PecoraGenesis

## PecoraGenesis **PecoraGenesis** is a Minecraft plugin that introduces a **genetics system and livestock management mechanics**. Livestock such as **Cows, Sheep, Pigs, and Rabbits** are assigned genes, and breeding them creates **genetic combinations and mutations**, resulting in varied traits. Wild animals are treated as having the base gene **AA**. Through repeated breeding, genes evolve and affect: - Meat drop amount - Hunger restoration - Twin breeding efficiency - Status effects Additionally, meat obtained from domesticated animals has **special effects**, which can be further enhanced by cooking it over a **campfire**. --- ## Overview Each livestock entity has its own **genetic data**, which is stored in a database file. This allows **persistent tracking of individual genes and traits**. The genetics system includes the following probability factors: - `inherit_chance` (inheritance rate) - `dominance_chance` (dominance rate) These mechanics create breeding results similar to real-world genetics. --- ## Supported Animals The following livestock are affected by the genetics system: - Cow - Sheep - Pig - Rabbit --- ## Cooked Meat Effects Eating cooked meat grants effects depending on the animal and gene level. ### Status Effects | Animal | Gene Level | Effect | Level | Duration | |--------|------------|--------|-------|----------| | Cow | 1 | Strength | I | 10–20s | | | 2 | Strength | I | 40–50s | | | 3 | Strength | II | 5–10s | | Pig | 1 | Haste | I | 30–40s | | | 2 | Haste | I | 60–70s | | | 3 | Haste | II | 20–30s | | Rabbit | 1 | Jump Boost | I | 20–30s | | | 2 | Jump Boost + Slow Falling | I | 40–50s | | | 3 | Jump Boost | II | 20–30s | | | 3 | Slow Falling | I | 20–30s | | Sheep | 1 | Speed | I | 20–30s | | | 2 | Speed | I | 50–60s | | | 3 | Speed | II | 10–20s | --- ### Hunger & Saturation | Animal | Food Level | Hunger | Saturation | Chance | |--------|-----------|--------|------------|--------| | Cow | 0 | 8 | 12.8 | None | | | 1 | 9 | +1 | 40% | | | 2 | 10 | +2 | 30% | | Pig | 0 | 8 | 12.8 | None | | | 1 | 9 | +1 | 40% | | | 2 | 10 | +2 | 30% | | Rabbit | 0 | 5 | 6 | None | | | 1 | 6 | +1 | 40% | | | 2 | 7 | +2 | 30% | | Sheep | 0 | 6 | 9.6 | None | | | 1 | 7 | +1 | 40% | | | 2 | 8 | +2 | 30% | *Note: 2 hunger points = 1 hunger bar icon.* --- ## Checking Genes Right-click a livestock animal with a **Stone Hoe** to view its genes. --- ## Breeding System When breeding livestock, genes are determined with the following probabilities: | Type | Chance | |------|--------| | General inheritance (AG, etc.) | 75% | | Mutation (AA, AG, GG, etc.) | 20% | | Dominant mutation (TG, AC, etc.) | 5% | Mutation order: **A → T → G → C → A ...** --- ## Gene Traits Each gene combination provides different bonuses: | Gene | Drop | Food | Breed | Status | |------|------|------|-------|--------| | AA | 0 | 0 | 0 | 0 | | TA | 0 | 1 | 1 | 0 | | AT | 0 | 1 | 2 | 0 | | TT | 0 | 2 | 0 | 0 | | GA | 0 | 0 | 1 | 0 | | AG | 1 | 0 | 2 | 0 | | GG | 3 | 0 | 0 | 0 | | CA | 0 | 0 | 1 | 1 | | GT | 2 | 1 | 0 | 0 | | TG | 1 | 2 | 0 | 0 | | AC | 0 | 0 | 2 | 1 | | TC | 0 | 2 | 0 | 1 | | CT | 0 | 1 | 0 | 2 | | CG | 1 | 0 | 0 | 2 | | CC | 0 | 0 | 0 | 3 | | GC | 2 | 0 | 0 | 1 | --- ## Trait Explanation | Trait | Description | |------|------------| | Drop | Meat drop amount | | Food | Hunger & saturation restoration | | Breed | Twin breeding chance | | Status | Strength of status effects | ### Additional Notes - Twin breeding chance: - 0 = None - 1 = 25% - 2 = 50% - Meat drop multiplier: - 0 = Vanilla - 1 = 1.2× - 2 = 1.5× - 3 = 2.0× - Milk cooldown chance: Determines the probability of a **5-minute cooldown** when milking cows/goats. --- ## Compatibility - Paper - Purpur - Spigot - Bukkit ### Supported Minecraft Versions - Minecraft **1.21.x** ### Requirements - Java **21+** --- ## Installation 1.
