Use: ((MyWorld)getWorld()). followed by variable name.

I have a variable nrOfSteps in the subclass man of the class Actor, which must go to the subclass Level 1 of class world

Okay. I had the variable being passed the wrong way (misled by title). Keep a reference to the man actor in your Level1 class so you can use man.nrOfSteps.

How do I do that? Can you give an example, because I just started working with greenfoot for a school project?

I tried this: <class>.<variable> = <value> but it didn't work. Its says: non-static variable connot be referenced from a static context

//outside method in world (Level1)
Man man = new Man();

// inside method in actor
<class> <variable name> = ((Level1)getWorld()).man.<variable>;
//example
int steps = ((Level1)getWorld()).man.nrOfSteps;
(always begin class names with uppercase letters and variable names with lowercase letters -- as per convention). Make sure that the Man object created here is the one that is placed into the world -- not another created Man object.
