Setting Up Hardcore Milestones in an Existing World

If you are adding the data pack to an existing Hardcore world save, you need to run the setup command so the alternative rules and challenge criteria become active. First, ensure you have placed both this data pack and the base BlazeandCave's Advancements Pack into your world folder.

Running the Installation Command

Open your existing save in the game. Open your chat window and type the setup command:

/function blazeandcave:hardcore_install

Press enter to run it. This command sets up and activates the hardcore rules in your world. Once executed, the system updates your survival milestone checks so you can track your progress safely without risking accidental game over screens. You can now open your advancement trees and view the updated criteria for your single-life survival journey across every major dimension.
