Tetra is a simple 2D game framework written in Rust. It uses SDL2 for event handling and OpenGL 3.2+ for rendering.
- XNA/MonoGame-inspired API
- Efficient 2D rendering, with draw call batching by default
- Easy input handling, via polling or events, with support for gamepads
- Deterministic game loop by default, Ã la Fix Your Timestep
- Common building blocks built-in, such as:
- Font rendering
- Cameras
- Screen scaling
To add Tetra to your project, add the following line to your Cargo.toml file:
tetra = "0.4"You will also need to install the SDL2 native libraries - full details are provided in the documentation.
To get a simple window displayed on screen, the following code can be used:
use tetra::graphics::{self, Color};
use tetra::{Context, ContextBuilder, State};
struct GameState;
impl State for GameState {
fn draw(&mut self, ctx: &mut Context) -> tetra::Result {
// Cornflower blue, as is tradition
graphics::clear(ctx, Color::rgb(0.392, 0.584, 0.929));
Ok(())
}
}
fn main() -> tetra::Result {
ContextBuilder::new("Hello, world!", 1280, 720)
.build()?
.run(|_| Ok(GameState))
}You can see this example in action by running cargo run --example hello_world.
The full list of examples is available here.
Tetra is fairly early in development, so you might run into bugs/flaky docs/general weirdness. Please feel free to open an issue/PR if you find something! You can also contact me via Twitter, the Rust Game Development Discord, or the #games-and-graphics channel on the Rust Community Discord.
