我的问题非常简单：我很难找到一个解决办法，让马里奥在走上差距（空地，没有地面）时摔倒。如果您知道这样做的有效方法，请告诉我。另外，如果您不理解，请告诉我您是否需要我的代码说明，谢谢！

答案 0 :(得分：0)
首先，请阅读this。我们想帮助你，但至少你不应该让我们更难。
无论如何，现在让我们回答你的问题。
嗯，从我的代码中可以看到，我可以看到map []是基础。我假设1是地块，0是间隙。如果是这样，我会尝试继续解释。
我要做的是将屏幕划分为map []数组中任何元素的列数。例如，如果地图数组中有20个元素，则程序应将屏幕划分为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。如果他的部分在地图数组中有0，他应该摔倒。如果地图数组为1，那么他就在地面上。
