About the Book
Build real games in Rust with Bevy, from first compile to shipped release. This book treats you like a teammate on a production project. You start with a clean toolchain and a fast workspace, then move through ECS patterns, rendering, assets, UI, physics, animation, AI, networking, and release. Every step is backed by working examples and clearly labeled code. No filler, only what helps you ship.
Early on, you see how project layout, version pinning, and a tidy plugin graph keep builds quick and stable. Components and bundles are shown in context, with explanations of why data layout affects cache behavior and frame time. Queries and filters are demystified, so the systems you write stay simple and parallel. The style is hands on. You read a short paragraph, then you read code that compiles.
Rendering is practical. You work with wgpu backends across Vulkan, Metal, D3D12, and WebGPU. You add a custom render graph node, tune PBR materials, and manage tone mapping and HDR. When ray traced lighting makes sense, you see a path to test it, along with honest fallbacks and baking so your project stays predictable.
Production teams live on assets, so the pipeline is a first class topic. You set up AssetServer with hot reload, write custom AssetLoader code for binary and text formats, embed gameplay data in glTF extras, and ship textures through a KTX2 flow that trims memory and download time. Every section includes code you can paste and adapt.
For 2D, you get sprite batching, atlas animation, tilemaps that scale, and pixel perfect cameras that handle scaling and letterboxing without blur. Tools matter during development, so there are clear examples using bevy_ui with Taffy layout, bevy_egui panels and inspectors, input mapping with Leafwing, and clean focus and text input hygiene.
Physics coverage is balanced and concrete. You configure Rapier and Avian, set collision layers, CCD, and joints, build character controllers, read contact data, and wire triggers and queries into gameplay events. Animation and VFX chapters show skeletal and property animation with AnimationPlayer, state driven blending with notifies, GPU particles with Hanabi, and material effects like glass and emissive, all with concise examples.
Networking is explained through patterns that ship. You build an authoritative client server with renet and replicon, add client prediction and reconciliation with Lightyear, and implement rollback with GGRS. Transports cover quinnet and Steamworks with a connection flow that testers can follow. Web and WASM builds get equal care, including COOP and COEP headers, feature probing, and asset delivery that works inside the browser.
Performance and release tie it all together. You profile with Tracy and Chrome trace, track meaningful percentiles, and fix what moves the needle. Then you package with cargo dist, sign and notarize where required, verify Steam integration, and run a CI matrix that produces clean artifacts for desktop and web.
When deadlines are close, you need a guide that shows exactly what to build and why it works
Example first: every concept is paired with working code and short explanations.
Production focus: choices are justified by stability, performance, and team workflow.
End to end coverage: setup, ECS, rendering, assets, UI, physics, animation, AI, networking, performance, and release.
Actionable details: version pins, feature flags, device limits, headers for web, CI scripts, and packaging steps.
If you want a guide that helps you build, measure, and ship, this book gives you the pieces that matter and the code that proves it.
