Breeder's Ledger

"Your animals. Your rules. Your ledger."

Breeder's Ledger is a server-friendly animal ownership mod for NeoForge that brings real livestock management to multiplayer Minecraft. Claim animals, protect them, control who can interact with them, and watch ownership pass down through breeding generations.

FEATURES ARE STILL WIP !

Claiming Animals

Ownership is dead simple. Feed an animal and it's yours.

Player feeds a Sheep with Wheat
> Sheep is now owned by: Steve
> No other player can shear, dye, lead, or breed it (configurable)

The first player to feed an unclaimed animal becomes its owner. Ownership won't be stolen if someone else feeds your animal.

---

Generational Ownership

When your animals breed, their babies inherit ownership automatically. Here's how it resolves under the hood:

if (sameOwner) return ownerA; // both parents are yours, baby is yours
if (differentOwner) return null; // different owners, baby stays neutral
if (breeder != null) return breederAsOwner; // whoever fed them gets the baby

So if both parents belong to you, the baby is yours. If they belong to two different players, the baby stays neutral so there's no ownership conflict.

---

Ownership Protections

Once claimed, your animals are protected from griefing. Server admins can toggle each protection individually so the rules fit the server's vibe:

Protection	Config Key
Other players attacking	allowHurt
Feeding / breeding	allowFeedBreed
Shearing	allowShear
Milking	allowMilk
Putting on a lead	allowLead
Riding / mounting	allowRide
Dyeing (sheep)	allowDye
Name tags	allowNameTag
Armor / harness	allowHarness

Want a server where anyone can milk cows but nobody can steal your horse? Two toggles and you're done.

Animal Behavior Modes

Right-click your own animal with an empty hand to cycle through behavior modes:

NORMAL  >  STAY  >  FOLLOW  >  HERD_BOND  >  NORMAL  > ...

NORMAL is just vanilla behavior. STAY locks the animal in place so it stops wandering off. FOLLOW makes it trail you around using a custom goal. HERD_BOND gets it to stay close to nearby animals of the same type, which is great for keeping a flock together without fences.

FollowMode next = animal.getData(ModAttachments.FollowMode.get()).next();
animal.setData(ModAttachments.FollowMode.get(), next);
player.sendSystemMessage(Component.literal("§e[Breeder's Ledger] §r" + animal.getName().getString() + " is now §e" + next.displayName() + "§r."));

Every mode syncs to all nearby players in real time so everyone sees the same behavior.

HUD Stat Overlay

Hover on any animal and a panel appears in near your crosshair with everything worth knowing at a glance:

(Your) Horse
Speed (horseValue / maxValue)      
Jump (horseValue / maxValue)     
Max HP (horseValue / maxValue)     
Breeding ( isInLove() )
Seen (server age)

(Your) Sheep 
Can shear ( isShearable() )
Breeding ( isInLove() )
Seen (server age)

(Your) Baby Sheep 
Growth (time left)
Seen (server age)

It pulls from several stat modules depending on what kind of animal you're looking at. Speed, jump, and max health show up for rideable animals. Wool and egg timers appear for sheep and chickens. Breeding cooldown and growth progress show for anything breedable. And the owner's name always sits at the top as a header.

The panel itself is pretty customizable too. You can change the color theme, switch to compact mode that shows only values, pick from four HUD positions, scale it up or down, toggle the fade animation (WIP), and even lock it behind a sneak key so it only appears when you're holding Shift.

Server Admin Controls

Server operators get full control over the ownership system and any changes sync out to all connected players the moment they're applied.

PacketDistributor.sendToPlayer(player, OwnershipConfig.INSTANCE.toSyncPayload());
PacketDistributor.sendToAllPlayers(syncPayload); // fires on every config update

Admins can also do a full ownership reset in one action, which wipes every animal's owner, resets their follow mode back to normal, and clears any no-despawn flags. Useful for fresh starts or fixing a messy situation on a community server.

---

No Despawn

Owned animals never despawn while their owner is online. The mod tracks this per-player so your carefully bred horse or your prize sheep stays loaded and alive even if you wander far from the farm.

---

Built for Multiplayer

The whole mod is designed server-first. Ownership data lives in NeoForge Data Attachments so it persists across restarts. Everything syncs on login, on entity spawn, on breeding, and whenever the config changes. Permission checks make sure only OPs can do resets or config edits. And the whole system handles multiple players interacting with the same animals gracefully without race conditions or stale data.

---

Perfect For

• Multiplayer survival servers with shared farms

• Community farming setups where griefers are a real concern

• Roleplay worlds that want actual livestock ownership as part of the lore

• Hardcore servers where losing a prized horse to other players is annoying

• Competitive servers where animal stats actually matter
