The world creation using the Debug Mode
Debug Mode is a world type used to test block models, states and textures. It is thereby useful not only to Mojang but also to creators of resource packs.
Accessing
To select the debug mode, hold the ⇧ Shift key while clicking "World Type". Debug Mode will then be directly after Customized, rather than Default being directly after Customized.
Properties
Debug mode contains all Minecraft blocks in all their different block states in a single world, in a grid across height y=70, with a barrier floor at y=60.
When choosing this world, the only game mode available is Spectator, and further options (such as generated structures, bonus chest, etc.) are unavailable; however, the game mode can be changed from inside the world with console commands. Breaking blocks is possible if the game mode is switched, however removing them is not; breaking blocks causes them to regenerate instantly. Some blocks allow right-click interactions (e.g. chests, and especially those blocks whose interactions do not change any block state), while others do not (e.g. levers, redstone repeaters).
If a Nether or End portal is used, the player will spawn in a Nether version of the debug world or the End credits will appear, depending on the portal used. If the End is reached through the Nether, an End version of the debug world generates, with the Ender Dragon flying around.
The block grid is approximately 180×180 in size, occupying the +X,+Z quadrant, although the barrier floor extends past the grid to the world border at X/Z ±29,999,984. Starting at 0,0, the blocks are arranged first in rows of 89 block states from north to south, then in 87 rows from east to west (with an additional partial row of 27 states), following the numerical data values of the blocks. There are a total of 7770 block states.

The '''dragon's breath''' is a [[brewing]] item that is used solely to make [[lingering potion]]s.
== Obtaining ==
The dragon's breath can be obtained by scooping up the [[ender dragon]]'s breath attack or the purple [[area effect cloud|effect clouds]] caused by [[dragon fireball]]s in an empty [[glass bottle]].
== Usage ==
=== Brewing ingredient ===
Dragon's breath may be added to any splash potion to upgrade it to a lingering potion, which can be used to create a lasting [[Lingering Potion#Area Effect Cloud|area effect cloud]], or to craft [[Arrow#Tipped arrows|tipped arrows]].
{{brewing
|name=[[Lingering Potion]]
|showname=1
|Dragon's Breath
|Any Lingering Potion
|base=Any Splash Potion}}
When put 2 or more dragon's breath in the brewing stand, after the brewing process, a glass bottle will drop as an [[Item (entity)|entity]]. However, if put only 1 dragon's breath in the brewing stand, after the brewing process, the glass bottle is consumed and cannot be retrieved.<ref>{{bug|MC-259583}}</ref>

A '''nautilus shell''' is an item that is used for crafting [[conduit]]s.
==Obtaining==
===Fishing===
{{main|Fishing#Junk and treasure}}
Nautilus shells can be rarely obtained as a treasure item from fishing. The drop chances of nautilus shells slightly increase with each level of [[Luck of the Sea]] on the [[player]]'s [[fishing rod]].
===Mob loot===
[[Drowned]] have a 3%{{only|java|short=1}} or 8%{{only|bedrock|short=1}} chance to spawn with a nautilus shell in their off-hand, and this nautilus shell always drops upon [[death]].
===Trading===
[[Wandering trader]]s may [[trading|sell]] a nautilus shell for 5 [[emerald]]s each, but they only sell 5 of them at a time.
==Usage==
{{IN|bedrock}}, a nautilus shell is one of the few items that can be held in the off-hand.
===Crafting ingredient===
{{crafting usage}}
=== Trading ===
Nautilus shells can be given to trident-wielding drowned with a chance for the drowned to pick up the shell and drop the trident.<sup>[''[[Bedrock Edition]] only'']</sup>

==Trivia==
*[[wikipedia:Nautilus|Nautilus]]es are animals that occupy deep oceans in the real world. However, they are absent in Minecraft and there are currently no plans to add nautilus [[mob]]s into the game.
*Because {{el|bedrock}} allows for Nautilus shells to be held in the off-hand (since drowned hold them), they are the only item in that version that can be put in the off-hand slot without having a specific function.

Issues
Issues relating to "Debug mode" are maintained on the bug tracker. Report issues there.
Note that any bugs relating to using other game modes than spectator are resolved as invalid due to the fact that the world type can only be legitimately accessed in spectator.
Trivia
- Every block creates only once. The remainder of the map is empty.
- Below the blocks the ground seems to be made of barriers, but as soon as one is broken another is placed, so you cannot pass through without using spectator mode.
- The sun is displayed, but there is no day/night cycle. The daytime can be adjusted using console commands.
- The biome is plains (except when in the Nether or the End).
- Activating buttons, levers, and pressure plates in debug mode will drop a resource of itself. However, pressure plates are not recommended to play with, as they will spew out tons of dropped plates, make weird noises, and will likely crash the game.
- By traveling through the end portal the sky will be dark, like the End, but the world type remains (see picture below in gallery)
