This is an exercise used for a tutorial on backtracking for SCS Concordia. Students must implement the solve() function and fill the path variable with the solution to the maze.
This is just a simple random maze generator and solver I wrote for fun that gets drawn over a canvas on the page. It is fully written in JavaScript and tested with Jasmine.
Please feel free to fork and make comments/suggestions! Thanks!
The maze is generated using a Graph structure and a recursive depht-first search algorithm. All graph nodes (cells) are connected by default. By connected, I mean there is a wall separating them in the maze. As we run the DFS algorithm to generate the maze, we start removing connections and store them in an array of removed edges in the Graph class.
The size and complexity of the maze can be configured setting different width/height for the canvas element and setting the horizCells
and vertCells
numbers in the Maze class.
We're using the A * Search Algorithm to find the shortest path from the start to the end of the maze. We're assuming the start cell is always the top left one, and the end is the bottom right. You can change that, however, if you like.
