我一直在尝试为基本的Java游戏创建一个功能按钮，但每当我点击屏幕时（字面上我在参数内外的任何地方），我的游戏中都没有功能。我试图弄清楚我的冲突在哪里鼠标事件不起作用。我有几乎所有的双重和三重检查，我找不到问题。我包含了Game Class和Menu类，但如果需要其他类，我会发布它们。我也知道代码很可能非常草率和不合适，但我只是在学习并尝试自学一些基础知识。
问题是＆＃34; STATE＆＃34;我创建的枚举？
问题可以在boolean mouseOver中的某个地方吗？
我非常困惑，不明白我到底搞砸了。我希望能够拥有游戏所需的功能。很抱歉，如果这是一个非常基本的问题，或者代码很糟糕，我会尽力提供帮助。
