how to reset after ### frames (in a loop)
Apr 26th, 2010, 1:39pm  
I would like to know how I can reset after 100 frames in a loop.
What I have written now doesn't repeat the act ... it comes only once white, after 100 frames, but I wish that it also resets after 200, 300, 400, ... frames. How do I do that?

Code:

float[][] a=new float[40][2];

int  nbrPasses;

void setup(){
  size(900,600);
  noStroke();
  fill(0,10);
  background(255,0);


}

void draw(){
  a[0][0]=mouseX;
  a[0][1]=mouseY;
  for(int i=1;i<40;i++){
    stroke(99,0,i*3,i*4);
    line(a[i][0],a[i][1],a[i][0]+=(a[i-1][0]-a[i][0])/i,a[i][1]+=(a[i-1][1]-a[i][1])/i);
  }

// IT CONCERNS THIS BIT:
   ++nbrPasses;
  if (nbrPasses == 100)
  {
    println("100");
    save("snapshot.png");
    fill(255);
    rect(0, 0, width, height);
}
}


Thanks for the help!

the obvious way is to set nbrPasses = 0 when it gets to 100 so that it just starts again.

or use the modulo operator in your test - (nbrPasses % 100) == 0

Note that frameCount variable is the same as your nbrPasses and is automatically incremented on each call of draw().
