No objects? You have to write code in your world's constructor to place the initial objects. (See some other scenarios for sample code.) In the exported version, we cannot interactively create objects...

I can see a greenfoot and a barrel appear seemingly randomly after I click the buttons a few times...

It keeps generating a nullpointerexception for me - it's hard to know what exactly is going on without the source to look at, but a good start would be to make sure that you're referring to all the images you're using in the right case and you've declared them all properly. If it helps you sort the problem, the console output I'm getting is: java.lang.NullPointerException at greenfoot.util.GraphicsUtilities.toCompatibleTranslucentImage(GraphicsUtilities.java:274) at greenfoot.util.GraphicsUtilities.loadCompatibleTranslucentImage(GraphicsUtilities.java:221) at greenfoot.GreenfootImage.loadURL(GreenfootImage.java:143) at greenfoot.GreenfootImage.loadFile(GreenfootImage.java:167) at greenfoot.GreenfootImage.<init>(GreenfootImage.java:70) at greenfoot.World.setBackground(World.java:152) at Mar.iniciaJuego(Mar.java:190) at Iniciar.act(Iniciar.java:24) at greenfoot.core.Simulation.runOneLoop(Simulation.java:199) at greenfoot.core.Simulation.run(Simulation.java:128) If you want to post the source, I and others might be able to help a bit more :) Also, what's the scenario meant to do?

Adding the with-source tag doesn't add the source automatically, you also need to select the "publish source code" check box.

The problem is the case sensitive filenames. You've got to refer to the file in the code in exactly the same case that it is in the directory, in this case your mar.JPG needed to renamed mar.jpg. If you do that and re-upload, it should work fine. Incidentally, the new version of Greenfoot (1.5) will warn you about this, which should make this problem disappear from the gallery once people use the new version! java.lang.IllegalArgumentException: Filename 'mar.jpg' has the wrong case. It should be: 'mar.JPG' at greenfoot.util.GreenfootUtil.checkCase(GreenfootUtil.java:547) at greenfoot.util.GreenfootUtil.getURL(GreenfootUtil.java:515) at greenfoot.GreenfootImage.loadFile(GreenfootImage.java:170) at greenfoot.GreenfootImage.<init>(GreenfootImage.java:75) at greenfoot.World.setBackground(World.java:176) at Mar.iniciaJuego(Mar.java:245) at Iniciar.act(Iniciar.java:16) at greenfoot.core.Simulation.runOneLoop(Simulation.java:286) at greenfoot.core.Simulation.run(Simulation.java:157)
