astar-visualization is just a simple tool to visualize the A* Pathfinding Algorithm and I built it in an attempt to learn the ropes of Golang. Below is a gif of the tool in action: (2x Speed)
- Click & drag around to create walls/obstacles.
- Click the
CHOOSE SOURCEorCHOOSE DESTINATIONbutton and click on any cell to mark them as the source/destination. - Click
RUNto run the visualization. If you run without choosing a source and destination, the visualization will not run. - Click
RESETat the end of the visualization to reset the board.
The visualization considers a diagonal step as a valid step. Keep that in mind when drawing obstacles as it may appear that the algorithm is bypassing the walls/obstacles.
astar-visualization is built with fyne, a cross-platform GUI library and hence can run on Linux, Windows & MacOS. However, I have only tested it on Ubuntu 19.10 and will provide instructions for the same.
Make sure you have gcc & golang(Version 1.11+) installed. Then run the following.
sudo apt install libgl1-mesa-dev xorg-dev
git clone git@github.com:parkerqueen/astar-visualization.git
cd astar-visualization
go run main.go
If you wish to run on Windows or MacOS or any other flavor of Linux, you can visit fyne's getting started to install all the prerequisites for it. Once done, you can clone the repository and use go run main.go to run the tool.
- Final help text of resetting the board is sometimes not displayed correctly.
