Traveler

Each player summons their own Traveler with the Traveler Compass, and only that player controls it. A Traveler can follow its owner, sit at a chosen location, or attack hostile mobs when that ability is switched on. Shift with right click toggles between following and sitting, and shift with left click toggles the attack behavior. Several skins can be picked with a left click.

Trades are handled by a custom progression system. A Traveler levels up, gains new offers and XP over time, and the trade stock restocks independently for each player. Progress is stored in three configuration files inside the config folder, named traveler-level1.json, traveler-level2.json and traveler-level3.json, and each file lists the items that become available as the Traveler advances. Nearly every part, including trades, combat behavior and progression, can be changed in those files.

Traveler is inspired by the Town NPCs of Terraria, especially the Guide, which follows the player and offers trades through a custom interface. It runs on both client and server. An integrated server and a dedicated server both need the mod, and any player who joins such a server must also have it installed. The mod is published for Forge only, with files for 1.19.2, 1.20.1 and 1.21.1, and the latest file is 1.1.0 for 1.21.1. The code is not open source, and the mod is released under All rights reserved.
