  - name canvas object, BlinkCanvas, and choose as world space
  - RAWImage, width height: 2, color : black
  - drag Blink.cs to BlinkCanvas
  - select BlinkCanvas, create animation
    1. first frame: RawImage color alpha 0, RAWImage enabled

  - (updated turn aciton)
    - Locomotion system: uncheck old snap turn provider
    - add new ActionBasedSnapTurnProviderBlink.cs to it as Snap Turn Provider
    - link locomotionSystem, and drag BlinkCanvas to the blink.
    - check RightHand Snap turn, use reference, XRI RightHand Locomotion/Turn
- (extra) add blink to teleport
  - use modified ActionBased CountinuousMoveProvider, “ActionBasedContinuousMoveProviderBlink.cs”, it will track moving status
  - drag it to LocomotionSystem, (set system to “LocomotionSystem”, speed to 2, use Left Hand move action, LeftHand/Move, forward source: LeftHand Controller, reference LeftHand locomotion/move)
  - uncheck old Counitouse Move Provider component
  - update “blink.cs”, to support this
  - drag LocomotionSystem to BlinkCanvas's Blink component: Movement provider.
  - ———– optional: delay teleport after blink
  - go LocomotionSystem, uncheck old TeleportationProvider component
  - drag new custom TeleportationBlinkProvider to it
    - locomotion > system
    - BlinkCanvas > blink
  - remove manual blink call from RightHand Controller interactor, since we bake it into new script
  - remove Teleportation Area we on floor with new “TeleportationBlinkArea.cs”
  - do same for teleportation anchor
- (extra) add toggle for teleport controller
  - rename RightHand Controller as RightHand Teleport controller, duplicate as left and use left hand control copy control component and paste input value there
  - duplicate LeftHand controller as RightHand controller, and copy over input value as well
  - so that, you have 2 set of controller for hands, one set for interact, one set for teleport
  - turn off LeftHand and RightHand line visualizer for those straight line.
  - drag custom “Controller Mode Swap.cs ” script to XR origin, then put those 4 controllers there.
  - and check user reference: XRI RightHand Locomotion/Teleport mode activate
  - then, hide teleport set first.
  - — make right jobstick forward as activate teleport, while old left right to turn
  - RightHand teleport Controller > XR controller : selection action: changed to RightHand Locomotion/Teleport select
    - also, remove the select exited event for previous manual blink (if you keep it there, and turn it from runtime to off, it will make you need to press grip select button to be able to teleport)
    - to cancel teleport, you cant basically, or point to a place where teleport cant go to cancel
- (extra) add Oculus Hands.unitypackage
  - go oculus hands / material, change material to standard
  - set the prefab to LeftHand controler / RightHand controler prefab model
- (optional) offset teleport ray
  - create empty gameobject under teleport controller, name as “RayOriginTransform”
  - then, in Teleport controller > XR ray interactor : Ray original transform (drag the “RayOriginTransform” there)
  - then offset “RayOriginTransform”, so that the ray is at correct position you want
  - use XR device simulator, and play game, enable controller to see, and in Scene mode to move the transform
  - then disable game and disable XR device simulator
— Physical interaction
- create game object sphere with collider + XR grab interactable / (optional: XROffsetGrabInteractor.cs)
  - XR grab interactable:
    - movement type:
      - velocity tracking (more calculation, cant penetrate into other objects)
      - kinematic (ok calculation, can into other objects)
      - instantaneous (just follow)
    - (optional) custom Attach Transform to the center to grab, + attach point compatible mode:legacy
    - (optional) grab interatable: event on select point to it: first select / last exit
- so you can grab
  - (optional custom grab) Controller: XR ray interactor
    - anchor control: off
    - force grab: thing will fly to your hand
    - hit closest only: yes
    - hover to select: (off) auto grab
    - hide controller on select: on
- for physical calculation: player setting: time : fixed timestep 0.0138889 for 72hz physicals, instead of 0.02
(extra) direct controller
- duplicate RightHand control (rename old as ray controller), as RightHand direct controller
  - add component: XR direct interactor: hide controller on select ON
  - add component: sphere collider: 0.1 and is Trigger
(extra) object grab interactable script
- highlighter.cs:
  - hide and show optional select indicator geo
  - control outline width of outliner material assigned to the object
- colorChanger.cs for index button press trigger effect
  - it take original material + new material for trigger switch
- (no script method): index finger trigger is at grab interactable event : Activate/Deactivate

XR socket interactor: for take object into place

create empty object with sphere collider (as trigger),
add componenent: XR socket Interactor: (with your valid indicating material in Hover Mesh Material)
create a attachPoint empty object under it for it attach, then put it into “Attach Transform”
object with Grab Interactor will auto be put there once it touches its collider
use mask layer to filter out interaction

VR UI Canvas

create > XR > UI Canvas

XR Interaction Toolkit > XR Device Simulator, (disable it before export to device, this is for on screen testing w.o device)

drag it to scene
right click drag to move camera

setup
drag XR rig (BNG/Prefabs/Player) to scene (1 in Y)
create floor (convex)
delete default camera
on XR Rig/PlayerController/CameraRig/TrackingSpace/CenterEyeAnchor > add component: Tunnelling Mobile
- drag PlayerController to Motion Target
- motion detection: change to Linear Velocity (0, 1.5)
- replace edited motion stuffs script in (BNG Framework/Script/Core)
- modify PlayerControl componets
  - Locomotion manager: default locomotion both; uncheck from preference; none for toggle action
  - player teleport: control type : x button
  - player teleport: initiate teleport action: none
  - player teleport: uncheck for allow teleport rotation
  - smooth locomotion: speed 2: sprint speed: 4; strafe speed: 2; strafe sprint speed: 4; sprint input: left thumbstick; jump input: A button;
  - player teleport: tunneling → CenterEyeAnchor; smooth locomotion → PlayerController
  - player rotation: fader → CenterEyeAnchor
- modify CenterEyeAnchor:
  - Screen Fader: change fade in/out speed to adjust screen fade

Make Object Grabbale

object + rigidbody + Grabbale script + grabbale layer (so no push with your body)
- grab button: use Grabber button
- grab mechanic: (precise = grab offset; snap = in pivot position)
- grab physics: (none=cant grab; physicivelocity=ok; kinematic=laggy)
- remote grab: aimming with auto grab (linear, velocity, flick == how it fly to you)
- hand options (hide hand, parent to hand = fast calculation; snap hand = hand pose)
- can be dropped / snap to snap zone / force disable kinematic on drop
- break distance= release on hand drag gap when fighting with physics
- hand pose=grab pose
- secondary grab behavior (change hands or holds both hands)
- grab point (a transform like cup handle for grab point; require: snap hand model + grab snap)
  - create null object + Grab Point script
extra sound = Grabbable Haptics script + audio source + Collision sound script
(How it works: under
XR Rig/PlayerController/CameraRig/TrackingSpace/RightHandAnchor/RightControllerAnchor/RightController/Grabber;

Make Object highlight

replace BNG Framework/scripts/component, GrabbableHighlight.cs + OutlineEffect folder add
outline effect component into CenterEyeAnchor
object + GrabbableHighlight

others:

+ grabbable highligh material script
+ rigt helper
