I want my counter to go up to 15 (when my main actor collects 15 targets) how do I achieve this?

You will need to add the following method to your Counter class:

public int getPoints()
{
    return points;
}

Then, after calling 'addPoints', you can use and 'if' block with the condition '((Counter)getWorld().getObjects(Counter.class).get(0)).getPoints() == 15'. To help simplify things:

Counter counter = ((Counter)getWorld().getObjects(Counter.class).get(0);
counter.addPoints();
if (counter.getPoints() == 15)
{
    /** whatever you want do do */
}

    }

    public void addPoint()
    {
        points++;
        updateImage();
    }

    public Counter()
    {
        updateImage();
    }

    public int getPoints()
    {
        return points;
    }
    
}

No. The six-line snippet is what you use in the class of the character that collects targets. The first line gets a reference to the Counter object so that the following lines can execute the 'getPoints' and'addPoints' methods on it.

lines 3-5 of what you posted in the Counter class, do not belong in that class. You need to put those lines at whatever point it is that you want to increase the count - that is, whenever your main actor collects a target. This will probably be in the main actor class.
