我一直在编码我libgdx应用程序（仅适用于台式机）的同时，并通过部分决定清理代码部分iv'e得到了一个问题后，我似乎无法来解决自己..libgdx尚未初始化
例外：
Exception in thread "LWJGL Application" com.badlogic.gdx.utils.GdxRuntimeException: java.lang.UnsatisfiedLinkError: com.badlogic.gdx.physics.box2d.PolygonShape.newPolygonShape()J

google搜索了一会儿后，我想通是在this线程 在
提到我的错误的另一个问题可能是你会过早实例化一个SpriteBatch（或其他内部使用SpriteBatch的东西）（在堆栈跟踪中看起来有点像这样）。
但作为答案提到
相反，建立在你的游戏的创建/显示方法，这样的事情。
我似乎无法理解当libgdx初始化并准备使用，并在那里把我GameUtils.init（）方法，以确保libgdx初始化
我的代码如下：（我有取出的e-相关方法）
应用类

DungeonLife dungeonLife = new DungeonLife();
new LwjglApplication(dungeonLife, config);
}
}
帮助是大大appriciated！ ：D
似乎在调用gameUtils.init（）之前生成一个新的box2d世界可以解决问题，原因是某种原因 – kw7
