AR puzzle game : week 4

I tried to make other function in the AR puzzle game, like dragging or moving the object when finger tapping/dragging the screen. So first, I tried to find tutorial or plugin which could help me put this function in. And I use a script which can help me drag thing by touchscreen, however, it conflicts with the ARKit plugin means they can't work together very well. I still need the depth system in the AR game so I will try to get the paid developer account and try the new function of ARKit next week.
