Counter
Import the counter class, add a counter object to the world. Whenever an item is collected, call the 'add' method (or how it is called in the Counter class) on the counter object which is in the world.
import greenfoot.*;
/**
* This class Level1 displays the first level for the user to play.

public class Level1 extends World
{
Counter counter = new Counter ();
/**
* Constructor for objects of class Level1.
*
*/
public Level1()
{
// Create a new world with 600x400 cells with a cell size of 1x1 pixels.
super(950, 700, 1);
//Making background fit the screen
GreenfootImage Bg = new GreenfootImage ("background.jpg");
Bg.scale (getWidth (), getHeight ());
setBackground (Bg);
//Adding the platforms
Platform platform = new Platform ();
addObject (platform, 268, 653);
Platform platform1 = new Platform ();
addObject (platform1, 704, 652);
//Adding characters
addObject (new MrKrabs(), 93, 522);
addObject (new Plankton(), 208, 490);
//Adding object for Mr. Krabs to collect
KrabbyPatty krabbyPatty = new KrabbyPatty ();
addObject (krabbyPatty, 484, 457);
addObject (counter, 100, 100);
KrabbyPatty krabbyPatty1 = new KrabbyPatty ();
addObject (krabbyPatty1, 842, 480);
//Adding object for Plankton to collect
FormulaBottle bottle = new FormulaBottle ();
addObject (bottle, 329, 374);
FormulaBottle bottle1 = new FormulaBottle ();
addObject (bottle1, 691, 436);
//
}
}
that is my code. I think I imported it wrong
Well, your code is not showing the Counter class. You added the counter correctly.
So how do I do that? I'm new to this lol
You need a Counter class that extends the Actor class. You can create one or you can import the one greenfoot supplies using 'Edit>Import class...' on the menubar and selecting it.
I got it. thank you. Where should I add the counter object? Line 40?

Please & thank you
In the act method of the class which should remove objects from the other class: (Change ClassName to the name of the class which should be removed.)
if (isTouching(ClassName.class))
{
removeTouching(ClassName.class);
((Level1) getWorld()).counter.add(1);
} if (isTouching (KrabbyPatty.class))
{
removeTouching (KrabbyPatty.class);
((Level1) getWorld()).counter.add(1);
}
}}Show the Counter class.
