i need help making the game end if my counter reaches 13, here is the counter code if you need it:
import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)
/**
* Write a description of class Counter here.
*
* @author (your name)
* @version (a version number or a date)
*/
public class Counter extends Actor
{
int score = 0;
/**
* Act - do whatever the Counter wants to do. This method is called whenever
* the 'Act' or 'Run' button gets pressed in the environment.
*/
public void act()
{
setImage(new GreenfootImage("Score: " + score, 24, Color.BLACK, new Color(0, 0, 0, 0)));
}
public void addScore()
{
score++;
}
}
