Modern TPA

Players send requests with the tpa command to reach another player, or with tpahere to pull that player to them. The request arrives as a chat message for the recipient, who can accept or reject it. A sender can cancel a request they have already made. Typing the trigger shows an autocomplete list of the available actions, and a player can be named directly to pick a target.

Two players who each send a matching request to the other have both requests accepted at once, so neither has to confirm. Accepting can also be done by clicking a message or through the command menu. The mod is a data pack, and it is published for Fabric, Forge, NeoForge and Quilt for game versions 1.21.11 – 26.2, with snapshot builds included. The server has to run it, while a player who lacks it can still join, so it works on the server alone.

The pack also works in a single-player world, but only once the world is opened to LAN, so the extra button needed for clicking on messages can be used. Adding the pack to a world marks it as experimental. Installing it removes nothing from the vanilla data pack, but deleting the tags folder for dialogs from the pack causes problems. The source code is public, while the mod is released under All rights reserved and is not open source.
