The error is probably not in the Body class, but rather in your World subclass where you try to create a Body object. You can add an import line for the Color class or change 'new Color(12, 12, 12)' to 'new java.awt.Color(12, 12, 12)'.

I would start by having two world constructors. The first one with no parameters would call the second one with an int parameter to indicate the number of squares along one side of the board. This second constructor should possibly create and set the background image and add the horse into the world. The act method could check for numeric keystrokes between 5 and 9 (perhaps) to recreate the world with a different size.

Remove all the 'else ...' from the animateDown method. You only need to make sure that if no down1...11 image is used (so coming from a different direction), you set one.

thanks very much danpost, it work out well, many many thanks danpost and super_hippo

Found it, thank you guys!

You might make use of my BgMusic class which is located in my BgMusic Actor Class Demo scenario. The class is designed to control the background music regardless of the active world. The use of the 'stopped' method is still required when the scenario changes from the running to the paused state (and the 'started' method when going the other way); but, no reference is needed to the BgMusic object because of the way the class was designed. All your World subclasses will need implementations of both the 'started' and 'stopped' methods if all

Open up the editor for the class (double click on class or right click and select 'Open editor'); then, add code to 'act' method.

Thanks, I hope it compiles Edit: IT WORKS! THANK YOU!

ok thanks for the help will try it out

Thanks I did it

Thank you for the replies Hippo & danpost! I will remember to return the value given by the method if I am creating an int, boolean, etc, in future then.. On another note, the method was removed and the randomised position was achieved through placing the 'getRandomNumber()' method inside the 'addObject()' method. As always, I appreciate the hard work you do supporting others danpost, thanks for the thought put into other ways I could achieve my goal too and thanks hippo for the straightforward and clear reply too!

Oh, ok. Thanks,

What have you tried? What do you think will be involved?

Alright. Btw, line 15 doesn't do anything since you are doing the same thing in the next line again. And if you change the 'coastalFrame' in line 16 to 'this', you can also remove line 10 ;)

Ok it works thanks
