Copycats: Weight Tweak

by Faizan49

Copycats: Weight Tweak lets server owners set the mass of copycat blocks so Create Aeronautics airships fly as their builders intended.

NeoForgeServer-side onlyAll rights reserved1.21.1

What it does

Copycat blocks from Create are heavy by default, and in Create Aeronautics assemblies that weight can throw off the flight of a structure. The mod ships a tuned default configuration that brings copycat blocks down to a realistic weight as soon as it is installed, so no manual setup is needed before the first build.

Mass values can be changed in the in-game configuration screen, which is provided by Catalogue, or edited directly in JSON files. The mod registers custom data properties for the blocks, which is meant to prevent heavy block calculation glitches in flying structures. It runs on the server alone, so players join without installing it.

Installation needs Create Aeronautics and Create: Copycats+, and the mod requires Catalogue to be installed for the configuration screen to appear. Copycats: Weight Tweak is published for NeoForge 1.21.1, with 1.1.1 as the latest file. It is released under All rights reserved and is not open source.

Key features

  1. Pre-balanced defaults

    Copycat blocks receive realistic mass values from the bundled configuration as soon as the mod is loaded.

  2. Mass editing in game

    Weight values can be adjusted through a configuration screen rather than only by editing files.

  3. Airship physics control

    Mass properties of copycat block assemblies are set so that Create Aeronautics structures handle the way their designers intended.

  4. Glitch prevention

    Custom data properties keep heavy copycat blocks from causing miscalculated behavior in flying structures.
