Land Manager Mod 1.16.5, 1.12.2 (Manage Custom Sized Protected Areas)

Overview#

Land Manager is a utility mod designed to prevent griefing and manage territory on multiplayer servers. Unlike chunk-based protection mods, Land Manager allows for the creation of custom-sized cuboid areas. These areas can be defined by administrators and assigned to players, or claimed directly by players depending on server configuration.

The mod features a robust permission system, allowing owners to add members, toggle mob spawning, and control block interactions. It also includes a visual border system using particles to help players identify protected boundaries.

Items#

Land Manager adds a single essential item for area management.

Admin Tool

The Admin Tool is the primary instrument for defining protected areas. It is typically accessed through the Creative Inventory or via commands, as it is intended for administrative setup.

Function: Allows the user to select two points in the world to define a cuboid region.
Usage:
1. Right-click the first corner of the desired area.
2. Right-click the second (opposite) corner.
3. Upon selecting the second point, a GUI will appear.

Admin Tool Selection

Selection GUI

After selecting two points with the Admin Tool, the GUI prompts the user for:

Area Name: A unique identifier for the protection zone (alphanumeric and underscores only).
Vertical Expansion: An option to extend the protection from the bedrock (Y:0) to the sky limit (Y:255), ensuring the entire column is protected regardless of the initial selection height.

Mechanics#

Area Protection

Once an area is defined and claimed, it is protected against unauthorized players. By default, non-members cannot:

Break blocks.
Place blocks.
Interact with containers (chests, furnaces, etc.) if the interaction flag is disabled.

Claim Requests

If the server configuration permissions.claimRequest is enabled, players cannot claim areas instantly. Instead, using the /lm claim command creates a request that must be reviewed and approved by an operator (OP).

Visualization

Players can visualize the boundaries of a protected area using the /lm show command. This generates a temporary border of particles around the cuboid, allowing players to see exactly where protection starts and ends.

Area Visualization

Commands#

The mod uses the base command /lm (alias /landmanager). Commands are divided into User and Operator (OP) categories based on the server's permissions config.

`/lm areas [page] [regex]`	Lists all protected areas on the server.
`/lm claim [name]`	Attempts to claim the specified area (or the one you are standing in).
`/lm members add <player>`	Adds a player to your area, granting them build/break permissions.

Configuration#

The mod's behavior is controlled via a configuration file, typically located in the config folder of the server. Key configuration categories include:

Permissions
