ASCII Masks

Explore how to create and apply ASCII masks to fit mazes into custom shapes. Learn to read mask files, interpret characters for maze cells, and implement masking methods in Ruby, enabling flexible maze designs without altering core algorithms.

Introducing ASCII masks

Imagine if we could “draw” our masks in a separate file and feed that file to our program. We could play with all kinds of designs without having to change our program at all! Let’s make that happen using simple text files as input. The text files will be formatted something like the following, which shows one possible definition of a 10x10 grid.
