fn can_hold_item(&self, _item_stack: &ItemStack) -> bool

Vanilla Mob.canHoldItem: whether this mob is willing to hold the item. The base mob holds anything; specific mobs narrow this down.

fn pick_up_item(&self, world: &Arc<World>, item_entity: &ItemEntity)

Vanilla Mob.pickUpItem: take a dropped item into this mob’s equipment.

fn equip_item_if_possible(&self, item_stack: ItemStack) -> ItemStack

Vanilla Mob.equipItemIfPossible: route item_stack to the slot its equippable component asks for (main hand otherwise), swap up when the target slot already holds worse gear, and drop the replaced piece by its drop chance. Returns the stack that was equipped, or empty when nothing was taken.

fn get_preferred_weapon_type(&self) -> Option<Identifier>

Vanilla Mob.getPreferredWeaponType: the item tag a mob favors for its main hand regardless of raw damage (a skeleton keeps its bow over a stronger sword). The base mob has no preference; specific mobs override it.

fn compare_weapons( &self, new_item_stack: &ItemStack, current_item_stack: &ItemStack, slot: EquipmentSlot, ) -> bool

Vanilla Mob.compareWeapons: keep a piece of the mob’s preferred weapon type over one that is not, otherwise prefer more attack damage, then the equal-item tiebreak.

fn approximate_attribute_with( &self, item_stack: &ItemStack, attribute: AttributeRef, slot: EquipmentSlot, ) -> f64

Vanilla Mob.getApproximateAttributeWith: the value of attribute this mob would have in slot while wearing item_stack, taking the mob’s base value (zero when it lacks the attribute) and folding in the item’s attribute modifiers.

fn can_replace_equal_item( &self, new_item_stack: &ItemStack, current_item_stack: &ItemStack, ) -> bool

Vanilla Mob.canReplaceEqualItem: the tiebreak when two pieces grade out equally, favoring more enchantments, then less damage, then a custom name.

fn tick_looting(&self)

fn mob_attack_damage_source( &self, weapon_item: &ItemStack, attacker: &SharedEntity, ) -> DamageSource

Builds the damage source for this mob’s melee attack: the weapon’s custom damage type if set, else its behavior’s item damage source, else the default mob-attack type.
