I'm working on a little "Tower of Hanoi" AR game in Unity using Vuforia, where the game is projected onto an image target.
Now I wanted to make the rings "fall" into place, so I added an invisible ground floor plane, with a box collider, and added mesh collider and rigid body to my ring.
Now there are quite a few questions about objects falling through the floor around and I tried many of the different suggestions (thickness of box collider, continuous instead of discrete collision detection,...) but none of them solved my issue.
Since this is my second little Unity project, I guess the issue is obvious (maybe my ring is too small (few centimeters) or something, but I'm not sure.
The problem is also, that I can't really see what is happening during runtime, since the camera has to find the image target first, after that the ring (currently testing only the bottom one) is gone and I just see the y-value of it's position changing.
Any help is much appreciated!
