What does your code look like so far?

You could try creating and writing to a file, and then try to open and read the file and if it fails you are probably on the site.

There are also a pair of short videos in the 'Documentation' area of Greenfoot that explain 'Running, Jumping & Falling (Part ? of 2)'.

Check out the discussion at www.greenfoot.org/topics/220. The basic code for the angle (and distance) is given there.

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
