Pygame开发Wordle游戏遇视频系统未初始化错误求助

核心问题分析 #

1. 视频系统提前关闭：代码中处理QUIT事件时直接调用pygame.quit()，但后续仍执行pygame.display.update()或pygame.event.get()，此时视频系统已关闭，触发报错。
2. 递归重启游戏风险：通过playgame()递归开启新游戏会导致栈溢出，逻辑易混乱。
3. 事件处理逻辑漏洞：嵌套循环的事件处理重复且存在顺序错误（比如删除、回车的判断时机），导致游戏卡在首页。

修复后的代码及关键修改点 #

关键修改说明 #

• 终止后续代码执行：处理QUIT事件时，调用pygame.quit()后直接exit()，避免视频系统关闭后仍执行相关操作。
• 优化事件判断逻辑：将字母判断改为elif避免重复赋值，调整删除、输入、回车的判断顺序，修复逻辑漏洞。
• 增加帧率控制：添加clock.tick(60)降低CPU占用，解决游戏卡顿问题。
• 修复提示文本位置：用get_rect(center)替代固定坐标，适配不同窗口分辨率。
• 避免递归栈溢出：若游戏重启次数较多，建议改用外部主循环控制游戏启停（比如返回布尔值标记是否重启）。
