Advancement Generation

Advancements can be generated for a mod by subclassing AdvancementProvider and overriding #registerAdvancements. Advancements can either be created and supplied manually or, for convenience, created using Advancement$Builder.

After implementation, the provider must be added to the DataGenerator.

`Advancement$Builder`

Advancement$Builder is a convenience implementation for creating Advancements to generate. It allows the definition of the parent advancement, the display information, the rewards when the advancement has been completed, and the requirements to unlock the advancement. Only the requirements need to be specified to create an Advancement.

Although not required, there are a number of methods that are important to know of:

Method	Description
`parent`	Sets the advancement which this advancement is directly linked to. Can either specify the name of the advancement or the advancement itself if its generated by the modder.
`display`	Sets the information to display to the chat, toast, and advancement screen.
`rewards`	Sets the rewards obtained when this advancement is completed.
`addCriterion`	Adds a condition to the advancement.
`requirements`	Specifies if the conditions must all return true or at least one must return true. An additional overload can be used to mix-and-match those operations.

Once an Advancement$Builder is ready to be built, the #save method should be called which takes in the writer, the registry name of the advancement, and the file helper used to check whether the supplied parent exists.

// In AdvancementProvider#registerAdvancements(writer, fileHelper)
Advancement example = Advancement.Builder.advancement()
  .addCriterion("example_criterion", triggerInstance) // How the advancement is unlocked
  .save(writer, name, fileHelper); // Add data to builder
}
