Mini Tardis: BOTI

by enjarai · on Modrinth

Which Minecraft do you have?

Every version of the game needs its own build. Pick yours, then download — the wrong build installs fine and then does nothing in the game. This mod is built for Fabric only.

Minecraft 1.21–1.21.1Newest
Minecraft 1.20.1

⬇ Download for 1.21–1.21.1 ⬇ Download for 1.20.1

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Overview

This is a highly work in progress compatibility layer between Mini Tardis and Immersive Portals, using the latter to create a "Bigger on the Inside" or BOTI effect for the TARDIS. It additionally fixes a hard incompatibility that Mini Tardis has with Immersive Portals when used alone together.

Important

This mod completely and utterly smashes and destroys the Polymer-based server-side functionality of Mini Tardis I worked so hard to create, though it does so in a moderately controlled manner. This is to say, it will only work when used on both server and client.

Disclaimer

Despite being fully functional in testing, this mod is marked alpha for a reason. Expect bugs, and please report any you find on the issue tracker or my Discord.
