因此，我创建了一个非常简单的平台游戏，我希望平台随机生成，以便每个游戏都是独一无二的。但是，我不确定如何完美地做到这一点。我设法得到了一些实际上在屏幕上生成随机矩形的工作代码，但我不确定如何制作，以便“角色”能够在它们上面移动，并且不会经过或不经过。这是我迄今为止所做的一切代码。现在它并不漂亮，但当我知道一切正常时，我会把它整理好。在此先感谢您的帮助:)生成随机矩形
P.S.我也注释掉相关的随机长方形的东西，因为他们完全填满屏幕，我看不出这是怎么回事：P

看看内置[几何API]（http://docs.oracle.com/javase/tutorial/2d/geometry/index.html）它具有允许您绘制和检查collesions的功能.. – MadProgrammer
请创建一个[简短，自包含的正确示例]（http://sscce.org/）。这是一个问题太多的代码，没有人会阅读所有这些。即使我有时间，根据原则，我拒绝读取调用其类'aa'，'ab'，'ac'，'ad'的代码（除非我的老板强迫我）。 – Amadan
@Amadan抱歉，这是我第一次在这里发表帖子。我删除了前两个班，因为它们与问题无关。我只叫他们aa，ab等，因为我不能想到更好的名字给他们哈哈。 –
