Question

我的问题是，我是否以某种方式在我的程序中实现了多线程，因为在我的程序中，在包含2个图像的Controller类中，当单击图像时，控件应该运行到paraopen或paraopen2（取决于哪个图像单击）但真正发生的是paraopen和paraopen2方法一个接一个地点击两个图像后同时执行。我认为应该发生的事情是，如果打开paraopen（通过点击其各自的图像），控制应该进入paraopen并且在完成paraopen后应该初始化然后到paraopen2（通过点击其repsective图像）。方法（初始化，paraopen和paraopen2）运行就好像在三个不同的线程中运行，这是我最初想要的（确定有很多重复的代码，但它有效）。

有人可以帮助我理解paraopen和paraopen2这两个函数是如何同时工作的。播放器类是我的主类，控制器类包含我想要理解的代码。

先谢谢。

这是我的玩家类（主要类）
