Description

LightUp

Automatically places torches in dark areas within a radius around the player to prevent mob spawning. Uses an efficient grid-based placement system.

Commands

Command Description
/lightup Preview with default radius (64 blocks)
/lightup <radius> Preview with custom radius (8-128 blocks)
/lightup stop Stop the current task
/lightup help Show all commands

Features

Preview System

Before placing any torches, the mod scans the area and shows:

  • Torches needed with stack breakdown (e.g., "3840 (60 stacks)")
  • Inventory comparison (survival mode)
  • Crafting materials if you're short on torches
  • Click [START] to begin or do nothing to cancel

Game Modes

Mode Who Behavior
OP Mode Players with permission level 2+ Unlimited torches
Survival Mode Regular players Uses torches from inventory

How It Works

  1. Creates a grid of positions every 12 blocks apart (torch light reaches 14 blocks, ensuring overlap)
  2. Places ONE torch per tick to avoid server lag (~10 torches/second)
  3. After grid completion, does a cleanup scan for any missed dark spots
  4. Progress updates every 50 torches

Torch Placement Validation

A position is valid if:

  • Position is air
  • Block above is air (prevents underwater placement)
  • Block below is solid
  • Block light level is 0 (actually dark)
