First thing is that it is not the class that has coordinates -- it is the objects of the class (that are subclasses of Actor) that have coordinates. That being said, you need to acquire a reference to the Om object in your world from within the Rac class. If there is always an Om object in the world, you can use: <Code Omitted>to acquire that reference (in 'om'). However, if it may be possible that there is no Om object in the world, you will need to preface that with the following:

if you could tell me how to move the selector to a different location that would be great.
Do you want the selector at a different location initially or do you want to be able to drag it with the mouse while the program is running? If you could explain why you would want to do this, it would help.

Using method from subclass in superclass

Oh wow, simply fix haha.. Now that it's fixed, how would I actually go about using a method from a subclass? Might be useful later.
You simply cannot. At least, not without first declaring the method in the superclass or one of its superclasses. The 'act' method of the Actor class is a prime example of this. In the Actor class, you have something like this: <Code Omitted>an act method without any code to implement -- which is called during an act step (or when manually executed) by code within the greenfoot framework.

Overwrite method from the act-method?

Yeah, that's right, the superclass doesn't make sense (as many parts of my project) but still, if the text is removed, the text will appear again through the act - method as the condition didn't change. But I may just add another variable so the if - cause is wrong after performing once.
Best might be an int field that is set to the round number when showing the text (using the condition that it is not yet the current round number).

You could probably scroll one background image, as opposed to using the background gif images, to free up some memory.
