Ok, fixed it now, thank you very much for your help!

You can use an int field in the world class to track which level you are in or you can use different worlds for each level.

Thanks for your help.

Ah, thank you.

What you are saying is: if soldYesterday is greater than soldToday, then salesTrend is assigned negative one else salesTrend is assigned one. If you know how to assign a value to a variable then these would be your 'trueStatement' and 'falseStatement' replacements and 'condition' is replaced with your comparison expression. Hope that helps. If you still cannot get it to work, post the code you have now for more help.

Whether you use a startup world or not, the sound in the main world will have to be initialized in that world. If you initialize the GreenfootSound fields and play each one after setting volumes to zero (to actually load the files) in the world constructor, they will be ready when the scenario is started (remember to reset the volumes back for each sound).

ok, Thanks a lot!

I got this working. Initialized space at the top then added space = (Space) getWorld(); space.countScore(1); to the asteroid class before the object is removed.

Okay, thanks for the correction.

Did you miss my abstract 'QnA' class posting of 2 days ago, also? If you look over the code, maybe you can get a better idea of how arrays work. A simple array is returned from the 'getChoices' method and is called from a statement something like the following: <Code Omitted>This will create a simple array, or list, if you will, of choices. 'choices' is the first choice, 'choices' is the second, and so on, ba

You may have some information tags in your sound file. Try re-saving the file making sure that they are not included.

I've already seen that one i want one which is a bit more advanced than that one but still teaches it to you as if you are a complete beginner but teaches to create a complete game from scratch

You might want to have one of the Greenfoot team members look at it. Or, you could upload it on the site, publishing the source code, so we could see what is going on.
