Terms
 Sprites: Two-dimensional bitmap images drawn on a transparent
background that are used to represent objects during game play. For
example, in a Pac-Man game, sprites would be used to represent Pac-Man
and the ghosts that chase him. Sprites can consist of any number of images
that are used to generate animation.
 Objects: A logical representation of an item in a computer game. Objects
provide the basis for creating things like ships, tanks, monsters, etc.
Resources in games that you control and interact with what playing.
 Instances: the representation of an object within a computer application.
One or more instances can be created for each object in a game. Instances
are generally, though not always, represented by sprites.
 Scripts: Collections of code statements that outline the programming logic
that controls the operation of object instances within games.
 Rooms: An area within a game where sprites interact with one another as
the game is played.
 Backgrounds: A graphic image used to decorate a room and provide it
with appropriate background scenery. Backgrounds can be tiled or
stretched as necessary to fill a room.
 Sounds: audio files (wave and midi files) played when events occur
during game play or played as background music in order to provide the
game with appropriate atmosphere.
 Paths: A predetermined directions and course along which are played.
 Fonts: Definitions that specify the type, size, and other attributes of the
fonts used to display text in games.
 Time Lines: Timers that execute predefine actions at predetermined
intervals during game play.
