我一直在編碼我libgdx應用程序(僅適用於臺式機)的同時,並通過部分決定清理代碼部分iv'e得到了一個問題後,我似乎無法來解決自己..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搜索了一會兒後,我想通是在this線程 在
提到我的錯誤的另一個問題可能是你會過早實例化一個SpriteBatch(或其他內部使用SpriteBatch的東西)(在堆棧跟蹤中看起來有點像這樣)。
但作爲答案提到
相反,建立在你的遊戲的創建/顯示方法,這樣的事情。
我似乎無法理解當libgdx初始化並準備使用,並在那裏把我GameUtils.init()方法,以確保libgdx初始化
我的代碼如下:(我有取出的e-相關方法)

new LwjglApplication(dungeonLife, config);
}
}
幫助是大大appriciated! :D
似乎在調用gameUtils.init()之前生成一個新的box2d世界可以解決問題,原因是某種原因 – kw7
