EntityFunctions

src/entityFunctions.ts

Helpers for entity state, health parsing, and distance calculations. Several methods are version-sensitive because Minecraft stores metadata differently across releases.

Constructor

Signature	Description
`new EntityFunctions(bot)`	Creates the helper object and selects the health metadata slot based on bot version.

Methods

Method	Returns	Description
`isMainHandActive(entity?)`	`boolean`	Checks whether the entity metadata indicates main-hand use.
`isOffHandActive(entity?)`	`boolean`	Checks whether the entity metadata indicates off-hand use.
`getHealth(entity?)`	`number`	Returns health from entity metadata, falling back to bot health when needed.
`getHealthFromMetadata(metadata)`	`number`	Reads health directly from a full metadata array.
`getHealthChange(packetMetadata, entity)`	`number`	Computes health delta from packet metadata versus current entity metadata.
`entityDistance(entity)`	`number`	Distance between the bot and the target entity.
`eyeDistanceToEntity(entity)`	`number`	Distance from the bot's eye position to the entity's AABB.
`eyeDistanceBetweenEntities(first, second)`	`number`	Distance from the first entity's eye position to the second entity's AABB.

Notes

healthSlot is derived from the bot's Minecraft version.
Distance helpers use AABBUtils to account for entity hitboxes instead of treating entities as points.
