unity3d 入门——实现井字棋

代码部分是用c#实现的，作为有过c,c++基础的程序员，c#上手的感觉还可以，也没有到什么高级的特性。

作为3d游戏编程课程的第一个作业，还有师兄的博客的参考，整体难度并不大。

实现中主要用到了

行为对象属性中的:

OnGui()//渲染处理GUI事件，没一帧调用一次

GUI标签

GUI.Label() //在屏幕上创建一个文本或者纹理标签。

GUI.Button()//创建一个单次按下按钮。用户点击按钮事件立即触发。当用户点击按钮的时候返回true。

以下是整体实现的代码。如果有bug欢迎指出哟~

using System.Collections.Generic;
using UnityEngine;

public class mybutton : MonoBehaviour {
//显示棋盘内容
private string[] info = new string [9];
//记录棋盘的状态，state 0代表没有按下，1代表X按下, 2代表O按下
private int[] state = new int[9];
//1代表X的回合，0代表O的回合
private int turn =0;
private string result="";
