#
I have a program and if a player comes near a chest I want to give him extra lives and go to the next level. some times if you go to the next level I get an infinite loop.
?

public void act()
    {
        if(getObjectsInRange(50,Player.class).isEmpty() == false) {
           System.out.println("active");
           Player p = (Player) getObjectsInRange(50,Player.class).get(0);
           System.out.println("got player");
           p.lives+=lives;
           System.out.println("gave it lives");
           getWorld().removeObject(this);
           System.out.println("removed me");
           Greenfoot.setWorld(new RandomisedLevel(level+1));
           System.out.println("set the new world");         
        }       
    }
if I do
?
1
Greenfoot.setWorld(new RandomisedLevel(level+1));
manually it doesn't stop. and it prints all of the print statements this is the constructor of RandomisedLevel

    }
why does it stop ? why does it only stops sometimes ? how can I fixs this ?

I don't see where this is causing an infinite loop. Did you try to wait a minute? In the constructor of the Platform class, do you create the image manually? This could take a while if you create multiple platforms then.

Are you getting an error message when it stops? if so, what is it? (copy/paste in entirety)
