ar raycast mgr; ar env prob mgr) - ar camera - light (hdrLightEmission) extra interactive * package add: XR interactive toolkit (no for new input, go ahead for update) * root of interactive prefab root GameObject: - add * AR selection(mode:single/mult)/Translation/Rotation/Scale interactable component * (selection > put obj for selection visualizer) * [opt: use AR Select interactable -- Single] * collider * base quad obj with new material (unlit/transparent > with texture) * Extra 2: * AR camera: > add AR gesture mgr * AR session: > add XR interaction mgr * AR session: > add AR placement interactable (put to place prefab there, select mode: single/multi) * [opt: use AR Placement interactable -- Single] ====== AR Foundation Setup - markerless v2 ====== - build setting: switch to target platform * building setting > player setting: other > input setting: both - Package Manager from Unity registry : install (AR foundation) + (ARCore XR) + (XR interactive toolkit) * note: if xr interactive pop up, choose (no for new input, go ahead for xr update) - build setting > Player setting - other settings: - OpenGL before vulkan - min api : android api level 26 (store 30) - scripting backend: ILL2CPP - uncheck armv7 and check arm64 - input: both (need to restart Unity) - xr plug-in, check ARCore - create XR > AR session + AR session origin - ar session origin > add: ar plane manager - outliner > create XR > AR Default Plane, put it prefab - drag that plane prefab into AR Plane Manager (plane prefab) - direction mode: horizontal - drag that plane prefab into AR Plane Manager (plane prefab) - ar session origin > add: ar raycast manager - ar session origin > add: ar anchor manager - ar session origin > add: AR environment prob manager - (opt) HDRLightEstimation.cs into Directional Light, (put ar camera there); then, at AR camera manager, light estimation : everything - AR camera: > add AR gesture interactor - AR session: > add XR interaction mgr - AR session: > add AR placement interactable [opt: use AR Placement interactable – Single] (put to place prefab there, select mode: single/multi) - create GameObject Prefab - root GameObject > - add: collider (if its children no collider) - root GameObject > - add : AR selection interactable - (opt) quad obj prefab with new material (unlit/transparent > with texture) - put that selector prefab inside the GameObject prefab, hide, and drag it to selector indicator. - alternative: [opt for single prefab case: ARSelectionInteractableAuto.cs]; - root GameObject > - add : Translation [opt: ARTranslationInteractableAnchor.cs] - root GameObject > - add : Rotation/Scale interactable component - create UI - create canvas (1080x1920, scale with screen ) - image with moving sprite - ctrl+6: animation panel, select the image, and create, and drag image seq into animation - make the image not blocking user click, uncheck Image > Raycast Target - (opt) UIManager script --> Canvas object * AR Camera -> UIManager (AR Camera manager) * AR Session Origin -> UIManager (Placement manager) * Plane vis prefab -> Plane Prefab * Go To AR session > AR placement Interactable Single Anchor: * interactable events: add new, drag Canvas to object, and use PlacedObject() function as response - prefab animation ====== AR GPS ====== * import AR GSP package, right click add > AR GPS > Create basic scene structure * GSP stage object, uncheck "Use moving average" ====== UI Setup ====== * image with moving sprite * ctrl+6: animation panel, select the image, and create, and drag image seq into animation * make the image not blocking user click, uncheck Image > Raycast Target ====== Hardware Debug ====== * add package: android logcat * window > analysis > android logcat ====== Other related info ====== * https://www.quality-wolves.com/arkit-vs-arcore-vs-vuforia Tool: * view phone screen on windows: * https://github.com/Genymobile/scrcpy devwiki/arfoundation.txt Last modified: 2022/05/24 12:10by ying
