macroquad
macroquad is a simple and easy to use game library for Rust programming language, heavily inspired by raylib.
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 cleantakes only 16s on x230(~6 years old laptop). - Immediate mode UI library included.
- Single command deploy for both WASM and Android.
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
cargo init --bin
Add macroquad as a dependency to Cargo.toml:
[dependencies]
macroquad = "0.4"
Put some macroquad code in src/main.rs:
use macroquad::prelude::*;
#[macroquad::main("BasicShapes")]
async fn main() {
loop {
clear_background(RED);
draw_line(40.0, 40.0, 100.0, 200.0, 15.0, BLUE);
draw_rectangle(screen_width() / 2.0 - 60.0, 100.0, 120.0, 60.0, GREEN);
draw_circle(screen_width() - 30.0, screen_height() - 30.0, 15.0, YELLOW);
draw_text("IT WORKS!", 20.0, 20.0, 30.0, DARKGRAY);
next_frame().await
}
}
And to run it natively:
cargo run
For more examples take a look at Macroquad examples folder
Linux
# ubuntu system dependencies
apt install pkg-config libx11-dev libxi-dev libgl1-mesa-dev libasound2-dev
# fedora system dependencies
dnf install libX11-devel libXi-devel mesa-libGL-devel alsa-lib-devel
# arch linux system dependencies
pacman -S pkg-config libx11 libxi mesa-libgl alsa-lib
Windows
On windows both MSVC and GNU target are supported, no additional dependencies required.
Also cross-compilation to windows from linux is supported:
rustup target add x86_64-pc-windows-gnu
cargo run --target x86_64-pc-windows-gnu
WASM
rustup target add wasm32-unknown-unknown
cargo build --target wasm32-unknown-unknown
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:
index.html
<html lang="en">
<head>
<meta charset="utf-8">
<title>TITLE</title>
<style>
html,
body,
canvas {
margin: 0px;
padding: 0px;
width: 100%;
height: 100%;
overflow: hidden;
position: absolute;
background: black;
z-index: 0;
}
</style>
</head>
<body>
<canvas id="glcanvas" tabindex='1'></canvas>
<!-- Minified and statically hosted version of https://github.com/not-fl3/macroquad/blob/master/js/mq_js_bundle.js -->
<script src="https://not-fl3.github.io/miniquad-samples/mq_js_bundle.js"></script>
<script>load("CRATENAME.wasm");</script> <!-- Your compiled wasm file -->
</body>
</html>
One of the ways to server static .wasm and .html:
cargo install basic-http-server
basic-http-server .
IOS
To run on the simulator:
mkdir MyGame.app
cargo build --target x86_64-apple-ios --release
cp target/release/mygame MyGame.app
# only if the game have any assets
cp -r assets MyGame.app
cat > MyGame.app/Info.plist << EOF

Tips
Adding the following snippet to your Cargo.toml ensures that all dependencies compile in release even in debug mode. In macroquad, this has the effect of making images load several times faster and your applications much more performant, while keeping compile times miraculously low.[profile.dev.package.'*']

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.
Details
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 are basically continuations - future's stack may be stored into a variable to pause/resume execution of future's code at a later point.
async/await support in macroquad comes without any external dependencies - no runtime, no executors and futures-rs is not 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.
