Survival-friendly datapack for Minecraft that adds an item magnet which attracts items to the wielder in a small radius.

Download here, put zip in your save's datapacks folder, then run /reload to install

Further Details

• I tried to document exactly how everything works via comments in the function files. Feel free to contact me with any questions.
• Regular chainmail leggings are unaffected and can be used normally.
• Teleports items to you in a 5 block radius.
  • Only one item entity at a time is teleported on purpose, so you can't 'carry' multiple stacks of item entities with you as you move like you can with many modded magnets.
• Makes all items in a 10 block radius play a quiet sound (in the "player" sound category) to help you find them.
  • Plays a quieter, pitch shifted version of the Experience Bottle Thrown sound, if you have captions enabled.
  • More item entities causes the sounds to stack and get louder.
• When allMobs_Laggy is enabled, any mob wearing a magnet in its legs slot or primary hand slot will have the magnet effect applied. Tested with zombies, skeletons, zombie pigmen, foxes, and villagers.

Credit

• I used an online tellraw generator to produce tellraw commands - those are a pain.
• Multiple stackoverflow, reddit, and minecraft forums posts explaining command behavior and nitpicky syntax were read in the process of squashing bugs.

Planned features (Eventually™)

• Offer a resource pack to clients that retextures the magnet item.
