_ java.lang.UnsupportedOperationException：未指定AudioDevice
行：
AudioDevice audioDev = su.getViewer().createAudioDevice();
WrapShooter3D w3d = new WrapShooter3D();
javax.imageio.IIOException: Can't read input file!
{ new Shooter3D(); }
_ Java 3D：音频被禁用
线程“ main”中的com.sun.j3d.utils.image.ImageException异常：
行：
TextureLoader stoneTex = new TextureLoader("images/stone.jpg", null);
Appearance apStone = stoneApp();
GunTurret gun = new GunTurret(startVec);
makeGun(canvas3D);
createSceneGraph(canvas3D);
WrapShooter3D w3d = new WrapShooter3D();
{ new Shooter3D(); }
_原因：javax.imageio.IIOException：无法读取输入文件！
行：
throw new IIOException("Can't read input file!");
最佳答案
TextureLoader stoneTex = new TextureLoader（“ images / stone.jpg”，null）;
尝试用文件的完整路径替换“ images / stone.jpg”。例如。 “ c：\ abc \ efg \ images \ stone.jpg”。
