Does anybody know how to create a countdown timer from 15 to 0 using a class?

maryjuarez · March 2017

I want the timer to be a class and then call the class inside my main code.

This is just a timer I made in main code, I'm not sure if that will help make a class.

PFont font;
String time = "0:16";
int t;
int interval = 16;

void setup() {

  size(300, 300);
  font = createFont("AdobeHeitiStd-Regular", 30);
  background(255);
  fill(9);
}


void draw() {

  background(255);

  t = interval-int(millis()/1000);
  time = nf(t, 3);

  if (t == 0) {
    println("GAME OVER");
    interval +=16;
  }

  textFont(font);
  text(time, width/2, height/2);
}

...and, if you are interested in complex timers as opposed to simple ones, there are two timer libraries on the Processing Libraries page under Utilities: https://processing.org/reference/libraries/#utilities

CountdownTimer
TimedEvents

When you create your new timer object, what arguments do you want to give it? The amount of time to run, or the time when it should stop...? What should your timer object do when the countdown stops?
