Adding a frame rate to random() function
I’m using the random(12) function to power my animation.
It’s working great, but I want to make it go slower.Without using wiggler how would I update values every 5 frames?
I thought I could do something like my code below, but I think it needs refinement.
t = Math.round(time*30)%5;if(t=0){
r=random(12);
}else{
r=0;

Try this:
t = Math.floor(timeToFrames(time) / 5);
seedRandom(t + index, true);
random(12);
In this case the seedRandom() function is ‘timeless’ so that calls to random() won’t generate new values over time, but the seed that we’re providing to seedRandom() is based on a modified frame count. When the modified frame count updates every 5 frames it should generate a new seed for the random() function. I’m also adding the index of the layer to the seed so that if you have several layers they won’t all return the same ‘random’ value.
Just checked this in CS6 and it works great, the “+ index” portion of the seed isn’t even necessary as I suppose each call to the seedRandom() function generates a different random progression (at least in CS6, I’ve left it just in case this is different in previous versions).

Thanks Darby,
This simple code works better than I imagined.
