Actionscript:
-
for (var i:int = 0; i<10; i++){
-
// randomly set a variable to -1 or positive 1
-
trace(int(Math.random()*2) - 1 | 1);
-
}
-
-
/* outputs something like this
-
1
-
1
-
-1
-
1
-
-1
-
-1
-
1
-
1
-
-1
-
-1

The past few days I found myself using this one-liner a few times. Just a quick way to randomly get -1 or 1.
I was brainstorming today and wrote a weird/bad inline version of an old post:
var rand:Number = [-3, 2, 1, 1, 1, 0.5][int(Math.random() * 6)];
I need to install a related posts plugin for WordPress - would be nice if this post were related to my old post about Tausworthe random seeds.
Been posting medium/large snippets and snippets the relate to QuickBox2D - so today I figured I'd get back to basics...
