generating unique elements in an array

[jzevin]

I'm trying to generate an array with 3 random elements
the problem is I want each element to have a unique value

here is what I have so far but it seems to be an infinite loop. Is there an easier way or can this code be fixed

winList = new Array();
//
for (i = 0; i < 3; i++) {
ran = random(3)+1;
winList[i] = ran;
trace (winList);
for (j = 0; j < i; j++) {
do {
ran = random(3)+1;
winList[i] = ran;
} while (winList[j] = winlist[i-1]);
}
}

Do you mean

2, 1, 3 is ok
1, 3, 2 is ok
3, 1, 2 is ok, but
1, 1, 2 is not
3, 3, 1 is not etc?

If so, here's what I do:

source = new Array(1, 2, 3);
target = new Array();
while (target.length<3) {
rand = random(source.length);
target.push(source.splice(rand, 1));
}

PS You could have picked that little trick up in FAST file #3 (see link below)
