Hi danpost, I'm sorry i accidentally pressed enter without writing my question. My question was supposed to be What does this piece of code do, which you have said. But i'm still not sure what this bit mean: public void lookForFly() { if ( canSee(Fly.class) ) { eat(Fly.class); FlysEaten++; Thank you so much.

it is pretty self explanatory... public void lookForFly() { declares a method, and in the method... if (canSee(Fly.class)) { tests if the method canSee() returns true when you pass in Class Fly.class. if it does return true... eat(Fly.class) it calls the method eat(), passing in Fly.class, then... increments the FlysEaten variable by 1. In this example, you would need the methods canSee(Class) and eat(Class), neither of which are included in Greenfoot.
