pack.mcmeta

Format

• [NBT Compound / JSON Object] The root object.
  • [NBT Compound / JSON Object] pack: Holds the pack information.
    • [String][NBT List / JSON Array][NBT Compound / JSON Object] description: A text component that appears when hovering over the pack's name in the list given by the /datapack list command, or when viewing the pack in the Create World screen.
    • [Int] pack_format*: (optional) The main format of this pack.
    • [Int][Int Array] min_format: Specifies the minimum version supported. Can be a single integer or a list of two integers, where the first one is pack (major) version, second one a minor version. Specifying a single integer is interpreted as that major version, for example value 82 or [82] is equivalent to [82, 0].
    • [Int][Int Array] max_format: Specifies the maximum version supported, analogous as min_format. Specifying a single integer is interpreted as any minor version.
    • [Int][Int Array][NBT Compound / JSON Object] supported_formats*†: The major versions this pack supports. Has to match the major versions specified in [Int][Int Array] min_format and [Int][Int Array] max_format. Examples: 42, [42, 45], { "min_inclusive": 42, "max_inclusive": 45 }.
  • [NBT Compound / JSON Object] features: (optional) Section for selecting experimental features.
    • [NBT List / JSON Array] enabled: List of enabled feature flags.
      • [String]: Resource location of a feature flag.
  • [NBT Compound / JSON Object] filter: (optional) Section for filtering out files from packs applied below this one. Any file that matches one of the patterns inside [NBT List / JSON Array] block is treated as if it was not present in the pack at all.
    • [NBT List / JSON Array] block: List of patterns.
      • [NBT Compound / JSON Object]: A pattern.
        • [String] namespace: A regular expression for the namespace of files to be filtered out. If unspecified, it applies to every namespace.
        • [String] path: A regular expression for the paths of files to be filtered out. If unspecified, it applies to every file.
  • [NBT Compound / JSON Object] overlays: (optional) Section for specifying the overlays, which are sub-packs applied over the "normal" contents of a pack. Their directories have their own assets and data directories, and are placed in the pack's root directory.
    • [NBT List / JSON Array] entries: List of overlays. The order is important, as the first in the list is applied first.
      • [NBT Compound / JSON Object]: An overlay.
        • [String] directory: The directory to overlay for the respective versions (allowed characters: a-z, 0-9, _ and -). In this directory, pack.mcmeta and pack.png are ignored.
        • [Int][Int Array] min_format: Specifies the minimum version to apply this overlay on. See min_format in the pack section above.
        • [Int][Int Array] max_format: Specifies the maximum version to apply this overlay on. See max_format in the pack section above.
        • [Int][Int Array][NBT Compound / JSON Object] formats*†: The major formats to apply this overlay on. Must be present in all overlays if at least one of them requires it for backwards compability and has to match the major versions specified in [Int][Int Array] min_format and [Int][Int Array] max_format. Examples: 42, [42, 45], { "min_inclusive": 42, "max_inclusive": 45 }.
  • [NBT Compound / JSON Object] language: (optional) Only present in resource packs — Contains additional languages to add to the language menu.
    • [NBT Compound / JSON Object] Language code for a language, corresponding to a .json file with the same name in the directory assets/<namespace>/lang.
      • [String] name: The full name of the language
      • [String] region: The country or region name
      • [Boolean] bidirectional: If true, the language reads right to left.
