使用rust语言+SDL2库写游戏

1. 安装rust

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

2. 设置rust国内源

#当前用户目录下 /linuxidc/.cargo/ 的.cargo 文件夹，进入.cargo 当前目录，在当前目下创建 config 文件
source.crates-io]
registry = "https://github.com/rust-lang/crates.io-index"
replace-with = 'ustc'
[source.ustc]
registry = "git://mirrors.ustc.edu.cn/crates.io-index"

3. 安装SDL库

dnf install SDL2
dnf install SDL2-devel
dnf install SDL2_image-devel
dnf install SDL2_gfx-devel
dnf install SDL2_mixer-devel
dnf install SDL2_ttf-devel

4. 创建rust项目

cargo new testSDL
cd testSDL
编辑cargo.toml，加入sdl2依赖
[dongfeng@localhost testSDL]$ cat Cargo.toml 
[package]
name = "testsdl"
version = "0.1.0"
authors = ["dongfeng <workerwork@qq.com>"]
edition = "2018"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
sdl2 = "0.34"

vim src/main.rs

[dongfeng@localhost testSDL]$ cat src/main.rs 
//extern crate sdl2; 

use sdl2::pixels::Color;
use sdl2::event::Event;
use sdl2::keyboard::Keycode;
use std::time::Duration;
 
pub fn main() {
    let sdl_context = sdl2::init().unwrap();
    let video_subsystem = sdl_context.video().unwrap();
 
    let window = video_subsystem.window("rust-sdl2 demo", 800, 600)
        .position_centered()
        .build()
        .unwrap();
 
    let mut canvas = window.into_canvas().build().unwrap();
 
    canvas.set_draw_color(Color::RGB(0, 255, 255));
    canvas.clear();
    canvas.present();
    let mut event_pump = sdl_context.event_pump().unwrap();
    let mut i = 0;
    'running: loop {
        i = (i + 1) % 255;
        canvas.set_draw_color(Color::RGB(i, 64, 255 - i));
        canvas.clear();
        for event in event_pump.poll_iter() {
            match event {
                Event::Quit {..} |
                Event::KeyDown { keycode: Some(Keycode::Escape), .. } => {
                    break 'running
                },
                _ => {}
            }
        }
        // The rest of the game loop goes here...

        canvas.present();
        ::std::thread::sleep(Duration::new(0, 1_000_000_000u32 / 60));
    }
}

5. 运行项目

cargo run --release
