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)
