Blinking random objects in arrays

[myhatzulu]

finally managed to work it out with great help from someone, problem was in void blinkCheck(){}

  void display() {
    if (count % 60 < 30) {
      blinkM = true;
    } else {
      blinkM = false;
    }

    if (blinkM == true) {
      diameter = 30;
    } else {
      diameter = 0;
    }
    noStroke();
    fill(0);
    ellipse(x, y, diameter, diameter);
  }
}

void count() {
  count++;
}
