I am using latest vuforia 9.4.6 with. 2019.3.5 editor but that solution didnt work because  DefaultTrackableEventHandler script resets itself when editor opens.

So what i did is:

tb.gameObject.GetComponent<DefaultTrackableEventHandler>().OnTargetLost = new UnityEngine.Events.UnityEvent();

      tb.gameObject.GetComponent<DefaultTrackableEventHandler>().OnTargetFound = new UnityEngine.Events.UnityEvent();

in my script.

I solved the issue with changing code in DefaultTrackableEventHandler script

public UnityEvent OnTargetFound;

to

 

public UnityEvent OnTargetFound = new UnityEvent();

public UnityEvent OnTargetLost = new UnityEvent();

Excuse me what version of vuforia are you using? i have a problem update remotely targets.

I solved the issue with changing code in DefaultTrackableEventHandler script

Hello Amefuri,

You can bundle the .dat and .xml file that are associated with your Device Database and load them at run time. This article provides some examples of how to load a database from the SD card: https://library.vuforia.com/articles/Solution/Working-with-Vuforia-and-Unity.html#load-dataset

This old post by dm3d has an example script of loading and activating a Device Database at runtime and then assigning it an augmentation: https://developer.vuforia.com/forum/faq/unity-load-dataset-setup-trackables-runtime

Let me know if you have further questions on this topic.

Thank you I have managed to solve most of my problems but there is one issue please help me:

Dynamic data set loader script: Loops TrackableBehaviour and adds them DefaultTrackableEventHandler script.

tb.gameObject.AddComponent<DefaultTrackableEventHandler>();

When i try to access that script with GetComponent, for OnTargetFound event, it gives null exception:

tb.gameObject.GetComponent<DefaultTrackableEventHandler>().OnTargetFound.AddListener(CarFound); is giving null exception

tb.gameObject.GetComponent<DefaultTrackableEventHandler>().OnTargetFound.RemoveAllListeners(); is giving null exception

I can reach DefaultTrackableEventHandler component but cant do anything with it.

DefaultTrackableEventHandler dteh = tb.gameObject.GetComponent<DefaultTrackableEventHandler>(); is NOT giving null exception

b.gameObject.GetComponent<DefaultTrackableEventHandler>().enabled = false; is working as well

void CarFound()

    {

  augmentation.SetActive(true);

}

Please help me
