Hello, I've created a Paint application. I want it to have a save button that will over ride a file in my games library called default.jpg. Then I want the paint app I created to open the game (Flappy Bird). I want to do this so that default.jpg can be whatever the user drew. Is it possible to do this and how? Thanks, Arman

I think thats not Possible but when you add this Paint application as a class in the Flappy Bird Game before start the game you could save the new picture as A GreenfootImage in the world and load it from there during the game. I hope i could help you

Thanks @CooliMC! Your explanation helped me! Is there a way I can change the first world that appears in the game.

if you want to remove all the objects and paint then a new world for example called flappybird you should write a methode in the world called secondworld() { removeObjects(getObjects(null)); } and place the objects you want to add new after the ; in the methode and when you want to start the second wolrd you only must call this methode, Hope i could help you :D

add a methode to your wolrd: 
 secondworld() 
{ 
removeObjects(getObjects(null));
ADD YOUR CODE HERE
 }
and where i write add code you could write for example addObject or setImage or something like that , because with this methode you get a new and clear screen

@CooliMC: Wouldn't it be easier to switch the games world class? I have basically imported some of the code from the paint app and the flappy bird app into two worlds. I plan to do the order below when the user hits the play button on the drawing world: 1.Open new world (FlappyBird) 2. Add the users image that was drawn to FlappyBird world. 3. Allow the users to start the game. Is it possible?

Yes thats also possible but the order must be: when you want to get the secod world: 1.draw second world 2. in second world constucter: 
public class Secondworldname extends World
{
GreenfootImage DRAWNIMAGE;
public Secondworldname
{ 
Firstworldname bg = (Firstworldname) getWorld();
this.DRAWNIMAGE=bg.DRAWNIMAGE
}
...
}
3.delete the FIRSTWORLD I hope you understand it

You do not have to save the image to a file -- it is a GreenfootImage object referenced by a field (I will name the field 'image').. All you need to do is to create a reference to the new world when you create it. If 'GameWorld' was the name of your game world, then: 
GameWorld gw = new GameWorld();
creates the reference in 'gw'. From there you can execute method and access fields in the new world using the dot operator on 'gw' (for example 'gw.setBackground(image);' or 'gw.getPlayer().setImage(image);' or 'gw.player.setImage(image);'). After altering the world in the way you want, you can then make it the active world with 'Greenfoot.setWorld(gw);'.
