Pathfinding is a cool concept that is best visualized on grids, so that's why I decided to implement it in Minecraft.
This is a Minecraft plugin using the Paper API which visualizes different pathfinding algorithms on a 2D surface (for now). Developed and tested in Minecraft 1.17, may work in older versions.
It is my free-time project, and it's work in progress.
You can either try to build it on your own with Maven, or download the jar file from a release.
To build with Maven, run mvn clean package. The jar file will be in the target directory.
When you have the jar file, just drop it in the plugins folder
of your Paper server.
/help Pathfinding - view in-game help with all the commands.
/pathfinding - interactive, clickable and easy to use chat menu with all options and controls.
/algorithm - set the algorithm used to pathfind.
/selectblockplane <y-level> <x1> <z1> <x2> <z2> - select the plane corner coordinates where the pathfinding will take place.
/mode - set the drawing mode. You can choose from path, visits and all.
/start - start the search and drawing.
/speed - tweak the drawing speed (1 - 10). Default is 10 (20 blocks per second).
/clear - clear the plane. It is also cleared automatically before each search.
/getitems - get the blocks which you can use to build your own walls, mazes etc.
