【花雕动手做】基于 Kitronik 可编程开发板之星际战舰

Kitronik ARCADE 是一款由英国教育科技公司 Kitronik 精心打造的可编程游戏机开发板，专为编程教学与创客实践而设计。该设备原生支持微软的 MakeCode Arcade 平台，用户可通过图形化或 JavaScript 编程方式，轻松创建、下载并运行复古风格的街机游戏。

它集成了彩色 LCD 显示屏、方向控制键、功能按键、蜂鸣器和震动马达等交互组件，提供完整的游戏输入输出体验。无论是初学者进行编程启蒙，还是创客群体开发交互式作品，Kitronik ARCADE 都能作为理想的硬件载体，助力创意实现。

凭借其开源友好、易于上手、兼容性强等特点，该开发板广泛应用于中小学编程课程、创客工作坊、游戏开发教学以及个人项目原型设计，深受教育者与技术爱好者的喜爱。

作为学习、练习与尝试，这里创建一个星际战舰的小游戏。

ARCADE MakeCode 星际战舰游戏代码解读
这是一个太空射击游戏的代码，玩家控制一艘星际战舰在太空中移动，并发射随机方向的激光。让我为您详细解读这个游戏的代码结构和功能：

游戏概述
这是一个简单的太空射击游戏，玩家控制一艘星际战舰在屏幕内移动，按下A键发射向随机方向飞行的激光。游戏背景是绚丽的星空。

核心代码解析
1. 射击控制
python

def on_a_pressed():

    global projectile

    projectile = sprites.create_projectile_from_sprite(img("""激光图像"""),

        mySprite,  # 从玩家飞船发射

        randint(-120, 120),  # 随机水平速度（-120到120）

        randint(120, -120))  # 随机垂直速度（120到-120）
复制代码

按下A键时，从玩家飞船创建一个激光抛射物

激光使用ASCII艺术定义外观

激光以随机方向发射：

水平速度：-120到120之间的随机值

垂直速度：120到-120之间的随机值（包含向上和向下）

2. 玩家飞船创建
python

mySprite = sprites.create(img("""飞船图像"""), SpriteKind.player)

controller.move_sprite(mySprite)  # 允许玩家控制移动

mySprite.set_stay_in_screen(True)  # 限制在屏幕内
复制代码

创建玩家飞船，使用ASCII艺术定义外观

启用控制器移动（默认速度）

限制飞船不能离开屏幕边界

3. 游戏场景设置
python

scene.set_background_image(img("""星空背景"""))
复制代码

设置绚丽的星空背景，使用ASCII艺术创建

背景包含各种颜色的星云、星星和太空景观

游戏机制总结
控制方式：使用方向键移动飞船

射击机制：按下A键发射随机方向的激光

移动限制：飞船不能离开屏幕

视觉体验：绚丽的星空背景增强游戏沉浸感

技术特点
随机化设计：激光发射方向完全随机，增加游戏不确定性

自由移动：玩家可以自由控制飞船在屏幕内移动

视觉丰富：使用复杂的ASCII艺术创建精美的飞船和背景

简单核心：游戏机制简单但具有重复可玩性

图形编程参考实验程序

通过模拟器，调试与模拟运行
