A method of generating a random number that is not repeated (with a shaded instance)

Random | Repeats the number 0 to 99 and does not repeat.
Applies when you do multiple random squares to shade a picture and play the music randomly while playing the animation, but not repeat.
Method One:

Oldtime=gettimer ();
My_array=new Array ();
n=100;
for (Var i=0;i<n;i++) {
My_array[i]=i;
}
for (Var i=0;i<n;i++) {
var tmp1=random (n);
var tmp2=my_array[i];
MY_ARRAY[I]=MY_ARRAY[TMP1];
MY_ARRAY[TMP1]=TMP2;
}
Trace (My_array);
Trace (Gettimer ()-oldtime);//program run time
//----------------------------------------------------------

--------------Method Two-------------------------------------

N=gettimer ();
Array.prototype.randomize = function () {
This.sort (function (A, b) {return random (2) >0? 1:-1;});
}
var myarray = new Array ();
for (Var i=0;i<1000;i++) {
Myarray[i]=i;
}
Myarray.randomize ();
Trace (myarray);
Trace (Gettimer ()-N);

Method Three:

var num_arr:array = new Array ();
var j = 0;
var judge = 0;
do {
var temp_num = Math.Round (Math.random () *100);
for (var i = 0; i<num_arr.length; i++) {
var temp_n = num_arr[i];
if (Temp_num = = temp_n) {
Judge = 1;
Break
} else {
Judge = 0;
}
}
if (judge = = 0) {
Num_arr.push (Temp_num);
j + +;
_root["T" +j].text = Temp_num;
}
while (j<100);
Trace (Num_arr);

Production process: Build two layers, each put a picture, where the top of the picture definition instance name: PIC_MC
Then draw a rectangle, convert it to MC, define the ID name as box, and write the As on the frame:
Creatmask ();
Set up a cover picture
Newnum ();
Generate random numbers
var i =-1;
var n = 0;
_root.onenterframe = function () {
i++;
if (i<300) {
Eval ("_root.m1_mc.box" +my_array[n]). Removemovieclip ();
Remove Square
n++;
}
if (i>=400 && i<700) {
m = my_array[i-400];
_root.m1_mc.attachmovie ("box", "box" +m, m+10, {_x:int (M/15) *20, _y:m%15*20});
Load box
}
if (i>800) {
i = 0;
n = 0;
}
};
//-------------------------------------
function Creatmask () {
_root.createemptymovieclip ("M1_MC", 1);
m1_mc._x = 0;
mc_mc._y = 0;
for (var i = 0; i<300; i++) {
_root.m1_mc.attachmovie ("box", "box" +i, i+10, {_x:int (I/15) *20, _y:i%15*20});
}
Pic_mc.setmask (M1_MC);
}
function Newnum () {
My_array = new Array ();
n = 300;
for (var i = 0; i<n; i++) {
My_array[i] = i;
}
for (var i = 0; i<n; i++) {
var tmp1 = random (n);
var tmp2 = my_array[i];
My_array[i] = My_array[tmp1];
MY_ARRAY[TMP1] = TMP2;
}

There is a difference between the production method and the box element in the square into the MC, and then edit the MC, do some movement on the above deformation.
Newnum ();
Generate random numbers
_root.createemptymovieclip ("M1_MC", 1);
m1_mc._x = 0;
mc_mc._y = 0;
Pic_mc.setmask (M1_MC);
for (var i = 0; i<300; i++) {
_root.m1_mc.attachmovie ("box", "box" +i, i+100, {_x:int (I/15) *20, _y:i%15*20});
}
