Item

Items are objects which only exist within the player's inventory and hands - i.e., they cannot be placed in the game world. Some items simply place blocks or entities into the game world when used. They are thus an item when in the inventory and a block when placed. Some examples of objects which exhibit these properties are item frames, which turn into an entity when placed, and beds, which turn into a group of blocks when placed. When equipped, items and blocks briefly display their names above the HUD.

Items use item IDs while blocks use block IDs.
