WebAssembly Game Development
Build high-performance browser games using Rust, WebAssembly, and the WebGPU API
🔧 Start BuildingBuild Your First WebAssembly Game
Learn to create a 2D platformer game that runs in the browser using Rust-to-WASM compilation and WebGPU rendering
Why WebAssembly?
WebAssembly provides near-native performance for complex computations like physics engines and AI pathfinding in browser games
🚀 Performance MetricsWebGPU Integration
Render games at 60fps using Rust's WebGPU bindings for modern graphics features like compute shaders and ray tracing
� GPU ProgrammingGetting Started
1. Setup Development Tools
Install Rust, Ebit, WebAssembly toolchain, and WebGPU emulation tools
npm install -g w wasmer ebit rustup target add wasm32-unknown-unknown cargo install wasm-bindgen-cli
2. Create Project Structure
Initialize a new Rust project with WebGPU support
cargo new wasm_game cd wasm_game cargo add webgpu
3. Write Game Logic
Implement physics, game loop, and player controls in Rust
// src/main.rs
#[wasm_bindgen]
pub struct Game {
player: Player,
camera: Vec2,
}
#[wasm_bindgen]
pub fn new() -> Game {
Game {
player: player::default(),
camera: Vec2::ZERO,
}
}
#[wasm_bindgen]
pub fn tick(&mut self) {
// Game update logic
}
4. Compile to WebAssembly
Build and optimize your code for the browser
cargo build --target wasm32-unknown-unknown wasm-bindgen target/wasm32-unknown-unknown/debug/wasm_game.wasm \ --out-dir . --web
5. Host in HTML
Create a canvas and load your game module
// index.html
<canvas id="game"></canvas>
<script type="module">
import init from './wasm_game.js';
init();
</script>
Performance Comparison
Faster than JavaScript physics engine
