extern crate pixel_engine as px;
use px::traits::*;
fn main() {
    px::launch(async move { // the launch function is just a utility function to block on async, even on the web
        let game = px::EngineWrapper::new("Lines".to_owned(), (25, 25, 20));
        let mut start = (0, 0);
        let mut end = (5i32, 5i32);
        game.run(move |game: &mut engine::Engine| {
            // Drawing to the screen:
            game.clear([0, 0, 0].into());
            game.draw_line(
                start,
                end,
                [1.0, 1.0, 1.0].into(),
            );
            game.draw(start, [0, 255, 0].into());
            game.draw(end, [255, 0, 0].into());
            
            some_failible_function()?; // You can return errors, but it will crash the program and print the error message
            // Handling inputs
            game.get_key(px::inputs::Keycodes::Escape).any() {
                return Ok(false); // Returning Ok(false) is the only way to do a clean shutdown
            }
            Ok(true) // Continue to next frame
        });
    });
}

这是line示例的简化代码。有些示例实际上并不很有用（如input.rs）。它们在这里是为了确保我不会破坏任何东西。
