I'm trying to hide all objects at once and I know about the "getImage().setTransparency(0);" method, but I do not know how to apply it to all of the objects. How could I do it?
// in world class for (Object obj : getObjects(null)) ((Actor)obj).getImage().setTransparency(0);
// from actor class, start with: for (Object obj : getWorld().getObjects(null))
