I need to figure out how to stop the entire game when the Worms, Crabs, or Lobsters number, or population, equals zero. This is what I have now, but it's not working.
public CrabWorld()
{
super(560, 560, 1);
populateWorld();
act();
}
/**
* Create the objects for the start of the game.
*/
public void populateWorld()
{
int i = 0;
for (i=0; i<5; i++)
addObject (new Crab(), Greenfoot.getRandomNumber (561), Greenfoot.getRandomNumber (561));
// Hartley - this code randomly adds 5 crabs each time the world is reset. This code satifies R1
for (i=0; i<2; i++)
addObject (new Lobster(), Greenfoot.getRandomNumber (561), Greenfoot.getRandomNumber (561));
// Hartley - this code randomly adds 2 lobster each time the world is reset. This code satifies R2
for (i=0; i<50; i++)
addObject (new Worm(), Greenfoot.getRandomNumber (561), Greenfoot.getRandomNumber (561));
// Hartley - this code randomly adds 50 worms each time the world is reset. This code satifies R3
}
/**
* Stop the game once all the Worms, or Crabs, or Lobsters’ numbers (population) reaches zero.
*/
public void act()
{
if (getObjects(Worm.class) == null || getObjects(Crab.class) == null || getObjects(Lobster.class) == null)
Greenfoot.stop();
}
}
