Java Libgdx项目在android上崩溃

java android libgdx

Java Libgdx项目在android上崩溃,java,android,libgdx,Java,Android,Libgdx,因此，我的LibGDX项目在桌面和安卓系统上都运行得很好，但当我实现一个衡量玩家得分的浮动时，游戏将在安卓系统上崩溃。这个想法是每次屏幕向上滚动时分数都会降低，向下滚动时分数会增加。我正在使用gesturedetector控制器进行滚动。以下是主要代码： public class WorldScreen implements Screen{ private Texture bgCity; private Texture bgLoop; private Texture hud; public

因此，我的LibGDX项目在桌面和安卓系统上都运行得很好，但当我实现一个衡量玩家得分的浮动时，游戏将在安卓系统上崩溃。这个想法是每次屏幕向上滚动时分数都会降低，向下滚动时分数会增加。我正在使用gesturedetector控制器进行滚动。以下是主要代码：
