Unity经验之谈
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<sting>转为sting，比for循环快多了
void Awake()
{
List<string> list = new List<string>();
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
