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
• Scoreboard keeping track of supply drops opened (supply_drops_opened_X).

How to Use

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

Functions

• /function supplydrop:help

    A written book that contains all function as executable text

• /function supplydrop:feather

    sets a chest at your feet with a supply drop flare-feather
    (I had an issue with the give command where a supply drop would get summoned)

• /function supplydrop:toggle_flare

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

• /function supplydrop:toggle_message

    Turns on/off chat alert for incoming supply drops  

• /function supplydrop:modify_timer

    Gives you chat prompt for customizing timer
    Can be edited using scoreboard commands:
      /scoreboard players set limit Minutes #
      /scoreboard players set limit Seconds #

• /function supplydrop:drop_now

    drops all pending supply drops

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
• Supply will be summoned when dropped on ground (hard to give to another player without a chest)

Modifying Loot Table

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