descriptionA lightweight game framework for making 2D games with minimum friction, inspired by Love2D.



# ggez [![ggez logo](docs/ggez-logo-maroon-full.svg)]( ## What is this? ![Build status]( [![Docs Status](]( [![license](]( [![](]( [![](]( [![Discord chat](]( ggez is a Rust library to create a Good Game Easily. The current version is 0.9.3. More specifically, ggez is a lightweight cross-platform game framework for making 2D games with minimum friction. It aims to implement an API based on (a Rustified version of) the [LÖVE]( game framework. This means it contains basic and portable 2D drawing, sound, resource loading and event handling, but finer details and performance characteristics may be different than LÖVE. ggez is not meant to be everything to everyone, but rather a good base upon which to build. Thus it takes a fairly batteries-included approach without needing a million additions and plugins for everything imaginable, but also does not dictate higher-level functionality such as physics engine or entity component system. Instead the goal is to allow you to use whichever libraries you want to provide these functions, or build your own libraries atop ggez. ### Features * Filesystem abstraction that lets you load resources from folders or zip files * Hardware-accelerated 2D rendering built on the `wgpu` graphics API * Loading and playing .ogg, .wav and .flac files via the `rodio` crate * TTF font rendering with `glyph_brush`. * Interface for handling keyboard and mouse events easily through callbacks * Config file for defining engine and game settings * Easy timing and FPS measurement functions. * Math library integration with `mint`. * Some more advanced graphics options: shaders, instanced draws and render targets ### Non-Features (i.e. things to add from elsewhere if needed) * [Physics]( * Animation (check out [keyframe](; [it works pretty well with ggez]( ([source]( * [GUI]( * [Assets manager]( * [AI]( * [ECS]( * [Networking]( ### Supported platforms * Fully supported: Windows, Linux, MacOS * Not officially supported but might work anyway: Android, iOS, Web For details, see [docs/](docs/ If you want to run ggez (up to 0.7 as of now) on Android, iOS or the web using WebAssembly right now, take a look at [good-web-game]( ### Who's using ggez? Check out the [projects list!](docs/ ### Usage ggez requires rustc >= 1.42 and is distributed on To include it in your project, just add the dependency line to your `Cargo.toml` file: ``` ggez = "0.9.3" ``` ggez consists of three main parts: A `Context` object which contains all the state required to interface with the computer's hardware, an `EventHandler` trait that the user implements to register callbacks for events, and various sub-modules such as `graphics` and `audio` that provide the functionality to actually get stuff done. The general pattern is to create a struct holding your game's data which implements the `EventHandler` trait. Create a new `Context` object with default objects from a `ContextBuilder` or `Conf` object, and then call `event::run()` with the `Context` and an instance of your `EventHandler` to run your game's main loop. See the [API docs]( for full documentation, or the [examples](/examples) directory for a number of commented examples of varying complexity. Most examples show off a single feature of ggez, while `astroblasto` and `snake` are small but complete games. ### Getting started For a quick tutorial on ggez, see the [Hello ggez]( guide in the `docs/` directory. ### Examples See the `examples/` directory in the source. Most examples show off a single feature of ggez, while `astroblasto` is a small but complete Asteroids-like game. To run the examples, just check out the source and execute `cargo run --example` in the root directory: ``` git clone cd ggez cargo run --example 05_astroblasto ``` If this doesn't work, see the [FAQ]( for solutions to common problems. #### Basic Project Template ```rust,no_run use ggez::{Context, ContextBuilder, GameResult}; use ggez::graphics::{self, Color}; use ggez::event::{self, EventHandler}; fn main() { // Make a Context. let (mut ctx, event_loop) = ContextBuilder::new("my_game", "Cool Game Author") .build() .expect("aieee, could not create ggez context!"); // Create an instance of your event handler. // Usually, you should provide it with the Context object to // use when setting your game up. let my_game = MyGame::new(&mut ctx); // Run! event::run(ctx, event_loop, my_game); } struct MyGame { // Your state here... } impl MyGame { pub fn new(_ctx: &mut Context) -> MyGame { // Load/create resources such as images here. MyGame { // ... } } } impl EventHandler for MyGame { fn update(&mut self, _ctx: &mut Context) -> GameResult { // Update code here... Ok(()) } fn draw(&mut self, ctx: &mut Context) -> GameResult { let mut canvas = graphics::Canvas::from_frame(ctx, Color::WHITE); // Draw code here... canvas.finish(ctx) } } ``` ### Implementation details ggez is built upon `winit` for windowing and events, `rodio` for sound, and a 2D drawing engine implemented with `wgpu`. It is entirely thread-safe (though platform constraints mean the event-handling loop and drawing must be done in the main thread), and portable to Windows and Linux. ggez is pure Rust™. ### Help!
