There's a nice easy method that lets you change the location of a component...

whatever_label.setLocation(x_position, y_position);

To move the horse when they press the button, some sort of running position of where it is will be needed, and you'll be able to change the position according to where it was before.

Yha... but the catch is: this only work with Null Layout in this GUI was generated by Netbeans
If you want to do fancy stuff with a GUI do not use the GUI generator of an IDE

You have the choice between 2 worlds:
- or you do it yourself and do whatever you want with it
- or you use a GUI generator and stay with the look and feel and layout you created it with

I thought NetBeans did use a null layout. Hm...

(if NetBeans doesn't use a null layout) I could have sworn it works otherwise anyways, because I've used it to override NetBeans when it decides to put components other than places I specified...

-_-

Seems to use a GroupLayout
one of these layout introduced in JRE 1.6 for GUI generators but completly understandable for human beings

(Even if you and me can understand nested if up to 16 levels of depth

You can do it this way.
But you can't expect us to help you if you use an IDE to generate your GUI.

When you use a GUI generator form an IDE like NetBEans it prompts you for a lot of options, or provide you with a lot of Checkbox to check/uncheck... should it be transparent, should it be over the other components, should it be opaque, .... and so on

GUI generators generates hundreds of line of code that can be hardly understood by a human being

If you write your own GUI we will be happy to help
if you based your GUI on a GUI generator, unless you pay me a reasonnable hour fee I won't even have a look at it... and you will probably be wasting your money anyhow
May be the GUI generator offered you a few checkbox to check/uncheck and you didn't choose the right ones

If you have problems related to GUI generated by NetBeans go to the NetBeans forum
we fix human generated code not IDE generated code

And you are still welcome here

O I get it and completely understand

so I will throw some of my own code ut now what I want to do is
move the labels so could I do something like

Horse1.setLocation(Horse1.getX()+num,Horse1.getY());

with a for loop to keep doing this until it reaches a certain place on my applet

In a null layout it will work... you will also have to specify the size of the JLabel the GUI cannot just guess what it should be
