但是，当我运行我的游戏时，我几乎完成写作游戏，Android Studio抱怨出现以下错误：Error:(103, 8) Gradle: error: illegal start of expressionError:(103, 15) Gradle: error: illegal start of expressionError:(103, 26) Gradle: error: ';' expectedError:(103, 43) Gradle: error: ';' expected。Android Studio LibGDX游戏问题
下面是我的GameScreen类的代码：

可能有人给我帮助上修复这些错误？我将不胜感激！
您声明函数中的函数。这不是有效的java，我不知道你期望它做什么。 – njzk2
也阅读你的错误，它会告诉你哪一行是问题所在。 – njzk2
