如何让玩家通过pygame的第一关

问题描述

我的游戏已经创建，但是我真的很想再添加一个级别，如何为赛车游戏创建另一个级别？我已经为其创建了第一个关卡，但是我想在赛车到达终点线的尽头时添加另一个关卡。我怎样才能做到这一点？预先谢谢您！

解决方法

使您当前拥有的级别1的所有内容（轨道，音轨等）作为级别1的一类。并为Level2创建类似的内容。然后在游戏循环中，初始化级别（目前可以是一个全局变量，可以从中查找，但建议将其中具有这样封装的属性的Game对象封装在其中）在开始新游戏时设为Level1。然后，当玩家完成关卡1（通过在关卡1类中进行检查后，可以在不同关卡上使用不同的完成参数），将关卡更改为关卡2。

您需要记住哪些不同的事情？根据当前选定的级别渲染级别。深入研究this answer。
