Listing 3.1
A very basic game application
used for doing the things that are needed before the game application ends, such as
storing the updated high-score list, or closing the network connection. This means
that the basic set of methods to be supplied in an XNA game is (see also Fig.
3.1
):
1.
Initialize
: here we can perform initialization tasks such as opening a network con-
nection or setting up an input device;
2.
LoadContent
: here we can load all the game assets, such as sprites, sounds, or
other assets needed for the game;
