SlumberSignal

SlumberSignal is a client-side only Fabric mod for Minecraft 26.1.2. It does exactly one thing: it tells you the exact moment the Overworld night becomes dark enough to use a bed, with a deliberately over-animated notification.

you can sleep now.

Features

Intelligent Sleep Detection

The mod detects the exact moment sleeping becomes possible, using the same rule the server uses (BED_RULE environment attribute -> BedRule.canSleep). This means thunderstorms and other weather conditions that block sleeping are properly respected. It only fires while the player is in the Overworld.

Once-Per-Night Notification

It shows the message you can sleep now. exactly once per night. It never spams you. The notifier is automatically re-armed on dimension change, world change, join, and disconnect.

Over-Animated HUD

When the notification fires, it displays a heavily animated, compact HUD panel (no full-screen flash). The animation timeline includes:

• A breathing vignette and two drifting star layers
• Three shockwave rings
• A pulsing bloom
• An elastic sliding plate with scrolling parallax art and a shine sweep
• Four popping corner ornaments
• A bobbing shining wordmark
• A breathing tilting moon
• A hopping squash-and-stretch bed with rising Zzz
• Ten orbiting sparkle sprites
• Per-letter typed, waving, and color-shifting text
• A countdown bar showing how long the toast will stay

Zero Configuration

No config file is ever created. All state is kept entirely in memory.

Version Scheme

SlumberSignal follows Semantic Versioning + build metadata in the format MAJOR.MINOR.PATCH+mc<minecraft_version>. The version number is always maintained in gradle.properties (mod_version), and fabric.mod.json reads it automatically via ${version} — it is never hardcoded.

Only one position is incremented per release, matching the biggest change in that release. If a release contains both bug fixes and new features, only MINOR is incremented — a new feature always outranks a bug fix.

Technical Details

This mod — and this description — was made entirely with AI assistance, in Thailand. Everything you see here is AI-generated. Is the mod good? Yes, I think so. But if you have a problem with people using AI to make mods, that is your problem, not mine. Don’t believe this summary was written by AI? That is also your problem.

Future Plans

I might add features, fixes, or other things in the future — things that neither you nor I know about yet. Confused why I am telling you this? Because I might think of a feature at any moment. That is all.

This mod does not use any external libraries. The only dependency is Fabric API.
