Python编写小游戏——天降鸿福

sunnychen · 发表于 2024-4-9 11:16

通过Python 编写小游戏，让学习变得有趣。通过练习逐步掌握 Python 编程的基本概念和技能，也能给学习者带来成就感和乐趣。
在开发游戏时，主要用到Pygame库，用于处理游戏中的图形、音频、事件等。
天降鸿福是一种有趣的反应游戏，主要用到Python的游戏循环、随机数生成和碰撞测试。
玩家需要移动鼠标控制一个可左右移动的盘子，在屏幕上接住不同颜色的球来得分。游戏中有三种颜色的球，分别是红色、绿色和蓝色，每种颜色的球都有不同的分值。
但需要注意的是，红色的球是负分球，接到红色球会减少分数同时盘子长度减少，当盘子长度减少到0时，游戏结束。
玩家需要尽可能地接住绿色和蓝色球来得分，同时避免接到红色球。
