", name="Left Controller")
u.call_skill("xr_setup_teleportation")
u.call_skill("xr_setup_turn_provider", turnType="Snap", turnAmount=45)
u.call_skill("xr_add_grab_interactable", name="MyCube", movementType="VelocityTracking")

Workflow Summary

Rig Setup

1. Run xr_check_setup.
2. Create the rig with xr_setup_rig.
3. Ensure XR UI input exists with xr_setup_event_system.
4. Add at least one interactor per controller.

Grab Setup

• Direct hand grab: xr_add_direct_interactor + xr_add_grab_interactable
• Distance grab: xr_add_ray_interactor + xr_add_grab_interactable
• Socket placement: xr_add_socket_interactor + grabbable object

movementType defaults matter:

• VelocityTracking: best general-purpose physical grab
• Kinematic: use for handles/tools that should not get stuck
• Instantaneous: best for precise remote grab

Locomotion Setup

• Teleport: xr_setup_teleportation + xr_add_ray_interactor + xr_add_teleport_area/xr_add_teleport_anchor
• Continuous locomotion: xr_setup_continuous_move
• Turn: xr_setup_turn_provider

Comfort default: snap turn + moderate move speed (~2.0 m/s).

XR UI

1. Convert Canvas with xr_setup_ui_canvas
2. Ensure xr_setup_event_system
3. Add a ray interactor on the controller that should click UI

Collider Configuration Matrix

This is the most important XR anti-hallucination table in the repo.

Critical rules:

1. XRGrabInteractable needs a Rigidbody.
2. A grabbable collider must not be trigger.
3. A direct interactor collider must be trigger.
4. Dynamic mesh colliders must be convex.
5. Socket colliders should be trigger-only overlap zones.

Version Compatibility

Important Notes

1. Scenes should normally have exactly one XRInteractionManager.
2. Most locomotion skills assume an XROrigin already exists.
3. Package installation or reconfiguration can trigger Domain Reload. Wait before retrying XR calls.
4. Use InteractionLayerMask for interactor/interactable filtering.
5. For custom XR scripts, prefer XRI lifecycle hooks and events over Update() polling when possible.

Minimal Example

import unity_skills as u

u.call_skill("xr_setup_rig", name="XR Origin", cameraYOffset=1.36)
u.call_skill("xr_setup_event_system")
u.call_skill("xr_add_ray_interactor", name="Right Controller", maxDistance=30, lineType="StraightLine")
u.call_skill("xr_add_grab_interactable", name="Tool", movementType="VelocityTracking", throwOnDetach=True)
u.call_skill("xr_configure_haptics", name="Right Controller", selectIntensity=0.7, selectDuration=0.15)

Exact Signatures

Exact names, parameters, defaults, and returns are defined by GET /skills/schema or unity_skills.get_skill_schema(), not by this file. Before configuring XR component properties in detail, load API_REFERENCE.md. XR property names are reflection-sensitive.
