macroquad
macroquad
is a simple and easy to use game library for Rust programming language, heavily inspired by raylib.
macroquad
attempts to avoid any Rust-specific programming concepts like lifetimes/borrowing, making it very friendly for Rust beginners. See the docs.
Features
- Same code for all supported platforms, no platform dependent defines required
- Efficient 2D rendering with automatic geometry batching
- Minimal amount of dependencies: build after
cargo clean
takes only 16s on x230(~6years old laptop) - Immediate mode UI library included
- Single command deploy for both WASM and Android build instructions
Supported platforms
- PC: Windows/Linux/MacOs
- HTML5
- Android
- IOS
Build instructions
Setting up a macroquad project
Macroquad is a normal rust dependency, therefore an empty macroquad project may be created with:
# Create empty cargo project
Add macroquad as a dependency to Cargo.toml:
[]
= "0.3"
Put some macroquad code in src/main.rs
:
use *;
async
And to run it natively:
For more examples take a look on Macroquad examples folder
linux
# ubuntu system dependencies
windows
On windows both MSVC and GNU target are supported, no additional dependencies required.
Also cross-compilation to windows from linux is supported:
wasm
This will produce .wasm file in target/debug/wasm32-unknown-unknown/CRATENAME.wasm
or in target/release/wasm32-unknown-unknown/CRATENAME.wasm
if built with --release
.
And then use the following .html to load it:
<!-- Minified and statically hosted version of https://github.com/not-fl3/macroquad/blob/master/js/mq_js_bundle.js -->
<!-- Your compiled wasm file -->

async/await
While macroquad attempts to use as few Rust-specific concepts as possible, .await
in all examples looks a bit scary.
Rust's async/await
is used to solve just one problem - cross platform main loop organization.
The problem: on WASM and android it's not really easy to organize the main loop like this:
fn main() {
// do some initialization
// start main loop
loop {
// handle input
// update logic
// draw frame
}
}
It is fixable on Android with threads, but on web there is not way to "pause" and "resume" WASM execution, so no WASM code should block ever. While that loop is blocking for the entire game execution! The C++ solution for that problem: https://kripken.github.io/blog/wasm/2019/07/16/asyncify.html
But in Rust we have async/await. Rust's futures
is basically a continuations - future
's stack may be store into a variable to later pause/resume execution of future's code.
async/await in macroquad is used without any external dependencies - no runtime, executor or even futures-rs are involved. It's just a way to preserve main
's stack on WASM and keep the code cross platform without any WASM-specific main loop.
