Health Bar

question: if i have one actor as a subclass to its counterpart, would they be storing their health value in the same location?

No, unless you declare the field as "static", but it's best not to do that if you can avoid it (it's bad from a design point of view). However, you can solve the problem by setting the health level of one actor at the same time as you create it from the other one.

thanks! only issue with that is that jumpCounter remains at 20 even after the key is released, so a second keyDown check such as the following is needed to reset the count so that the actor could jump later if(!(Greenfoot.isKeyDown("w"))) jumpCount=0;

Um, I'm not too sure about what you're trying to do, but wouldn't it be better to create an abstract class "Piece" with declared GreenfootImage blackImage and whiteImage, and then in the constructor have a blackImage and a whiteImage parameter, this way with superclass constructor chaining you can ensure every Piece will have pictures? Then, whenever the piece is moved, check the color of the square it is moving it to (again, with a superclass method somewhat like this...

When I say array-like, I mean that it starts with 0.

Ok - the proper name for that is "0-based indexing" (as Java arrays use), though in this case the x/y values aren't really meant to be so much indexes as they are distances from the top left cell. Regardless we could say that the co-ordinates are "0-based".

Um, you mean bounded, right?

Yes, I meant bounded, sorry.

Yes, a very big difference. By saying <Code Omitted> you are saying "Get the world! do nothing with it. And then try to removeObjects" But only the world is able to remove objects, so you need to do this: <Code Omitted> which says "Get the world, and then *use* the world to remove this object" which is what you want
