# maze-solver-go
|
||||
|
||||
## Introduction
|
||||
|
||||
This is a simple little maze solver made for fun and practise writing code in
|
||||
golang. This project is a complete re-write of another maze solver I've written
|
||||
in Java back in 2018 after the first semester of uni at EPFL. Needless to say,
|
||||
this version is _way_ better as I have written it now that I have my Bachelor's
|
||||
degree in Computer Science.
|
||||
|
||||
### Goal of the project
|
||||
|
||||
The goal of this side project was to deepen my understanding of path-finding
|
||||
algorithms, together with trying to create a good design, focusing on
|
||||
dependency injection and unit testing. It was very instructive.
|
||||
|
||||
Not to brag or anything, but the design was quite good, because after
|
||||
completing the following steps of the project:
|
||||
|
||||
- reading a maze;
|
||||
- solving it;
|
||||
- writing the solution to the file-system;
|
||||
|
||||
an idea came to my mind: add the feature of visualizing the progress of the
|
||||
solving algorithm by opening a window that displays the progress of the solver.
|
||||
Well, each module (readers, writers and solvers) were design to be as decoupled
|
||||
as possible, and it allowed me to implement the `visualizer` feature in only a
|
||||
couple of hours (which I was honestly not expecting).
|
||||
|
||||
## Dependencies
|
||||
|
||||
- `go` >= 1.21
|
||||
- `ffmpeg` (optional, for video visualization, see [visualization methods](#visulazation-methods))
|
||||
|
||||
## Usage
|
||||
|
||||
After downloading `maze-solver` from the
|
||||
[assets of the latest release](releases/latest "Latest release"), you can use
|
||||
it with the following arguments
|
||||
|
||||
| Short | Long | Default | Description |
|
||||
| ----- | ----------------- | ---------- | ----------------------------------------------------------------------------------------- |
|
||||
| -h | --help | | Print help information |
|
||||
| -v | --verbose | 0 | Verbose level of the solver, see [verbose levels](#verbose-levels) |
|
||||
| -i | --input | `maze.png` | Input file, can be a `.txt` or `.png` file |
|
||||
| -o | --output | `sol.png` | Output file, can be a `.txt` or `.png` file |
|
||||
| | --path-char-in | `' '` | Character to represent the path in an input text file. |
|
||||
| | --wall-char-in | `'#'` | Character to represent the wall in an input text file. |
|
||||
| | --path-char-out | `' '` | Character to represent the path in an output text file. |
|
||||
| | --wall-char-out | `'#'` | Character to represent the wall in an output text file. |
|
||||
| | --cell-size-in | 3 | Size of a cell (in pixels) for input file of image type. |
|
||||
| | --cell-size-out | 3 | Size of a cell (in pixels) for output file of image type. |
|
||||
| -a | --algo | a-star | Algorithm to solve the maze, see [solving algorithms](#solving-algorithms) |
|
||||
| | --visualize | | Visualizer the progress of the solver, see [visualization methods](#visulazation-methods) |
|
||||
| | --video-name | `sol.mp4` | Name of the output file if --visualize is set to 'video'. |
|
||||
| | --video-framerate | 60 | Framerate of the video if --visualize is set to 'video'. |
|
||||
|
||||
### Verbose levels
|
||||
|
||||
| Level | Description |
|
||||
| ----- | ------------------------------------------------------------------------- |
|
||||
| 0 | nothing printed to stdout |
|
||||
| 1 | print the total time taken by the solver (time of the main() function) |
|
||||
| 2 | prints the time the solving algorithm took to run |
|
||||
| 3 | prints the time taken by each section (reader, solving algorithm, writer) |
|
||||
|
||||
### Visualization methods
|
||||
|
||||
| Option | Description |
|
||||
| ------ | ---------------------------------------------------------------------- |
|
||||
| window | will give a live feed of the solver |
|
||||
| video | creates a video where each frame is a step the solving algorithm takes |
|
||||
|
||||
### Solving algorithms
|
||||
|
||||
| Option | Description |
|
||||
