A* Pathfinding

by CJDev

A* Pathfinding gives mobs and entities a shared A* path search, exposed through a function that finds a route to a destination for the mod's entities.

What it does

The mod provides entities that follow A* routes and a function that finds a path to a given destination. The server must run it, while players may add it for their own client but are not required to. Files are published for Fabric, Forge, NeoForge and Quilt, covering 1.21 – 26.3 (17 release versions), with snapshot builds available, under the GNU General Public License v3.0 only, which makes it open source.

Key features

  1. Pathfinder entities

    Entities that move along computed A* routes through the terrain around them.

  2. Destination pathfinding

    A function that searches for a path from an entity's position to a chosen destination.

  3. Command chain limit

    Path search terrain can be restricted to a maximum of 10 blocks; setting maxCommandChainLength high enough is recommended, or temporary markers remain once the limit is reached.

What the author says

I recommend setting the maxCommandChainLength gamerule high enough for your terrain, or restrict the path to a maximum of ~10 blocks — otherwise, temporary markers may stay once the limit is reached You may add a function to the #astar:eval_node tag to modify costs — return results in only impassable being effective\…
