Unity3D实现简易五子棋源码
本文实例为大家分享了Unity3d简易五子棋源码，供大家参考，具体内容如下
Unity3d部分
对C#源码进行了改写简化：

public GameObject RightTop;
public GameObject LeftBottom;
public GameObject RightBottom;

Vector3 RTPos;

float gridHeight = 1; //棋盘网格高度
float minGridDis; //网格宽和高中较小的一个
Vector2[,] chessPos; //存储棋盘上所有可以落子的位置
int[,] chessState; //存储棋盘位置上的落子状态

turn chessTurn; //落子顺序
public Texture2D white; //白棋子
public Texture2D black; //黑棋子
public Texture2D blackWin; //白子获胜提示图
public Texture2D whiteWin; //黑子获胜提示图

chessState = new int[17, 16];/*原来定义是new int[15, 15]，这里将原来数组chessState上、下和右边各加一排数据，
也就相当于在棋盘的上、下和右边各填加一排隐形的棋道。原因后面解释*/

//计算锚点位置

}
}

因为上、下和右边各多加了一排，要空出来，chessPos的i行对应chessState的i+1行*/
{
//根据下棋顺序确定落子颜色
chessState[i + 1, j] = chessTurn == turn.black ? 1 : -1;//同理
//落子成功，更换下棋顺序

//改写result函数
/*解释：C语言中，这样的表达式：chessState[i]&&chessState[i+1]&&chessState[i+2]&&chessState[i+3]&&chessState[i+4]，如果
* chessState[i]为False,则不管B是真是假或者是异常都不会运行，利用这一点，在chessState的右边、上边和下边各加一行为0的数据，
* 这样在判断连续五个棋子的状态时，就不用担心chessState数组的索引值超出范围。例如：chessState[i+4]的索引值i+4刚好超出范围，
* 通过在原来数组chessState的上、下和右边个添加一排为0的数，这样chessState[i+3]==0，于是就可以避免引起异常，从而简化代码*/
