Sleep Persist (Players Sleeping %)

Server-side NeoForge mod for Minecraft 1.21.1 that keeps the playersSleepingPercentage gamerule persistent across reboots. Set it once, and it’ll stick even after restarts and auto-apply to all dimensions on startup.

• Persistent sleeping % stored in the world save (default 30%)
• Auto-apply on server startup (first tick)
• All dimensions covered
• Zero client requirement (server-only)

Commands (ops only)

• /sleeppercent get — shows the stored percentage
• /sleeppercent set 0-100 — persists the value and applies immediately
• /sleeppercent apply — re-applies the stored value to all loaded worlds

Compatibility

• Loader: NeoForge (21.1.x)
• Minecraft: 1.21.1
• Java: 21
• Pure server-side; clients don’t need the mod.

2. Start the server (accept EULA if needed).
3. Optional: set your preferred value: /sleeppercent set 50 It’ll persist and survive reboots.

FAQ

Q: Where is the value saved?
A: In your world’s data as sleeppersist.dat (SavedData). Delete it to reset to defaults.

Q: New dimensions added later?
A: They’ll get the current setting when the server next applies it (on restart or /sleeppercent apply).
