I want a countdown timer only when the mouse is on the bottom left rectangle the timer counts down and if you are not in that part it doesnt count down. Thank you in advance.

some big game framework you got already,  
and good posting format,  
BUT  
-a- without the files and fonts can not test,  
-b- and getting a full screen of a failed game  
and can not see console msg.  
is very annoying

— as soon i got it finally running i erased it.

so actually it would be better to solve your problem ( by posting ) a extra little timer project  
or called [MVCE](https://stackoverflow.com/help/minimal-reproducible-example)

even you need to invest some time, it will pay off for you and us.  
try this as a start:

```auto
// https://discourse.processing.org/t/only-countdown-when-mouse-at-a-certain-position/15635
// __________________________________________________ question about mouse over button ( ? but not pressed ? )
// __________________________________________________ and timer count down to 0 and shoot?

int b1x = 100, b1y =100, b1w =100, b1h =50;
long ts, tr=0, dt=10000; // _________________________ set 10 sec
boolean tenable = false,shoot = false;

void timer(boolean enable) {
  if ( enable ) { 
    tr = millis() - ts -dt ;
    if ( millis() - ts > dt ) {
      //println("timeout");
      shoot = true;
    }
  }
}

void button_b1() {
  timer(tenable);
  strokeWeight(2);
  if ( over(b1x, b1y, b1w, b1h) ) strokeWeight(5);
  fill(0, 0, 200);
  if ( shoot ) fill(200,0,0); 
  stroke(200, 0, 200);
  rect(b1x, b1y, b1w, b1h);

  fill(200);
  textSize(15);
  if ( over(b1x, b1y, b1w, b1h) ) {
    tenable = true;
    text( "t "+(tr/1000), b1x+5, b1y+b1h/2); // _____ show remaining time
  } else {
    tenable = false; 
    shoot = false;
    ts = millis();
    //println("reset");
  }
}

boolean over(int x, int y, int w, int h) {
  return (mouseX > x & mouseX < x + w & mouseY > y & mouseY < y + h);
}

void setup() {
  size(300, 300);
}

void draw() {
  background(200, 200, 0);
  button_b1();
}

```

also could help you about some of your coding habits.
