my world class

Line 18 alone removes all objects from the world.

Alright. Thanks a lot :)

The mouseDragged method requires an object, not a class. So for a start, replace 'Pet.class' with 'this'.

You can have a variable used as a timer in your world. <Code Omitted>

Do you change the image in your act method? Or in other words, if you don't start the scenario and add a Puppy with right click on the class, is the image huge or 20x20? Are you sure it is compiled? Sometimes, when the auto-compile doesn't work anymore, you have to restart Greenfoot.

<Code Omitted> True, but it is quite complicated to remove the object and re-add it instead of simply change its location.

I do not see where 'c' is declared as a variable. Also, I do not see where 'd' is used anywhere (although it might be used elsewhere).

Well, you need to create a subclass of World for the game over screen; also, you will need to add the final score text to that world (either onto the background or by use of an actor). Easiest way to accomplish that is to break line 3 above into the following: <Code Omitted>so you can add the a

Thanks for the reply, but i think in order for that to work, i need to be able to turn RoundRectangle2d.Float into arrays of x and y coördinates. The RoundRectangle2D.Float class doesn't have this. I have however found a way to fill it in though. All i needed to do was add ovals to the 4 corners and add two squares in a cross pattern.

Apparently it doesn't find an image with the name 'title.png' (line 1 in the terminal window). Make sure an image with exactly that name exists in the image folder of your project.

Create an act method in your world subclass. Increase or decrease a variable (used as a timer) in the act method and whenever it hits a defined number, spawn a new Enemy and reset the timer.

Show how you wrote it. Verify that the file name matches correctly with what you wrote (case-sensitive) and is located in the proper directory folder.

See here.

It runs now. Thanks!
