This was my first data pack attempt and I have since updated it slightly. This is meant for a specific map I'm working on, however, the loot table can be modified to whatever you want. This was made intended for mini-games and not for survival mode.


Features:

• Supply drops that fall from the sky
  
• Modifiable timer for how long it takes for a supply drop to arrive
• Toggles for the smoke flare and chat alert
• Modifiable single loot table
  

How to Use

• Run command "/function supplydrops:_dev/help" to receive a book that is used for initial setup
• The flare is meant to be distributed throughout a survival game map or sold by villagers for different game modes

Functions

• /function supplydrops:_dev/help

    A written book that contains all the functions as executable text

• /function supplydrops:_dev/give_flare

    Gives a "Supply Drop Flare" that will call for a supply drop when placed

• /function supplydrops:_dev/toggle_flare

    Turns on/off the smoke flare left from calling in supply drops

• /function supplydrops:_dev/toggle_message

    Turns on/off chat alert for incoming supply drops  

• /function supplydrops:_dev/modify_timer

    Gives you a chat prompt for customizing timer
    Can be edited using scoreboard commands:
      /scoreboard players set limit SupplyDrops_Minutes #
      /scoreboard players set limit SupplyDrops_Seconds #

• /function supplydrops:_dev/land_all

    Lands all pending supply drops

• /function supplydrops:_dev/uninstall

    Removes all scoreboards in case you wish to remove the datapack

Limitations

• The way I have it set up, the loot table is specific to my map (however it can be modified)
• Supply drops are limited to the 9-slots of a dispenser
  
• The flare is uncraftable
• There is no randomly spawning supply drop feature
  

Modifying Loot Table

• Navigate to "SupplyDrops\data\supplydrop\loot_table\"
• Open file "supply_drop_loot.json"
• Modify/replace existing loot table to fit your needs
