Fixed it, for those who need the fix getWorld().addObject(gameover, getWorld().getWidth()/2, getWorld().getHeight()/2);

MyWorld is a Class name and only shares its name as the type of objects it creates. In general (that is, without specifically programmed restrictions), a class can create multiple objects. Given two worlds: 
World mwA = new MyWorld(600, 400, 1);
World mwB = new MyWorld(800, 600, 1);
The use of the Class name (or Type of object) is not sufficient to distinguish what world instance you might, say, want the width of.
