Chapter 4 Perspective, Scene Design, and Basic Animation
To make tile-based games easier to construct, many designers create and
share tile sets and sprite sheets.
Tile sets
are standard-size tiles arranged next
to each other on a single sheet as a single bitmap image.
Sprite sheets
are
similar to tile sets, except the sprite sheet is a single bitmap image of all the
frames of animation for a sprite movement, as shown in Figure 4-18. Only the
portion of the sprite sheet for the current animation frame is displayed at any
given time. A single sprite character may have several movements and thereby
have several
movement sets
included on a single sprite sheet. The tiles from a
sprite movement set are played to create frame-based animation.

A sprite sheet set like this can be used to create an animated character
or object, such as this character running.
Figure 4-17.
This is a tile map that
is 15 tiles tall and
20 tiles wide. The
location of each tile
is a coordinate on the
grid and a specific
tile is associated with
that location.
