Scheduled Airdrops

Command Description /airdrop schedule list List all scheduled airdrop tasks /airdrop schedule add <name> <time> <chance> Add scheduled airdrop task /airdrop schedule remove <name> Remove scheduled airdrop task

Parameter Description:

• time: Minecraft in-game time (0-24000)
• chance: Trigger probability (0.0-1.0, e.g., 0.5 means 50%)

Other

Command Description /airdrop particles Toggle airdrop particle effect display (client-side)

Scheduled Airdrop System

Scheduled airdrops allow the server to automatically generate airdrops at specific times.

Configuration Example

/airdrop schedule add morning 6000 0.3

This will trigger a 30% chance of airdrop at game time 6000 (noon).

How It Works

• The system checks all scheduled airdrop tasks every game day
• When game time matches, it decides whether to trigger based on set probability
• When triggered, airdrop spawns randomly within configured range

Airdrop Range System

Range Priority

1. World Border Integration (if border_weaver mod is installed)
2. Manually Set Range (via Range Limiter)
3. Random Around Player (default: player position ±100 blocks)

World Border Support

The mod automatically detects world borders, ensuring airdrops always spawn within bounds.

Loot Pool System

Loot Pool Concept

Loot pools are the random source for items in airdrop crates. Each loot pool contains 27 item slots, and a random pool is selected when an airdrop spawns.

Creating Loot Pools

1. Use command /airdrop edit <name> to open edit interface
2. Place items in the opened chest interface
3. Close interface to auto-save

Loot Pool Files

Loot pool configurations are saved in world data and can be backed up or shared via export functionality.

Mod Compatibility

Installation

1. Ensure Forge 47+ is installed (Minecraft 1.20.1)
