background maps. By layering these maps so closer objects are in front of
distant objects, the feeling of depth is created. The designer then programs
these layered background maps to move at different rates to simulate the
movement you see in nature. The map closest to the player moves fastest. The
map farthest from the player moves slowest. Next time you play the classic
game Mario Brothers, look at how the backgrounds move behind the action.
You will build a game with parallax later in this course.
Two and one-half–dimensional (2.5D) games
have two-dimensional
background graphics, but uses three-dimensional (3D) characters and obstacles,
an example of which is shown in
Figure 4-23. This type of game
is a
hybrid.
The graphics are
designed with three dimensions
(length, width, and depth), but
the gameplay is still defined by
only length and width. This style
of game has 3D characters and
objects on a flat background.
In a true 3D game, objects are

CHEAT CODE: HYBRID
A hybrid is created by combining
features from two different items.
A hybrid car is a combination of an
electric car and a car with an internal
combustion engine. A 2.5D game is a hybrid because it
combines 2D gameplay with 3D objects.

This is a 2.5D game. The game frame is two dimensional, but the characters and obstacles
are three dimensional.
