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.

I created a 'Pause' world that when instantiated will create a background image of the current visual state of the calling world. Even though the initial world is not being viewed, it appears as though it is. Also, when setting a new active world, the old world is paused; so, the background of the new world would continue to be the actual view of the initial world until that world is returned to. I added an actor 'Panel' class to the scenario, and had one Panel object added to the 'Pause' world which displays the world 'GAME PAUSED' and 'CLICK TO RESTART'. When clicked on it displays a cou

That is not good. I hope that you are the only one experience that problem.

We know that the code supplied is alright (except for the missing semi-colon at the end of the 'turn' statement). You will have to supply more information and code to solve your problem. Code to supply: the 'atWorldEdge' method; specifying what class it is in the declaration statement of the class which the calling statement (supplied above) is located the entire method that the code supplied above is in the trace from the act method to the method that the supplied code is in (i.e. act>moveAndTurn>move; method-to-method)
