# OneDimension

The Nether, the Overworld and the End — stacked into a single dimension.

OneDimension adds one new world type. Select "One Dimension" when creating a world and you get all three vanilla realms fused into one literal dimension, stacked by height. No portals to separate dimensions — dig down far enough and you punch through into the Nether; build up high enough and you reach the End. It's all one continuous world.

## How it's stacked

From bottom to top, in a single 1536-block-tall dimension:

| Band | Where | What | |---|---|---| | The End | near the world ceiling | Floating islands, the dragon fight, End cities | | The Void Gate | high above the surface | A dark, damaging stretch you must cross to reach the End (lifted once the dragon falls) | | Overworld | normal Y (−64…319) | Your familiar world — unchanged coordinates | | Obsidian floor | beneath the surface | The one mineable barrier; the Nether ceiling sits flush right under it | | Nether | far below | Native Nether terrain, biomes, fortresses, fast-flowing lava — on a solid bedrock world floor |

The Overworld keeps its exact vanilla coordinates, so everything you know still works at the heights you expect.

## What you get

• A real stacked world — genuine Nether, Overworld and End terrain, each
• generated by vanilla worldgen, in one dimension.
• Per-band biomes, mobs, features and structures — End cities and Nether
• fortresses generate in their bands and `/locate` finds them. Nether basalt/fire/
• fungus and End chorus all grow where they should.
• The full dragon fight — the bedrock fountain and all ten spikes build high in
• the End band, the dragon spawns, fights and dies as normal, and the end credits roll
• when you enter the exit portal.
• In-world portals — End and Nether portals warp you within the stacked
• dimension (up to the End platform, down to the Nether) instead of to a separate one.
• The Void Gate — an escalating-damage band (with a hard death zone) between the
• surface and the End, so reaching the top is a real journey — lifted for good once you
• defeat the dragon, opening a walk-up route to the End.
• Real Nether lava — flows fast and far in the Nether band, just like a normal
• Nether; Overworld lava stays slow.
• Vanilla-accurate dimension quirks — beds explode in the Nether and End bands (but
• work in the Overworld), and the Overworld band has a normal day/night cycle and working
• clocks.
• A dig path to the Nether — break through the mineable obsidian floor to descend.
• Correct atmospherics per band — Overworld lighting, sky, fog and rain; the End has
• its proper dark sky and fog with a full view distance; an ominous near-black fog in the
• Void Gate between; no clouds up top; a brighter Nether. The dragon only shows once you're
• up in the void zone or the End.

## Admin controls

OPs can tune the Void Gate's hazards on the fly:

• `/onedimension menu` — a chest-menu panel (works on a vanilla client) with toggles
• for the void damage and the instant-death band.
• `/onedimension voidgate damage|deathband ` — toggle each hazard
• independently from the command line. Both are also editable in the config file.

## Known issues

• It's a tall dimension, so it's heavier than a normal world. Allocating more RAM
• (4 GB+) is recommended, especially at high render distances.

## Starting a server Make sure to set the level-type to `onedimension:one_dimension` and delete the existing world, start the server and it should generate a one dimension world.
