i'm trying to make a pacman style game and the issue i'm having atm is with the ghosts turning too much/getting stuck. there a way i can do somthing like if within.1 of Wall.class turn?

In World_1: <Code Omitted><value> should be a data type.

Because the 'addObject' method is a World method, you need to qualify the method call with a World instance. In this case you can use the 'getWorld()' method to obtain a reference to such an instance. The code would look like this: <Code Omitted> This really should have be

In fact, the 'shields' array is an array of GreenfootImage, not of String. So this line: <Code Omitted> ... should not actually compile. Since you did not post the code for your Shield class, I don't know whether the constructor expects a string or a GreenfootImage parameter. Please use code tags to avoid the formatting issues that you have in your post.

It looks like you want to create a list with all cards in it. If it is this case, you can get a list of all cards with: <Code Omitted>

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:
