It is working fine now. Thanks heaps! :)

Oh Thank you now it works .

Danpost that last getWorld().removeObjects(getWorld().getObjects(playButton.class)); was perfect thank you sooo much needed that all day!! and I am trying to keep everything in one world.

THANK U SO MUCH YAY I CAN GET GREEN FOOT NOW!

To add an actor to the world you have to use the method addObject(Actor, int, int); Using this method you add an actor to the world at the coordinates you give the method (the int's). When you want to add an actor from another actor class you need to use getWorld().addObject(Actor, int, int); You can also look this up in the Greenfoot API. All mehtods are listed and described there.

Wow... now I get everything!!! NOW it all makes sense! Thank you!!! Also, I must admit that my Computer Science teacher at my school is really bad at teaching, so... this is how I normally learn things (using the internet frequently). So thank you for being awesome!

When you say 'one screen' to modify the car, if you meant 'one world', then the easiest thing to do is to pass the car to be modified to the world. In the 'choice world', save the Car object in an instance field declared with 'private Car car;'. In the 'choice world' constructor, save the Car object that was passed to it. Then, when a button is pressed, modify the car right then. To return to the main world, you can use 'Greenfoot.setWorld(car.getWorld());'.

Yes all images you use have to be stored in the images folder in your project.

Oh ok sorry.

The best of programming is, that there are (nearly) always multiple ways!

That makes sense, but then I think your question has already been answered? Use Kartoffelbrot's code and call changeImage() on each of the tiles you want to flip the image of.

Yes, master! ;D
