    Dear Community,

    I have experienced some trouble when deleting an AR object with the new SelectionInteractable - Script on it placed in the scene. Is this an expected behavior? Or has somebody managed to delete such placed prefabs without bricking the scene?

    The main problem with this after placing and only hiding the objects instead of destroying them the scene will slow down fast.

    I would appreciate any help in this matter.

    Greets,
    Dan

    Hello,
    This was pointed out to us and is in our backlog. Some of our classes don't actually clean up all their references and registrations, and I need to do a pass on that in the very near future.

    Sorry for the hassle.

    Thank you for this information. This seems like a major bug for an AR - App.

    When can we expect a fix here? Or a practicable workaround? :)

    Awesome thanks - maybe there is such a workaround for the non blocking GUI as well when AR Raycasting as well :)

    Has this been fixed?! I have the latest Unity 2019.3 and XRToolkit 0.9.3 and anytime I delete an object than has some Interactable components on it it bricks the scene and nothing works anymore. This is a blocker. Am I missing something? Thanks much.

    Hey @roslim,
    The error behavior from the original thread when deleting objects should be properly handled now. XRI is cleaning up any of the references under the hood that were causing problems before. You will need to update to a newer version of the XRI Toolkit to take advantage of these fixes (currently at 2.1.0-pre.1).

    In terms of deleting the object, you can just use the standard Unity convention: 
    gameObject.Destroy()
    . Let us know if you have any other questions.

    sorry for my fool question, i am very new to this.
    i dont get what you mean. i just followed some tutorials on youtube, how to spawning objects and then using xr interaction to select, rotate, and scale object, and those scripts which related already provided by xr interaction toolkit right?. my problem is i dont understand how to make selection on spawned object in order to delete the object by clicking the delete button i created, as it is not included in video. thank you
