Hello! I can't download image target from the Application.persistentDataPath through VuforiaUnity.StorageType.STORAGE_ABSOLUTE. The path to the file is correct, checked through the DataSet.Exists, does not give an error. Help me please!
Here is my script:
public class SDCardDataSetLoader : MonoBehaviour
{
// specify these in Unity Inspector
public GameObject augmentationObject = null; // you can use teapot or other object
public string dataSetName = "MM_Spaceport.dat";
void Start()
{
VuforiaARController.Instance.RegisterVuforiaStartedCallback(LoadDataSet);
}
void LoadDataSet()
{
string pathDataSet = Application.persistentDataPath + "/" + dataSetName;
print(pathDataSet);
if (!DataSet.Exists(pathDataSet, VuforiaUnity.StorageType.STORAGE_ABSOLUTE)) {
Debug.LogError("Data set " + pathDataSet + " does not exist.");
return;
} else
print("good path");
ObjectTracker objectTracker = TrackerManager.Instance.GetTracker<ObjectTracker>();
DataSet dataSet = objectTracker.CreateDataSet();
if (dataSet.Load(pathDataSet, VuforiaUnity.StorageType.STORAGE_ABSOLUTE)) {
objectTracker.Stop(); // stop tracker so that we can add new dataset
if (!objectTracker.ActivateDataSet(dataSet)) {
Debug.Log("<color=yellow>Failed to Activate DataSet: " + dataSetName + "</color>");
}
if (!objectTracker.Start()) {
Debug.Log("<color=yellow>Tracker Failed to Start.</color>");
}
int counter = 0;
IEnumerable<TrackableBehaviour> tbs = TrackerManager.Instance.GetStateManager().GetTrackableBehaviours();
foreach (TrackableBehaviour tb in tbs) {
if (tb.name == "New Game Object") {
tb.gameObject.name = ++counter + ":DynamicImageTarget-" + tb.TrackableName;
tb.gameObject.AddComponent<DefaultTrackableEventHandler>();
tb.gameObject.AddComponent<TurnOffBehaviour>();
if (augmentationObject != null) {
GameObject augmentation = (GameObject)GameObject.Instantiate(augmentationObject);
augmentation.transform.parent = tb.gameObject.transform;
augmentation.transform.localPosition = new Vector3(0f, 0f, 0f);
augmentation.transform.localRotation = Quaternion.identity;
augmentation.transform.localScale = new Vector3(0.005f, 0.005f, 0.005f);
augmentation.gameObject.SetActive(true);
} else {
Debug.Log("<color=yellow>Warning: No augmentation object specified for: " + tb.TrackableName + "</color>");
}
}
}
} else
Debug.LogError("<color=yellow>Failed to load dataset: '" + dataSetName + "'</color>");
}
}
