Yes; "new room()" creates a new world, though it bothers me that you've called it "room" and not "Room". Java class names should start with a capital... As you're creating a new room each time, and presumably the constructor re-initializes the enemies, the enemies will re-appear. To fix this, you have at least three options: 1) Add a new constructor to the room class, which allows passing in the enemies. Then, keep track of the enemies for the room even when you switch worlds. You probably will need to pass the information to each new world. 2) Do not create a new room each time, b

It's no problem, and the fact that you're new to this is why I gave you some advice about how to ask questions :) In general, the more information, the better. It shows that you're willing to put some effort in, and then people will be more willing to try and help you.

Hey USBest! If you still want to let your crocodile move in a perfect circle, check out this scenario from SPower: http://www.greenfoot.org/scenarios/4873

yess thankss now it works perfect :D

In your act() method for the Ball, you have a section that already starts like the following, but this is what I believe you need after you add 'brickColor' to the Brick class.. <Code Omitted>

Arrays are simple collection of objects of the same type (where all decendents of an object can be considered the same type .. like all subclasses of Actor). Typically, you declare an array like so: Base_Type Array_Name = new Base_Type; where Base_Type is the class name like Actor, String,etc Array_name is any legal java name length is the size of the array you what to create eg. String names =new String; // creates an empty array with 10 slots starting at 0 and going to 9 Or you can initialize the values at the time of de

What your teacher is suggesting sounds a bit like a bubble sort - if that is what he's getting at, I can provide code. It is, however, a very inefficient sorting method

for vertical scrolling, would you replace all X's with Y's and all Width's with Height's?

Oh fair point, I hadn't thought about the possible recursiveness of it. I suppose you could have a List of ac

thx, lol

Just create a world constructor to recieve the actor. Example (still using 'Arena', and adding actor Player class 'player'): 'Greenfoot.setWorld(new Arena(player));'.

Thanks for the help :) yep it was to do with file access xD it hated getting images from another folder such as /smurf/smurf1.png once I had exported it xD so stuck images back in /images/ instead of /images/smurf/ and it worked perfect ^^
