Replication Extended Registry

by Unfamily

Replication Extended Registry supplies matter value definitions for other mods' items, so Replication can use them in its recipes on NeoForge 1.21.1.

NeoForgeClient and serverMIT LicenseOpen source1.21.1

What it does

Matter values are defined in data files shipped with the mod, grouped by the mod that adds the items, under data/rep_ext_reg. Standard replication:matter_value recipes are loaded with the game alongside these entries.

Pack makers and server operators can set or replace matter values with no changes to any mod or datapack, because JSON scripts in a folder of their choosing are read after Replication has finished loading its defaults and attach values to single items or to item tags. The mod requires Replication and Titanium, and it runs on client and server, so both the server and every player need it. It is released under the MIT License as open source and is published for NeoForge only, for 1.21.1.

Key features

  1. Built-in matter value data

    Matter value definitions for several integrated mods ship inside the mod and load automatically.

  2. Per-mod folders

    Entries are grouped by the mod that adds the items, so each integration can be read or changed on its own.

  3. Script overrides

    JSON scripts in a configurable folder assign values to items or item tags and replace existing ones.

  4. Applied after Replication

    Custom values are applied once Replication has loaded, so they take effect without changing the Replication mod itself.

Use cases

Pack customization

Balancing recipes

A server owner can change the matter value of an item or tag to adjust what Replication recipes cost.

Who it’s for: Pack makers and server owners who run Replication on NeoForge 1.21.1 and want matter values for items from mods it does not already cover.

Questions

Does Replication Extended Registry need Replication installed?

Yes. Replication and Titanium are both required dependencies, so both must be installed with this mod on NeoForge 1.21.1.

Does the mod have to be installed on both sides?

Yes. Every player and the server need a copy of the mod.

Can matter values be changed without editing the mod?

Yes. Scripts in a configurable folder assign or override matter values for items and item tags, and they are applied after Replication loads.

What the author says

This mod ships built-in matter value recipes (Replication) for many mods and provides an external scripting system to register or override matter values without editing the mod. Under data/rep_ext_reg/recipe/matter_values/items/ the mod includes matter value definitions grouped by mod. These are standard Replication…
