🛠️ SmpMechanics
The ultimate utility solution for your Survival Multiplayer server!
SmpMechanics is an all-in-one plugin designed to enhance the SMP experience without breaking the vanilla feel. It combines essential administrative tools, social interactions, and immersive survival mechanics into a single, highly optimized package. From custom day/night cycles to interactive furniture and smart sleep systems—it’s all here!
✨ Key Features
- 🌙 Advanced Sleep System: No more skipping the night instantly! The "Time Warp" mechanic smoothly accelerates time when players sleep.
- Buffs: Players sleeping in beds receive potion rewards.
- Debuffs: Players wandering around at night receive penalties.
- Neutral: Players sitting on chairs/stairs are safe—they skip the night but get no buffs or debuffs.
- ⏳ Custom Day/Night Cycle: Take control of time! Set the day or night duration independent of vanilla game rules.
- 🪑 Social Interactions: Right-click any Stair or Slab to sit down instantly. Toggle whether others can sit on you with
/sittoggle. - 🔥 Cozy Campfires: Relaxing by the fire pays off. Players standing near a lit Campfire will passively regenerate health over time.
- ⚔️ Smart Mob Clear: The unique
/kill monsterscommand removes hostile mobs to reduce lag but protects named entities, pets, and mobs inside boats or minecarts. - 🛡️ Inspector & Logging: Built-in SQLite logger tracks block placement, breaking, and chest interactions. Use the Inspector Tool to check history.
- 🛠️ Admin & Vital Tools: Includes Gamemode switchers (
/gm), Heal/Feed (/heal,/feed), Inventory editing (/eqf), and Flight (/fly). - 🌍 Multi-Language: Full support for English and Polish (switchable via command).
⚙️ Configuration & Modules

- Modules: Toggle
