如何避免libGDX游戏项目中的“静态”

问题描述

我目前正在重新设计我的代码，因为它难以阅读，而不是真正的OOP。 我正在开发一个libGDX游戏，因此代码是用Java编写的。 目前，我正在使用一些静态方法和变量。 我想避免它们，但我不知道如何。 在我的游戏项目中，我使用了几个不同的类。 有实际的游戏屏幕，暂停屏幕和创建类，当我第一次打开屏幕时会创建资产。 游戏画面中有一个int用于检测游戏当前是在运行还是暂停。 但我不知道如何在不使其变为静态的情况下更改此变量。

谢谢你的每一个答案:)！ 干杯，Joshflux

编辑：这是GameScreen和Create类的代码。 这可能有点令人困惑：/。
