10 Things I learnt from my first HoloLens app
summary
Build of a minimalist HoloLens game called Paddle Bounce uses Unity + the Mixed Reality Toolkit and Visual Studio to prototype in-editor with gaze/hand simulation, then deploys as a UWP x86 app. Physics uses a Rigidbody mass ~27 g, a physics material with bounciness ~0.9, and audio via the Microsoft spatializer. Spatial mapping prevents the ball from “falling off into the ether.” Debugging happens live in the editor and on-device; result is a working MVP with clamped FOV, input handlers, and source on GitHub.
