How to reset a World while the Program is running?
Greenfoot.setWorld(new MyWorld()); //with MyWorld being the class of the world you want to restart
I have tried it but it doesn't work, because it can't detect the world in which I am in and that set the world to the world in which I was before. If i do this it changes the world to one single world everytime. But the thing that I want is, that when you are in whatever world 3 or so and you than press the R key that you would get the world 3 and that when you are in world 5 you get world 5 and not the world that is pre set.
You would place the code in the world’s act method so it should be straight forward how to detect in which world you are and change the ‘new MyWorld()’ to part to whatever you need. Please show your code if you are still having trouble.
With different levels, you might need to do something like the following:
To override the method resetWorld, in each level subclass, use code similar to the following:
To give a way to reset the entire game, you could modify the empty resetWorld method in the superclass (line 13 above) as follows:
You can then call this method directly from this superclass, or you can use:
from any level subclass to reset the game.
// in superclass of the levels
public void act()
{
String key = Greenfoot.getKey();
if ("r".equals(key) || "R".equals(key)
{
resetWorld();
}
// other key detection codes here, if any
}
// to be overridden in each level subclass
protected void resetWorld() {}// in Level1 world, for example
protected void resetWorld()
{
Greenfoot.setWorld(new Level1());
}protected void resetWorld()
{
Greenfoot.setWorld(new MyWorld());
}super.resetWorld();
Thank you, now it works
