JAVA学习，写的一个2048小游戏

       很久之前写的一个2048小游戏，最开始没考虑动画，动画后来加上去的，导致代码有点乱。

       到2048分就赢，想多加点把数组扩大就行。

 

截图：

 

 

4个类：

Start--------------入口

MainFrame-----主类

BlockData-------动画相关

Direct------------方向

 

 

代码：

类Start：

import java.io.IOException;
import javax.imageio.ImageIO;
import javax.swing.UIManager;

public class Start {

    public static void main(String[] args) {
        // 使用Windows的界面风格
        try {
            UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");
        } catch (Exception e) {
            e.printStackTrace();
        }
        MainFrame mf = new MainFrame();
        mf.setVisible(true);
        try {
            mf.getGraphics().drawImage(ImageIO.read(Start.class.getResource("logo.png")), 10, 35, 295, 370, null);
        } catch (IOException e) {e.printStackTrace();}
    }

}
