Rustic Mountain Core

这是一个用于模拟2015年游戏竞赛发布的Celeste Classic游戏物理和图形的Rust库

安装

cargo add rustic-mountain-core

基本用法（例如，创建端口）

fn main(){
    // consts are not included in the core library. see examples here: https://github.com/CoolElectronics/rustic-mountain/blob/main/standalone/src/consts.rs
    let mut engine = Celeste::new(
        consts::MAPDATA.into(),
        consts::SPRITES.into(),
        consts::FLAGS.into(),
        consts::FONTATLAS.into(),
    );
    let pallete: [(u8, u8, u8); 16] = [
        (0, 0, 0),
        (29, 43, 83),
        (126, 37, 83),
        (0, 135, 81),
        (171, 82, 54),
        (95, 87, 79),
        (194, 195, 199),
        (255, 241, 232),
        (255, 0, 77),
        (255, 163, 0),
        (255, 236, 85),
        (0, 228, 54),
        (41, 173, 255),
        (131, 118, 156),
        (255, 119, 168),
        (255, 204, 170),
    ];

    loop {
        // advance the game logic
        engine.next_tick();
        // render the screen
        engine.draw();



        // screen buffer is a 128x128 array
        for (i, col) in engine.mem.graphics.iter().enumerate() {
            // look up rgb color from pallete
            let color = pallete[*col as usize];
            let xpixel = i % 128;
            let ypixel = i / 128;

            // do rendering to screen here
        }

                        engine.mem.buttons[0] = is_left_arrow_pressed;
                        engine.mem.buttons[1] = is_right_arrow_pressed;
                        engine.mem.buttons[2] = is_up_arrow_pressed;
                        engine.mem.buttons[3] = is_down_arrow_pressed;
                        engine.mem.buttons[4] = is_jump_pressed;
                        engine.mem.buttons[5] = is_dash_key_pressed;


        // constrain to 30fps
        ::std::thread::sleep(Duration::new(0, 1_000_000_000u32 / 30));
    }
}

高级用法

大多数方法和字段都标记为公开，因此游戏可以被轻松修改和扩展。例如，您可以通过遍历celeste.objects向量来找到玩家位置，创建自己的地图等。我并没有编写文档，只是阅读代码，主要部分只有1k多行
