AR Workshop

Step 1

Create a new project that targets your desired platflorm

Step 2

Import packages from the packet manager

• ARKit XR Plugin
• ARCore XR Plugin
• ARFoundation

Step 3

Edit Project Settings > Player and add CameraUsageDescription

Create link.xml

<linker>
    <assembly fullname="Unity.XR.ARCore" ignoreIfMissing="1" preserve="all"/>
    <assembly fullname="Unity.XR.ARKit" ignoreIfMissing="1" preserve="all"/>
</linker>

Step 4

Set up scene

• AR Session
• AR Session Origin
  • AR Plane Manager
  • AR Point Cloud Manager

Step 5

void Start () {
	PlaneManager.planeAdded += PlaneManagerOnPlaneManagerAdded;
}

private void PlaneManagerOnPlaneManagerAdded(ARPlaneAddedEventArgs obj)
{
	var go = Instantiate(particlePrefab, obj.plane.transform);
	go.transform.localPosition = Vector3.zero;
	go.transform.localScale = Vector3.one;
}

Step 6

Minigame script

public class Minigame : MonoBehaviour
{
	public GameObject prefab;
	private int level;
	public List<GameObject> objects;
	public float size = 0.2f;

	void Awake()
	{
		level = 1;
		StartCoroutine(Game());	
	}

	void Update()
	{
		if (Input.touchCount > 0)
		{
			Touch touch = Input.GetTouch(0);
			var ray = Camera.main.ScreenPointToRay(touch.position);
			RaycastHit hit;
			if (Physics.Raycast(ray, out hit))
			{
				if (objects.Contains(hit.collider.gameObject))
				{
					Destroy(hit.collider.gameObject);
				}
			}
		}
	}


	IEnumerator Game()
	{
		for (int i = 0; i < level; i++)
		{
			var obj = Instantiate(prefab, transform);
			obj.transform.localPosition = Vector3.forward * Random.Range(-size, size) + Vector3.left * Random.Range(-size, size);
			obj.transform.localRotation = transform.rotation;
			objects.Add(obj);
		}

		yield return new WaitForSeconds(5f);
		level++;
		StartCoroutine(Game());
	}
}
