Adding and Naming Sprites
This section covers creating and naming sprites. In naming game assets, you should
follow a naming convention, which is a standard way of naming items. A naming convention
makes it easy to identify the proper game asset during game construction. These prefixes will
be used in asset names: SPR_ for sprites, OBJ_ for objects, SND_ for sounds, and BCK_ for
background images. For example, you may have a sprite named explosion and a sound named
explosion. By using a naming convention, you will be able to quickly identify the correct item.
