Bevy 0.17.2 Tutorial: First-Person Camera

Code base: https://github.com/James8234/bevy_series/tree/main/project4 Learn how to build a first-person camera in Bevy (Rust). In this tutorial, we implement camera-relative player movement, mouse-driven camera rotation, and camera translation that follows the player — core systems used in almost every FPS game. We start with a live demo in the first seconds, then visually explain why the system works before diving into the code. You’ll learn how Bevy stores the Camera component, how to query it correctly (and why Query::single() is usually a bad idea), and how to rotate player input to match the camera’s direction. This video is part of a Bevy tutorial series, so copying the previous project is recommended. If you skipped earlier videos, the repo link is in the description so you can jump right in. Perfect for anyone learning Bevy, Rust game development, or first-person camera systems.
