Really need help with multilevels

By Rockermaster, with 3 replies.
Last reply by davmac, over 12 years ago:

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

Is it possible to have a smaller world on top of a larger one?

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

just put the damaged app in the bin and download it again. That normally works for me when I get a damaged file or app

That won't help in that case, as Gatekeeper incorrectly states the app is damaged.

Uploading and discussing of the Greeps project is discourage on the site as it is used in competitions. Sorry, but you will have to figure this one out on your own.

Greenfoot Error java.lang.IllegalStateException

By Spgoodwin, with 1 reply.
Replied to by davmac, over 12 years ago:

The error pretty message pretty much explains the problem:

An attempt was made to use the actor's location while it is not in the world. Either it has not yet been inserted, or it has been removed.

Most likely, you've got some code which removes 'this' actor from the world, but then goes on and does something else which requires the actor's location.

Counting multiples in scoreboard

By kaciedy, with 13 replies.
Last reply by bonana, over 12 years ago:

still the font style to change... And I've got another problem with my own scoreboard. The scoreboard gets activated by actor z, whose score is not counted. The scoreboard should display the score of actor a, actor b and actor c. I tried to use a public static int scoreA / scoreB / scoreC in the classes of these actors and "actor a" + scoreA / "actor b" + scoreB / "actor c" + scoreC as a string in the scoreboard class, but it always shows a score of 0. Does anyone know how to fix it? (I'm sure you do ;-) )

How to make the ground keep scrolling?

By AnneMacaroni, with no replies.

I don't want to make a scrolling background b/c it's too confusing so I decided to make a scrolling ground, which is an object, to make it look like my actor is moving. How would I make it so that the ground (Ground.class) could keep remaking itself? However I want it so that there are gaps in between so the actor can jump over the gap. Please help. I tried many ways but it lags a lot b/c I used counters and the counter eventually got to big (greater than 2000....) <Code Omitted> I then called it in the world's act() method so that this would keep repeating itself. Anyway to make it better? or provide a scenario that has a scrolling object (ground)
