Direct item forms of blocks

Java Edition
The game prevents certain blocks from being obtained through normal gameplay methods, such as crafting, the creative inventory, the pick block key, and the Silk Touch enchantment. It also prevents such blocks from being given through less conventional methods, such as inventory editing, mods, and commands. Until 1.7.2 and 1.8, there had been a wide variety of blocks that could be edited into the inventory; over time, however, the game was updated so that these blocks became entirely unavailable, even though one utilized inventory editing. From Java Edition 1.13 onwards, blocks and items are completely different concepts, and numerical IDs no longer exist at all.

Currently, the game only accepts resource locations (such as ) in most commands, and uses these resource locations when assigning blocks to the inventory and save files. The old method of obtaining a block via numerical IDs is no longer an option because the numerical id method   is no longer used in command. In addition, the game automatically removes blocks with illegitimate resource locations from the inventory, so using inventory editors is also no longer an option. Furthermore, certain blocks with both block and item forms, such as, cannot be obtained in their block form in the inventory; however, since the game has a corresponding item named  , the item form is given instead. The only option is modifying game's class where registered items and ItemBlocks (direct item forms of blocks) in order to register and obtain them.

Despite never being intended to be obtainable, some of these could even be acquired in survival using unusual means.
