I am doing the turtle thing and im trying to add a snake to eat the turtle. but when i set it to eat the turtle when it can it says cannot find symbol. My code is import greenfoot.*; public class Snake extends Actor { public void act() {move(3); if(Greenfoot.getRandomNumber(100)<10) { turn((Greenfoot.getRandomNumber(40)-20)); } if(canSee(Turtle.class)) { eat(Turtle.class); } if(atWorldEdge()) { turn(13); } } } any help would be appreciated.

Probably you havend declared one (or more) of the methods you are using. Does it say which symbol exactly it isn't able to find? Or in which line the error occours?

More specifically, the only things it would have a problem finding are (1) 'canSee', (2) 'eat', and (3) 'atWorldEdge', which are all methods in the Animal class. Since your Snake class extends Actor and not Animal the compiler cannot find those methods. As an alternative to sub-classing the Animal class, you can copy those methods from the Animal class into the Snake class.
