Conditions for new level
Well, I'm making a game in which you play as a teddy bear who has to gather honey (i was stuck for inspiration and smene had a winnie the pooh shirt on!) and i need to change levels when yu collect all the honey. how do i do this?

Okay so here is one way to go around it.
Code for a world that constantly checks for the amount of collectable honey left. When there is no honey left it sets up a new level.
import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)
import java.util.List;
/**
* Write a description of class HoneyWorld here.
*
* @author (your name)
* @version (a version number or a date)
*/
public class HoneyWorld extends World
{
int level;
/**
* Constructor for objects of class HoneyWorld.
*
*/
public HoneyWorld()
{
// Create a new world with 600x400 cells with a cell size of 1x1 pixels.
super(600, 400, 1);
setupLevel(1);
}
public void setupLevel(int lvl)
{
removeObjects(getObjects(null));
level = lvl;
if (level == 1)
{
//Add objects for the first level.
}
else if (level == 2)
{
//Add objects for level 2.
}
}
public void act()
{
//Change Honey.class to whatever name you use.
List honey = getObjects(Honey.class);
if (honey.isEmpty())
{
setupLevel(level+1);
}
}
}
great! only now the world doesn't appear at all... It's just a blank screen. It compiled all right but there is nothing. can anyone help with this?

Did you add any code to where I commented "Add objects for the first level." ? Because if there is no Honey class in the world, it will change to the next level.
Hi, DoctorProfessorYoshi,
I just wrote a similar game program. It's a modification of Wombat, who has to push a loaf into a house to complete a level. In this moment I write only an abstract, if its not clear enough, ask more.
Each level is a World, for example WombatWorld, IceWorld, WaterWorld, NightWorld......
The Actor classes are Wombat, House, Rock, Barrel and Loaf.
Wombat is moved by arrow keys, Rocks and the House are fixed, the Loaf and the Barrels can be pushed by Wombat. These the only classes and are used in all levels.
Within the Wombat class there is:
Within the constructor of the XxxxWorld is:
// otherwise ALL worlds will be run thru
Further on in the code, when the loaf reaches the house:
Within the act methode of the World :
The only thing I change from level to level is the image of the characters in the different worlds and within the creator how many rocks and barrels are there to create the difficulty of the level.
I hope this helps
greetings tollpatch
private boolean atGoal = false;
public setAtGoal ( boolean worldsend)
{ atGoal = worldsend;}
public getAtGoal ()
{ return atGoal;}wombat.setAtGoal (false);
wombat.setAtGoal(true);
if (wombat.atGoal)
{
Greenfoot.setWorld(new IceWorld()); //Only one world has control in a time
}@tollpatch your code will work for sure, but if you have like 100 levels, you have to create 100 world classes which is a lot of work (and it will fill a lot in your Greenfoot project and make it hard to read). If you on the other hand wants to create a game with less than 10 levels this is a good way to work around the problem.
Still nothing. I even added a new freakin' world but nothing, just a gray screen where the world should be. Everything compiles fine, there is honey in the world, but nothing happens, just the endless gray...

Could you please send some code or upload the scenario because I tested my code and it works fine.
this is the code for the world

Okay two things I don't get. First of all you put setuLevel(1); in the bottom of your level 1 code, which means that it will just run in an endless loop. The other thing is that in your act method you should change setuLevel(level=1); to setuLevel(level+1);
This should fix it.
Thanks!

Dang it! still nothing, Just gray, gray, gray...
