thank you very much. I now have an own idea:

Thanks! It works now.

Show the act method of the class.

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:

For those interested, the summarized jumping tutorial is located here.

In class Main you can put the following in the act method. <Code Omitted>

oh i did one thing wrong let me correct it...i reaaly- ...Nothing.

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. By including an act method
