If you are wanting to find out what type an object is, then use the 'instanceof' keyword. See the bottom of this page of the java tutorials.

I do not see how the 'getOneObjectAtOffset' method has anything to do with adding music! Anyway, Greenfoot provides two ways to implement sound into your projects. One is through the static Greenfoot method 'playSound' and the other is by creating GreenfootSound objects and calling instance methods to control them. With the static method, you have no control over the sound; it will play once through and then stop (t will not loop) and you cannot pause or check to see if it is still playing or not.

Start by going through the tutorials in the documentation section.

That is called a block, or a block of code. A set is used to enclose the code for a class, others are used to enclose the code for methods and constructors, and still others are used to enclose the code for specific operations (such as 'if', 'while', 'do', 'for', 'switch', etc.).

You are most certainly correct. I wonder why jogit666 replied to it :0

No. All you have to do is call the method on a World instance.

You really need to give more background to your questions. Also, you should at least try something on your own and then, if you come across problems that seem to overwhelm you, post the code you tried with a brief description of what you were trying to do. Asking "How do I make a character shoot a bullet" leaves way to much to guesswork:

Try using 'move(-5)' before changing the rotation (see line 17 of the code Zamoht supplied). You may be able to remove 'oldEdge' from the code after inserting this line. However, I think it could still be buggy if both edges are encountered simultaneously. Maybe simplifying might help. Try this:

danpost: Thank you. I will investigate using the system clock - good one!

No. That is not what I meant. Use the scenario you got the Level class from as an example of how your 'map' array should be set for each level.

so just follow other highscore tutorials?

Thanks danpost and super hippo for the suggestions, dan yours is like what i was trying, but right! I will test the code in a bit and tell you.

Thanks I figured it out. Whenever I try to set an image by right clicking the class it will only accept images from outside the images folder of my scenario. When calling a method (like for animation) you can use images you've saved in the image folder.

There is a way to create an Actor object that displays a message without creating a new subclass of Actor. However, which ever way you go, you will have to deal with how to remove the actor after it is displayed (unless this will end that simulation). When using a class for it, you can check for the existence of an instance of that class in the world with 'getObjects(ClassName.class).isEmpty()'. This will work provided you have only one instance of the class present at a time. Any other situation (more than one instance or not using a separate subclass of Actor) will require a field be set
