I'm trying to make an animation of a pair of eyes' pupils swelling up. Eventually I want it to look like they're getting so surprised that they fill up the rest of the eye and fill the entire screen with black. first I want to be able to control the growth so it stops at a certain point. I can't make it work. I've gone back through the blue processing book and im beating my head against a wall. I have no idea why except that I can't use an integer and float...which doesn't make sense.

can someone explain what I'm screwing up, please?
thank you


void setup (){
 noStroke ();
 smooth();
 noLoop();
 size (400, 400);
 noStroke ();
 smooth();
 noLoop();
 int y = 140.0;
 int x = 210.0;
 int c = 60.0;
}
 
void draw(){

 frameRate (30);
 stroke (55);
 ellipse (200, 100, 100, 100);
 ellipse (130, 150, 100, 100);
 fill (#000000);
 ellipse (x, x-100, c, c);
 ellipse (y, y+20, c, c);
 if (x > 170){
   x -= 1;
   if (y > 90){
     y -= 1;
     if (c < 100){
       c += 1;
     }
   }
 }
}

Something like this ?

Code:

 int c = 60; 
 int d = 1;
 
void setup ()
{
  size (400, 400);
   noStroke ();
   smooth();
   
   frameRate (30);
}
 
void draw()
{
 stroke (55);
 fill(255);
 ellipse (200, 100, 100, 100);
  fill (0);
 ellipse (200, 140-c/2, c, c);
 
 fill (255);
 ellipse (130, 150, 100, 100);
  fill (0);
 ellipse (130, 190-c/2, c, c);
 
 if(c < 30) d = 1;
 else if(c > 90) d = -1;
 
 c += d;
 
}

Perhaps you looked at wrong examples I sampled a couple of Processing official examples and they set it in setup(). Which makes sense: the frame rate has rarely to change during a sketch, no need to set it repeatedly.
It is true for lot of settings that you don't plan to change during the sketch, like smooth(), textFont(), or even strokeWidth() (but you might have reasons to change the last two, just pointing out often sketches set it over and over without real need).

When you need a fractional quantity... In general, coordinates, loop number, number of objects, etc. are integer. Random numbers, some quantities, angles, etc. can be float.
