Custom Item Merge

by C191239

Custom Item Merge changes the distance at which dropped item entities combine on a server, using a command that a server operator can adjust.

What it does

Dropped items in Minecraft merge into a single entity when they lie close together. Custom Item Merge lets a server operator change the distance at which that merge happens, which can reduce the CPU load of a busy world. Changes are applied with a reload of the item-merge settings, and the command is auto-completed in the chat.

The mod runs only on the server, so players join without installing anything. Builds are published for Fabric, covering 1.17 – 1.21.5, and it is released under the GNU General Public License v3.0 or later as open source.

Key features

  1. Adjustable merge distance

    The distance at which dropped item entities merge can be set higher or lower to suit the server.

  2. Lower CPU usage

    A shorter or larger merge radius is intended to reduce the processing cost of many separate item entities.

  3. Reload command

    Settings are applied with an item-merge reload command, which requires operator permission and offers auto-completion.
