You do not "go to a class". A class is some code that describes an object (it describes an instance of the class). You might have one Actor object go to some other Actor object within your World object. I am not trying to be difficult; just trying to give you pointers on how to get your problem across without confusion. The word "balloon" is ambiguous as well. I think, now, that you mean "bubble text" -- as if someone says something (like you see in a comic strip). Even though I replaced my previous post here, it is basically what I had written. You would draw the text image onto the "b

Use a class variable instead of an instance variable. Just add the 'static' modifier to the declaration line of the field. For example: <Code Omitted>The first line shows an instance field. Any object that is considered to be of the type represented by the class will get its own field with the name given. These fields

Ahhh thank you.

I will presume that Bloodstream is your subclass of World. You can use the following line to access it: <Code Omitted>The you can call the methods on 'bloodstream.

Please be more detailed. Give speed, direction relative to object, how far off object is missed, etc. -- especially code used.

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
