Create Aeronautics: Claims
by Mapter
Create Aeronautics: Claims lets players protect the sub-levels of their Create ships and aircraft, using a Claim block placed on the structure.
What it does
The Claim block works only on a sub-level, so the structure is scanned before a claim is set up. Claims are paid for with Aero-claims, and each Aero-claim covers a fixed number of blocks set in the config: one Aero-claim covers 50 blocks and twenty cover 1000. A larger sub-level can use more Aero-claims, and the claim grows as more are added to the Claim block. Regular OPAC claims can be converted into Aero-claims.
The mod keeps protection in place for Create blocks, including drills, saws and deployers, along with honey glue, while regular destruction and player interaction are also blocked inside the claim. Permissions are set through a simple GUI, where a party can be given ally access or left with nobody. A claim-activation button, a sub-level info display and a border reload button sit in the same interface, and after a sub-level grows, a refresh button updates its claim.
Create Aeronautics: Claims requires Open Parties and Claims and Valkyrien Skies. It works with Sable, and is compatible with OPAC and FTB claim systems. It is published for Forge and NeoForge for 1.20.1 and 1.21.1, is licensed under the MIT License, and is not open source.
Key features
Sub-level claims
A Claim block protects a whole sub-level, whether it is a ship, an aircraft or another Create build.
Aero-claim budget
Protected area depends on the sub-level size, and the claim can be enlarged by adding more Aero-claims.
Claim GUI
Permissions, party allies and the claim border are managed from a simple interface with refresh and reload buttons.
Admin commands
Server admins get commands to control how many sub-levels are claimed, which helps with server optimization.

What the author says
Works and compatible with Open Parties and Claims mod (OPAC). This is custom claim system, separate from OPAC, but integrates with its parties and allies system and claims amount. Players wouldn’t feel big difference between OPAC and our claim system.
