Hey do not judge on me please. I had no idea what in hell Pastebin was. like I said I'm beginner. If there is still problem with Pastebin or something, please post me specifically or give more details.
It is great that you've learned to use the code-tags. But as many have tried in various ways to tell you, big chunks of code are hard to read and difficult for anyone but the original coder to understand, especially without comments.
When you're posting large chunks of code while writing a message, in the editor you'll find a link just below the big white text-field, where it says: "Got extraordinary long code dumps? Use our pastebin to keep your thread readable. (link opens in new tab)". If you click the link, a new pane/window will open, and you can paste your code in there. Then you click "Post Code", and you get a link which you can use in your message.
Large chunks of code tend to make people think "Gah, I'm not reading through that!", but if you post a nice, detailed description of your problem, and supply a Pastebin-link, then people interested in helping with the proposed problem, can sit back and look at just the code, and in a separate window, making it much easier to write a reply, without scrolling back and forth.
Hope this helps. As to your problem, it seems you've got plenty of good advice. Just reset the fields associated with your game, and restructure it to use an init-method. It'll make your life much easier.
