☽ Overnight

Make your nights count.
A Minecraft Fabric mod and Datapack that accelerates crop, tree, and animal growth while players sleep.

--- ## 📖 Description **Overnight** makes sleeping in Minecraft actually meaningful. Instead of just skipping the night, your crops, saplings, and baby animals continue growing while you rest — as if time truly passed. ### How It Works - **Plants & Trees**: When a player sleeps, the `randomTickSpeed` is temporarily multiplied by your configured rate (default **100x**), causing all crops, saplings, sugar cane, cactus, bamboo, nether wart, and other vegetation to grow rapidly during the brief sleep window. - **Animals**: Baby animals have their `Age` tag accelerated each tick during sleep, making them grow toward adulthood faster (default **100x**, but **disabled by default**). - **Fire Safety**: `doFireTick` is automatically disabled during sleep acceleration and restored when players wake up, preventing unwanted fire spread. - **Clean Recovery**: If the server reloads mid-sleep (`/reload`), original gamerules are automatically restored. ### What's Affected by Plant Growth? All vegetation that uses random ticks, including: | Category | Examples | |---|---| | **Crops** | Wheat, Carrots, Potatoes, Beetroots, Melon/Pumpkin Stems | | **Trees** | All Sapling types (Oak, Birch, Spruce, Jungle, Acacia, Dark Oak, Cherry, Mangrove, Pale Oak) | | **Tall Plants** | Sugar Cane, Cactus, Bamboo, Kelp, Vines, Dripleaf | | **Other** | Nether Wart, Cocoa Beans, Sweet Berries, Chorus Plants, Mushrooms | ### What's Affected by Animal Growth? All breedable baby animals in the `#overnight:growable_animals` tag: > Cow, Mooshroom, Sheep, Pig, Chicken, Horse, Donkey, Mule, Llama, Rabbit, Fox, Turtle, Panda, Polar Bear, Wolf, Cat, Ocelot, Goat, Axolotl, Camel, Sniffer, Bee, Hoglin, Strider, Villager You can customize this list by creating your own `data/overnight/tags/entity_types/growable_animals.json` override. --- ## 📦 Installation ### Fabric Mod 1. Ensure you have the **Fabric Loader** and **Fabric API** installed for Minecraft `1.21.4` (snapshot `26.1.2` equivalent). 2. Download the `.jar` file from Modrinth. 3. Place the file into your `.minecraft/mods/` directory (for singleplayer) or `/mods/` (for servers). 4. Launch the game. ### Datapack 1. Download the datapack `.zip` file. 2. **Singleplayer**: Place the `.zip` file into: ``` .minecraft/saves//datapacks/ ``` 3. **Server**: Place the `.zip` file into: ``` /world/datapacks/ ``` 4. Run `/reload` in the console or in-game (or restart the world/server). --- ## ⚙️ Configuration ### Fabric Mod Commands The Fabric mod provides a dedicated `/overnight` command (requires OP/moderator level 2 permission): | Command | Description | |---|---| | `/overnight status` | View the current configuration status and rates | | `/overnight toggle plants` | Toggle plant & tree growth acceleration | | `/overnight toggle mobs` | Toggle animal growth acceleration | | `/overnight rate plants ` | Set plant growth rate multiplier (e.g. `/overnight rate plants 200`) | | `/overnight rate mobs ` | Set animal growth rate multiplier (e.g. `/overnight rate mobs 50`) | ### Datapack Commands The Datapack version uses `/function` commands and features an interactive chat menu: | Command | Description | |---|---| | `/function overnight:config/menu` | Open the interactive config menu | | `/function overnight:config/toggle_plants` | Toggle plant & tree growth acceleration | | `/function overnight:config/toggle_mobs` | Toggle animal growth acceleration | | `/function overnight:config/set_plant_rate {rate:N}` | Set plant growth multiplier (e.g. `{rate:200}`) | | `/function overnight:config/set_mob_rate {rate:N}` | Set animal growth multiplier (e.g. `{rate:50}`) | ### Default Settings | Setting | Default | Description | |---|---|---| | Plants & Trees | **ON** | Accelerate crop/sapling growth during sleep | | Animal Growth | **OFF** | Accelerate baby animal growth during sleep | | Plant Rate | **100x** | Multiplier applied to plant growth / `randomTickSpeed` | | Animal Rate | **100x** | Multiplier applied to baby animal age progression | ### Rate Guide | Rate | Effect | Recommended For | |---|---|---| | **50x** | Moderate growth boost | Survival purists who want a subtle benefit | | **100x** | ~80% of a full night's growth per sleep | **Default — balanced for most players** | | **200x** | Significant acceleration | Players who want noticeable overnight progress | | **500x** | Extreme acceleration | Creative/testing (may cause brief lag) | --- ## 🔧 Technical Details ### Architecture - **Sleep detection**: Polls `SleepTimer` NBT every tick using a single efficient selector - **State machine**: Tracks sleeping transitions (start → tick → stop) with scoreboard flags - **Plant acceleration**: Multiplies `randomTickSpeed` during the ~100-tick sleep window - **Animal acceleration**: Reads/modifies baby `Age` NBT via scoreboard operations each tick during sleep - **Safety**: Saves and restores `randomTickSpeed` and `doFireTick` gamerules, with fallback defaults ### Performance - Tick function is a single `execute store` + 3 conditional checks (negligible overhead) - Mob growth only processes entities matching `#overnight:growable_animals` tag AND `is_baby` predicate - All acceleration only runs during the brief sleep window (~5 seconds in singleplayer) ### Multiplayer - Acceleration activates as soon as **any** player sleeps (regardless of `playersSleepingPercentage`) - Deactivates when the **last** sleeping player wakes up - Works with vanilla sleep percentage rules and one-player-sleep datapacks --- ## 📁 Project Structure ``` Overnight-Datapack/ ├── pack.mcmeta # Pack metadata (format 101) ├── pack.png # Datapack icon ├── LICENSE # CC BY-NC-ND 4.0 ├── README.md └── data/ ├── minecraft/tags/function/ │ ├── load.json # Hook: runs on load/reload │ └── tick.json # Hook: runs every game tick └── overnight/ ├── tags/entity_type/ │ └── growable_animals.json # Baby animal types to accelerate ├── predicate/ │ └── is_baby.json # Efficient baby entity check └── function/ ├── load.mcfunction # Initialize scoreboards & defaults ├── tick.mcfunction # Sleep state detection loop ├── sleep_start.mcfunction # Save gamerules, apply acceleration ├── sleep_tick.mcfunction # Per-tick mob growth dispatch ├── sleep_mob_tick.mcfunction # Baby animal age manipulation ├── sleep_stop.mcfunction # Restore original gamerules ├── apply_plant_speed.mcfunction # Calculate & set tick speed ├── set_tick_speed.mcfunction # Macro: gamerule setter └── config/ ├── menu.mcfunction # Interactive chat config UI ├── toggle_plants.mcfunction # Toggle plant growth ├── toggle_mobs.mcfunction # Toggle animal growth ├── set_plant_rate.mcfunction # Macro: set plant multiplier └── set_mob_rate.mcfunction # Macro: set animal multiplier ``` --- ## 📋 Credits **Created by** [@TomerGamerTV](https://github.com/TomerGamerTV) --- ## 📄 License This project is licensed under the **[Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License](https://creativecommons.org/licenses/by-nc-nd/4.0/)** (CC BY-NC-ND 4.0).
