如何用Java控制台玩2048

昨天晚上咸的，想自己做个2048试试，折腾到半夜算是有点成果，分享下，由于搞的太晚也没来得及加注释，最后也没有优化重构，就简单看下思路吧

先看个拼图的小游戏消化下

import java.io.IOException;

public class Puzzle {
	static final int X = 3;
	static final int Y = 3;
	static int tar[][] = new int[X][Y];
	static int BX,BY;
	static int step = 0;

	static void init(){
		/*正常排序插入*/
		int index = 0;
		for (int i = 0; i < X; i++) {
			for (int j = 0; j < Y; j++) {
				tar[i][j] = index++;
			}
		}
		/*打乱排序*/
		for (int i = 0; i < tar.length; i++) {
			for (int j = 0; j < tar[i].length; j++) {
				int temp = tar[i][j];
				int randomX, randomY;
				randomX = (int) (Math.random()*X);
				randomY = (int) (Math.random()*tar[randomX].length);
				tar[i][j] = tar[randomX][randomY];
				tar[randomX][randomY] = temp;
			}
		}
	}

	static void outPrint(){
		boolean isok = true;

		for (int i = 0; i < X; i++) {
			for (int j = 0; j < Y; j++) {
				if(tar[i][j] == 0){
					System.out.print("	[囧]");
					BX = i;BY = j;
				}else{
					if(tar[i][j]!=(i*(Y) + j + 1)){
						isok = false;
					}
					System.out.print("	["+(tar[i][j]<10?" "+tar[i][j]:tar[i][j])+"]");
				}
			}
			System.out.println();
		}
		if(isok){
			System.out.println("恭喜获胜！步数： "+step);
		}else{
			System.out.println("go on! 步数： "+step);
		}
	}

	static void change(int dir){
		switch (dir) {
		case 115://S 下
			if(BX != 0){
				tar[BX][BY] = tar[BX-1][BY];
				tar[BX-1][BY] = 0;
				BX--;
				step++;
				outPrint();
			}
			break;
		case 100://D 右
			if(BY != 0){
				tar[BX][BY] = tar[BX][BY-1];
				tar[BX][BY-1] = 0;
				BY--;
				step++;
				outPrint();
			}
			break;
		case 119://W 上
			if(BX != X-1){
				tar[BX][BY] = tar[BX+1][BY];
				tar[BX+1][BY] = 0;
				BX++;
				step++;
				outPrint();
			}
			break;
		case 97://A 左
			if(BY != Y-1){
				tar[BX][BY] = tar[BX][BY+1];
				tar[BX][BY+1] = 0;
				BY++;
				step++;
				outPrint();
			}
			break;

		default:
			break;
		}
	}

	public static void main(String[] args) throws IOException {

		init();
		outPrint();
		while(true){
			int read = System.in.read();
			change(read);
		}
	}
}

按W S A D 为上下左右，其实就是一个二维数组，来按方向改变相邻的位置

下面这个是2048的游戏，跟上面差不多，就是要相邻的加在一起，然后去掉空格的（值为0),看看吧，欢迎拍砖

有兴趣的可以重构下，有些方法应该是可以抽出来公用的
