unity3d中javasciprt脚本参考

1.关键字(keyword)

 as booleanbreak bytecase catchchar classcontinue default
double else enum extends finally float for function if import
in instanceof int long new null private protectedpublic return

short staticsuper switchthis throwtry typeofvar 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:

TypeDescriptionExamplesbyte8-bit signed integer.var n : sbyte = -2;short16-bit signed integer.var n : short = -2;int32-bit signed integer.var n : int = 2;long64-bit signed integer.var n : long = 2;byte8-bit unsigned integer.var n : byte = 2;ushort16-bit unsigned integer.var n : ushort = 2;uint32-bit unsigned integer.var n : uint = 2;ulong64-bit unsigned integer.var n : ulong = 2;floatSingle-precision floating point value.var f : float = 2.0;doubleDouble-precision floating point value.var f : double = 2.0;booleanRepresents a true / false value.var b : boolean = true;charA unicode character.var c : char = "c"[0];StringRepresents 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
}
