but does not scroll
What do you mean with that and where are you trying to achieve it within your codes?

all i'm trying to do is just muddy the code and understand, for example, i try to score when an emoticon 1 touches the emoticon 2 with arrows, i'm not going out a game quite done , I miss it, three lines of code, I think, but I can not display 1 when the emoticon 1 touches the emoticon 2, it's all stupid as a trick, that's it

MyWorld: Change "GetCounter" in line 20 to "getCounter" Remove lines 36-41. Use the following in Emoti1:
?
1
2
3
4
if (isTouching(Emoti2.class))
{
    ((MyWorld) getWorld()).getCounter().addScore();
}

if I use your line of code, my emoti1 will not be able to touch the emoti2 anymore and will not display the score

What @Hippo suggested was accurate. The code, however, did not provide the line to "eat" the Emoti2 object:
?
1
2
3
4
5
if (isTouching(Emoti2.class))
{
    ((MyWorld)getWorld()).getCounter().addScore();
    removeTouching(Emoti2.class);
}
Make sure you do everything else:

It might help if you change the Counter class to the following:
?
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
public class Counter extends Actor
{
    int score = 0;
     
    public Counter()
    {
        updateImage(); // initial image
    }
     
    private void updateImage()
    {
        setImage(new GreenfootImage("Score :" + score, 20, Color.WHITE, Color.BLACK));
    }
     
    public void addScore()
    {
        score++;
        updateImage(); // new score image
    }
}
This creates a new image for the Counter object only when needed -- not every act step.

I realized that I put twice counter counter = new counter, normaly it was not displayed when you do delete from the right click, the line of code in world does not erase automatically and moreover i did not change the act
