📝 About

VisitUrFriends adds the Destination Book (German: Zielbuch). One player hosts, the other enters the invite code, and a Nether portal takes you to your friend's world. Going back is just as easy.

🚪 How it works

Host

1. Open your world and get a Destination Book (Tools & Utilities tab).
2. Right-click the book and press Host: Portal erstellen. An invite code is created and copied.
3. Send the code to your friend and throw the book into your Nether portal.

Guest

1. Right-click your own Destination Book, enter the code and press Gast: Code eingeben.
2. Throw the book into a Nether portal in your world.
3. Stand in the portal until it has charged. You will join your friend's world.

Going back: walk through any Nether portal in your friend's world to return to your own world.

⚠️ Good to know

• Meant for singleplayer worlds opened to LAN. Not for dedicated servers.
• The host's world must stay open while the guest is visiting.
• e4mc creates a new address every time a world is opened. Create a new code after each world start.
• To exchange invite codes, the mod contacts a small rendezvous server. Only the invite code and the e4mc address are sent.
• The mod contains no native code or bundled binaries.
