Learn to build a video game from scratch using Rust and Bevy. This first chapter covers setting up your game world, creating a player character, and implementing movement and animations.
Learn procedural generation techniques to create dynamic game worlds.
Learn to build a data-driven character system in Bevy. We'll use a RON file to configure character attributes and animations, create a generic animation engine that handles walk, run, and jump animations, and implement character switching.
Let's make the player interact with the world properly, no more walking through trees, water, or rocks. We'll implement z-ordering so they can walk behind objects, giving your 2D game true depth. Also, you'll build a collision visualizer for debugging.
Build an inventory system to collect items from the world, then zoom in and add smooth camera follow.
Learn to build a particle system with magical powers and create stunning particle effects. Learn custom shaders, additive blending, and how to make your game feel alive.
Build intelligent enemies that hunt and attack the player.
Each chapter has its own directory with a complete, runnable project. Navigate to the chapter directory you want to explore and run:
cd chapter1 # or chapter2, chapter3, chapter4, chapter5, chapter6
cargo runNote for Linux users on Wayland: if you see rendering artifacts, run the app with the X11 backend:
WINIT_UNIX_BACKEND=x11 WAYLAND_DISPLAY= cargo runCommunity Tip: This optimization was pointed out by one of our community members, thank you for helping make this tutorial better!
Bevy's default debug configuration can lead to performance issues: scenes that should run smoothly might drop to unplayable framerates, or large assets might take minutes to load.
The Bevy team documents this issue and provides a solution.
Add these optimizations to your Cargo.toml:
# At the bottom of your Cargo.toml
# Enable a small amount of optimization in the dev profile
[profile.dev]
opt-level = 1
# Enable a large amount of optimization in the dev profile for dependencies
[profile.dev.package."*"]
