The world generation in debug mode

Debug mode is a world type World Type is an option to change how worlds generate in Minecraft. Contents 1 World types 1.1 Computer and Pocket Editions 1.2 Computer and Console Editions 1.3 Computer Edition exclusive 1.4 Pocket Edition exclusive 1.5 used to test block states See the definition of the block states. For the files that determine block models, see Models#Block states. Block states are extra pieces of data that further define a block. Contents 1 List , block models Block models are used to depict all the blocks in the game, whereas item models are used to display the items in the players hand, on their head (helmets and hats), on the ground, in , and textures.

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 day-night cycle is disabled.
  • Regardless, the time can still be adjusted with the use of the /time command, and the day-night cycle can be toggled with the use of the /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.

Accessing

Debug mode selected; note that all of the other world settings are unavailable.

To select the debug mode, hold the ⃢₇₧ Shift key while clicking the "World Type" button in the world creation menu. Debug mode will then be the world type directly after Customized An example of custom terrain generation. Customized is a world type that replaces the normal varied terrain of the Overworld with custom features. Contents 1 Customization 1.1 Basic settings 1.2 Ore settings 1.3 Advanced settings , and just before Default World Type is an option to change how worlds generate in Minecraft. Contents 1 World types 1.1 Computer and Pocket Editions 1.2 Computer and Console Editions 1.3 Computer Edition exclusive 1.4 Pocket Edition exclusive 1.5 .

Upon selecting debug mode, the "Bonus Chest", "Generate Structures", and "Allow Cheats" options are removed from the menu. The game mode is set to Spectator Java Edition Only Spectator mode is a game mode which allows you to fly around and observe the world without interacting with it in any way. Spectator mode can be entered by using the command , and the difficulty Mobs in full armor are a common sight in higher difficulty levels. Difficulty is an option in Minecraft that has a direct impact on the ease of gameplay. Contents 1 World setting 1.1 Peaceful 1.2 is locked on peaceful; be that as it may, /gamemode and /difficulty will work as usual within the world.

Block grid

  The entire grid as seen from above. East is up.

The block grid is approximately 144ℂₗ148 in size, occupying the +X,+Z (southeast) quadrant, although the barrier Barrier Transparency Partial (lets light pass through) Luminance No Blast resistance 18,000,003 Tool None Renewable No Stackable Yes (64) Flammable No Drops Nothing Data value dec: 166 hex: A6 bin: 10100110 Name barrier See the floor extends past the grid in all directions to the world border World border First appearances See History Java Edition Only See the customizable border. For the physical edge of the playable world, see World boundary. For the phenomenon that existed before Beta 1.8, . Blocks are sorted in a grid spread across an altitude Chart lining up Y-coordinate values (left) to block layers (right). Altitude is a measurement of vertical distance, or distance along the Y-axis. Contents 1 Definition 2 Limits 3 Natural resources and altitude 3.1 The Nether of y=70, with a barrier Barrier Transparency Partial (lets light pass through) Luminance No Blast resistance 18,000,003 Tool None Renewable No Stackable Yes (64) Flammable No Drops Nothing Data value dec: 166 hex: A6 bin: 10100110 Name barrier See the floor at y=60. Other than the barrier floor, the remainder of the map is empty.

Starting at 0,0, the blocks are arranged first in rows of 75 block states from north to south, then in 73 rows from west to east, with an additional partial row of 10 states, following first the numerical data values of the blocks, then the block state names and values in alphanumeric order. There are 5,485 unique block states. Every block state generates only once.

Block behavior

It is impossible for the player The Player Health points 20 () Armor points Varies Attack strength Fist: 1 () Items: Varies Size Height: 1.8 Blocks Width: 0.6 Blocks While sneaking: Height: 1.65 Blocks Width: 0.6 Blocks While gliding: Height: 0.6 to break any block, even in game modes See general gameplay in Minecraft. For instructional material, see Tutorials. A fresh Survival game. Gameplay in most game modes of Minecraft consists mainly of adding and destroying a variety of different blocks in which they otherwise could. Likewise, placing blocks is impossible, and the /setblock, /clone and /fill commands cannot be executed.

Any block whose interactions do not change its block state See the definition of the block states. For the files that determine block models, see Models#Block states. Block states are extra pieces of data that further define a block.

Although a block`s state cannot change, its block entity A block entity (previously named tile entity) is extra data associated with a block, beyond the block ID and 4 extra bits of data that every block has. Usage edit | edit source] Block entities data can change, either through normal player interaction or with the use of the /blockdata command.

These unique properties of debug mode can cause certain blocks to behave in unexpected ways:

  • Activating those blocks schedules a block tick Nearly all video games (including Minecraft) are driven by one big program loop. Just as every gear in a clock is synchronized with the pendulum, every task involved in advancing a game simulation is synchronized for its own block, which drops one of itself because those blocks cannot be suspended in mid-air.

It will also produce an extremely loud sound from so many pressure plate sounds being played at once.
  • The pressure plate schedules a block tick Nearly all video games (including Minecraft) are driven by one big program loop. Just as every gear in a clock is synchronized with the pendulum, every task involved in advancing a game simulation is synchronized for itself, and drops an item because it cannot be suspended in mid-air.
    • Since it never changes to an activated pressure plate, it never stops receiving activation from the entities and/or items on it, and never stops scheduling block ticks.
  • Certain pressure plates, when activated, cause an error in the game output, stating that the dropped item entity has no entity.

  • If that block is a repeater or a comparator, it will drop 36 stacks of itself.
    • It will start to repeatedly schedule its own block-state-changing tick, which will fail continually a large number of times.
  • These types of blocks schedule a block tick Nearly all video games (including Minecraft) are driven by one big program loop. Just as every gear in a clock is synchronized with the pendulum, every task involved in advancing a game simulation is synchronized in the adjacent block.
  • If that block could not normally remain suspended in the air, it will drop one of itself as an item.
• Warning: placing a minecart on an unpowered detector rail will drop an infinite number of detector rails.
• Certain glass panes, iron bars and fences have incorrect hitboxes.
• Banners are entirely invisible.
• Any summoned falling_block entities will drop as an item when it hits another block, rather than converting itself to a block. Such a summoned falling block will immediately drop as an item, rather than fall any distance.
• If you use fence gates, comparators, deactivated buttons, deactivated pressure plates, doors or trapdoors, they will not move or change, but the sound will still play.
• Nether portals are visible, but the End portal is not.
• Shulker boxes are invisible until looked at.
