String Dupe

by BrickBoyMC

String Dupe lets a player turn one string at a crafting table into 64 back, a loop that a server owner can leave running for infinite string.

What it does

The mod places a string-duplication recipe on a crafting table, so a single string placed there returns 64 strings. Repeating the step produces string without limit. Because the change is about crafting output, it is a server-side effect: a server running it yields the dupe for any player who uses the table, and players connecting without the mod can still join.

Key features

  1. One string in, 64 out

    Placing a single string in the crafting table returns 64 strings in one step.

  2. Repeatable crafting loop

    The table can be used again and again, so string supply has no fixed limit.

  3. Datapack install

    Server owners add the mod by placing its datapack in the world's datapacks folder.

What the author says

This pack/mod is realy simple and will not lag you at all, not cheat for servers it only works on client AND server. To add this to your server simple put the datapack in the "datapack" folder.
