    • and

      public static ResourceCondition and(ResourceCondition... conditions)
      A condition that passes if each of the conditions passes. Has ID fabric:and and takes one field, values, which is a list of resource conditions. If there are no conditions to check, it always passes.

    • or

      public static ResourceCondition or(ResourceCondition... conditions)
      A condition that passes if any of the conditions passes. Has ID fabric:or and takes one field, values, which is a list of resource conditions. If there are no conditions to check, it always fails.

    • allModsLoaded

      public static ResourceCondition allModsLoaded(String... modIds)
      A condition that passes if each of the specified modIds are loaded. Has ID all_mods_loaded and takes one field, values, which is a list of strings indicating mod IDs. If there are no IDs to check, it always passes.

    • anyModsLoaded

      public static ResourceCondition anyModsLoaded(String... modIds)
      A condition that passes if any of the specified modIds are loaded. Has ID any_mods_loaded and takes one field, values, which is a list of strings indicating mod IDs. If there are no IDs to check, it always fails.

    • tagsPopulated

      @SafeVarargs public static <T> ResourceCondition tagsPopulated(TagKey<T>... tags)
      A condition that passes if each of the tags exist. This does not check if those tags have any entries. Has ID tags_populated and takes two fields: registry, which is the ID of the registry the tag is for, and values, which is a list of the tag IDs to check. If there are no IDs to check, it always passes, including in cases where a nonexistent registry is specified.
      Type Parameters:
      T - the type of the tag values
      Implementation Note:
      Because tags are loaded after loot tables (and predicates/item modifiers), these resources do not support this condition. In those cases, this condition logs a warning and always fails.

    • tagsPopulated

      @SafeVarargs public static <T> ResourceCondition tagsPopulated(RegistryKey<? extends Registry<T>> registry, TagKey<T>... tags)
      Type Parameters:

    • registryContains
