Game Help.working on it for days,.

NVM,.thanks for evry1

[Fubarable]

You're much better going through the Swing tutorials and learn to write something like this from scratch. That way you'll learn much more and will understand all parts of your program. Much luck.

[xSkittlesx]

ok,.ill try,.. cheers

[Fubarable]

I wish you much success! Oh, and welcome to the Java-forums!

[xSkittlesx]

thank you,.. guess ill be staying hir in dis forums for a while since i jst started doing computer science as a major. can you atleast tell me what is missing/wrong with the code i posted??

Perhaps others might, but many here try to help folks with their code only and not with code they've borrowed. My experience has shown that it's just not that rewarding for me for many reasons.

[Norm]

the game just doesnt initiate

What does that mean?
Does the program compile ok?
How do you execute it after a successful compile? Do you have an html file that goes with it? I don't see any references to an applet class.

[xSkittlesx]

the code was originnaly an applet. but i need a JPanel so i tried to remodel d code. i execute it, but it's jst showing me a black screen with the score,time and level in d bottom of the panel, and d cross hair pointer. no balls moving around.

[Webuser]

put your code into code tags please. It is unclear...

[xSkittlesx]

i updated d code, but i get a nullPointerException!! hir is d code!!

sorry,im new to this forums so i dont know how to do this code tags!

[Norm]

i dont know how to do this code tags

Look at the icons above the Message box. Run your cursor over them. One will say "Wrap code tags around ...". Its the #
Edit your post, select the code and press that icon.

[Fubarable]

Or you can manually place the tags into your code by placing the tag [cod&#101;] above your pasted code and the tag [/cod&#101;] below your pasted code like so:

[code]
  // your code goes here
  // notice how the top and bottom tags are different
[/code]

Luck!
