I`ve created a Space Invaiders like game which changes levles when a certain score is reached but if it changes from level 1 to level 2, level 2 automatically freezes and i really dont know why. Thanks in Advance
Rocket Code
public class Rocket extends Movement

}

World FL = new FinalLevel();

}
public void World3(){
World W3 = new World3();
Greenfoot.setWorld(W3);
}
public void World4(){
World W4 = new World4();
Greenfoot.setWorld(W4);
}
;
