ive made a countdown for a game but i am having trouble finding where to place it.

i start the game with a start button and then i want the countdown to begin 3 2 1 (as i have created) then after the 3 2 1 the game should start. but thats the function im having trouble with.

thank you if anyone can point me in the right direction :)

(countdown code below)

int sec=0;

void setup(){
size(320,600);
smooth();
}

void draw(){
background(0);

sec=second();
for(int lop=0;lop<5;lop++){
    if(sec>10)sec=second()-(10*lop);

}

////seconds////
if(sec==3){
    rect(240,80,48,160);
    rect(240,288,48,160);
}
if(sec==2){
    rect(80,32,160,48);
    rect(80,240,160,48);
    rect(32,288,48,160);
    rect(80,448,160,48);
    rect(240,80,48,160);
}
if(sec==1){
    rect(80,32,160,48);
    rect(80,240,160,48);
    rect(80,448,160,48);
    rect(240,80,48,160);
    rect(240,288,48,160);

}
}

hmm i can't see where the counting is being done, but if you want a timer you can use the java Timer functionality.

this particular timer will fire off its event every second (1000ms = 1s),
so if you want a countdown you could just do

import javax.swing.Timer;
import java.awt.event.*;
int sec = 0;
Timer clock = new Timer(1000, new ActionListener() {
public void actionPerformed(ActionEvent e) {
++sec;
}
});
void setup(){
size(320,600);
smooth();
// will start the timer
clock.start();
}
void draw() {
switch(sec) {
case 1:
rect(80,32,160,48);
rect(80,240,160,48);
rect(80,448,160,48);
rect(240,80,48,160);
rect(240,288,48,160);
break;
case 2:
rect(80,32,160,48);
rect(80,240,160,48);
rect(32,288,48,160);
rect(80,448,160,48);
rect(240,80,48,160);
break;
case 3:
rect(240,80,48,160);
rect(240,288,48,160);
default:
break;
}
}

this will do what you want it to, however, i wouldn't keep the switch in the draw loop just because it's messy, you could however create a timer that only fires 3 times and then turns itself off though.

Timer countdown = new Timer(1000, new ActionListener() {
public void actionPerformed(ActionEvent e) {
++sec;
switch(sec) {
case 1:
break;
case 2:
break;
case 3:
break;
default:
countdown.stop();
break;
}
});

cant guarantee the code will work if copy pasted, but the idea is right, and it should work with 1-2 spelling fixes / whatnot.

int msec, sec;
boolean start;
 
void setup(){
  size(320,600);
  smooth();
}
 
void draw(){
  background(0);
 
  if(!start) {
    sec = floor((millis()-msec)*.001);
//above:
//current cumulative time in thousands of a second subtract the
//time the countdown started to start from "now" divide by 1000
//and drop the decimal part
    if(sec == 4) start = true;
  } else {
//do stuff here when the coundown finishes    
    ellipse(random(width), random(height), 100, 100);
  }
 
 
  ////seconds////
  if(sec == 3){ //after three seconds one second remains ...
    rect(240,80,48,160);
    rect(240,288,48,160);
  }
  if(sec == 2){
    rect(80,32,160,48);

  msec = millis();
  start = false;
}
