Lait's Animal Breeding

Quick Overview

Animal breeding and baby growth for Hytale to expand your farm.

Disclaimer: This mod prioritizes making livestock reproduction possible. I recommend keeping animals in a pen and close together for best results. Always make a backup before trying new mods - though this one only spawns entities and doesn't modify save data for now.

What It Does

• Feed two animals to breed them (press F with appropriate food)
• Babies spawn and grow into adults over time
• All creatures in the base game supported
• Fully configurable via commands or JSON
• Add custom animals from other mods

What It Can't Do (Yet)

• Define which foods attract animals (uses base game foods)
• Name animals and persist them through game restarts
• Make animals follow you (taming planned)
• Feed babies to speed up growth (planned)
• Interrupt animals that are fleeing or sleeping (the mod doesn't change animal behavior)

Quick Start: Find two animals → feed each one their favorite food → they breed → baby grows up.

Useful commands: /breed config info Cow (check foods) · /breed config preset apply zoo (enable all real animals)

What's New in v1.3.0

Deprecated Commands

The following legacy commands still work but show deprecation warnings. Use the unified /breed command instead:

• /laitsbreeding → /breed help
• /breedstatus → /breed status
• /breedconfig → /breed config

Fixed

• Various performance improvements
• Various bug fixes including handling multiple worlds, potential memory leaks, potential server crashes
• Horse feeding and mounting should now work (might still need to hit them once like in the base game)
• Various bugs caused by changing the model of the player or spawning a model

New Features Preview (some features might not work)

Animal Taming System

• Name Tags - You can now craft name tags at the farming bench and tame an animal
• Random cute names - Animals get random names like Fluffy, Spot, Buddy, Luna, etc.
• Ownership system - Tamed animals belong to the player who tamed them

Entity Persistence

• Persistent taming data - Tamed animals are saved to tamed_animals.json and survive server restarts
• Respawn system - Tamed animals that despawn will respawn at their last position when a player approaches (64 block radius)
• State preservation - Growth stage, breeding cooldowns, and all taming data are preserved across respawns
• Auto-save - Data auto-saves every 5 minutes
• Shutdown save - Data is always saved on server shutdown

Custom Animals (from other mods or future updates)

• Role-first registration - /breed custom add <npcRole> <food> register by NPC role
• Auto model discovery - Plugin validates the role exists, spawns a temp entity, and auto-discovers the model asset ID
• Baby role mapping - New /breed custom setbaby <model> <babyRole> command for dedicated baby NPC spawning
• Scaling fallback - If no baby role defined, babies spawn as scaled-down adults (40% size)
• Custom animal spawn detection - Custom animals are now detected immediately when they spawn (same as built-in animals)

---

Features

• Feed animals to breed - Press F on animals with their favorite food to put them in love mode
• Proximity breeding - Two animals in love will automatically breed if close enough
• Baby animals - Breeding produces baby animals that grow into adults over time
• Wild baby growth - Wild baby animals found in the world also grow into adults
• Breeding cooldown - Parents need time to rest before breeding again
• All creatures in the base game - All livestock in the base presets, as well as wild animals and all other creatures in the base game
• Any custom creature from mods - You can add any creature you added from any other mod (and if there is a baby version of the creature you can also register it)
• Multiple breeding foods - Each animal can accept multiple food items
• Preset system - Quick configuration with built-in presets
• Fully configurable - Customize everything via JSON config or in-game commands

---

Installation

• Place the JAR file in your server's mods folder
• Restart the server
• (Optional) Configure via /breedconfig commands or edit the JSON file
• Feed animals to start breeding!

---

How It Works

• Find two animals of the same type
• Feed each one their favorite food (use /breedconfig info <animal> to check)
• Both animals enter "love mode"
• If close enough, they breed and a baby spawns
• The baby grows into an adult based on the configured growth time

---

Supported Animals

Livestock (Enabled by Default)

Wild Animals (Disabled by Default)

Can be enabled via config or the zoo preset. These spawn as small adults and grow to full size.

