Copycats+ aeronautics weight

Name: Copycats+ aeronautics weight
Author: Mc_Orion

Copycats+ aeronautics weight is a NeoForge compatibility mod that gives Copycats+ blocks mass values for the Sable physics library used by Create: Aeronautics.

NeoForgeClient and serverMIT License1.21.1

What it does

Copycats+ blocks carry no mass that Sable can use, so ships built from them behave unrealistically. This mod assigns each block from Copycats+ a reasonable mass in kilograms, and copycat layers scale their mass with the number of layers placed. The mass values let copycat builds in Create: Aeronautics respond to weight the way other blocks do. Installation requires Create: Copycats+ and Sable, and the mod runs on client and server, so both the server and every player need it. Files are published for NeoForge 1.21.1, with version 1.1.1 as the latest file, released under the MIT License but not open source.

Key features

Mass for every copycat block
Each block added by Copycats+ receives a mass value, so no copycat piece is left weightless in a ship.
Layer-based mass
Copycat layers gain mass in proportion to their layer count, so a taller stack weighs more than a single layer.
Sable physics support
The mass values are read by the Sable physics library, which Create: Aeronautics uses to simulate ships.

Questions

Does Copycats+ aeronautics weight need Sable?

Yes. Sable is a required dependency, and Create: Copycats+ must also be installed next to it.

Do players and the server both need this mod?

Yes. A server running it needs every connecting player to have it too.

What the author says

This mod adds reasonable kpg (mass) to copycat+ blocks for the Sable physics library (create aeronautics etc). It includes kpg for all blocks from copycats+ including ones like copycat layers where more layers equals more kpg.
