<span id="Tile-Maps-1"></span><h4 class="subsection">2.3.4 Tile Maps</h4>
<p>A tile map is a scene created by composing lots of small sprites,
called “tiles”, into a larger image. One program for editing such
maps is called <a href="http://mapeditor.org">Tiled</a>. Chickadee has native
support for loading and rendering Tiled maps in the <code>(chickadee
render tiled)</code> module.
