java实现gif播放（闪烁问题未解决）

                    e.printStackTrace();
                }
            }
        }
    }

    public static void main(String[] args) {
        MyGameFrame me=new MyGameFrame();
        me.launchFrame();
    }
}

import java.awt.Image;
import java.awt.image.BufferedImage;
import java.io.IOException;
import java.net.URL;

import javax.imageio.ImageIO;

public class GameUtil {
private GameUtil() {
    
}

public static Image getImage(String path) {
    // TODO Auto-generated method stub
    BufferedImage image=null;
    try {
        URL url=GameUtil.class.getClassLoader().getResource(path);
        image=ImageIO.read(url);
    } catch (IOException e) {
        // TODO: handle exception
        e.printStackTrace();
    }
    return image;
}
}

原理：

循环播放六十几帧png，用drawImage画出来

 线程PaintThread控制每一帧停留时间然后重画

而png的命名是数字递增的

 

png文件

 

效果

 

png文件链接
