Hi, First of all sorry for my bad English, I'm from Germany. Now to my questions: How can I make a Counter/Scoreboard in my game, which counts the coins collected of my 2 player classes. One for the player/class and another one for the other player/class. If u need the code of the game, I can copy it right here. Also, I want to make a Timer in my game, which counts down from 30 Seconds to 0 and which is visible in the game. After it counted down to 0 there should be a message in the Game, not the one with system.outprint. In the message should be written: "Red boxer, blue boxer (depends on who collected more coins during the 30 seconds) won, because he collected more coins". How would be a code for this and how can I make, that there is standing, that the red boxer won if he collected more coins or that the blue boxer won if he collected more coins. I hope u know what I mean xD thanks in front (?) FeVo

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. 
private Counter counter[] = {new Counter("Roter Boxer: "), new Counter("Blauer Boxer: ")};

//when adding the objects
addObject(counter[0], 70, 30);
addObject(counter[1], 120, 30);


//method to return the counter
public Counter getCounter(int i) {return counter[i];}
Then, when your red boxer scores: 
((MyWorld) getWorld()).getCounter(0).add(1); //change MyWorld to the name of the world
For the blue one, you use a 1 instead of the 0. The timer can also be another object of the Counter class. 
private Counter timer = new Counter("Zeit: ");
private int time = 30*55; //about 30 seconds

//adding it
addObject(timer, 170, 30);

//decrease it every 55th act cycle
public void act()
{
    if (--time % 55 == 0)
    {
        timer.add(-1);
        if (time==0)
        {
            if (counter[0].getValue() > counter[1].getValue()) //red won
            else if (counter[0].getValue() < counter[1].getValue()) //blue won
            else //draw -- Unentschieden
        }
    }
}
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.

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

You should have a world subclass. Maybe it is called MyWorld (default) or you renamed it to something else (e. g. Welt).

You could, but you could also tell us what you don't understand and maybe we can guide you so you figure it out yourself.

You could, but you could also tell us what you don't understand and maybe we can guide you so you figure it out yourself.
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: 
private Counter counter[] = {new Counter("Roter Boxer: "), new Counter("Blauer Boxer: ")};
private Counter timer = new Counter("Zeit: ");
private int time = 30*55; //about 30 seconds
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 coordinates should be altered so they are added to the correct position
addObject(counter[0], 70, 30);
addObject(counter[1], 120, 30);
addObject(timer, 170, 30);
The getter-method for the counters is, as the name says, a method. So it could for example be in line 563: 
public Counter getCounter(int i) {return counter[i];}
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: 
public void act()
{
    if (--time % 55 == 0)
    {
        timer.add(-1);
        if (time==0)
        {
            if (counter[0].getValue() > counter[1].getValue()) //red won
            else if (counter[0].getValue() < counter[1].getValue()) //blue won
            else //draw -- Unentschieden
        }
    }
}

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