Mochi :dango:

A game engine oriented toward low power mobile linux phones/tablets. It's written in Rust and uses Gtk and Cairo! All drawing is done with an Cairo Context that this library has extended to do some really common graphics operations.

This project is super alpha but usable. If you want to join in, feel free to open up an issue or make a PR!

Example

pong

[dependencies] mochi = "0.0"

```rust init(include_bytes!("game.gresource"));

let imgmochi = imagefromresource("/game/mochi.png"); let imgmochieaten = imagefromresource("/game/mochieaten.png");

rungame(move |window, ctx, pointer, deltatime| { if pointer.isdown() { ctx.drawimagecentered(window.width / 2.0, window.height / 2.0, imgmochieaten); } else { ctx.drawimagecentered(window.width / 2.0, window.height / 2.0, imgmochi); } }); ```

How to build a game

Mochi works off resources put into a Glib resource file. This is pretty simple to do. Just make an xml file that references your images:

xml <?xml version="1.0" encoding="UTF-8"?> <gresources> <gresource prefix="/pong"> <file>ball.png</file> <file>paddle.png</file> </gresource> </gresources>

Build into a gresource file that Glib can understand:

rust glib-compile-resources game.xml

Inline the bytes of the game.gresource into your code during init:

rust init(include_bytes!("game.gresource"));

Now your game has everything it needs in it's binary! The images can be acquired as needed using the resource paths you setup.

rust let img_ball = image_from_resource("/pong/ball.png");
