我已经使用Python 3.5制作了平台游戏，并且已经进入了第二级。
当您触摸蓝色区域（由E表示）时，我想进入第二级。现在，蓝色区域退出代码，只是要确保已触发触发器。
我创建了第二个放置在数组中的内容。
这是我的代码：

我尝试复制for row in level1:并更改exit函数以更改变量，但是它不起作用。
有人可以帮忙吗？
答案 0 :(得分：2)
好，我知道了。这是代码，它的工作原理是基本上将平台和实体重新初始化为所需的值（与级别相对应，也添加了更多级别，设置了级别变量，然后说出
levelNum == 3:
buildLevel(level3)
否则，更有效的方法是将放到列表中，并将级别num设置为0 同样，这里也有完整的代码，如果您没有通过第三级，那么如果您获得“通过”第二级，则可能无法正常工作，因此您可能只想说些祝贺或其他内容即可。
