|
||
'''Debug mode''' usually refers to a [[world preset]] used to test [[block state]]s, block [[model]]s, and [[Resource pack#Textures|textures]].
|
||
|
||
Debug mode can also refer to a dimension generator type (<code>minecraft:debug</code>) that generates a block grid, which is used in the "Debug mode" world preset, and can also be used in [[custom dimension]].
|
||
|
||
Debug mode can also refer to a state of a world, if the overworld uses the "debug" generator, the world goes into the debug mode state. In this state, blocks can't be changed even in creative mode or with commands.
|
||
|
||
== Debug mode world preset ==
|
||
[[File:DebugModeButton.png|thumb|right|200px|Debug mode selected; note that all of the other world settings are unavailable.]]
|
||
|
||
To select the debug mode, hold the {{Keys|Alt}} key while clicking the "World Type" button in the world creation menu. Debug mode is the world type directly after [[Single Biome]], and just before the [[World preset|default preset]].
|
||
|
||
Upon selecting debug mode, the "Bonus Chest", "Generate Structures", "Allow Cheats" and "Data Pack" options are removed from the menu. The game mode is set to [[Spectator]], [[difficulty]] is locked on Peaceful, and cheats are enabled. The game rule {{cd|doDaylightCycle}} is forced to false, while other game rules are forced to default values.
|
||
|
||
== Debug generator ==
|
||
The <code>minecraft:debug</code> generator contains all [[block]]s, in all of their existing [[block states]], organized in a single world. The world updates automatically to include any new registered [[Java Edition data values|block IDs]] that are added. Therefore, this mode is useful not only to [[Mojang]] developers, but also to creators of [[resource pack]]s and [[mod]]s.
|
||

||
=== Block grid ===

||
<gallery style="float:right;">

|
||
</gallery>
|
||
|
||
Every block state generates only once. They are sorted in a grid spread across an [[altitude]] of Y=70. The block grid changes its size according to the number of blocks and block states available, roughly resembling a square (as of 1.14.2, 213 in width and 211 eastward), occupying the +X,+Z (southeast) quadrant.<ref>Due to a bug ({{bug|MC-122412|||WON'T FIX}}), the block grid was not a correct square, and in some versions the blocks in the southernmost and northernmost columns duplicate, and whether duplication occurs is related to the total number of block states.</ref>
|
||
|
||
A barrier floor at Y=60 also spawns, extending past the grid in all directions to the [[world boundary]]. Other than the barrier floor, the remainder of the map is empty.

|
||
== Debug mode state ==
|
||
Debug mode can refer to a state of the world. If the Overworld uses the "debug" generator, the world goes into the debug world state.
|
||
|
||
=== World generation ===
|
||
[[File:Debug World Type hellview 14w27b.png|thumb|View of the Nether debug world]]
|
||
[[File:Debug World Type endview 14w29b.png|thumb|View of the End debug world]]
|
||
|
||
If a [[Nether portal]] or [[End portal]] is used, or teleported using {{cmd|/execute}}, the player enter other dimensions. The sky, light level and other properties remain appropriate to the [[dimension]].
|
||
|
||
In this state, all the dimensions are forced to use the "debug" generator. The chunk rendering may not update by itself in these dimensions, resulting in the need to right-click a block to render a new chunk.
|
||
|
||
In the vanilla [[End]], the [[ender dragon]] and its [[end crystal]]s still spawn, although the dragon cannot break or interact with blocks.
|
||
|
||
=== World behavior ===
|
||
It is impossible to change, place or remove any block, even by the game itself.
|
||
|
||
Chunk's [[tick#Chunk tick|chunk tick]] (including random ticks) does not execute.
|
||
|
||
No entity spawns naturally.
|
||
|
||
Any block whose interactions do not change its [[block state]] can still be {{control|used|use}} (including [[chest]]s, [[bed]]s, [[cake]], etc.). Although a block's state cannot change, its [[block entity]] data can change, either through normal player interaction or with the use of the {{cmd|data}} command.
|
||
|
||
These unique properties of debug mode can cause certain blocks to behave in unexpected ways, though due to the arrangement of blocks next to one another, not all may be seen in every version:
|
||
|
||
* [[Water]] and [[lava]] cannot be removed by [[bucket]]s, but still fills an empty bucket in [[Survival]] mode. If the player empties the bucket, the lava or water blocks turn invisible.
|
||
* [[Bell]]s can still be rung.
|
||
* [[Cauldron]]s clean leather [[armor]] and [[banner]]s, but cannot be filled by buckets.
|
||
* Flying through a [[pressure plate]] with powered stated false, or a [[weighted pressure plate]] with power state 0, causes it to produce the pressure plate clicking sound every tick it is pressed.
|
||
* {{Control|Using}} a [[comparator]] in subtract mode causes the block in the direction opposite its <code>facing</code> property to drop as an item.
|
||
** <span style="color: red>'''Warning:'''</span> If that block is a repeater or a comparator, it drops an infinite amount of itself, likely crashing the game.
|
||
* Any summoned [[falling block]] drops as an item when it hits another block, rather than converting itself to a block.
|
||
* {{control|Using}} [[fence gate]]s, [[comparator]]s, deactivated [[button]]s, [[lever]]s, deactivated [[pressure plate]]s, [[door]]s, or [[trapdoor]]s does not move or change the block, but the sound still plays.
|
||
* Using a music disc on an empty jukebox does not change its block state but still plays the music normally.

== Issues ==
|
||
{{dablink|Note that any bugs relating to using game modes other than spectator are resolved as "Invalid" or "Won't Fix" due to the fact that the world type can be legitimately accessed only in spectator.}}
|
||
{{issue list}}
|
||
|
||
== Trivia ==
|
||
* The set [[biome]] for this mode is [[plains]] by default in the [[Overworld]].
|
||
* The [[sun]] is displayed as if it were the beginning of the day (time 1000), but the [[daylight cycle]] is disabled.
|
||
** Regardless, the time can still be adjusted with the use of the {{cmd|time}} command, and the daylight cycle can be toggled with the use of the {{cmd|gamerule doDaylightCycle}} command. The time can be also advanced from nighttime to sunrise with the use of a bed.
|
||
* Using a [[map]] does not create an accurate map of the blocks in the world.
|
||
* When the world type in the world creation screen is set to Default, clicking on the World Type button with both {{key|Shift}} and {{key|Alt}} are held down immediately changes the world type to Debug Mode.
|
||
* Experimental blocks generate even if the corresponding [[experiments]] are disabled.
|
||
** They can be obtained in the hotbar by pressing {{control|pick block}} while in [[Creative]] mode. They are labelled as "Disabled Item", cannot be placed and disappear when dropped.
