Hi again. Beside a sci-fi door I have a numeric keyboard to enter a passcode. The keyboard has its own display. Each key has a mesh collider and a FSM. The fsm uses Mouse Pick Event (set to every frame) and sends an event on Mouse Down. That event activates a state where a key sound is played (play sound) and a number is written (Set Visibility) on the display. My problem is that the FSM never detects the Mouse Pick Event. It remains freezed on the Mouse Pick Event state. I suspect that it can be caused by a wrong Ray Distance. Since I have no idea of the ray distance to use, I am trying various lenght, but nothing changes. And nothing happens also if I set a very long ray distance (10000 or more). How can I get the right ray distance to use? Is it the problem or I am probably forgetting something else? Ho can I solve that? Best if using only PlayMaker.
