The current version of Mugi Sim was written using OpenVR .The screenshot shows the menu with world-space canvas and buttons in Virtual Reality (VR).
You can point at the buttons with the VR controllers as well as use a joystick. Once the bounding boxes of the buttons are entered, you can use the select button or pull the trigger to move through the menus. I prefer this style to the menus where you have to walk toward and either “grab” or “punch” the buttons.
It has been great to rewrite the game in Unity. As well as providing the basis for a proper VR user interface, it is easy to program the Mugi to be controlled from first person by attaching a camera to the plane.
