像素引擎游戏内控制台扩展

这个crate是pixel_engine的扩展。它提供了一个游戏内控制台，可以接收命令（字符串形式）。它还提供了一个简单的方法通过日志API将消息打印到控制台（crate中也包含宏）

此扩展旨在与未来的扩展完全兼容

extern crate pixel_engine;
extern crate pixel_engine_console;

struct Game;
impl pixel_engine::Game for Game {
    fn create(engine: &mut Engine) -> Result<Self, Box<dyn std::error::Error>> {
        Ok(Self)
    }

    fn update(&mut self, engine: &mut Engine) -> Result<bool, Box<dyn std::error::Error>> {
        // Opens the console
        engine.open_console(
            Keycodes::Escape, // The key used to close the console
            false,            // Does the update function will be called when the console is opened
        );

        cinfo!("Hello console !"); // Print a info message into the console
    }
}

impl ConsoleGame for Game {
    fn receive_console_input(&mut self, engine: &mut Engine, input: String) {
        // process the input
        // for example the shlex crate allow you to split the input into arguments like a shell
    }
}

fn main() {
    pixel_engine::start::<Game>("Console Example", (500, 500), 2);
}
