Trying to make PacMan and the Ghosts bounce around.

Silvestri78

I'm having an issue where Processing is telling me that function move does not exist. I believe that this is linked to the other issue that I'm getting which is variable x and variable y do not exist. For the life of me, i am unable to see the issue. If any of you are able to show me what my issue is or even point me in the right direction I would be eternally grateful. Thank you for your time and advice. I apologize in advance there is a lot of code but I wasn't sure if the issue could be solved if I only posted bits and pieces.

Clyde.move();

The way you are calling this it is expecting move() to be a method within the Clyde instance of the Ghost class, which is where it should be.

But your move() is at the same level as setup and draw, not part of the class...

koogs

void setup() {
  Dog fido = new Dog();
  Cat fluffy = new Cat();

  println("Cat noise: " + fluffy.noise());
  println("Dog noise: " + fido.noise());
}

// something that makes a noise implements all the classes defined here    
interface makesNoise {
  String noise();
}

class Cat implements makesNoise {
  String noise() {
    return "meow";
  }
}

class Dog implements makesNoise {
  String noise() {
    return "woof";
  }
}

note the classes (Dog, Cat) traditionally start with a Capital but instances (fido, fluffy) don't.

(look closely and you'll see that your ghost and your pacman are the same...(apart from how they appear))
