Datapacks

Structure

Data Attributes works using Minecraft’s data resource system. The file hierarchy for this is data/namespace/attributes. Where namespace is either the default minecraft or any given modid. By default, nothing exists in this directory, as all json data is optional. However, a fully populated directiory contains the files entity_types.json, functions.json, properties.json and /overrides/ (which is a folder). This takes the form shown below:

📂data
 ┗📂<namespace>
   ┗📂attributes
     ┣📂overrides
     ┃ ┣📄attribute_name.json
     ┃ ┗...
     ┃
     ┣📄entity_types.json
     ┣📄functions.json
     ┗📄properties.json

Before creating a datapack with Data Attributes, or using Data Attributes as a mod dependency, please familiarise yourself with Overrides, Entity Types, Attribute Functions and Attribute Properties.
