import greenfoot.*;  // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)
import java.awt.Color;
/**
 * Write a description of class Button here.
 * 
 * @author (your name) 
 * @version (a version number or a date)
 */
public class Button extends Actor
{
    public Button()
    {
        setImage(new GreenfootImage(" Try again ", 30, Color.BLACK, Color.RED));
    }

    public void act()
    {
        if(Greenfoot.mouseClicked(this))
        {
            CrabWorld gw = (CrabWorld) getWorld();
            gw.removeObject(this);
            gw.removeObject(ScoreBoard);
            gw.removeObject(Counter);
            gw.removeObject(Lobster);
            gw.prepare();
            

        }   
    }}

it says it cant find the variable for scoreboard counter and lobster and my goal is to remove these items because it just leaves them their and when you hit reset it just resets it with eveything their still but with the begining characters aswell anyways heres the code

Im back! You do not have to remove anything . Just call the prepare() method here. Back in the world class, in the prepare method, insert a new first line to the method

removeObjects(getObjects(null));

and make sure that a line is in the prepare method to add the crab also.

The button can be anywhere you want it to be. Just change the location to where you want it to be within the addObject statement that puts the button into the world. If you already have the words 'try again' on the scoreboard, you could place the button over the words.

If your reference is to the 'Try again' button, yeah. In the constructor, change the font size (30) to a larger number.

A simple score class would be something like

import greenfoot.*;
import java.awt.Color;

public class Scoreboard extends Actor
{
    score = 0;

    public Scoreboard()
    {
	updateImage();
    }

    private void updateImage()
    {
        setImage(new GreenfootImage("Score: " + score, 14, Color.black, new Color(0, 0, 0, 0)));
    }

    public void add(int change)
    {
	score += change;
	updateImage();
    }

    public int getScore()
    {
	return score;
    }
}

Sorry, ignore the above. I see you already have a counter for while the game is in progress. I now see that the scoreboard is for the end (more of a game over scoreboard). A scoreboard class for such would be something like

import greenfoot.*;
import java.awt.Color;

public class Scoreboard extends Actor
{
    public Scoreboard()
    {
        setImage(new GreenfootImage (" GAME \n OVER \n \n End Score: " + score + " ", 24, Color.black, Color.cyan));
    }
}

ok so what does that do? i dont understand i already have a end scoreboard i just want to put the new try again over the game over try again how can i make that appear then at the end?

1) In your getEaten() method in the crab class, you remove the crab. 2) In your act() method in the crabworld class, you check to see if a crab is in the world a) if so, do nothing special b) if not, add the scoreboard and add the button 3) When button is clicked, the prepare() method in the world is called and all the objects are removed and replaced.
