Random Number Expressions
Hi, I am trying to create a matrix rain type effect. I am using a custom particle i am creating driven by the random() expression function to generate random integers between 0 and 9 and it also has the posterized function to keep it from changing every frame. Is there an expression i can use to ensure that each time the integer changes it doesn’t end up being the same integer as the previous. These are the expressions i have in my source text as of now:
Thanks for any help
posterizeTime(10);
s=random(9);
Math.round(s) -

This expression should give you a different digit every three frames:
holdFrames = 3;
seedRandom(index,true);
f = timeToFrames();
seg = Math.floor(f/holdFrames);
r = Math.floor(random(10));
for (i = 0; i < seg; i++) r = (r + Math.floor(random(1,10)))%10;
