kontrol Junior Member Offline Posts: 92	controlling the rate of the random object Aug 14th, 2007, 11:04pm   is it possible to change the rate of how often a new number is sent by the random object? i cant use frameRate since it crappity smacks my app as i am dealing with fast moving objects.. Slm

I want to control how often the color of this box changed. void setup(){    size(120,120);  background(0); } void hello(){  fill(int(random(0,255)),int(random(00,255)),int(random(0,255)),100);  rect(10,10,100,100); } void draw(){  hello(); }

JohnG Ex Member	Re: controlling the rate of the random object Reply #3 - Aug 15th, 2007, 4:54pm   There's a couple of ways you can do it: Code: //change it every other frame.. if(frameCount%2 == 0) { fill(.....); } rect(...); or... Code: int last=0; //... void hello() { //change it every 1/10th of a second. if(millis()>last+100) { last=millis(); fill(...); } rect(...); }

JohnG Ex Member	Re: controlling the rate of the random object Reply #5 - Aug 15th, 2007, 5:37pm   the rect will still draw and move as smoothly as before, it'll just only change colour every now and then. you see only the fill command is within the if(...) block, so only that is slowed down, all the rest of the code runs at the same speed as previously.
