Json Things

A mod that enables players to define blocks, items, and more... all via json!

 

 

Features

Json Things lets you define, via json files

  • Items (including food, tools, armor, block items, ...)
  • Item tiers (new tiers for tools)
  • Armor materials (new tiers for armor)
  • Creative Mode Tabs
  • Blocks (including slabs, stairs, fences, doors, ...)
  • Block Shapes (Voxel Shapes)
  • Block Sets (wood sets including stairs and fences, with their corresponding sounds)
  • Fluids
  • Enchantments
  • Sounds

 

TODO

  • Scripting (WIP)
  • ... feel free to suggest more!

 

HOW?

Json Things works via Thingpacks, which are similar to resource packs or datapacks. Thingpacks contain thing jsons, along with resources and data.

To install a thingpack, place it in the thingpacks directory in your game installation, or drag&drop it in the Json Things configuration screen.

You can also place a resource pack or datapack there, since the thingpack loader also adds the packs to the list of resourcepa ls and to the list of datapacks. Yes this means this mod works as a global datapack loader, even if unintentionally!

 

Documentation

If you want to create your own thingpacks, you can find the official documentation here. It's a bit barebones right now, but it describes the json files' structure as completely as I could.

 

Sandwood: A Json Things example pack

You can find the Sandwood example as an additional file in the release (look for the "+1 More" text in the Files page). I will try very hard to keep the sandwood example updated with the latest features, so it can work as a reference.

 

Thingpack folder structure

 

Can I use this in <X>?

Yes. Unless <X>'s license is incompatible with this mod's, which is unlikely.
