Entity Metadata

Overview

Entity metadata is stored in BindableMap<EntityMetadataType, EntityMetadata> where EntityMetadataType is the type of the metadata (duh) and EntityMetadata contains the actual data

EntityMetadata:

• type which is the type of the entity metadata
• writer which is the writer of the value (ex. EntityMetadataByteBufWriter.VAR_INT)
• value which is the actual value of the metadata

Usage

You can set entity's metadata by setting value in the metadata map that is part of the entity class:

//set player's pose to sleeping
player.metadata[EntityMetadataType.POSE] = EntityMetadata(EntityMetadataType.POSE, EntityMetadataByteBufWriter.POSE, EntityPose.SLEEPING)

---

You can also remove it like with any other mutable map:

player.metadata.remove(EntityMetadataType.POSE)

---

To set the STATE metadata type, you probably want to use the built-in utility function getEntityMetadataState which provides nice dsl builder syntax and returns EntityMetadata object:

player.metadata[EntityMetadataType.STATE] = getEntityMetadataState(player) {
    isGlowing = true
    isInvisible = false
    isFlying = true
}
