BuildMode

by YuWan030

BuildMode is a Forge server mod that protects build regions, limiting who can place or break blocks inside them and which items may be used there.

ForgeClient and serverMIT LicenseOpen source1.20.1 – 1.20.6

What it does

Server administrators define protected areas called build regions. Inside a region only authorized players can build, break blocks or use special items, and the item whitelist controls which items work there. Creative-only items can be restricted so they stay out of regions that are meant for survival or shared building.

Players standing inside a build region receive regeneration and absorption effects, and hostile mob spawning is blocked there, with monsters removed from the area. Region and whitelist changes are handled with in-game GUI screens and commands, and the data is kept in JSON files that can be edited by hand.

Permission checks work with LuckPerms when it is installed, and fall back to a standard operator check when it is not. The mod needs Minecraft Forge for the 1.20.1 – 1.20.6 range, and it runs on client and server, so the server and every player need it. Files cover six release versions, with 1.0.9 for 1.20.6 as the latest, and the code is open source under the MIT License.

Key features

  1. Protected build regions

    Areas are defined by administrators, and only authorized players may build, break blocks or use special items inside them.

  2. Item whitelist

    Only whitelisted items can be used within build regions, which keeps creative-only items with strong effects out of them.

  3. Region buffs

    Players inside a region gain regeneration and absorption effects while they stay there.

  4. Mob control

    Hostile mob spawning is prevented inside regions, and existing monsters are removed from the area.

  5. GUI and commands

    An in-game screen manages the whitelisted items, and commands handle region management.

  6. Editable JSON storage

    Regions and the whitelist are saved in JSON files, so they can be edited outside the game.

Use cases

Survival spawn protection

A server owner can mark a spawn area as a build region so that only trusted players alter it and no hostile mobs appear there.

Creative build zones

Builders can receive permission to work inside a region while creative-only items stay limited to that area.

Who it’s for: Server administrators who want to protect parts of a world and control which items players can use there, with a permission setup that can use LuckPerms.

Questions

Yes. Installation covers the server and each player's game.

Files exist for 1.20.1, 1.20.2, 1.20.3, 1.20.4, 1.20.5 and 1.20.6, all for Forge.
