Displaying a Maze on the Console
Explore methods to display mazes on the console using simple ASCII characters. Understand how to represent walls and paths, implement the to_s method in Ruby, and render maze grids clearly. This lesson makes maze visualization accessible without external libraries.
We'll cover the following...
Introducing ASCII art
ASCII art is not necessarily the fanciest way, nor the prettiest, but it is often the most convenient way to display our mazes. We nearly always have easy access to a terminal, and we don’t need to worry about bringing out any external libraries or APIs. In short, it’s perfect for what we need just now. Let’s walk through one possible way to approach drawing our mazes using only four different characters: space (“ ”) for cells and passages, pipe (“|”) for vertical walls, hyphen (“-”) for horizontal walls, and plus (“+”) to draw corners. An example of a small maze drawn using these characters is ...
