You will need either the 'else' or the 'return;' statements (at least the first one). I do not see how line 13 would have caused the error you were getting. The act method will not execute for an actor not in a world and there is nothing that will remove it before that line.

thank you very much that works perfect.

You could put something like this in your World subclass act method: <Code Omitted>

ist schneller meistens, ich schau auch nur abundzu auf greenfoot vorbei, bin aber den ganzen am pc also antworte ich auch innerhalb von ein paar sekunden :P

You are creating an alternate world instance with the first line. You want the score from the real world. Use this for the first line <Code Omitted>Also, the code given must be executed while the actor is in the world. So, move it from the constructor -- override the 'addedToWorld(World)' method of the Actor class and add the code in it: <Code Omitted>

Thank you very much! It worked great! I have another question if you wouldn't mind helping me: https://www.greenfoot.org/topics/60449/0#post_124333

Thank you very much! :)

Don't change it every act cycle. So for example changing the image every second act cycle (half speed). <Code Omitted>

In your Lawn class, the constructor would begin with: <Code Omitted>and the constructor calls takes a minimum of 3 parameters:. Its either 'super(int, int, int)' or 'super(int, int, int, boolean);'. Refer to the World class API documentation on its constructors.

Oops. Right

Line 10 in the Person class does not make any sense (remove it). Also, lines 12 through 16 should be in the act method -- not in the constructor.

why do you instantly setImage 12 times? you will only see the last one Greenfoot should show you where the error is, probably used wrong filepath

You have a type for the parameter of the method -- but no name for the parameter: <Code Omitted>Also, you can remove line 2 (imported with line 1).

<Code Omitted>

Thank you very much! It's working now, since I've changed the Menu class!!!
