C/C++：实现象棋游戏

• 大体思路
  采用面相过程的设计方式实现，类似于我们平时做的课程设计，实现这样的小游戏无非就是多了图形处理库。这里使用的是acllib图形库。

  设计这种小游戏，首先要从宏观上去认识：象棋，要有棋盘，要有棋子，棋子要移动。
  对于棋盘，十行九列画出即可。
  对于棋子，分黑红两方，按照指定位置画出。
  如何移动棋子，我们有mouseEvent函数。

  初始化棋盘棋子：initmap，initpaint
  利用鼠标实现棋子移动分两步(mouseEvent)：
  第一次点击，记录点击棋子的信息
  第二次点击，将第一次点击记录的棋子信息移动到第二次点击的位置。
  最后在添加亿点细节。

• 首先画棋盘——chessboard（）

• 初始化棋子信息——initmp（）

• 将棋子画到棋盘上——initpaint（）

• 注册鼠标，通过鼠标点击不同位置实现棋子的移动（按照象棋行棋规范）——mouseEvent（int x, int y, int button, int e）x、y为点击位置，button（鼠标左右键与滑轮）、e（点击或抬起）为事件。

• 行棋规范——judge_piece(int x, int y)代表能否从上一步走到x,y处。

此外，实现象棋必然缺不了人机对战。对于人机算法我们可以采用最简单的遍历。每次遍历获取所有人机方棋子能走的地方，然后根据评估函数找出这些步中对人机方来说收益最大的一步。思路很简单，但是想写出走一步看很多步的算法也很难。首先评估函数要尽量具有代表性，这直接决定了人机的棋力；其次需要迭代遍历，这样次数多了时间复杂度就会很高。

这里只写了走一步看一步的人机代码供参考，更深入的可以自行去了解：

1、void Get_All_path()——获取人机所有可能走的方式（将step存入向量v中）

2、int calculate_value()——评估函数

3、void Get_max_way()——得到对人机最有利的那一步（传到prex，prey与nowx，nowy中，即从pre走到now）。

struct step
{
	int x1, y1, x2, y2;
};//从x1，y1走到x2，y2
void Get_All_path()
{
	v.clear();//全局变量
	step temp;
	for (int a = 0; a < 16; a++)
	{
		if (black_chess[a].is == 0)continue;
		prex = black_chess[a].row;
		prey = black_chess[a].col;
		temp.x1 = prex;
		temp.y1 = prey;
		for(int i=0;i<10;i++)
			for (int j = 0; j < 9; j++)
			{
				temp.x2 = i;
				temp.y2 = j;
				if (judge_piece(i, j) == 1&&mp[i][j].color!='B')
				{
					v.push_back(temp);
				}
			}
	}
}
int calculate_value()
{
	int sum1 = 0, sum2 = 0;
	for(int a=0;a<10;a++)
		for (int b = 0; b < 9; b++)
		{
			if (mp[a][b].color == 'B' && mp[a][b].is == 1)
			{
				switch (mp[a][b].index)
				{
				case 0:
					sum1 += 100;
					break;
				case 1:
					sum1 += 50;
					break;
				case 2:
					sum1 += 10;
				case 3:
					sum1 += 10;
					break;
				case 4:
					sum1 += 1500;
					break;
				case 5:
					sum1 += 50;
					break;
				case 6:
					sum1 += 20;
					break;
				default:
					break;
				}
			}
			else if (mp[a][b].color == 'R' && mp[a][b].is == 1)
			{
				switch (mp[a][b].index)
				{
				case 7:
					sum2 += 100;
					break;
				case 8:
					sum2 += 50;
					break;
				case 9:
					sum2 += 10;
				case 10:
					sum2 += 10;
					break;
				case 11:
					sum2 += 1500;
					break;
				case 12:
					sum2 += 50;
					break;
				case 13:
					sum2 += 20;
					break;
				default:
					break;

	return sum1 - sum2;
