1、全屏与非全屏之间的切换

   if (Input.GetMouseButtonDown(1))  
    {  
        Screen.fullScreen = !Screen.fullScreen;  
    }

2、Camera适应所有的分辨率

　　　　void Start () {
Camera.main.aspect = 16 / 10f;
　}

3、字符串分割时，一定要注意空格，空格在日志中不好看出来。

        string a = "a,b,c ";  
        string\[\] aa = a.Split(',');  
        string value=aa\[2\];//最后会得到"c "  
        //最好的方式是多加一个","  
        string b = "a,b,c,";  
        string\[\] bb = b.Split(',');  
        string value1 = bb\[2\];//最后会得到"c"

4、win10和win7 进程名称不同

win10 的进程名是PlayerSettings里的Product Name，

而比较坑的是在win7系统下，同一个程序，进程名居然是.exe的名字，例如你的unity 打包的exe名字叫做 Test.exe,

而Product Name名字叫 MyTest，则win10的进程名为 MyTest，而win7的进程名却TM是 Test ，坑死。

5、unity在调用外部的库时（如：dll, jar,so），传递的参数一定要注意C#的垃圾回收机制。

如果传入外部的参数，如果被垃圾回收掉GC.Collect()，可能会导致程序崩溃，报非法访问内存的错误。

解决的办法就是将参数设置为静态的全局变量，因为 static 是不会被GC掉的。

如：在PC端，会报如下错误

6、unity动画中的SetTrigger方法只有用过以后才置回，如果你将一个动画片段设置SetTrigger而一直没有走到该动画，则SetTrigger的状态会一直为ture，直到播放到该动画片段，SetTrigger才置回原来的状态即false。

7、快速的将sting[ ]或者List转为sting，比for循环快多了

void Awake()
{
List list = new List();
list.Add("1");
list.Add("2");
list.Add("3");

    string value = string.Join("-",list);  
    Debug.Log(value);  
}

输出：

8、Unity 中3D物体添加button响应，在Camera上添加Physics Raycaster即可
