I want to include (upload) code along with my coding questionHello. Here is some code I am having problems with. I have read and read and tried out different methods before asking this question but I just can't find what I am doing wrong. I know it must be something basic though., but the answer eludes me. Currently, if Pengu eats Broccoli or Nuts he gets 5 points for each one eaten - works great. I want to implement two separate counters, one for Broccoli and one for Nuts.
Below is code for scenario which works fine and also my attempt to get scenario working with 2 counters. Thank you.
Below is code that does not work. Can't get second counter working.
import greenfoot.*;
/**
* Working Scenario. Pengu has nuts and broccoli to eat. Can move left or right.
*/
public class Pengu extends Actor
{
private int points =0;
private Counter counter;
/**
* Counter to count number of nuts and broccoli eaten. 5 points for each eaten.
*
*/public Pengu (Counter pointCounter)
{
counter = pointCounter;
}
public void act()
{
checkKeys();
tryToEatNut();
tryToEatBroccoli();
}
private void checkKeys()
{
if (Greenfoot.isKeyDown("left") )
{
setImage("pengu-left.png");
move(-4);
}
if (Greenfoot.isKeyDown("right") )
{
setImage("pengu-right.png");
move(4);
}
}
public void tryToEatNut()
{
if (canSee(Nut.class))
{
eat(Nut.class);
points++;
counter.add(5);
}
}
public void tryToEatBroccoli()
{
if (canSee(Broccoli.class))
{
eat(Broccoli.class);
points++;
counter.add(5);
}
}
/**
* Return true if we can see an object of class 'clss' right where we are.
* False if there is no such object here.
*/
public boolean canSee(Class clss)
{
Actor actor = getOneObjectAtOffset(0, 0, clss);
return actor != null;
}
/**

* is such an object where we currently are. Otherwise this method does
* nothing.
*/
public void eat(Class clss)
{
Actor actor = getOneObjectAtOffset(0, 0, clss);
if(actor != null) {
getWorld().removeObject(actor);
}
}
}import greenfoot.*;

}You have two pengu constructors both with the same name they are both with a variable in it, the name and the parameters are the same even though the name of the Counter variable is different. To do what you are attempting (I don't know about the rest of the code) try this: You should have a syntax error on the second pengu constructor that you didn't mention, it all has to be in the same constructor.
public pengu(Counter)
/**
* Counter to count number of nuts and broccoli eaten. 5 points for each eaten.
*
*/
public Pengu (Counter pointCounter, Counter pointCounter1)
{
counter = pointCounter;
counter1 = pointCounter1;
