Description
Slumber
Sleep with progress. Slumber accelerates the entire server tick while everyone sleeps — not just time-of-day. Blocks, entities, block entities, random ticks, scheduled updates, weather, raids… everything advances across all dimensions during sleep.
Features
- Full world ticking: Runs extra full ticks so blocks, entities, and schedules progress.
- All dimensions: Applies to every loaded dimension (Overworld, Nether, End, modded).
- Server + singleplayer: Works on dedicated servers and integrated singleplayer.
- All-players requirement: Only activates when all non‑spectator players are sleeping.
- No instant skip: Temporarily disables vanilla night‑skip while simulating; restores it after.
- Configurable speed: Controlled by a gamerule for quick per‑world tuning.
Configuration
- Gamerule
slumberTickMultiplier(integer, default20): - Total server tick multiplier while all players sleep. - Example:20→ 1 normal tick + 19 extra ticks per server tick (≈20× speed). - Minimum effective value is1(no acceleration).
Commands
- Set multiplier:
/gamerule slumberTickMultiplier 30 - Read current:
/gamerule slumberTickMultiplier
Requirements
- Minecraft: 1.21.1+
- Loader: NeoForge, Forge, or Fabric (matching your MC version)
Installation
- Client (singleplayer/LAN): Drop the JAR into your
mods/folder. - Server: Drop the JAR into the server’s
mods/folder. All connected clients only need to join a modded server; this mod runs server‑side and does not add items/blocks.
Performance Notes
- Multiplier cost: The higher the
slumberTickMultiplier, the more work per real‑time second. Large multipliers with many loaded chunks can impact MSPT. - Recommendation: Start with
20and adjust. Consider reducing if the server approaches 50+ MSPT during sleep.
Multiplayer Behavior
- Activation rule: Every non‑spectator player in the server must be sleeping. Spectators are ignored for this check.
- Partial sleep: If any non‑spectator is awake, Slumber does nothing and vanilla behavior applies.
Compatibility
- Designed to be non‑invasive: it uses event hooks to run extra world ticks, without coremodding.
- Should be compatible with most mods. Extremely heavy tick‑based mods may amplify the cost of higher multipliers.
FAQ
- Does this change loot or gameplay rules? No. It only changes how many world ticks run while everyone sleeps.
- Does it force morning instantly? No. Vanilla fast‑forward is suppressed during the simulation. Once it’s naturally day (or someone wakes), the original threshold is restored and vanilla proceeds.
- Does it affect only Overworld? No. All loaded dimensions tick equally.
