My aim is, to have more than one level in a game. I want to use the same actor "Fels" with different images in the different worlds. Here is the beginning of my procject: World -> BeuteltierWelt -> IceWorld Actor -> Fels Within the constructor of the class "Fels" i wrote: 
public void Fels()

World hier = this.world();

if ( hier == BeuteltierWelt)
 { setImage (sandrock.png);}
 else
   if (hier == IceWorld)
    { setImage(icerock.png);}
    else
     { setImage( water.png);}
The identification of the calling world doesn´t work. I always see "water". How to write the correct code greetings from tollpatch

First, the code you gave is not a constructor (constructors do not have return types). Second, 'world' is not a method (maybe you meant 'getWorld'). Finally, if you did mean 'getWorld', it would not work in a constructor because the object being created is not yet in a world. There is a method you can put similar code in that would run once immediately after the object was placed in a world -- the 'addedToWorld(World)' method, which is called automatically (you do not have to call the method for it to execute). Now, before going on, I cannot believe that the code you gave even compiled for many reasons. I want you to copy/paste (literally) that method and post it exactly as it is in your project.

Have a look at this scenario. It should help you out if you just look at how to change the world from the Pengu class. http://www.greenfoot.org/scenarios/3061

Thanks danpost and Phytrix for quick replies, danpost, its right that some mistakes are in the code which more represent my ideas. Phytrix, your link was very helpful!! I learned to give a value to the constructor methode. My theoretical wiches are fullfilled: One class is used in all worlds, but with different images. In each level each object can apear with its different image. Thanks for support
