Concept

env.json is a Minecraft Library introducing a new sub json file extension format, with the goal of
redirecting minecraft resources to other ones based on the environment context.

Implementations

env.json doesn't provide these redirections directly, but only the operations around env.json files
and their resource reload management.

There is currently two official implementations of env.json:

• Environment Driven Assets (EDA)

Mod Identifier: env-driven-assets.

Environments: Client

Applies env.json operations to Minecraft Vanilla asset types.

• Environment Driven Data (EDD)

Mod Identifier: env-driven-data.

Environments: Common & Server

Applies env.json operations to Minecraft Vanilla data types.

The env.json Format

[
  {
    "rules": [ // the primary set of rules, is an "any" type
      {
        "type": "sequence", // all rules in the sequence must pass
        "rule": [] // the rules
      },
      {
        "type": "any", // passes if at least one rule passes
        "rule": [] // the rules
      },
      {
        "type": "not", // reverses the rule
        "rule": { // the rule
          "type": "...",
          "rule": "..."
        }
      },
      {
        "type": "dimension", // passes if the current dimension matches this one
        "rule": "minecraft:overworld" // the dimension, can also be a tag
      },
      {
        "type": "biome", // passes if the current biome matches this one
        "rule": "minecraft:plains" // the biome, can also be a tag
      },
      {
        "type": "x_coord", // passes if the following operations on the x-axis are valid
        "rule": {
          "comparator": "==", // must be <, >, ==, <=, >=, =< or =>
          "value": "100" // must be an integer
        }
      },
      {
        "type": "y_coord", // passes if the following operations on the y-axis are valid
        "rule": {
          "comparator": "==", // must be <, >, ==, <=, >=, =< or =>
          "value": "100" // must be an integer
        }
      },
      {
        "type": "z_coord", // passes if the following operations on the z-axis are valid
        "rule": {
          "comparator": "==", // must be <, >, ==, <=, >=, =< or =>
          "value": "100" // must be an integer
        }
      },
      {
        "type": "submerged", // passes if the current context is surrounded by water or not
        "rule": true // true for "if it is submerged" and false for "if it is not submerged"
      },
      {
        "type": "sky", // passes if the context is above the sky limit, at or below
        "rule": "at" // must be "above", "at" or "below"
      },
      {
        "type": "water", // passes if the context is above the water level, at or below
        "rule": "at" // must be "above", "at" or "below"
      },
      {
        "type": "void", // passes if the context is above the void limit, at or below
        "rule": "at" // must be "above", "at" or "below"
      }
    ],
    "result": "minecraft:block/stone" // the redirected resource
  }
]

The file must be registered under this format: redirected_resource_name-redirected_resource_extension.env.json.

Usage For Developers

In your build.gradle

repositories {
    // ...
    maven { url 'https://jitpack.io' }
}

// ...

dependencies {
    // ...
    modImplementation "com.mmodding:env.json:${theMostBeautifulVersionYouCanFind}"
}

You can now get your EnvJson object from a Resource object thanks to ExtendedResource#of(Resource)#getEnvJson
or parse it with EnvJson#parse(Path) or EnvJson#parse(InputStream).
