Greenfoot

Hi, so I am working on a game for school and I need to make a scoreboard. When I first made it, it wasn't actually counting whenever I picked something up like it was meant to. I asked my friends for help but for some reason their code didn't work for me. What can I do? I need the answer ASAP since I am going on holiday tomorrow and can't work on it there. Lines 45 - 60 below are related to my scoreboard.

import greenfoot.*;

/**
 * This class defines a crab. Crabs live on the beach.
 */
public class Crab extends Actor
{
    private String[] down;
    private String[] up;
    public String[] left;
    public String[] right;
    public int frameCounterLeft;
    public int frameCounterRight;
    public int frameCounterDown;
    public int frameCounterUp;
    public int wormsEaten;
    public Crab()
    {
        down = new String[4];
        for(int n = 0; n<down.length;n++)
        {
            down[n]="SansDown"+n+".gif";
        }
        up = new String[4];
        for(int n = 0; n<up.length;n++)
        {
            up[n]="SansUp"+n+".gif";
        }
        left = new String[4];
        for(int n = 0; n<left.length;n++)
        {
            left[n]="SansLeft"+n+".gif";
        }
        right = new String[4];
        for(int n = 0; n<right.length;n++)
        {
            right[n]="SansRight"+n+".gif";
        }
        frameCounterLeft=0;
        frameCounterRight=0;
        frameCounterDown=0;
        frameCounterUp=0;
    }

    public void act()
    {
        wormsEaten = 0;
        movement ();
        getWorld().showText("Score: "+wormsEaten, 100, 50);
        if ( isTouching(Worm.class) )
        {
            wormsEaten = wormsEaten +1;
            removeTouching(Worm.class);
            Greenfoot.playSound("slurp.wav");
        }

        if (wormsEaten == 6)
        {
            WinWorld win = new WinWorld();
            Greenfoot.setWorld(win);
        }
    }

    public void movement ()
    {
        if (Greenfoot .isKeyDown("a"))
        {
            move(-5);
            if (frameCounterLeft<4)
            {
                setImage (left[frameCounterLeft]);
                frameCounterLeft++;
            }
            else
            {
                frameCounterLeft=0;
            }
        }
        if (Greenfoot .isKeyDown("d"))
        {
            move(5);
            if (frameCounterRight<4)
            {
                setImage (right[frameCounterRight]);
                frameCounterRight++;
            }
            else
            {
                frameCounterRight=0;
            }
        }
        if (Greenfoot .isKeyDown("s"))
        {
            setLocation(getX(),getY()+5);
            if (frameCounterDown<4)
            {
                setImage (down[frameCounterDown]);
                frameCounterDown++;
            }
            else
            {
                frameCounterDown=0;
            }
        }
        if (Greenfoot .isKeyDown("w"))
        {
            setLocation(getX(),getY()-5);
            if (frameCounterUp<4)
            {
                setImage (up[frameCounterUp]);
                frameCounterUp++;
            }
            else
            {
                frameCounterUp=0;
            }
        }
    }
}

That's my code ^^^^^

Remove line 47 or you set the variable to 0 every act-cycle. It is also enough to use the "showText"-method after the variable changes (and once at the start). No need to replace it every time when nothing changes.

Thanks, but is there any way that I can have the exact same appearance for my scoreboard, it's just the scoring element that's broken.

Not exactly sure what you mean with "exact same appearance". One little problem I see is that you use showText before you check for worms you eat. So the counter is always one act cycle too late.

One problem I see is that line 47 needs to be removed.

Sorry, the "exact same appearance" thing was weird. It works now, thanks!
