| − | Attended the "Create Augmented Reality App" Webinar by Gen In finiti Academy, 13 Aug 2020, 7.30pm-9.30pm
| |
| − | - Conducted by Emmanual Tay
| |
| − |
| |
| − | * Change build settings to Android/mobile
| |
| − | * Delete Main camera and Directional Light
| |
| − | * Window > Package Manager > AR Foundation > Install
| |
| − | * Window > Package Manager > ARCore XD Plugin > Install
| |
| − | * Window > Package Manager > ARkit Xr Plugin > Install
| |
| − | * Rightclick on Hierarchy Window > XR > AR Session origin
| |
| − | * Double click the tiny AR Session origin > look under inspector > tag: MainCamera
| |
| − | * Rightclick on Hierarchy Window > XR > AR Session (coordinates the real world)
| |
| − | * Rightclick on Hierarchy Window > XR > AR Default Plane
| |
| − | * Click on AR Session Origin in Hierarchy > Look in Inspector > Add Component > AR Raycast Manager (checks for floor)
| |
| − | * Click on AR Session Origin in Hierarchy > Look in Inspector > Add Component > AR Plane Manager (allows you to tag and project things)
| |
| − | * Now we want to add a plane prefab, first we create a folder in project called “prefabs”
| |
| − | * Drag the AR Default Plane into the Prefabs folder
| |
| − | * Drag the blue AR Default Prefab into inspector slot for AR Session Origin > plane manager > plane prefab
| |
| − | * Create in project a scripts folder
| |
| − | * Create a new C# script “PlaceOnPlane.cs” - open it in editor of choice (be careful about naming of file)
| |
| − | * Drag and drop PlaceOnPlane script into AR session origin
| |
| − | * Download free asset butterfly (just go to Asset Store and look for the free Animated Butterly asset
| |
| − | * Download and import the butterfly asset - THIS ONE: https://assetstore.unity.com/packages/3d/characters/animals/butterfly-animated-58355
| |
| − | * Newly imported Butterfly asset folder > Double click on FBX > Double click on Materials
| |
| − | * Select second sphere (blue metallic) butterfly_Albedo > select the image material in emissions (otherwise butterfly will not show up)
| |
| − | * Assets > Butterfly Animated > Prefab > left click on butterfly and drag it inside Place On Place Model (inside AR Session Origin)
| |
| − | * Project Settings > Player > Other setting > Identification > Minimum API Level > Set to Android 7.1
| |
| − | * Build and Run
| |
| − | * Copy the apk to your phone
| |
| − | * Recklessly install it on your phone
| |
| − | * AR BUTTERFLY APP COMPLETE
