Shard's Compat: Voltaic-Sable Compat

by sharddevs

Voltaic-Sable Compat is a server-side NeoForge patch that keeps Voltaic machinery working when it is carried by Sable physics airships.

NeoForgeServer required, client optionalMIT LicenseOpen source1.21.1 – 1.21.11

What it does

Sable sub-levels can be assembled from and disassembled back into the overworld, and Voltaic grid machinery does not always survive that transition. The patch addresses the duplicated blocks that appear when a physics object is disassembled, where an edge block can survive and a dropped item is created, and it repairs grid-connected power so machines keep working after the changeover between overworld and sub-level. A separate fix stops a dispenser from losing a stack item when a deployed item is subtracted from it.

Ballistix is optional. When it is installed, the patch also lets Ballistix launchers and turrets function while mounted on assembled contraptions, and its Ballistix-related fixes are skipped automatically when Ballistix is absent. The Voltaic and Sable fixes still apply. The mod is a compatibility patch that adds no blocks, items or recipes of its own. It is part of the Aeronautic Warfare modpack stack.

Sable and Voltaic are required dependencies, and the mod is for NeoForge only. Only the server needs to run it, while players may join without installing it unless they play single-player or with both mods on the client. Files are published for 1.21.1 – 1.21.11, and the mod is released under the MIT License, so it is open source.

Key features

  1. Duplicate block fix

    Stops edge blocks from duplicating and the matching dropped items from appearing when a physics object is disassembled.

  2. Power across sub-levels

    Keeps grid-connected power and machinery working through the overworld and sub-level changeover.

  3. Dispenser stack fix

    Stops a dispenser from losing a stack item when a deployed item is subtracted from it.

  4. Ballistix launchers and turrets

    Lets Ballistix launchers and turrets function while mounted on assembled contraptions, when Ballistix is installed.

Questions

Does Voltaic-Sable Compat need Sable and Voltaic?

Yes. Sable and Voltaic are required dependencies, and the patch must be installed alongside both.

Must players install the mod?

Only the server requires it. Players connecting to that server do not need it unless they play single-player or with both mods on the client.

Is Ballistix required?

No. Ballistix is optional, and its fixes are skipped automatically when it is absent, while the Voltaic and Sable fixes still apply.
