unity3d中javasciprt脚本参考

1.关键字(keyword)

 as boolean break byte case catch char class continue default
double else enum extends finally float for function if import
in instanceof int long new null private protected public return

short static super switch this throw try typeof var while

2.变量

变量可以是public或者private的，public变量可以被外界访问，private变量只能在当前脚本中直接访问；如果不加修饰则默认是public的

利用@HideInInspector指令可以不让public变量

如:

@HideInInspector

var someVar : int = 0;

内置的变量类型如下表:

Type	Description	Example
sbyte	8-bit signed integer.	var n : sbyte = -2;
short	16-bit signed integer.	var n : short = -2;
int	32-bit signed integer.	var n : int = 2;
long	64-bit signed integer.	var n : long = 2;
byte	8-bit unsigned integer.	var n : byte = 2;
ushort	16-bit unsigned integer.	var n : ushort = 2;
uint	32-bit unsigned integer.	var n : uint = 2;
ulong	64-bit unsigned integer.	var n : ulong = 2;
float	Single-precision floating point value.	var f : float = 2.0;
double	Double-precision floating point value.	var f : double = 2.0;
boolean	Represents a true / false value.	var b : boolean = true;
char	A unicode character.	var c : char = "c"[0];
String	Represents text as a series of Unicode characters.	var s : String = "Hello, world";

3.控制语句

if(xxx){}

if(xxx){} else{}

if(xxx){} else if(yyy) else{}

for(var i : int = 0; i < 100; i++)

{

// do something
}

while(xxx)

{
}

do{

}while(xxx);

4.异常

try

{

//do something

}catch( e : System.Exception )

{

//except
}
