AugmentedImage.TrackingState always equals TrackingState.Tracking #607

Open dorkbot opened 5 years ago

dorkbot commented 5 years ago

SPECIFIC ISSUE ENCOUNTERED

I'm testing this scene -> https://github.com/google-ar/arcore-unity-sdk/blob/master/Assets/GoogleARCore/Examples/AugmentedImage/Scenes/AugmentedImage.unity And this Class -> https://github.com/google-ar/arcore-unity-sdk/blob/master/Assets/GoogleARCore/Examples/AugmentedImage/Scripts/AugmentedImageExampleController.cs

Once an image is tracked, it is always tracked. AugmentedImage.TrackingState always equals TrackingState.Tracking, even if the image is gone (closed). The result is that the AR 3D prefab object never goes away.

VERSIONS USED

STEPS TO REPRODUCE THE ISSUE

  1. Put a Debug.Log in AugmentedImageExampleController
  2. Build to device and look at Logcat

WORKAROUNDS (IF ANY)

Using AugmentedImage.TrackingMethod gives a better result.
