Link to the app on google drive I have this app on gitHub but its not the exact same as this one, thats why I uploaded this version on google drive instead of gitHub
screenshot the screenshot also includes a summery of the problem
Newbie here, this might be a simple fix but I just haven't found it.
I have a menu with pictures/icons of furniture at the bottom of my screen. I want that when you click on one of the pictures and click on an anchor(place where I can put the object/asset), the object should be placed on the anchor where you're tapping
I tried logging to the debug console after tapping an anchor, just to see if the app recognizes what asset/object had been tapped on.
So if I tapped on the chair for example and then tapped on the anchor the app does manage to recognize that I tapped on a chair.
I have the sceneform plugin installed I have sceneform in my gradle dependencies
Sorry for all this code, just dont know where the problem is exactly.
My guess is that it only arises when placing the object and I wanted to add it for anyone who might need to see the missing parts

I expected that when I click on the a picture of a furniture item and then the anchor, the object would show up on the anchor. Instead when I do this the app kind of "glitches" and then I dont get any response from my taps
