Hi, I have a tile grid comprised of entites with physics objects. When I use the Camera.ScreenPointToRay(Input.MousePosition), I get an error stemming from the ray not colliding with anything. I know how to cast rays on entities using Collisionworld.CastRay. I am unsure of how to get the end position for my raycast though. Would I use Camera.Forward*rayLength? How does the camera get its ray direction? Any help is appreciated.
