如何让玩家在pygame中通过第一关

Question

我的游戏已经创建，但我真的很想添加第二个关卡，我如何才能继续为我的赛车游戏创建另一个关卡？我已经为它创建了第一个关卡，但我想在我的车到达终点线时再添加一个关卡。我该怎么做？提前谢谢你

Answer 1

将您当前拥有的所有级别1（曲目、配乐等）作为级别1的一个类。并为Level2创建类似的。然后在游戏循环中，在开始一个新游戏时，将level初始化为Level1（目前它可以是一个全局变量，但建议在其中封装一个游戏对象，其属性如下）。当玩家完成等级1时（在等级1类中处理检查，这样你可以在不同等级上有不同的完成参数），将等级更改为等级2

你需要记住哪些不同的事情？基于当前选定的级别渲染级别。查看this answer了解更多信息
