Fixed it already thanks:) With Greenfoot.setWord(newFloodWorld(Menu.DijkDoorBraak.charselect) give a parameter. in FloodWorld. Public FloodWorld(int charselect)

thank you, it worked!

Change the calling method to the following: <Code Omitted>

yes I was, Thanks guys.

Shrug indeed...

You are probably calling the 'redCheck' method either before the Cursor object is placed in the world or after it has been removed. You could put a check as the first statement in the 'redCheck' method to avoid the error: <Code Omitted>

You need to declare an instance int field in the class to hold the speed for each object created and assign the random value (1, 2, 10, or 20) in the constructor of the object. <Code Omitted> if radNum=0: radNum/2=0, *9=0, +1=1; radNum%2=0, +1=1; 1*1=1 if radNum=1: radNum/2=0, *9=0, +1=1; radNum%2=1, +1=2; 1*2=2 if radNum=2: radNum/2=1, *9=9, +1=10; radNum%2=0, +1=1; 10*1=10 if

3D rendering is very difficult. There are actually many different ways to render 3D objects, but for all of them the algorithms are quite complex. If you're wanting to do 3D, Greenfoot isn't really a realistic option. You could try JMonkeyEngine (that was what I used when I first did 3D). If you're wanting to create a 3D rendering engine (I wouldn't personally recommend it, but it's up to you), then Google should help you out with what the algorithms actually are

Thanks

<Code Omitted> that's how I made it in my first game i hope this is what u asked for

First: class names should begin with a capital, and method names shouldn't. So, it should be "Level1" not "level1", and "addPoint" not "AddPoint". You want to be able to call addPoint regardless of whether the world is a Level1 or Level2, right? The easiest way is to make a new world class called eg ScoreWorld. You put the addPoint method in ScoreWorld, and you make Level1 and Level2 be subclasses of ScoreWorld. i.e. in Level1, where it says: public class Level1 extends World Change it to: public class Level1 extends ScoreWorld If you like, you can override the addPoint m

This is an easy. if (getX()>= getWorld().getWidth()-){ setLocation(getX()-,getY()); } The best way to do this is to have two variables for x and y movement. Example: xmove=0; ymove=0;. Then you should at the end of the script do setLocation(getX()+xmove,getY()+ymove);. For the left you would do if (getX()<= getWorld().getWidth()-). For Y, you must do if (getY() >= getWorld().getHeight()-) You get the Idea now, right? Not difficult at all
