Worlds

Creating a world in the game

Share a new world as you create it, or promote a single-player world you already have.

Two ways, both without leaving Minecraft: tick a box while creating a new world, or take a world you have been playing on your own and share it as it stands. Both need a linked account, and both open the link screen for you at the moment you press the button.

Sharing a new world as you make it

A checkbox in the top-left corner of Minecraft’s own create-world screen, off by default, so a world is only ever shared because you said so.

Singleplayer → Create
Create New World
Share as Fragment (multiplayer-shareable)
→ coord.vgbnds.cloud

Create New World
Cancel
  1. The checkbox, reading Share as Fragment (multiplayer-shareable). The grey line under it names where the world would be registered, so that is never a surprise.
  2. Press Create New World as usual. If you are not linked yet, the link screen opens here and brings you back with the box still ticked.

Everything else on that screen behaves the way it always does. The seed, the world type, the game rules and the mods you have loaded are what the world is made from, and those mods become the world’s pack.

Promoting a world you already play

Select a world in the Singleplayer list and press Promote to Fragment in the top-left corner. That save becomes a Fragment with its history intact. Nothing is regenerated and nothing is moved.

  1. Promote to Fragment. Its tooltip tells you why it is unavailable when it is: nothing selected, already a Fragment, or you are at your cap.
  2. Select the world first. The button acts on the selected row, and stays greyed until there is one.

How to tell it worked

The button’s tooltip changes to Already shared as Fragment, and that is the whole of the feedback. No message, no chat line, no dialog. The reliable confirmations are:

  • The world is no longer in the Singleplayer list.
  • It appears on the dashboard, under your worlds.
  • Running /vbf sharelink inside it prints a link.

Where the world goes

  1. The gameIt leaves the Singleplayer list
    A Fragment is a multiplayer world, and showing it in both places would let two copies of it be opened in ways that fight each other.
  2. The gameNothing adds it to your Multiplayer list for you
    This is the gap worth knowing about. The world exists, you own it, and until you paste its link into Add Server it is not in any list you can see.
  3. YouTake the link while you are still inside
    /vbf sharelink prints it, and clicking the line copies it. Add it to your own Multiplayer list the same way your friends will.
  4. YouOr fetch it from the dashboard later
    The world's page carries the same link under Settings. Nothing is lost by quitting first; it is only slower.
You type/vbf sharelink

[VBF] your Fragment link: vbf:frag-brisk-otter-cedar-lantern

[VBF] friends paste this into Multiplayer → Add Server. It never changes.

Clicking either line copies it. The link never changes on its own.

What the world brings with it

The save
Stays where it is, on your disk, in the ordinary Anvil format. Other players get their own copy of it when they first join.
The mods
The mods you had loaded become the world’s stamped list, which is what joiners are shown and asked to match.
The settings
A world promoted from a save carries no game-settings record, so the dashboard’s settings panel may be empty for it. The world plays normally; there is simply nothing on the site to edit yet.
Who may join
Nobody, until you say. A promoted world starts whitelist-only, and the whitelist starts empty apart from you.

Undoing it

Delete the world from the dashboard. That frees the slot, and it sits in the trash for twenty-four hours first, so an accident is recoverable for a day. Your local save is not touched, and it becomes an ordinary single-player world again.

If you want to see Fragment saves in the Singleplayer list anyway, the mod honours VBF_SHOW_FRAGMENT_SAVES=on. Opening one that way plays your own copy without any of the sharing, which is a useful escape hatch and a poor habit.
