· 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.
