Sub-levels claim system for Create: Aeronautics
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.

How does it work?
You can claim Sub-level (ship, aircraft, whatever you want) with the Claim block using its GUI.
You also will have to use Aero claims depending on your Sub-level size.
You can acquire Aero-claims by converting regular OPAC claims to the Aero-claims
Each Aero-claim provides protection to certain amount of blocks (can be changed in config).
You can increase the claim size by adding more Aero-claims to Claim block.
Example:
- 1 Aero-claim = 50 blocks
- 20 Aero-claims = 1000 blocks

Feature
- You can place the Claim block only on Sub-level, it scans all the structure. Doesn’t work outside the Sub-level.
- You can set up permissions: party, ally, all or nobody.
- Simple GUI: claim-activation button, sub-level info, reload borders button. Press "refresh" button after you increased your Sub-level.
- Regular destruction and player-interaction protection.
- Improved create-block-interaction (drills, saws, deployers etc) protection. Protection from the honey glue (from Aeronautics). List will be improved, more items/blocks will be added.
- You can save the Sub-level list with all info as .json-files in the server folder. You can save claimed and unclamed “sub-levels” separately. Mod records sub-level’s - UUID & size, owner’s nickname. The list will be increased.
- Useful commands for admins and regular players. Admin commands provide the control over the amount of sub-levels, which can help with server optimization. The list will be increased.
- Set up with the config. The list will be increased.
