About the Hyperbox mod

The Hyperbox block acts as a portal to another dimension. Each hyperbox has its own dimension stored within; should the block be mined and placed somewhere else, the dimension will remain linked to that block.

Activating the block sends the player inside this dimension; within the block's dimension are apertures on the walls, which can be activated to return to the overworld.

The apertures transmit redstone power and forge capabilities (such as items being inserted or extracted from hoppers) between the inside and the outside faces of the box, allowing large machines to be constructed in tiny spaces.

The hyperbox is intended to be compatible with anything from other mods that uses standard redstone power or forge's capability system.

Things to be wary about when using this mod:

  • The hyperbox world's chunk is a single chunk at chunk position 0,0. The size of the space useable by the player is 13x13x13, excluding the walls.
  • World borders are not currently supported, as worldborders currently occupy the same size and positions in all dimensions simultaneously. Creating a world border far from the 0,0 chunk may make hyperboxes unuseable until the world border is removed.
  • The single chunk within the hyperbox dimension will remain loaded while the chunk containing the hyperbox block is loaded. This can be disabled via the common config.
  • Hyperbox worlds will be unloaded and stop ticking if their parent block is removed; the world will be loaded again when the block is placed again.
  • To reduce the file size of hyperbox worlds, only the single primary chunk of hyperbox worlds is saved to disk.
  • The default recipes are viewable in the "Images" link at the top of this page.
  • If a copy of an existing hyperbox is made (such as by using the creative mode ctrl-pickblock to copy block entity data into a blockitem), using this hyperbox blockitem will move the original hyperbox to the new location rather than place a new one; this prevents two hyperbox blocks from being linked to the same dimension.

As of 1.20.1-4.0.0.0, Hyperbox bundles the Infiniverse mod via Forge Jar-In-Jar, so it is no longer required to download Infiniverse separately.

Legacy Information:

  • The 1.18.x and 1.19.x versions of Hyperbox require the Infiniverse mod: https://www.curseforge.com/minecraft/mc-mods/infiniverse
  • Prior to 1.20.1, the hyperbox chunk is located at chunk 16,16 instead of 0,0

How to install Hyperbox

With Millida Launcher

  1. Install Millida Launcher

    The launcher is free: download it at millida.net/launcher and sign in with any nickname.

  2. Click “Install” on this page

    The launcher opens and installs the mod for Minecraft 1.16.4–1.21.1 on Forge or NeoForge automatically.

  3. Launch the game

    A profile with it appears in the launcher: click “Play”.

Manually

  1. Install Forge or NeoForge

    The loader must match the game version of the mod file, for example Minecraft 1.21.1. After installing it, a separate profile appears in your launcher.

  2. Download the file for your version

    In the version list above, pick the file hyperbox-1.21-6.0.0.1.jar (256 KB) for your game version and loader.

  3. Put it in the mods folder

    The folder is inside .minecraft (Windows: %appdata%\.minecraft\mods). If it does not exist, create it.

  4. Launch the loader profile

    Open “Mods” in the main menu: Hyperbox should be in the list.

Minecraft 1.21.1 runs on Java 21: with a different Java version the game may close right after launch.
