Ultimate Roleplay Kit - Mail
by NoodleDoodle
Ultimate Roleplay Kit - Mail is a datapack that provides letters, parcels and stamps for sending mail between players on a server.
What it does
Written books can be turned into envelopes for sending letters to other players, and bundles serve as postal boxes that deliver packages. Stamps and covers change how a letter looks, and a closed envelope can be copied like a regular book, with the copy keeping the original design so materials are saved. A single smithing table recipe pairs paper with a designated item, and a book or bundle cover-specific item is shown in the same table. Items used on a written book contain text, and some items store other items inside them, the way a bundle does.
The pack is built for vanilla-style multiplayer servers. It adds roleplay-oriented resource textures that give certain items a new look, and a server-side in-game guide with a few challenge advancements takes new players step by step through mail creation, needing no outside resources. The items add no innate gameplay; they exist to enhance player interactions. Ultimate Roleplay Kit - Mail requires Ultimate Roleplay Kit - Resourcepack, which supplies the models and textures, and the datapack relies on the URK core resource pack to function correctly. The mod version still requires the resource pack.
