Optic Engine

A modular Rust game engine composed of independently-compilable sub-crates.

optic-engine is the facade crate — add it to Cargo.toml and enable the features you need. All public items from sub-crates are re-exported.

Feature flags

Feature Crate Description
core optic_core Shared types, math, colours, logging
file optic_file Asset file I/O and cached paths
render optic_render OpenGL 4.6 rendering (EGL, shaders, meshes)
window optic_window Windowing, input, gamepad (winit + gilrs)
minimal optic_loop Game loop + Runtime trait
online optic_online UDP networking

Quick start

[dependencies]
optic-engine = { version = "0.0", features = ["minimal"] }

use optic_engine::{Game, Runtime};

struct App;
impl Runtime for App {
    fn update(&mut self) { /* game logic */ }
}

fn main() {
    Game::new("My Game", (800, 600), App).unwrap().run();
}
