java实现2048小游戏（java实现2048小游戏破解版）

直接看效果：

主要难点就在于执行上下左右的逻辑：

 /*向上操作*/
    public void pushUp() {
        System.out.println("push up........");
        for (int y = 0; y < 4; y++) {

                int flag = 0;//判断标志
                if (gameBoard[x][y] != 0) {
                    int value = gameBoard[x][y];
                    int X = x - 1;/*X为前一行*/
                    while ((X >= 0) && gameBoard[X][y] == 0) {
                        X--;
                        flag = 1;
                    }
                    if (X == -1) {/*前面所有行都为0，直接赋值给第一行*/
                        gameBoard[0][y] = value;
                        gameBoard[x][y] = 0;
                    } else if (gameBoard[X][y] != value) {/*flag为0，证明前一行不都为0，并且与该行值不相等，不做操作*/
                        if (flag == 1) {/*中间有1或2行空行，因此将该行的下一行赋值为value*/
                            gameBoard[X + 1][y] = value;
                            gameBoard[x][y] = 0;
