// Example 10-7: Drops one at a time

// An array of drops
Drop[] drops = new Drop[1000];

 // New variable to keep track of total number of drops we want to use!
int totalDrops = 0;

void setup() {
  size(400,400);
  smooth();
  background(0);
}

void draw() {
  background(255);

  // Initialize one drop
  drops[totalDrops] = new Drop();

  // Increment totalDrops
  totalDrops++ ;

  // If we hit the end of the array
  if (totalDrops >= drops.length) {
    totalDrops = 0; //Start over
  }

  // Move and display drops
  for (int i = 0; i < totalDrops; i++ ) { // New! We no longer move and display all drops, but rather only the “totalDrops” that are currently present in the game.
    drops[i].move();
    drops[i].display();
  }
