Hello everybody, Im almost done creating my scenario only im struggling with the last part of it, the winner image. I want a image to pop up after one of the two players reached 5 points first. I already started writing this code a little bit but i cant complete it myself. This is what i have so far: public void endGame) { Counter counter1 = (Counter) getWorld().getObjects(Counter1.class).get(0); Counter counter2 = (Counter) getWorld().getObjects(Counter2.class).get(0); if (counter1.getValue() >= 5) { Greenfoot.stop(); // code when player 1 reached 5 first } if (counter2.getValue() >= 5) { Greenfoot.stop(); // code when player 2 reached 5 first } -------------------------------------------------------------------------------------------------------- As u can see i already did a part of it. This is the way i want it to be, so i only need a code for an image to pop up when one of the players reached 5. I want greenfoot to load the image and not make another class with the name winner image. Can somebody help me with this last code? thank you

Let's say the image you want to display is called "player1Win.png". Well, you've got that part, but now you need to display it. Create a subclass of Actor, and call it ImageActor for easy use. Replace it's code by this:

import greenfoot.*;

public class ImageActor extends Actor
{
     public ImageActor(String fileName)
     {
         setImage(fileName);
     }
}

Now, do this when you want to display the image:

ImageActor a = new ImageActor("player1Win.png");
addObject(a, getWidth() /2, getHeight() /2);

you can image what to do when player 2 wins :) I hope this was helpful. EDIT: next time you want to insert code, click the 'code' button underneath the text field and enter your code there.

Thankyou for your response but i rather not want to create a new class. This because i make this for a schoolproject and i already handed in the documentation. So i cant change or add any classes, but as you can see in my code i already got a kind of code for the action. I just need a code which will be called on when the score is >= 5. And this code need to be a code in which an image gets called on the screen, just in your code an image is called on. I hope you understand me

Well, without new classes, the only thing you can do is this:

GreenfootImage img = new GreenfootImage("player1Win.png");
getBackground().drawImage(img,0,0);

But all the Actors will still overlay the image.

Or you can add the class at the bottom of the file, like this:

import greenfoot.*;

public class <Name> extends <Something>
{
    // your stuff here
}
private class ImageActor extends Actor
{
    // given stuff here
}

I think i will use your first recommended option. but im trying to compile it but it doesnt work. i created a new class with the name ImageActor but when i try to compile the second part a error shows it says: cannot find symbol -- method getWidth()

public void endGame()
    {
        Counter counter1 = (Counter) getWorld().getObjects(Counter1.class).get(0);
        Counter counter2 = (Counter) getWorld().getObjects(Counter2.class).get(0);
        if (counter1.getValue() >= 5) {
            ImageActor a = new ImageActor("carlos.png");  
            addObject(a, getWidth() /2, getHeight() /2);  
            Greenfoot.stop();
        }
        if (counter2.getValue() >= 5) {

            Greenfoot.stop();
            // code when player 2 reached 5 first
        }

I only wrote the code for counter1. The name carlos.png is the name of the picture i want to display can you tell what im doing wrong?

O, I'm sorry, I thought this code was in a subclass of world ;) Replace this:

addObject(a, getWidth() /2, getHeight() /2);

by this:

World w = getWorld();
w.addObject(a, w.getWidth() /2, w.getHeight() /2);

Since you been helping me, i was wondering if you could maybe help me with something else. As you know the max of points is 5 in my game. My ball needs to come back in the game till somebody have reached 5. I want to do this with a loop because using a loop is a must in my project.

   public void reset()
    {
        Bal oldBal = (Bal) getWorld().getObjects(Bal.class).get(0);
        oldBal.setLocation(438, 271);
    }

This code resets the bal once it is scored by one of the players. The new bal gets set on the location of the y and x Do you have a suggestion?

Well, a loop is certainly not in the right place here. A loop is meant to do thing multiple times, not something once :)
