Chunk Claims

Similar to FTB Chunks, Chunks Claim allows you to keep other players out of your builds, and play together with teams and allies, all from two buttons in your inventory. No commands to learn.

Features

• Claim map: press M or click Claims in your inventory to see a 15×15 map of the chunks around you. Click a chunk to claim it, and click it again to give it up. Every claim shows in its owner's color.
• Protection: other players can't break or place blocks, use buckets, open doors and chests, or hurt animals and item frames in your claims. Explosions can't damage claimed land, and bedrock marks the corners of each claimed area.
• Teams: up to 4 players. The owner invites and kicks members, picks the team's claim color and decides whether teammates can hurt each other. Teammates can build in each other's claims.
• Allies: ally any player, in a team or not. Choose what allies can do in your claims: build, use things or hurt animals (in a team, the owner decides). Players who have allied each other can't fight unless both sides turn ally PvP on.
• Entry messages: "Entering Steve's claim" shows above your hotbar as you walk in.

For server owners

• Set the claim limit (25 chunks per player by default), team size, each protection, bedrock corners, entry messages and claimable dimensions in config/chunkclaims.json.
• Claimed chunks are never force-loaded.
• Operators can remove any claim from the map, and switch that on or off for themselves with /claimoverride.

Compatibility

• Chunk Claims also works with Lifeline, a lives mod I'm also making with Claude.
• There should be no issues with other mods, but another claims or land-protection mod would overlap with this one. Let me know in the comments if you find any problems.

Requirements

Minecraft 26.3 with Fabric Loader and Fabric API, on the server and on every player's game. Players without the mod can't join (server owners can turn this off with requireClientMod in config/chunkclaims.json).

• The mod doesn't work on 26.4 snapshots yet.

AI Notice

This entire mod was made with Claude AI in VS Code, so there may still be some issues. Let me know in the comments. (This description was also made with Claude, and I've gone through it to make sure everything is correct.)
