Math.random returns always the same number Extendscript
Hi, I got this function:
function randomIntInRange(min, max) {
now = new Date();
seed = now.getMilliseconds();
return Math.floor(Math.random(seed) * (max - min + 1) + min);
}
I used it for a long time with no problems(on mac and windows). But since yesterday, is behaving in a strange way. I use it on a loop, and is returning me always the same number when I run the script. I tryed to use the red dot on the Toolkit to see what happens, clickiing on the play button every loop, but then, it works properly and returns diferent numbers.
Anybody can figure out what is happening?PD: The same script with no changes worked the past days.

It’s a known synchronization issue that was introduced in CC 2014 (I think). Adobe’s solution was to create a new generateRandomNumber() function. If there’s any chance your script could be used in an older version of AE, you’ll need to test for version number before using it. This is how I do it:
function getRandom(){
return parseFloat(app.version) > 13.6 ? generateRandomNumber() : Math.random();
}
Then just use getRandom() wherever you would use Math.random().
BTW, as far as I know, Math.random() doesn’t take any parameters, so I don’t think your seed code makes any difference.
