Right now i load the program, click level one and then i can select the radiobutton for the Redblock and when i try to then click the move right Jbutton which in the action listener i programmed it to move, and it dosen't ive tryed for like 3 days and im still stuck. Thanks i will include my loading pictures class that loads and draws the imageicons, and my labelframe with has the actionlisteners and everything else. the first class i posted is labelframe then the loading pictures class.

You will want to look up the tutorial on Swing Timer and use one for your animation. — Hovercraft Full Of Eels, Jan 13 '13 at 02:00
I just did im looking at it, and will it still work with my Jbutton so it ony moves when the button is clicked? — Nick B., Jan 13 '13 at 02:10
Why include the overhead of an ImageIcon just to load an image? Use ImageIO instead, it's more direct. — user1354999, Jan 13 '13 at 05:47

This example moves a line using buttons or the keyboard. You can call drawImage() in paintComponent() instead of drawLine(). The essential step is to call repaint() after each change in position.

In addition to trashgods example, you could also check out

While a little off topic, animation is complex topic. There are number of really good open source Swing based animation libraries you could use to make your life easier...

Both are excellent and are based around a similar theory, but do different things. You will have to determine if they are suitable for you needs.

So long as you have a basic understanding of the paint process & concurrency in Swing, you should be right – MadProgrammer Jan 13 '13 at 02:40

@NickB: Good. That's how you move on out of intermediate beginner range. – Hovercraft Full Of Eels Jan 13 '13 at 02:40
I have got it to work, i ended not using the suggestions but i will use them to learn from, i need to make my radiobutton an action listener and then had to put the jbutton inside that. Thanks for all the help! – Nick B. Jan 13 '13 at 03:34
