Is it possible to build a mobile chess game, where fine raycasts are required (not just the bad aim the examples show - at least so far, i can't seem to properly raycast with any of the gun examples)
Can we do a direct raycast from finger position on the screen?
It sounds like what you're looking for is pretty in-line with what is available through the Focused Interaction API. You will be able to use mobile screen input (tap/drag) to raycast from that input point. This should be a good starting point for you!
