hEndermanFix

hEndermanFix is a lightweight Paper/Purpur plugin that fixes Enderman targeting behavior around Endermites.

The plugin automatically tracks Endermen and Endermites, finds the nearest valid Endermite within a configured radius, and keeps Endermen targeting it. It works automatically after startup and does not require commands, permissions, databases or external plugin dependencies.

---

Overview

hEndermanFix has one focused job: keeping Endermen properly locked on nearby Endermites.

When an Endermite appears, the plugin registers it and checks nearby Endermen. When an Enderman appears, the plugin registers it and searches for the closest valid Endermite in the same world. If a valid Endermite is found, the plugin sets it as the Enderman target.

The plugin also scans already loaded entities on startup, so existing Endermen and Endermites can be handled after a server restart.

Targeting

The plugin keeps a lightweight runtime list of tracked Endermen and Endermites.

During each check cycle, hEndermanFix:

1. Verifies that the Enderman is still valid.
2. Searches for the nearest valid Endermite.
3. Checks that the Endermite is in the same world.
4. Checks the configured target radius.
5. Forces AI and aware state if enabled.
6. Sets the Endermite as the Enderman target.
7. Removes the Enderman from tracking after too many missed checks.

The repeating task stops automatically when there are no tracked Endermen left.
