TakWolf's Game Engine (tge)

A lightweight cross-platform 2D game framework written in pure Rust and based on OpenGL 3.3+.

Inspired by LÖVE.

Tge is currently in a very early stage of development. The API may be changed. Until the version to 0.1.0.

Features

• 2D only and use pixel unit.
• Hardware-accelerated rendering base on OpenGL.
• Automatically process rendering batching.
• Dynamic font rendering with text layout.
• Interface for handling keyboard, mouse, touch, touchpad and gamepad.
• Audio play. (TODO)

Non goals

• 3D.
• Visual editor.

The following does not contain, but can easily work with other crates:

• Entity Component System (ECS).
• Physics engines and collision detection.
• Network.

Usage

Add the dependency line to your Cargo.toml file:

toml [dependencies] tge = "0.0.3"

To release performance, also add the following configs:

toml [profile.dev] opt-level = 3

Then create a basic template. Here is the minimal example that will create a window:

```rust use tge::prelude::*;

struct App {}

impl App { fn new(_: &mut Engine) -> GameResult { // load assets Ok(Self {}) } }

impl Game for App { fn update(&mut self, _: &mut Engine) -> GameResult { // handle logic Ok(()) }

fn render(&mut self, engine: &mut Engine) -> GameResult {
    engine.graphics().clear(Color::BLUE);
    // draw sprites
    Ok(())
}

}

fn main() -> GameResult { let mut engine = EngineBuilder::new() .windowconfig(WindowConfig::new() .title("My Game") .innersize((800.0, 600.0))) .build()?; let mut app = App::new(&mut engine)?; engine.run(&mut app) } ```

That is!

You can also see the examples/ directory to learn other examples.

Performance

See the example bunny_mark and sprites.

TODO

The following is working in progress:

• blend
• program uniform
• screenshot
• virtual assets path
• assets load async
• audio
• document
