Livestock Genetics & Physical Size Scaling
| Attribute | Value |
|---|---|
| Entity Scale Attribute | minecraft:scale |
| Normal Scale Range | $0.75x \le \text{scale} \le 1.30x$ |
| Absolute Minimum Scale Floor | $0.25x$ |
| Item Drop Scaling | Proportional to scale multiplier ($\text{yield} \propto \text{scale}$) |
| Spacious Pasture Recovery Boost | $+15%\text{ per generation}$ (up to $1.30x$) |
🧬 Physical Size Attribute (minecraft:scale)
Natural Reproduction registers 3 data-driven genetic traits across all 27 animal species using DasikAnimalGeneticsAPI:
| Trait Key | Target Entity Attribute | Attribute Operation | Base Range | Dynamic Bounds |
|---|---|---|---|---|
scale | minecraft:scale | ADD_VALUE | $0.50x \le \text{scale} \le 1.30x$ | Configured live via MIN_SCALE ($50%$) & MAX_SCALE ($130%$) GameRules. |
max_health | minecraft:generic.max_health | ADD_VALUE | $+2.0\text{ HP Base}$ | Bounds: $-4.0\text{ HP}$ to $+12.0\text{ HP}$ bonus max health. |
movement_speed | minecraft:generic.movement_speed | ADD_MULTIPLIED_BASE | $+5%\text{ Speed Base}$ | Bounds: $-4%$ to $+8%$ bonus movement speed. |
Physical Scale Inheritance Math
$$\text{baseScale} = \frac{\text{parent}_1.\text{scale} + \text{parent}_2.\text{scale}{2.0}$$
- In native climate biomes, offspring receive a $+15%$ genetics quality boost: $$\text{boostedScale} = \text{baseScale} \times 1.15$$
🍖 Dynamic Scale-Based Item Drop Yields
When animals are slain or harvested: $$\text{Drop Yield} = \lfloor \text{Vanilla Drop Count} \times \text{scale} \rfloor$$
- Giant Mobs ($\text{scale} = 1.30x$): Yield $+30%$ bonus meat, leather, and wool.
- Stunted Runts ($\text{scale} = 0.25x$): Yield minimal drop counts.
🏚️ Cramped Space Penalty vs. 🌾 Spacious Size Recovery
The crowding evaluation runs both for structural confinement (pits, 2x2 pens) AND large open pastures (e.g. 100x100) whenever local mob crowding is high:
$$\text{isOvercrowded} = \text{isConfinedPen} \lor (\text{extraLocalCount} \ge 3)$$
Continuous Density Penalty Formula
When $\text{isOvercrowded}$ is true, the penalty multiplier is calculated continuously: $$\text{penaltyMultiplier} = \max(0.95 - (\text{extraLocalCount} \times 0.05), 0.40)$$
$$\text{newScale} = \text{clamp}(\text{currentScale} \times \text{penaltyMultiplier}, 0.25, 2.0)$$
| Crowding Density | Penalty Multiplier | Generation Scale Reduction |
|---|---|---|
| 1 Extra Local Mob | 0.90 | $-10%$ scale reduction |
| 2 Extra Local Mobs | 0.85 | $-15%$ scale reduction |
| 3 Extra Local Mobs | 0.80 | $-20%$ scale reduction |
| 4 Extra Local Mobs | 0.75 | $-25%$ scale reduction |
| 5 Extra Local Mobs | 0.70 | $-30%$ scale reduction |
| 8 Extra Local Mobs | 0.55 | $-45%$ scale reduction |
| 10+ Extra Local Mobs | 0.40 | $-60%$ scale reduction (Floor) |
🌾 Spacious Pasture Recovery
When animals have space to roam ($\text{isOvercrowded} == \text{false}$ and $\text{extraLocalCount} < 3$): $$\text{recoveryScale} = \text{clamp}(\text{currentScale} \times 1.15, 0.25, 1.30)$$
