How to reset function second() when I start my program?

portarul23

I do have 2 questions about this second() function. First, I have a program that runs for some seconds, than stops. When i try to run it again, the function second() is still keeping its value. The second question is how do i print seconds only one time. So my console will look like that 1 2 3 4 5.. etc.?

• Function second() matches OS's system clock: https://Processing.org/reference/second_.html
• It got nothing to do w/ how many seconds after sketch has started.
• For that we use millis(): https://Processing.org/reference/millis_.html

That is grate. So i can change from milis to seconds dividing it by 1000, so the first question is answered, but what about the second one? I still have no ideea how can I print only once, 1, than 2, than 3.. Btw, thanks a lot for millis() function.

The good and old timer example:

PFont font;
String time = "000";
int initialTime;
int interval = 1000;//one second
color bg = color (255);



void setup()
{
  size(300, 300);
  font = createFont("Arial", 30);
  background(255);
  fill(0);
  initialTime = millis();
    frameRate(30);// changed framerate to exemplify

}

void draw()
{
  background(bg);
  if (millis() - initialTime > interval)
  {
    time = nf(int(millis()/1000), 3);
    initialTime = millis();
   bg = color (random(255), random(100), random(255));
  }

  text(time, width/2, height/2);


}

That's a basic one...

It might be basic, but I am still new at this program. Thank you a lot for your offered time. It will help me a lot in future.
