Craft a device that opens a door to a private dimension. Yours to expand, power, and protect.

Personal Pocket Dimension adds device-linked private spaces to Vintage Story. Build a stationary Personal Attunement Destination Device (sPADD) and it will instantiate a persistent pocket dimension anchored to that device. Unlock further progression and you can craft a handheld hPADD to carry portable access to your dimension wherever you go.

Special Notice

I hate that I even have to make this abundantly clear, but there has been an accusation thrown around, so let me put this to bed here and now.

• I used AI in a singular project to help flesh out a plan.md file to help me avoid Feature Creep. In my 20+ years of programming, including web design and front end/backend development, its the one thing that has killed more of my projects than anything else.
• No, I do not use AI in any of my coding projects in any way that ever becomes public facing. The code you get from me is authored by my hands alone. I'd rather do it by hand than spend 2-3 hours fixing things I could have done myself in an hour or less.
• That will never change as I have a very strong stance on taking the lazy way out in everything I do.

Special Notes

For Server Admins and Users in Creative

Never middle mouse pickup a Stationary PADD. Stationary PADDs hold the data for the PPD it's attached to so that when in survival you can move it to update the exit location. This has the unintended side effect of creating multiple PADD Key Pendants and invalidation the old exit PADD.

Warnings

While there are people in Pocket Dimensions, do not deactivate either this mod or Manifold as it will cause those people to be stuck there and may cause your save to break. Further reminder, this is an Alpha Build of Personal Pocket Dimension. It's sole purpose is to get tests on a broader range and with more people so that we can fix any underlying bugs I more than likely missed in my singleplayer tests.

How it works

Stationary PADD and your pocket dimension

Craft and place an sPADD to create your Personal Pocket Dimension. The device acts as the root anchor, not just an entrance. Interacting with it opens a short-lived portal that anyone nearby can step through.

When your PPD is first created, it generates a control room and entryway built from indestructible materials. The entryway always returns you to the linked sPADD; anyone inside can leave freely, no key required.

The Key Pendant

When you first activate your sPADD, you receive a linked Key Pendant. Only a player carrying or wearing the matching key can open the portal from outside, authorize hPADD links, and command the PPD control room. The key represents access authority. Give it away and you transfer practical control in-world.

Keys should not be lost on death, making them safe to wear as pendants even in dangerous situations.

Temporal Energy

Your pocket dimension runs on Temporal Energy, stored in the control room. Lighting and room activity are driven by available TE. Feed the Chronofuser in your control room with powdered temporal dust or temporal gears to keep your dimension running.

Chronobasin

The Chronobasin is a top-loading multiblock basin that processes metals for use in PADD construction. Load up to 6 ingots at a time. Each ingot requires 20 brass bits, 1 coke, and 1 temporal dust to produce one Chronobrass ingot, the material gating sPADD crafting.

Construction follows the Bloomery as a template. Craft Raw Temporal Refractory Bricks using the standard Refractory Brick (Tier 1) recipe with two temporal dust added to the bottom two slots, then fire them as normal. The Chronobasin base uses the Bloomery base recipe inverted, and the chimney mirrors the Bloomery chimney, both substituting Temporal Refractory Brick for Fire Clay Brick.

Expanding your dimension

From inside your pocket dimension, the PPD-side sPADD opens a visual builder interface. A top-down grid shows your current layout, occupied cells, open sockets, and connection states. Select a socket, choose a room type or hallway, set your rotation, and confirm. The server validates your key access, available TE, and adjacency before committing. Rooms can stack vertically where both adjacent schematics support it.

Handheld PADD

Later progression unlocks the hPADD. Link it to a PPD by shift-interacting with the corresponding sPADD while wearing the matching key. The hPADD lets you open a portal from anywhere in the world, cycling between any PPDs you've been authorized to access.

Crafting progression

The core of every PADD device is the Manifold Core, which requires components from Jonas technology. The primary route uses an Eidolon elucidatory vessel obtained through Resonance Archives progression. A server-friendly alternate route lets you craft an incomplete vessel from Jonas parts, but this fallback deliberately cannot be converted into the base-game vessel, protecting story progression.

The sPADD itself is gated behind Chronobrass, produced in the Chronobasin, preventing shortcuts through salvaged cupronickel parts.

Planned future content

• Temporal Crystals: a higher-density fuel refined from rough-cut diamonds and liquid temporal coating, coming soon
• More room types: storage, workshops, farming, utility, living quarters
• hPADD upgrade for storing static world locations
• Expanded access and permission roles for shared dimensions
• Portal opening/closing sounds and visual polish

Current status early alpha

This mod is in active development. Core sPADD behaviour, PPD generation, portal mechanics, the Key Pendant, Chronofuser, Chronobasin, and the visual PPD builder are implemented. Many planned features are still in progress. Expect rough edges and remember, feedback and bug reports are very welcome.