---

Presets

Presets are editable JSON files stored in %AppData%/Roaming/Hytale/UserData/Saves/{YourSaveName}/mods/presets/.

default_extended (NEW DEFAULT) - Best of both worlds. Default timings (30 min growth, 5 min cooldown) with multiple food options from lait_curated. Recommended for most players.

default - Streamlined experience with original game values. Single food per animal, 30 min growth, 5 min cooldown. Only livestock enabled.

lait_curated - Organic, natural experience. Multiple foods per animal, logical growth times (chickens 10 min, horses 30 min), balanced cooldowns. Rabbits breed fast (1 min cooldown), large animals need more rest.

zoo - All real-world animals enabled. Includes livestock, mammals, critters, birds, and reptiles. Excludes mythic creatures. Uses lait_curated values.

all - EVERYTHING enabled. All 119 animals across all 10 categories including mythic creatures, vermin, aquatic, and boss dragons. Uses lait_curated values. For the ultimate breeding experience.

Preset Commands

/breedconfig preset list              Show available presets
/breedconfig preset apply <name>      Apply a preset
/breedconfig preset save <name>       Save current config as preset ⚠️ _This will override the previous preset values if the name was already in use and they can't be recovered_
/breedconfig preset restore <name>    Reset built-in preset to defaults

Note: Built-in presets (default, default_extended, lait_curated, zoo, all) are automatically updated with new animals on startup. Use restore to reset a preset to factory defaults if you've modified it.

Creating Custom Presets

If the game tells you you don't have the permissions to use this command, run /op self first

To apply a preset to your world:
Copy an existing preset in mods/presets/, rename it, edit the values, then apply with /breedconfig preset apply my_preset

To create a new preset from the current world config
⚠️ This will override the previous preset values if the name was already in use and they can't be recovered
Configure animals with /breedconfig commands, then run /breedconfig preset save my_preset

---

Custom Animals (Other Mods)

Add creatures from other mods to the breeding system. Simply provide the NPC role name and the plugin will auto-discover the model.

/breed custom add <npcRole> <food> [food2] [food3]   Add by NPC role (auto-discovers model)
/breed custom setbaby <model> <babyRole>             Set baby NPC role for dedicated baby spawning
/breed custom remove <model>                         Remove a custom animal
/breed custom list                                   List all custom animals
/breed custom info <model>                           Show custom animal details
/breed custom enable <model>                         Enable a custom animal
/breed custom disable <model>                        Disable a custom animal
/breed custom addfood <model> <food>                 Add a breeding food
/breed custom removefood <model> <food>              Remove a breeding food
/breed custom scan                                   Scan world for creatures

Example: To add a creature with NPC role "VgSlime_Npc_Guumi_Green":

/breed custom add VgSlime_Npc_Guumi_Green apple

The plugin validates the NPC role exists, spawns a temp entity to discover the model, and registers both for detection and spawning.

Baby spawning: If you know the baby NPC role, set it with /breed custom setbaby. Otherwise, babies spawn as scaled-down adults (40% size).

Custom animals are automatically detected when they spawn and saved to config.

Legacy Commands (Deprecated)

The following commands still work but show deprecation warnings:

• /laitsbreeding → /breed
• /breedstatus → /breed status
• /breedgrowth → /breed growth
• /breedconfig → /breed config

Configuration

Config file: mods/laits-breeding-config.json

{
  "activePreset": "default_extended",
  "defaults": {
    "growthTimeMinutes": 30.0,
    "breedCooldownMinutes": 5.0,
    "growthEnabled": true
  },
  "animals": {
    "COW": {
      "enabled": true,
      "breedingFoods": ["Plant_Crop_Wheat_Item", "Plant_Crop_Cauliflower_Item"],

      "breedCooldownMinutes": 5.0
    }
  }
}

---

Roadmap

Done: Configurable timing, multiple breeding foods, external preset files, all creatures breeding, heart particles

Planned:

• Taming to make domesticated animals follow you
• Feed babies to make them grow faster
• Advanced config (custom scales per growth stage, baby models/NPCs, offsprings count)
• Animal wellness (pet your animals, build trust, mood affects breeding)
• Genetics system (babies inherit traits and appearance from parents)
• Cross-compatibility testing with other mods

---

Known Issues

• Animations don't interrupt - Feeding while an animal is fleeing or sleeping won't interrupt them
• Growth time setting - May not work reliably in all cases (investigating)
• Wild baby animals - May sometimes not grow into adults
• Single world only - Only works with the default world (multi-world not supported)
