All entities from a plugin are in one object, for example minecraft:horse is at the key path .minecraft.horse An entity is described by an object with the following keys: * attitude: one of "friendly", "hostile", or "neutral". Omitted for non-mobs. * dimension: the “native” dimension of the mob. One of "overworld", "nether", or "end". Mobs may also spawn in other dimensions. * name: the display name for the entity * oldID: the string ID used for the entity before Minecraft snapshot 16w32a, if any * subtypes: an object mapping subtype IDs (defined by entities.json) to objects describing subtype variants.
