首先说一下，这个游戏是参加了MIAC第二届的比赛的一个作品，惨败，获得了优胜奖，在这记录整理一下开发的过程吧。
先来几张截图大体了解一下
个人logo界面
游戏菜单界面
游戏加载界面
游戏主界面
分享至新浪微博界面
大体就分这几个界面，接下来会详细介绍，这篇文章主要讲一下菜单界面，关于这个界面，真是要说很多，自我感觉杂乱无章，这个界面结合了eclipse做的一个NFC接口的SDK，起初对NFC是一点不懂，在图书馆借了本《Android传感器高级编程》的书才略知一二，了解后赶紧写了个NFC的SDK，关于这个SDK，技术不精的我愣是搞了好几天，各种吧bug，愁得要死要活的，不过就中还是实现了NFC的感应控制游戏，不知道为什么这样一个技术应用到游戏中也没有伯乐，市场几乎没有这种技术应用到游戏中的，好可惜，那么，这篇文章就写一下这个SDK吧。
我们用到了eclipse，安卓手游嘛，所以跟做安卓app类似了，先建一个工程吧，注意，这里的工程要求比较苛刻，我们必须保证这个包名跟签名与unity最后打包生成的包名签名一致，否则会出现程序已停止，就是根本无法启动，新建工程后，我需要导入unity的类库，
，至于这个库去哪找，我不多说了，在unity的安装的根目录里，不懂得请百度吧，导入之后，我们就可以写NFC底层了，直接贴代码了，代码中有详细注释

大概就这样了，我们还需要在AndroidManifest.xml中添加NFC需要的权限，以及我们需要过滤的自定义NFC标签，

直接在工程中找的，因为后期添加了新浪微博的SDK，需要添加更多的权限，我们后续再说，这个NFC的SDK就已经弄好了，我们导出工程为jar包就好了，下面就是在unity端调用接口了，先写一下接口具体怎么调用，
//////////////////////////////////////////////////////////////////////////////////////////////////////////////
if (reNFC1 == “N”)
{
if (clo)
{
//GUI.skin = GUIskin;
if (GUI.Button(new Rect(Screen.width * 0.36f, Screen.height * 0.6f, Screen.width * 0.24f, Screen.height * 0.13f), “”))//点击确定进入游戏NFC为读取模式，进入游戏
{
music.PlayOneShot(beep1);
using (AndroidJavaClass jc = new AndroidJavaClass(“com.unity3d.player.UnityPlayer”))
{
using (AndroidJavaObject jo = jc.GetStatic<AndroidJavaObject>(“currentActivity”))
{
//调用Android插件中UnityTestActivity中StartActivity0方法，stringToEdit表示它的参数
jo.Call(“StartActivity0”, name1);
}
}
//Application.LoadLevel(“Loading”);
NFC2 = 0;

依旧是比较杂乱，接口的调用都写在界面里了，我们在接下来的文章中继续讲解界面时再给大家贴出详细的代码。
