How do I design, in Dog World, a player-controllable Dog object? I know how to create a new Dog object, but am confused as to how to relate it back to a class called MyDog.

So, the class is MyDog and you are creating a object called dog, right?
What do you mean relate it back? Do you mean a superclass or a subclass of MyDog?
//something like this? In the World: MyDog dog = new MyDog(); super(whatever dimensions you've stated); addObject(dog, blasted coordinates);
That code wouldn't compile: call to super MUST be the first statement. Instead, use this:
This would only work btw when this code is in a subclass of World.
super(someints); MyDog dog = new MyDog(); addObject(dog, x,y);
Thank you for responding. I had already figured it out and SPower, that is what I used to make it work.
Instead of using:
you could use:
This makes it alot easier if you are adding alot of objects!
MyDog dog = new MyDog(); addObject(dog, x, y)
addObject(new MyDog(), x, y);
@steved, If the dog in question is to be player-controlled, a reference to that dog would be helpful. In fact, the declaration of should probably be in with the world instance fields (that is, declared outside any methods; but still within the class code) with in the constructor.
As an alternative could be declared and in the constructorbut, I prefer the former way for objects that are to be in the world at start-up.
MyDog dog = new MyDog();
addObject(dog, x, y);
MyDog dog = null;
dog = new MyDog(); addObject(dog, x, y);
