JAVA super 马里奥让马里奥掉进缺口

Question

我的问题很简单:我很难找到一个解决方案，让马里奥在间隙(空旷的空间，没有地面)上行走时摔倒。如果您知道执行此操作的有效方法，请告诉我。另外，如果您不明白，请告诉我是否需要我对代码的解释，谢谢!

Answer 1

首先，请阅读this 。我们希望帮助您，但您至少不应该让我们为难。

无论如何，我们现在来回答你的问题。

好吧，从我从你的代码中读到的内容来看，我可以看到map[]是地面。我假设 1 是一 block 地面，0 是一个间隙。如果是这样，我将尝试继续我的解释。

我要做的是将屏幕划分为与map[]数组中的任何元素一样多的列。例如，如果 map 数组中有 20 个元素，则程序应将屏幕分为 20 列。数组中的每个元素对应于屏幕上的一列。

然后，应该检查 Mario 的 x 值，程序应该检查他所在的部分。如果他的部分在 map 数组中为 0，则他应该跌倒。如果 map 数组的值为 1，则他在地面上。
