You want the ball to turn, and not rotate? You are using the "setLocation(int newX, int newY)" method to move your ball. setLocation() moves your ball in an absolute way. It doesn't care which direction your ball is facing in, it will still move it in the same way. I think that what you want is the "move()" method, which is in the "Animal" class I think. Just make Ball extend Animal instead of Actor, and use "move()" instead of "setLocation()". I hope this helps!

Thanks ! img.setTransparency is a really good code!

Thanks Morran ...I think my keyboard must be very different! However I found that the key to the left of the "Z" works (eg Shift +\) it shows as a dotted line on the keyboard but produces "|" (apparently its called a "pipe"! Rich

What is the name of your World class? Is it "MyWorld"? "CrabWorld"? Your method in the World class is probably actually in the World's subclass. Try this(assuming that MyWorld is the name of your World): <Code Omitted>

YES! That's what I was after. Thanks again danpost, you forum ninja :D

Yes I just need the image. Thank you both very much!!!

Greenfoot is actually just meant to be a stepping stone. However, you can do a lot more with it than I think the developers meant. Your games can look quite good, just look at Nightmare: Emergence, Chicken, or my favorite, RockSmash. It just depends on how much work you want to put into your game. Most of the people on here are just using Greenfoot as a learning tool. They don't intend to sell or distribute their games.

@Morran Matrix :D. <<Uneducated mind

Thank you danpost for the detailed reply. I really appreciate it! @builderboy2005--thanks for pointing that out. Sophie

The Greenfoot and Java APIs contain methods that can be used in your code. The code itself is the basic Java language; and how you put your java language statements together is the artform that creates the code. The methods found in the Greenfoot and Java APIs are there because those methods (or groups of methods) are commonly used and you do not have to re-write them to apply them in your code. Yes, the Java API documentation is quite extensive and can be very confusing, but there are also tutorials (trails) you can follow to acquire a better insight on how much of it can be used. Check o

Thanks, worked great!

@danpost & davmac: Your suggestion to addObject from the Piano world did work. :) Thanks!

@Game/maniac, actually 'void' means that the method will not return anything. If it is 'boolean', the method is declared to return a true/false value. If it is 'String', the method is supposed to return a String value (or null). Basically, if the method is declared to return 'void', the method just does stuff and exits. But if it is not void, the method may or may not do some stuff and then, return an object of whatever type the method is declared to return.

The key is to ask for help when you need it. When you want to do something, have a think about how to do it and write what code you can - but if you get stuck, just post it on the gallery and ask for help. You can also look at other people's code, and try to figure out how it works. You can learn a lot that way!
