how？I thought for a long time but couldn't come up with the answer.

Add a constructor to the class and initialize the zombies through code there. You will probably need a static int counter to track which zombie is being created:

game over image not displaying

my Gameover class does not have any code as im just using it as an image. before the delay the game will just reach 8 points, that will start the delay, during the delay of 2 seconds I want my gameover image to be shown on the screen and once the delat of two seconds is over the game will restart

You will need some code in your GameOver world. At least something to set a new PongWorld object active. The delay should probably be in that class also: <Code Omitted>

Identify an actor

By misg, with 1 reply.
Replied to by danpost, almost 8 years ago:

how I can identify an actor? Let us assume there are 4 actors of the same in the world. How can I know and identify what is the 1,2,3 and the 4th of them? Is there a chance to have an activity if the actor is the actor number 2?

You could list them or give each a unique state; otherwise they would not be essentially identifiable. There may still be a way that could work; but it is not guaranteed to work in future versions of greenfoot. An undocumented behavior in the way greenfoot lists the actors that are placed into a world may be used to identify a specific actor.

How to end a game when a specific score is reached?

<< Code Omitted >> I just don't know how to make the game stop at 8 points, because ive used strings for the score im guessing I have to do it in an act method in the world class??

I am not sure what you mean by "ive used strings for the score". The getValue method of the Counter class returns an int value which is a score. Best places to check for game over is when you add to the scores (lines 47 and 53 of your PongWorld class).

Greenfoot export jar empty window

By JustDylan, with no replies.

I've been trying to export my greenfoot game for about 3 hours but I can't get it to work. github link this is the github page if the game, I am working in an external ide so that's why I am able to work in packages. it also fully functions in greenfoot. I think greenfoot doesn't know what the default world is when you execute the exported jar because it creates an empty window. anyways, does somebody here know why this is happening. I am using version 3.1 btw, in the newer versions there is no good way of using an external ide.

Abstract World, Health Bar

By fittirc04, with 2 replies.
Last reply by danpost, almost 8 years ago:

A couple things about your code: (1) instead of a field and a getter method in each Area World class, you can simply add them into the AbstractWorld class and inheritance apply them to all Area worlds. The getter method itself is not actually needed at all, provided the field has public access. Also, by making the field static and only creating a HealthBar object in your initial Area world, all areas can use the same health bar: <Code Omitted>

Can someone please help justifying classes and why they inheriting from actors. i would be very much appreciated. An example would more than enough so i can guide myself through thank you.

The World and Actor abstract classes are base classes for any and all worlds and actors. The greenfoot platform is built around these classes. You cannot create a world in greenfoot without a class that extends the World class and only Actor objects created from some extension of Actor are the only objects you can place into a

I'm not familiar with mouseClicked(). I have a shopping cart assignment which involves: The ShoppingCart (actor) will be a class with no image. The class will simulate purchasing the clicked on objects and required quantity. Must have Greenfoot.mouseClicked() and quantity = Integer.parseInt(Greenfoot.ask(Enter quantity:"); I have to be able to click the item image which is on the world and have it to let the player put in the quantity. Then have the number of items they inserted and the picture show on the world. << Code Omitted >>

The mouseClicked part look
