LET ME DESPAWN


Let Me Despawn (LMD) is a Minecraft mod designed to address entity lag issues by modifying the despawn mechanics for mobs that have picked up or equipped items.

Key Features

  • Allows mobs with equipped items to despawn naturally
  • Preserves dropped items when mobs despawn
  • Configurable mob exclusion list
  • Server-side functionality (not required on client)

Functionality

In vanilla Minecraft, mobs that pick up or equip items become persistent and do not despawn naturally. This behavior can significantly contribute to entity lag, especially in modded environments with increased mob variety and spawn rates.

LMD modifies the despawn check to allow these mobs to despawn naturally, like any other mob. To prevent item loss, any picked up or equipped items are dropped when the entity despawns.

Note: Mobs named with a name tag will still be prevented from despawning naturally.


Configuration (Version 1.2.1 and later)

Config File

  • Location: config/letmedespawn.json
  • Reload command: /almanac reload

Commands

CommandDescription
/letmedespawn add <mobName>Add mobs to the config
/letmedespawn remove <mobName>Remove mobs from the config

Mobs added to the config will retain their vanilla behavior and not despawn after picking up items. All commands update the mob list in real-time, eliminating the need for game restarts or manual reloads.


Installation

This is a server-side mod and is not required on the client.

### Fixed - Trial spawner rewards can no longer be earned by waiting for the trial's mobs to despawn. Vanilla counts a mob that despawned the same as one that was killed, so standing nearby until the mobs despawned completed the trial and ejected its rewards without a fight. A trial spawner mob now never despawns while its spawner still counts it towards the trial. It can despawn once the spawner lets it go: it wandered more than 47 blocks away, the trial ended or reset, or the spawner was broken. Leftover trial mobs still despawn, so they don't pile up. - Trial spawner mobs saved before this update are matched to their spawner automatically.

### Changed - Settings now use **Dungeon Config** (bundled with Almanac). They are stored in `config/letmedespawn/letmedespawn.json5` and can be edited in game, with searchable mob and item pickers. The previous `config/letmedespawn.json` is imported automatically. - `/letmedespawn add` and `addPersistenceEnabler` now reject unknown ids instead of saving them, and suggest every entity type rather than monsters only. - Endermen carrying a block now drop it when they despawn instead of losing it. - Removed MobStacker-specific name handling: a mob with any custom name is treated as named. - Requires Almanac 1.26.10.2 or newer. ### Fixed - Picking up an item no longer clears persistence a mob already had. Structure mobs such as mansion illagers and ocean ruin drowned, name-tagged mobs, and mobs made persistent by commands or other mods now stay persistent. - Equipment from a dispenser now follows the despawn rules. Previously the dispenser made the mob persistent after LetMeDespawn had run. - Monsters are removed on Peaceful difficulty again, even while holding a persistence enabler item. - Mobs from spawners with custom spawn data and from configured trial spawners are now recognised, and the spawner origin is saved with the mob, so the spawner rules survive chunk reloads and server restarts. - Despawn hooks no longer use `@Redirect`, which conflicted with other mods hooking the same calls. ### Performance - Mob and item lookups compare registry ids directly instead of building strings, and the equipment slot list is no longer reallocated on every despawn check. - Removed an unused mixin and a duplicate persistence calculation on every item pickup.
