@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!

@Duta, Do not sweat it! We all, or most of us, at least, are guilty of it from time to time. We are so eager to help that we miss the clues that matter. Again, it would have helped had the information been provided. We keep stressing the need for clarity, so the help can be more tailored to their needs.

If your actor is only to move 'up' and 'down', then you do not need to use all this code with Math functions and all. Even if you have it as a sub-class of Mover, you do not have to utilize this code. I threw this code together, controlling the direction with the arrow keys

Or nesting it within the mouse event checks like mouseMoved or mouseDragged. <Code Omitted>

okay thanks

thank you

sorted it now but thanks
