使用Rust开发小游戏完成过程

本文是对使用 Rust 开发一个微型游戏【已完结】

cargo new flappy

在Cargo.toml的[dependencies]下方增加:

bracket-lib = "~0.8.7"

main.rs中:

use bracket_lib::prelude::*;
struct State {}
impl GameState for State {
    fn tick(&mut self, ctx: &mut BTerm) {
        ctx.cls();
        ctx.print(1, 1, "Hello,Bracket Terminal!");
    }
}
fn main() -> BError {
    let context: BTerm = BTermBuilder::simple80x50()
        .with_title("爽哥做游戏--Flappy Dragon")
        .build()?;
    main_loop(context, State {})
}

cargo run后,可以看到

use bracket_lib::prelude::*;
// 游戏3种模式(菜单,游戏中,结束)
enum GameMode {
    Menu,
    Playing,
    End,
}
struct State {
    mode: GameMode,

impl State {
    fn new() -> Self {
        State {
            mode: GameMode::Menu,
        }
    }
    fn play(&mut self, ctx: &mut BTerm) {
        //TODO
        self.mode = GameMode::End;
    }
    fn restart(&mut self) {
        self.mode = GameMode::Playing;
    }
    fn main_menu(&mut self, ctx: &mut BTerm) {
        ctx.cls();
        ctx.print_centered(5, "欢迎来到游戏~");
        ctx.print_centered(8, "Press P key to start Game");
        ctx.print_centered(9, "Press Q to quit Game");
        if let Some(key) = ctx.key {
            match key {
                VirtualKeyCode::P => self.restart(),
                VirtualKeyCode::Q => ctx.quitting = true,
                _ => {}
            }
            {}
        }
    }
    fn dead(&mut self, ctx: &mut BTerm) {
        ctx.cls();
        ctx.print_centered(5, "你挂了..");
        ctx.print_centered(8, "按P键 再来一局");
        ctx.print_centered(9, "按Q键 退出游戏");
        if let Some(key) = ctx.key {
            match key {
                VirtualKeyCode::P => self.restart(),
                VirtualKeyCode::Q => ctx.quitting = true,
                _ => {}
            }
            {}
        }
    }
}
impl GameState for State {
    fn tick(&mut self, ctx: &mut BTerm) {
        match self.mode {
            GameMode::Menu => self.main_menu(ctx),
            GameMode::End => self.dead(ctx),
            GameMode::Playing => self.play(ctx),
        }
        // ctx.cls();
        // ctx.print(1, 1, "Hello,Bracket Terminal!");
    }
}
fn main() -> BError {
    let context: BTerm = BTermBuilder::simple80x50()
        .with_title("爽哥做游戏--Flappy Dragon")
        .build()?;
    main_loop(context, State::new())
}
