An A* (A-star) pathfinder in Python.
I am creating this to learn more about Python and the plan is to create 3 applications using different libraries to handle things in different ways.
I also added a simple benchmark to test how quick the pathfinder can be.
Because I am doing this for learning, I published this repository after the first commit, when nothing was finished yet. The idea is to share the whole progress with others and eventually to get feedback along the way.
Currently all the applications are feature complete and seem to work fine. Feel free to create an issue if you spot any bug or if you want to request a new feature.
This is the first version of the pathfinder. It's a CLI (Command Line Interface) application that loads a map from a file passed as argument, then prompts the user for a start and a goal cell and finally shows the path.
Current status: Done
$ python3 pyfinder.py data/maps/map_01.map
A visual application based on pygame.
Current status: Done
$ python3 pg-pyfinder.py data/maps/map_01.map 60
Second parameter is optional and it defines the size of a cell of the map in pixels (default is 30).
To search for a path simply click on the map twice.
After a path is visualized click one more time to clear it.
In the following image you can see what happens when no path can be found:
A visual application based on Qt for Python.
Current status: Done
$ python3 qt-pyfinder.py
After starting the application load a map from the menu File > Open Map:
It's possible to configure several options from the menu File > Options:
A simple benchmark to verify how quick pathfinding is, on average.
Current status: Done
$ python3 pyfinder-bench.py data/maps/map_01.map
Currently a map is a text file which contains 2 possible symbols:
- ' ' = walkable cell
- '#' = unwalkable cell
Map cells start from (0, 0) which represents the first characer of the map file.
Examples of map files can be found in data/maps/
