using System.IO;
using UnityEngine;
using Vuforia;
public class SideLoadImageTarget : MonoBehaviour
{
    void Start()
    {
        VuforiaApplication.Instance.OnVuforiaStarted += CreateImageTargetFromSideloadedTexture;
    }
    async void CreateImageTargetFromSideloadedTexture()
    {
        Texture2D texture = new Texture2D(2, 2);
        string dataPath = Path.Combine(Application.streamingAssetsPath, "Vuforia");
        var allFiles = Directory.GetFiles(dataPath, "*.png", SearchOption.AllDirectories);
        foreach (var file in allFiles)
        {
            texture.LoadImage(File.ReadAllBytes(file));
            string fileName = Path.GetFileNameWithoutExtension(file);
            var mTarget = await VuforiaBehaviour.Instance.ObserverFactory.CreateImageTargetAsync(texture, 1, fileName);
            mTarget.gameObject.AddComponent<DefaultObserverEventHandler>();   
        }
    }
}
