Mass is derived by a cubic law: mass = BaseMassKg * (size / reference)^3, so a
juvenile/seedling weighs far less than an adult/mature and the size gene moves
mass too. New Mass helper + BaseMassKg on AnimalDef/PlantDef (deer 70, wolf 45,
boar 80, chicken 2.5; trees ~450, grass 0.4, etc.) and MassKg per unit on
ProductDef (foundation for hauling/inventory).
Wired into the sim (as chosen):
- Corpse meat is now proportional to body mass (Mass.MeatFraction), not raw
bodySize; Corpse gained a BodySize field so sprite scale stays independent of
meat (save/load updated).
- Kleiber metabolism: need decay x= (mass/refMass)^0.75, normalized per species,
so juveniles are cheaper to feed and heavier individuals eat a bit more,
without cross-species balance blowups (adults of typical size are unchanged).
- Carry capacity = mass x fraction x carry capability (Moving for quadrupeds;
Manipulation for future humans), shown in inspector/console. A dormant Carrier
component + Mass.LoadSpeedFactor hook slow an overloaded animal — the
foundation for item hauling.
Inspector shows body/plant weight (+carry); `animal`/`plant` console print mass.
Build + --check-content clean (42 genes, 41 traits). Not GUI-verified.
