实现消除

1、Chess.java

package Linkup;

*

*/

public class Chess {

// 图片的 状态 //1.....20

// 0表示消掉

private int status;

public Chess(int status) {

this.status = status;

}

public int getStatus() {

return status;

}

public void setStatus(int status) {

this.status = status;

}

}

2、Param.java

package tools;

import java.awt.Image;

import javax.swing.ImageIcon;

public class Param {

//游戏总行数与总列数

public static int rows=8;

public static int cols=10;

//棋子图标 宽与高

public static int chessWidth =55;

public static int chessHeight=55;

//棋盘到边界的距离

public static int marginWidth = 200-chessWidth;

public static int marginHeight = 100-chessHeight;

//游戏的背景图片

public static Image imageBackground = new ImageIcon("Images/build/back.jpg").getImage();

public static Image[] chessImage = new Image[20];

static {

for (int i = 0; i < chessImage.length; i++) {

chessImage[i] = new ImageIcon("Images/build/" + (i + 1) + ".png").getImage();

import javax.swing.JFrame;

public class LinkUpMainFrame extends JFrame {

MapPanel mapPanel = new MapPanel();

public LinkUpMainFrame() {

this.add(mapPanel);

this.setTitle("连连看");// 设置 标题

this.setSize(1000, 650);// 设置宽高

this.setLocationRelativeTo(null);// 自动适配到屏幕中间

this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);// 设置关闭模式

this.setResizable(false);

this.setVisible(true);// 设置可见

ImageIcon imageIcon = new ImageIcon("Images/Photos/serverstop.gif");

Image image = imageIcon.getImage();

this.setIconImage(image);// 设置连连看窗体图标

}

public static void main(String[] args) {

new LinkUpMainFrame();

}

}

接下来就要开始做进度条，时间限制，如何实现洗牌啦!期待~~
