Guys, I thank you from the bottom of my heart. Really help me a lot

Thanks for all the help, I got it to work correctly now.Thank you

cool, thanks

Awesome ^^ Glad to help!

I simplified your 'healthcheck()' method as follows: <Code Omitted>Three simple statements; no 'if's; includes 25 as a possible return for gethealth(); allows a health range of (-24, 1025) .

We know what causes the bug, so for now it is a fixable problem :) No rush!

giordanno92, the method described in this topic can kind of help you accomplish what you want. We've used Netbeans to create a utility library for managing high scores. (Okay, really it was to learn Java I/O, but it has a use.) It was easier to do in Netbeans and it helped my students to expand their understanding. Then we will link back to these classes, as described in this topic, and use them in Greenfoot

Thanks i try it

import javax.swing.JOptionPane and javax.swing.JInternalFrame. and put this code when you want to show the message: <Code Omitted>replace "Message content" with the message, and "Message title" with the title of the message.

Just add an instance boolean variable to the class -- call it something like 'fillObject'. <Code Omitted>Then, anytime the 'f' is pressed, change the value of 'fillObject' <Code Omitted>lastKeyPressed should be set up as a String variable and loaded with a non-null keystroke acquired through Greenfoot.getKey(). Finally, when drawing your objects: <Code Omitted>would fill the object if fillObject was true and not fill the object when false ('objectName' would be whate

First off, what import statements are in your Canvas class? Secondly, you do not need to say 'java.lang.String' as 'String' is sufficient. Thirdly, why are you using 'isKeyDown', when you have already stored the keystroke in 'k'? Just say, 'if ("1".equals(k)) { ... }', etc. But before that, make sure that k is NOT 'null' !!! <Code Omitted>etc. Something else, 'background.fill(white);' is not a valid statement. You need to use 'background.setColor(C

Ahh, I've never touched on logarithms. Heard lots about them, but never actually know what they are or what they do :D.

Awesome! Good luck with it :D!
