Disable Dimensions

A hard-to-break, grief-resistant solution for preventing players from entering The Nether and/or The End.

Allows you to disable dimensions by removing any possible way for players to enter them. Each dimension can be separately enabled or disabled.

Perfect for vanilla and modded multiplayer servers where you want to disable further dimensions to prevent players from progressing too fast.

Why use this data pack/mod?

1. Only Complete Solution:
   No other data pack currently disables both the Nether and the End for the current Minecraft versions.
   All older ones are outdated or broken.
2. Comprehensive Coverage:
   Works in every situation. For players in all game modes, teleportation commands, ender pearls, minecarts, and more.
   Players can enter portals/teleport, but are instantly teleported back. From the Nether to their entry point with a fallback to world spawn, and from the End to their respawn point or world spawn. See Edge Cases for the handful of scenarios that require manual cleanup.
3. Intended Vanilla Reward:
   Players who try to swap dimensions will still receive the vanilla “entered dimension” advancement (for the Nether or the End).
   This is intentional and serves as a small reward for their attempt. And you know who tried by checking their achievements. Don’t worry, they’ll get teleported back safely!
4. Immersive Feedback:
   On teleport back, players see a short action bar message, hear a subtle sound cue and get a slowness effect applied, making the experience clear and responsive without being intrusive.
5. Flexible and Compatible:
   Works as either a global mod or a world-specific data pack, fully compatible with both vanilla and modded setups right out of the box.
6. Server-Ready:
   Built to be reliable, grief-resistant, and completely passive, with no extra overhead through tick-based checks. Perfect for public or semi-public multiplayer servers.
7. Dynamic Configuration:
   Can be adjusted in real time through the in-game config panel, no reloads or restarts required.

TL;DR: A stable and lightweight way to stop unwanted dimension travel, made to just work.

Installation

After adding the data pack/mod to your world or server, you should be able to open the about panel, which is fully controllable with the mouse:

/function disable_dimensions:about

Configuration

You can configure everything through the config panel, which also fully controllable with the mouse. You may toggle the status for each dimension and edit the messages shown to players on return; just be sure to use valid minecraft text component colors. Furthermore, you must also set the World Spawn at least once from this panel. Make sure you’re standing at the desired spawn location when doing so:

/function disable_dimensions:config

Server Only

The config panel will only be usable when you're physically logged in to the server and have op.

To configure the data pack/mod, you can use the config toggles which get called by the config panel directly inside the server terminal as follows:

• The Nether:
  • Enable: function disable_dimensions:config/nether/enable
  • Disable: function disable_dimensions:config/nether/disable
  • Edit Message: function disable_dimensions:config/nether/message {color:"",text:""}
• The End:
  • Enable: function disable_dimensions:config/end/enable
  • Disable: function disable_dimensions:config/end/disable
  • Edit Message: function disable_dimensions:config/end/message {color:"",text:""}
• World Spawn:
  • Set: Not possible due to requiring physical presence at the desired location

Edge Cases

This data pack/mod is intentionally event-driven, with a few rare transitions requiring manual cleanup:

1. Respawn in disabled dimension:
   If a respawn point via a respawn anchor or the spawnpoint command is set inside a dimension that later gets disabled, the player will continue to respawn there until the respawn point is cleared or reset.
2. Already inside on disable:
   Players who are already in The Nether or The End when it gets disabled will remain there until they change dimensions. Teleport them out if needed.
