How to slow down Random value

[Dan Ebberts]

Try this:

rate = 1/5; // once every 5 seconds
posterizeTime(rate);
x = gaussRandom(50,60);
y = x;
[x,y]

Thank you for your prompt reply but it didn’t seem to work. 😛

Is there a way you can modify Random() expression in similar way as wiggle();??

[Dan Ebberts]

Hmmm… what version of AE are you running?

Try this instead:

period = 5; // every 5 seconds

seed = Math.floor(time/period);
seedRandom(seed,true);
x = gaussRandom(50,60);
y = x;
[x,y]

I’m running AE 6.5..the only thing about the previous script is it makes it just freezes the frame for the time specififed in the script and changes random value suddenly but not gradually. let me try your suggestion.

[Michal]

hmm same thing..it changes value at 0—5—10 etc.. which is fine
however in between those times the scale does not change. Any idea?? Does it work for you??

[Dan Ebberts]

Ah OK – I didn’t pick up that you wanted it to ramp from one value to the next. Try this:

period = 5; // every 5 seconds

seed = Math.floor(time/period);
seedRandom(seed,true);
xNow = gaussRandom(50,60);
seedRandom(seed+1,true);
xNext = gaussRandom(50,60);
x = linear(time,seed*period,(seed+1)*period,xNow,xNext);
y = x;
[x,y]
