I am currently following along with Greenfoot Introduction to Programming using the little crab scenario, and one of my objectives is to end the game after my little crab dude has eaten all the worms. However, I made it so that new worms are added to the world whenever the crab touches the sides of the world. Therefore I cannot simply use an integer to tell the game to stop..? I have it set at 7 so if new worms are added to the world, the game still currently stops at 7. I have tried getWorld().numberofObjects but am unsure how to implement it. Thanks!
