Changing colors within a for loop

killthepixelnow

Hell guys, is there a way to fill all the circles with different color? I've tried a few solutions but the colors keep blinking, they don't stay fixed as I want:

int circleW=15;
int circleH=15;
int theSpace=circleW/3;
int redColor = int(random(10,255));
int greenColor= int(random(50,255));
int blueColor = int(random(200,255));

void setup() {
  size(600, 400);
  frameRate(30);
  smooth();
  noStroke();
  ellipseMode(CORNER);
}

void draw() {
  background(0);

  for (int i = 0; i < width-circleW/2; i = i+(circleW+theSpace)) {
    fill(redColor,greenColor,blueColor);
    ellipse(i, height/2, circleW, circleH);
  }

}

add noLoop(); to the end of setup()

this stops draw from being executed again and again. the flashing you're seeing is the circles being continually redrawn using a new random fill colour.

if you want each circle to be a different colour then move lines 4-6 after line 19

GoToLoop

add noLoop(); to the end of setup().

Just a lil' correction. noLoop() can be issued anywhere.
Processing invokes draw() at least once, no matter what! >-)

When writing to newbies, it is better to be precise, otherwise we can get exotic code... It is a bit like the message "hit any key", provoking perplexity ("which key?!").

Although I have seen, when I wrote "at the end of xxx()", the line after the closing brace of this function...

Thanks guys, you rock.

GoToLoop

When I want to use it, I place noLoop() right after size()! I like to clump related canvas settings together! =:)
