| − | * 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”
| |
| − | * Drag and drop this script into AR session origin
| |
| − | * Download free asset butterfly
| |
| − | * Double click on FBX
| |
| − | * Double click on Materials
| |
| − | * Select second sphere (blue metallic) butterfly_Albedo select the material in emissions
| |
| − | * 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
