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

[SURVIVAL PRESSURE] L7, L10, L94 and L1099 force survival mode; the rest are adventure. Soak in the pool for twenty seconds and you go deeper. Drown in L7 right after drinking almond water, and you end up somewhere you do not want to be.

[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.

▍NOTES

A personal project, built from scratch. ~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：静止
════════════════════════════

把「后室」做进 Minecraft 的维度模组。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

【生存压力】L7、L10、L94、L1099 强制生存模式，其余为冒险模式。在池子里泡满 20 秒会把你带下去；在 L7 憋气憋到淹死、而你又刚喝过杏仁水，你会去一个不想去的地方。

【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。

▍版本支持

  Fabric   Minecraft 1.20.1   已发布
  Forge    Minecraft 1.20.1   已发布
  更高版本  敬请期待

后续会持续适配更多 Minecraft 版本与加载器，关注项目即可收到通知。

▍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，从零手写，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
