Area Light Up

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)
