EntityPathSeer
by Nullcoil
EntityPathSeer shows where each mob is heading by drawing in-world vectors that point to its current movement target.
What it does
A player toggles the Hitboxes view and sees the intended path of each entity, with vectors drawn in the world that mark the current movement target of every mob. The overlay lets a player follow wandering mobs and check where an AI routine sends them, which is useful when debugging behavior or planning a complex mob contraption.
Target positions are synchronized from the server to the clients, so the view stays accurate for every player in a multiplayer session. The mod is observational only: it changes no gameplay, and its performance cost is kept minimal. It is built for Fabric on Minecraft 1.21.4, and it runs on client and server, so both sides need it.
The code is available for inspection, and an issue tracker is open for reports. The mod is released under the Creative Commons Attribution Non Commercial 4.0 license, which is not an open source license. The first and latest file, 1.0.0 for 1.21.4, was published on 2025-11-02.
