Tetra is a simple 2D game framework written in Rust. It uses SDL2 for event handling and OpenGL 3.2+ for rendering.
Note that Tetra is still extremely early in development! It may/will have bugs and missing features. That said, you're welcome to give it a go and let me know what you think :)
To add Tetra to your project, add the following line to your Cargo.toml file:
tetra = "0.2"
Tetra currently requires Rust 1.31 or higher.
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:
```rust use tetra::graphics::{self, Color}; use tetra::{Context, ContextBuilder, State};
struct GameState;
impl State for GameState { fn draw(&mut self, ctx: &mut Context, _dt: f64) -> tetra::Result { // Cornflour 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(&mut GameState) } ```
You can see this example in action by running cargo run --example hello_world.
The full list of examples is available here.
As mentioned above, Tetra is fairly early in development, so there's likely to be bugs/flaky docs/general weirdness. Please feel free to open an issue/PR if you find something, or leave a question in the Gitter chat.
