Mc.gotoandplay (Math.random () *>>0);

View Code

Math.random () *10 takes a random number with a decimal within 10.
the >>0 function removes the number after the decimal point, so Math.random () *10>>0 gets a random integer within 10

if (i&1) {}

View Code

I&1 means to judge whether I is an odd number or an even number.
Odd 2 binary last one 1, i&1=1 true
Even 2 binary last one 0, i&1=0 fake

var New Array ();  for (var i:int=0; i<; A.push (i++)) {//...}

View Code

After this loop executes, the value of the A array is 0,1,2,3,4,5,6,7,8,9

var temp:number=Mousex;stage.addeventlistener (mouseevent.mouse_move,movehandler); function Movehandler (e:mouseevent):void  {var d:number= (-temp+ (temp=mousex));}

View Code

Get mouse Move distance D
Use the mouse to drag the form or drag the game on the mouse
The code can be changed completely to

mouse.hide (); var temp:number=Mousex;stage.addeventlistener (mouseevent.mouse_move,movehandler); function Movehandler (e:mouseevent):void  {var d:number= (-temp+ (temp=+ = D; E.updateafterevent ();}

Alternative

So spritemouse this movie clip becomes a mouse

function fn1 () {Trace ("1");} function fn2 () {Trace ("2");} ([Fn1,fn2][math.random ()*2>>0]) ();

View Code

This is a random execute function command.

var a:int=3; if (a>0&& (Trace ("A is positivenumber"),a&1)Trace (  "A is positive oddnumber");

View Code

First Execute a>0 True
Execute trace again ("A is positive number")
Finally judge A is not an odd number
The comma expression here is executed from left to right
Mainly used to determine if there are any statements executed.

var a:int=+; var b:int=-; if ((a^b) >0| | (b*=-1,a>)) trace (b);

View Code

Again a comma expression
A^b =-7
B*=-1 b=12
A>10
Output b=12
