2048

最近2048非常热门，所以我用C#在移动端自己做了一个wp的2048来玩玩一下。

2048其实是一个很简单的小游戏，在实现过程中主要是要实现移动整合。唯一的难点就是怎么判断移动一下然后整合。我采取的是逐个判断然后逐行判断的形式。代码如下：

 private void OneMove(MoveDict dict)
        {
            bool needGetNext1 = false, needGetNext2 = false, needGetNext3 = false, needGetNext4 = false;
            switch (dict)
            {
                case MoveDict.Up:
                    score += MoveLine(textblocks[13], textblocks[9], textblocks[5], textblocks[1], out needGetNext1) + MoveLine(textblocks[14], textblocks[10], textblocks[6], textblocks[2], out needGetNext2) + MoveLine(textblocks[15], textblocks[11], textblocks[7], textblocks[3], out needGetNext3) + MoveLine(textblocks[16], textblocks[12], textblocks[8], textblocks[4], out needGetNext4);
                    break;
                case MoveDict.Down:
                    score += MoveLine(textblocks[1], textblocks[5], textblocks[9], textblocks[13], out needGetNext1) + MoveLine(textblocks[2], textblocks[6], textblocks[10], textblocks[14], out needGetNext2) + MoveLine(textblocks[3], textblocks[7], textblocks[11], textblocks[15], out needGetNext3) + MoveLine(textblocks[4], textblocks[8], textblocks[12], textblocks[16], out needGetNext4);
                    break;
                case MoveDict.Right:
                    score += MoveLine(textblocks[1], textblocks[2], textblocks[3], textblocks[4], out needGetNext1) + MoveLine(textblocks[5], textblocks[6], textblocks[7], textblocks[8], out needGetNext2) + MoveLine(textblocks[9], textblocks[10], textblocks[11], textblocks[12], out needGetNext3) + MoveLine(textblocks[13], textblocks[14], textblocks[15], textblocks[16], out needGetNext4);
                    break;
                case MoveDict.Left:
                    score += MoveLine(textblocks[4], textblocks[3], textblocks[2], textblocks[1], out needGetNext1) + MoveLine(textblocks[8], textblocks[7], textblocks[6], textblocks[5], out needGetNext2) + MoveLine(textblocks[12], textblocks[11], textblocks[10], textblocks[9], out needGetNext3) + MoveLine(textblocks[16], textblocks[15], textblocks[14], textblocks[13], out needGetNext4);
                    break;
            }
            textBlock_Score.Text = score.ToString();  //显示总分
            if (needGetNext1 || needGetNext2 || needGetNext3 || needGetNext4)
            {
                getNext();//取下一个方块
            }
            else
            {
                if (!CanMove())
                {
                    MessageBox.Show("Game Over!");
                }
            }
        }

然后就是行移动：

private int MoveLine(TextBlock t1, TextBlock t2, TextBlock t3, TextBlock t4, out bool canGetCube)
        {
            canGetCube = false;
            int score1 = 0;
            if (t1.Text.Equals("") && t2.Text.Equals("") && t3.Text.Equals("") && t4.Text.Equals(""))
                return 0;
            if ((t4.Text.Equals("") && (!t1.Text.Equals("") || !t2.Text.Equals("") || !t3.Text.Equals(""))) ||
                (t3.Text.Equals("") && (!t1.Text.Equals("") ||!t2.Text.Equals(""))) ||
                (t2.Text.Equals("") && !t1.Text.Equals(""))
                )
                canGetCube = true;
            TextBlock[] textb = { t1,t2,t3,t4 };
            int[] num = new int[4];
            for (int i = 0; i < 4; i++)
            {
                num[i] = 0;
            }
            for (int j = 0; j < 4; j++)
            {
                if (!textb[j].Text.Equals(""))
                    num[j] = Convert.ToInt32(textb[j].Text.ToString());
            }
            int[] over = new int[4];
            int count = 0;
            for (int i = 0; i < 4; i++)
                over[i] = 0;//去除0之后的方块
            for (int i = 0; i < 4; i++)
                if (num[i] != 0)
                {
                    over[count] = num[i];
                    count++;
                }
           
            for (int i = 0; i < 4 - count; i++)
                textb[i].Text = "";

            for (int i = 0; i < count; i++)
                {
                    textb[i + textb.Length - count].Text = over[i].ToString();
                }
            //先移动
            for (int i = 0; i < 4; i++)
            {
                num[i] = 0;
            }
            for (int j = 0; j < 4; j++)
            {
                if (!textb[j].Text.Equals(""))
                    num[j] = Convert.ToInt32(textb[j].Text.ToString());
            }//将移动好的数冲洗排好
            if (num[2] != 0)//如果等于0，说明该行只有一个非0的数，则不需要再移动和累加分值了。
            {
                if (num[3] == num[2])
                {
                    score1 += 2 * num[2];
                    int a = 2 * num[3];
                    textb[3].Text =a.ToString();
                    canGetCube = true;
                    if (num[1] == num[0])
                    {
                        score1 += 2 * num[1];
                        int b = 2 * num[1];
                        if (b == 0)
                        {
                            textb[0].Text = "";
                            textb[1].Text = "";
                            textb[2].Text = "";
                        }
                        else
                        {
                            canGetCube = true;
                            textb[2].Text = b.ToString();
                            textb[1].Text = "";
                            textb[0].Text = "";
                        }
                    }
                    else
                    {
                        textb[2].Text = textb[1].Text;
                        textb[1].Text = textb[0].Text; ;
                        textb[0].Text = "";
                    }
                }
                else
                {
                    if (num[2] == num[1])
                    {
                        score1 += 2 * num[2];
                        int c = 2 * num[2];
                        if (c == 0)
                        {
                            textb[2].Text = "";
                            textb[1].Text = "";
                            textb[0].Text = "";
                        }
                        else
                        {
                            textb[2].Text = c.ToString();
                            canGetCube = true;
                            textb[1].Text = textb[0].Text;
                            textb[0].Text = "";
                        }
                    }
                    else
                    {
                        if (num[1] == num[0])
                        {
                            score1 += 2 * num[1];
                            int d = 2 * num[1];
                            if (d == 0)
                            {
                                textb[1].Text = "";
                                textb[1].Text = "";
                            }
                            else
                            {
                                textb[1].Text = d.ToString();
                                canGetCube = true;
                                textb[0].Text = "";
                            }
                        }
                    }
                }
            }
            return score1;
        }

其实就是逐个判断然后处理。

最后效果如下：
