Fox

Registry name

etfuturum:fox

Audit correction: previously written as etfuturum.fox (wrong separator — not a valid resource location). Evidence: core/proxy/CommonProxy.java:291 registerEntity(EntityFox.class, "fox", 22, ...)

Basic info

• Health: 10 HP
• Armor: None
• Size: 0.6 × 0.7 (width × height)
• Spawn conditions: Natural spawning only in BiomeDictionary.Type.CONIFEROUS biomes, weight 8, group 2–4. Foxes do not spawn in snowy or generic biomes. The red/snow variant is then chosen by EntityFox.Type.fromBiome(biome) at entities/EntityFox.java:331, not by a separate spawn entry. Evidence: core/proxy/CommonProxy.java:292 EntityRegistry.addSpawn(EntityFox.class, 8, 2, 4, EnumCreatureType.creature, BiomeDictionary.getBiomesForType(Type.CONIFEROUS));
• Drops: On death: drops whatever item it is holding in its mouth (if any). Default death drops follow EntityAnimal (nothing by default unless dropFewItems overridden — it is not in this class).
• Behaviour: Passive/tameable four-legged mob. Complex AI for hunting, sleeping, berry eating, and trust system.

Stats

Types

• Red Fox and Snow Fox: both are spawned from the same CONIFEROUS biome spawn entry with weight 8. The variant is selected per-spawn by EntityFox.Type.fromBiome(). So “snow fox spawns in snowy biomes / red fox spawns in normal biomes” is not how this mod works — a snowy coniferous biome yields snow foxes, any other coniferous biome yields red foxes. (Audit correction: the previous wording implied two independent biome-restricted spawn rules.)

Configuration gate

• Entity registration: ConfigEntities.enableFoxes, config key enableFoxes, default ON (configuration/configs/ConfigEntities.java:53).

Trust system

A fox can trust up to two players/entities. The first trusted UUID is the “owner”. Trusted entities:

• Do not trigger fleeing/aggression
• Can hand-feed breeding items
• Baby foxes inherit trust from parents

Behaviour details

Hunting

• Red fox: targets EntityChicken and EntityRabbit
• Snow fox: targets fish entities (not implemented in this version)
• Hunts by creeping (crouching, head-rolling animation), then jumping/chasing
• AIMoveToHunt: waits until target is far (>36 blocks), then starts the chase sequence
• AIJumpChase: full crouch + jump leap attack when in range

Sleeping

• Foxes sleep during daytime in shaded areas (below sky, path weight ≥ 0)
• Sleeping foxes stop all actions; woken by aggression, swimming, thunder, or nearby threats
• If a trusted player attacks something nearby, fox defends them

Eating

• Picks up nearby items automatically (items, not blocks)
• Holds one item in mouth; can swap by picking up another
• If holding a breeding item dropped by its owner, may follow the owner
• Eating plays a particle effect and sound

Breeding

• Breeding items: Sweet berries (if enableSweetBerryBushes config), otherwise wheat as fallback
• Two trusted players can breed; baby inherits random type from parents
• Baby foxes trust both parents

Daylight avoidance

• Flees from sun during daylight: seeks shade, stops wandering
• Will not sleep near occupied points of interest (village-related, not implemented here)

Equipment on spawn

~20% chance to spawn holding one of: emerald (5%), rabbit foot (10%), rabbit hide (10%), egg (15%), wheat (20%), leather (20%), feather (20%). Only spawned if rabbits enabled.

Notes

• Creature attribute: none (ordinary)
• Immune to sweet berry bush damage
• attackEntityAsMob: knockback + enchantment processing + fire aspect + biting sound
• interact: if breeding item → trigger love mode
• Baby chance on spawn: ~5% if nearby spawn limit not exceeded
• Can pick up and hold one item; spits out old item when picking up a new one (unless eating)
