Mega Torch

Mega Torch adds a craftable torch that blocks natural mob spawning in a large area around it. Everything can be adjusted in game, and the config file is fully commented.

Features

• Blocks spawning inside a radius: 96 blocks by default, adjustable in game between 16 and 256.
• Three zone shapes: sphere, cylinder (protects caves at any depth) and cube. Each torch has its own shape.
• Change radius and shape while looking at the torch: keys ] and [ for the radius (Shift for bigger steps) and \ for the shape. Right-click with an empty hand to see the border drawn with particles.
• Choose what gets blocked: mob categories (monsters, animals, aquatic, ambient), spawn reasons (natural, chunk generation, patrols, spawners, events, golems, reinforcements...) and a per-mob whitelist and blacklist with tags and wildcards.
• Radius and shape stay with the item when you break the torch and place it again.
• Server tools: /megatorch list opens a chest menu with every torch (who placed it, coordinates, click to teleport), plus reload and purge. Changes can be restricted to operators and creative players, or to the player who placed the torch.
• Lightweight: the check run on every spawn attempt allocates nothing, and the decision for each mob type is cached.

Crafting

• Top row: gold block, glowstone block, gold block
• Middle row: gold block, torch, gold block
• Bottom row: diamond block, obsidian, diamond block

Commands

• /megatorch radius add <n> and /megatorch radius set <n>: change the radius of the torch you look at.
• /megatorch shape next|previous|sphere|cylinder|cuboid: change its shape.
• /megatorch list [page]: chest menu with all torches (operators and creative players).
• /megatorch reload: reload the config without restarting (admins).
• /megatorch purge: remove stale entries from the registry (admins).
• /megatorch restrict true|false: limit radius and shape changes to operators and creative players (admins).

Configuration

Two files in config/: megatorch-server.json (radius, shape, mob categories, spawn reasons, lists, display) and megatorch-client.json (keys). Both are commented in English and Spanish, and new options are added to them automatically. If a file has a syntax error it is not overwritten: the error is printed in logs/latest.log and, with /megatorch reload, the previous configuration is kept.

For public servers, consider enabling restrict_change_to_ops_and_creative and only_placer_can_change.

Notes and limitations

• Mobs that come with structures when a world is generated (villages, temples...) are not blocked.
• Patrols, events, golems and reinforcements are detected when the mob enters the world. This part is experimental.
• Other mods that spawn mobs through unusual paths may bypass the torch
