Backrooms: Stillness

Backrooms: Stillness
════════════════════════════

A dimensions mod that brings The Backrooms into Minecraft. The moment you get stuck inside a block in the Overworld, you may clip into the Backrooms.

▍WHAT IT IS

13 standalone dimensions, each with its own geometry generator — not the same maze recolored.

L0 The Backrooms L37 Poolrooms
L1 Parking Garage L94 Motion
L2 Pipe Tunnels L1099 The Megalopolis
L3 Power Station L150 Garden Corridors
L4 Abandoned Office L188 Court of Windows
L7 Thalassophobia The Hub (where all paths meet)
L10 Wheat Fields

Levels are not connected through menus — you walk there. Dark walls, cracked walls, pipe mouths, holes in alleys, freight elevators, elevator pads, flooding, holding your breath, glowing blocks: every one of them is a real object hidden in places you have walked past a hundred times.

▍FEATURES

[TWO LOCKED SLOTS] A notebook and a flashlight. Always in slots 1 and 2. They survive death, cannot be dropped, and Q will not throw them. Entering the Backrooms wipes whatever you brought from the Overworld.

[A 21-CHAPTER HANDBOOK] A book you can actually read. Every level is documented in standard Backrooms format: survival difficulty, entity count, description, structures, entrances, exits, warnings.

[FIVE ENTITIES] Facelings, Deathmoths, Hounds, Bacteria, Smilers. Density gradients, per-level caps, respawn intervals — and they never spawn right in front of you. Behind walls, out of sight.

[SOUND] Every level's ambience comes from real recordings of similar places (CC0 sources, remixed): fluorescent ballast hum, garage ventilation, dripping pipes, pool reverb, open-field wind. Not synthesized noise.

▍INSTALLATION

Fabric: requires Fabric Loader and Fabric API.
Forge: requires Forge 47.x, no other dependencies.

▍NOTES

A personal project, deepseek harness to write code. ~11,000 lines of Java across 13 level generators.

Generation is deterministic, but existing chunks are not regenerated — after parameter changes, start a new world or travel a few thousand blocks.

Play in a new world. This mod is not about horror

后室：Stillness
════════════════════════════

把「后室」做进 Minecraft 的维度。你在主世界被方块卡住的那一刻，有概率卡入后室。

▍是什么

13 个独立维度，每层都有自己的几何生成算法，不是同一个迷宫换个颜色。

L0 后室 L37 池厅
L1 停车场 L94 动画
L2 管道层 L1099 巨构
L3 发电站 L150 花园长廊
L4 废弃办公室 L188 百窗庭
L7 深海恐惧 枢纽（所有路径交汇的地方）
L10 麦田

层与层之间不是点一下就传送，而是真的走过去。深色墙、裂纹墙、管口、胡同里的坑、货梯、客梯踏板、泡水、憋气、极亮方块——这些物件都藏在你已经路过一百次的地方。

▍特点

【锁死的前两格】一本书、一只手电筒，永远在第 1、2 格，死不掉、丢不掉、Q 键扔不出去。进入后室时，从主世界带来的东西会被清空。

【21 章手册】那本书真能读。每层按后室标准写法记录：生存难度、实体数量、景象、结构、进入、离开、注意。

【五种实体】无面灵、飞蛾、猎犬、细菌、笑魇。有密度梯度、整层上限、刷新间隔，而且不会在你脸上刷——必须在你视野之外、且隔着墙。

【声音】每层环境音都来自录自同类场所的真实录音（CC0 素材二次加工）：荧光灯镇流器嗡鸣、地下车库通风、管道滴水、泳池回响、田野的风。不是合成白噪声。

▍安装

Fabric 版：需要 Fabric Loader 与 Fabric API。
Forge 版：需要 Forge 47.x，无任何前置。

▍说明

单人开发，deepseek harness写代码，13 个层级生成器约 11,000 行 Java。

生成是确定性的，但已生成的区块不会重算——改了参数后要么开新存档，要么走远几千格。

MIT 许可，第三方素材署名见 jar 内 THIRD_PARTY_NOTICES.md。

建议开新存档。这个模组的目标不是恐怖，是迷失感
