I think the easiest way to implement a Counter is by importing the Counter class with Edit → Import Class (Bearbeiten → Importortiere -sic- Klasse...). You add two instances of this class to the world (one for red, one for blue). Save a reference to the objects in your world so you can access them later. Then, when your red boxer scores: For the blue one, you use a 1 instead of the 0. The timer can also be another object of the Counter class. To show a message, you can either use the showText method or you create a new class which you can give an image showing a text (similar to what is done in the Counter class's update method).

My Value Display Tutorial scenario has all the information you need on this (in fact, you could have all the functionality in one class -- timer, both player scores and final scoreboard (could be called a Stats, for statistics, class). The only thing missing then, would be the players' access to to scoring, which is not too difficult. Get the class(es) created first, though EDIT: or import and use the Counter class as Hippo suggests.

Thanks, but the link doesnt work

Where do i need to copy the text?

Everything except the one-liner in the middle to the world, the line in the middle to the boxer when he should get a point. That's the correct link: http://www.greenfoot.org/scenarios/14834

sorry i still dont unterstand in which class.. haha

ok, can i copy u the code of my world subclass and u put the text in, so i dont do mistakes? thanks in front

i onl,y need it for school and dont wanna understand xD code comes soon

here is the code:

or u do it for me and after that u explain me how it works?

I also started with Greenfoot in school like four and a half years ago, but I continued programming with it and it became a hobby. Give it a chance, it's a lot of fun if you understand what you are doing. If a line starts with a for example "private", it can't be in a method. It is either a method itself (e. g. the theCounter method) or a variable (e. g. counter, timer, time...). The variables belong to the beginning of the class, just where in line 21, you already have a time variable. So instead of this line, insert these: In the prepare method, you add objects. (I really dislike the Save the World feature since it usually results in a mess like that for new programmers...) Anyways, I told you to add the three objects, so you can place this code in the prepare method: The getter-method for the counters is, as the name says, a method. So it could for example be in line 563: Then, you only need to add the act method in the same way. A new method must not be placed in another method, but anywhere in the class. I personally place the act method right after the constructor, so after line 33:

Thanks so much, I think i understand. I can try it tomorrow, bcos i dont have time anymore today
