LoadingScreen: Fetching the Assets from Disk
With those classes at hand, we can now easily implement the loading screen. Listing 6-4
shows the code.

LoadingScreen
extends
Screen {
public
LoadingScreen(Game game) {
super

}
We let the
LoadingScreen
class derive from the
Screen
class we defined in Chapter 3.
This requires that we implement a constructor that takes a
Game
instance, which we hand
to the superclass constructor. Note that this constructor will be called in the
MrNomGame.
getStartScreen()
method we defined earlier.
