ATTENTION: Duplication bug (maybe fixed in 2.1.8)

There has been for a long time (since v2.0 or maybe even earlier), a strange duplication bug that has been almost impossible to reproduce in my development environment. I hope this has been fixed in V2.1.8, but the lack of a consistent set of steps to reproduce means I can't properly verify it.

NEW: Tutorial/Manual book in v2.0

Starting with v2.0, Ender-Rift supports an ingame manual, through the use of the Guidebook mod.  If this mod is installed, the recipe for the book will be available.


What happens when you trap an in-flight ender pearl in a redstone field, and then send a redstone flux to it? Someone found the answer during what seemed like a catastrophic failure of an experiment.

The ender pearl shatters and in its place a rift is opened into the between-space used by the endermen to teleport. Harnessing this rift, you are able to keep an unlimited amount of items in a seemingly tiny space.

WARNING: Although the ender field is self-sustaining, if the ender field is destroyed, the rift closes, and if all the shared rifts close, it has been proven impossible to reach the same between-space ever again!*


* Except by the all-powerful gods of that universe.


Ender-Rift provides a virtually unlimited storage solution. This storage has no default way of accessing it (no GUI), and instead relies on external blocks providing inventory access. For this purpose, the mod provides an inventory network system, with a limited but automatable interface, and a searchable browser block that can't be automated. This network requires its own power separate from the energy needed to maintain the rift.

Feature List

  • The Ender-Rift: A bottomless storage system that uses energy to maintain a pocket of storage space in the between-space created by an ender pearl's teleport effect.
    • Assemble the multiblock structure as explained in the Wiki pages, and then rightclick the rift core block with a rift orb. If the orb was bound to an existing rift, it will give access to that rift, otherwise, a new rift will be created.
    • Right-click an existing assembled rift with an unbound rift orb to bind the orb to the existing rift. This allows ender-chest-like access to the same items from multiple locations.
      • Note that each rift needs to be powered independently in order to allow access from that structure.
  • The Rudimentary Generator: Takes a while to heat up to maximum efficiency, and it has no control circuit, so it will keep generating energy even if the storage buffer fills up. A temporary solution for when no other power sources are available.
  • The Rift Browser: allows accessing the inventory of a Rift, and also other inventories such as chests.
    • With searchbox: You can now filter the items by any information shown in the tooltip.
  • Rift Crafting Browser: an upgraded browser with integrated crafting table. Note however: it does not auto-refill itself from the inventories, it's just a plain old crafting grid.
  • The Rift Interface: allows accessing the rift's contents in an automated way, either by exporting a predefined kind of item, or by inserting items into it.
  • Rift Proxies: extend the range of Rift Browsers and Interfaces, allowing connections with more than one target, and to targets that are further away. Note however that the scanning range is limited to 32 blocks.
  • Rift Driver: provides power to the inventory networks, allowing one or more interfaces to access the contents of the attached inventories.
  • Powered by the Forge Energy capability (READ ME).

    • The Tesla API is also optionally supported.

    • The old RF API however, is not, and will never be.

Future Plans

  • Fluid rifts. No idea how those would work.
    • Maybe each independent rift could act as a tank with a single fluid?
    • Crazy idea: Configurable contents?
      • An items module would add storage for N item stacks, and have a passive cost.
      • A fluid module would add storage for N buckets of one fluid, and have a passive cost.
      • Other modules?
    • Alternative idea: store fluids as non-stackable "items",  with up to 1B capacity, alongside the normal items?
      • Downside: requires a special "fluid item", and it would be awkward to manage the inventory.

If you need to recover a rift

It is possible to lose the rift by destroying the orb item by mistake. If that happened to you, it is still possible to recover the rift by using cheat/op commands to spawn a rift item with the right ID, like so:

/give <playername> enderrift:itemEnderRift 1 0 {RiftId:<number>}

The rifts are numbered starting at 0, and always growing, so if a new rift would have id 5, that means the previous one was id 4, and so on.

Note that although it is possible to spawn rifts with numbers larger than the last created, it is strongly recommended against, because those numbers will eventually be repeated during normal rift generation.

Can I use this in <X>?

Yes. Unless <X>'s license is incompatible with this mod's, which is unlikely.
