Light (or lighting) in Minecraft affects visibility, mob "Monster" redirects here. For the mob called "monster" in the code, see Human. Mobs are living, moving game entities. The term "mob" is short for "mobile". 1] Contents 1 Spawning 2 Behavior 3 List of spawning, and plant Plants are Minecraft s representation of plant life. They do not move, but some can grow and spread under the right conditions. Most plants can be planted and farmed. The growth of some plants may be growth.
- Even though hostile mobs spawn in light levels of 7 and lower, and thunderstorms allow a light level of 8, hostile mobs will still spawn during a thunderstorm, because it is dark enough.
- Rarely, a Lightning Bolt can emit a light level lower than 5.
- Charged Creepers will sometimes emit a light level that is the same as a Redstone Torch.
- When a player drinks a Potion of Night Vision, light sources (excluding the sun), gain a dim color.
- In Minecraft`s source code, the luminescences are defined using the floating point values in the third column. In a weird quirk, these floating point numbers are fractions of 16, but are multiplied by 15 to get the integer light value.
- This means that both 0/16 and 1/16 (0.0 and 0.0625) correspond to the integer light value 0.
There are 16 light levels, which are specified by an integer from 0 (the minimum) to 15 (the maximum). The game uses the light level of a block See the various blocks found in Minecraft. For the blocking with shields that reduces damage when performed, see Blocking. All blocks Blocks are the basic units of structure in Minecraft. Contents 1 to compute the brightness of a given block.
The brightness of a block depends on both the level of light from other blocks and the level of sky light. Note "sky light" here is not reduced at night, instead the brightness curve itself changes based on the time. In this it matches the sky lighting value on the debug screen Java Edition Only Screenshot showing the debug information "Debug" redirects here. For world type, see Debug mode. The debug screen is triggered when the F3 key is pressed. It shows the chunk cache, the memory .
In general, lighting due to blocks results in a higher brightness, which is balanced by the fact that light due to blocks effectively starts at 14 (solid light-source blocks emit a level of 15, but that`s for the light source block itself) while sky-light brightness is 15 outdoors. Light due to blocks also tends towards orange in the middle ranges, while sky light in the Overworld The Overworld, as seen in an extreme hills and a forest biome The Overworld is the dimension in which all players begin their Minecraft journey.

- Brightness here refers to ITU-R BT.601 luminance value (luma)
The light from light-emitting blocks decreases by one light-level for each meter (block) of distance from the light source. Note that this applies to each of the 3 axes including N/S, E/W, and up/down. In other words, light decreases diagonally by "taxicab distance", or the sum of the distance along each axis. This means that if a torch (level 14) is placed on the floor, the light level on the adjacent floor blocks in all four direction will be 13 while the diagonal blocks in all four directions will have light level 12 (e.g. 14 minus 1 south, minus 1 east). Along a floor, this effect produces a diamond-shaped pattern of illumination around the light source. Remember, light decrease takes place in three dimensions. This means that if a torch (level 14) is placed on a wall one block up from the floor, then the block on the floor that is diagonally one block way will have a light level of 11 (e.g. 14 minus 1 south, minus 1 east, minus 1 down).

- The relevant light level is that in the air block above it. "Partially transparent" blocks are those that reduce light by at least 3 levels (2 in addition to the normal propagation reduction), such as water or ice.

The following values are the amount each block decreases the light value. The light emitted decreases by one for each block of distance from the light source, more depending on the block through which it passes.
Effects of light
Note: Keep in mind that light level is only one of the considerations that apply to mob spawning and plant growth.
- These restrictions only apply when spawning from a monster spawner, and not from a Silverfish block.
Smooth lighting (which includes ambient occlusion as well as interpolating lighting across block faces) is a lighting engine that blends light levels and darkens corners to add semi-realistic shadows and glowing from light sources.
This lighting engine is set on by default, and can be set to minimum, maximum, or off by accessing Video Options from the Options menu.
|?||The lighting engine in Classic was very simple, since there were only two light levels, bright and dark. "Sunlight" is emitted by the top edge of the map and will hit any block that is under it, regardless of distance. It will pass through transparent blocks to light blocks underneath. Blocks that do not receive light are in a dim shadow that remains at the same level of brightness no matter how far they are from a light source.|
|0.31||Added 16 degrees of brightness, with a maximum of 15 for full daylight and a minimum of 0 for almost complete darkness. Brightness is a linear scale and represents its value divided by 15; for example 15 is 100% (15⁄15) and 13 is 86.67% (13⁄15).|
|Sunlight now has a maximum light value of 15, and steadily decreases from dusk, until it reaches a night-time minimum value of 4, representing moonlight.|
|?||Lighting is no longer linear.|
|Each brightness value below 15 is 80% as bright as the one above it. For instance, 14 is 80% as bright as 15, and 13 is 64% as bright as 15.|
|Sunlight now has its own light array and optimizations to make dawn and dusk smoother. During dusk, nighttime, and dawn, a "darkness" value is subtracted from the sky to create the effects of different times of day.|

OverviewThere are 16 levels of light, the highest being produced by Sunlight. Light is decreased (or blocked entirely) when a block is situated in front of a light source. The block which decreases light the most is the base of a piston. The light level of a block affects whether or not certain Hostile Mobs will spawn on it.
Levels of Light
The light level determines if hostile or passive mobs will spawn. For example, a Cow will spawn in light level 7 or higher on Grass blocks. This is also the case for Pigs, Chickens and Sheep. Hostile mobs, such as Skeletons and Zombies, will spawn in light levels 7 or lower. A player can keep Hostile mob from spawning in an area by lighting up the area with torches or other light-emitting objects.
List of light levels in Minecraft:
15: Sunlight, Jack o` Lanterns, Beacons, End Portal Blocks, Fire, Glowstone, Lava, Active Redstone Lamps, Sea Lanterns
13: Active Furnace
12: Sunlight (during rain or snowfall), Glowing Obsidian (Pocket Edition only)
11: Nether Portal blocks
9: Redstone Ore (when touched)
8: Sunlight (during thunderstorms), Ender Chests
7: Powered Redstone Torches, Redstone Torch
1: Brewing Stands, brown mushrooms, Dragon Eggs, End Portal Frames
Smooth lighting is the lighting engine added in Beta 1.3. This lighting engine is on by default (it is always on in Minecraft: Pocket Edition), and can be set to maximum, minimum or off by accessing Video Options from the Options menu.
The engine blends lighting to add semi-realistic shadows and glow from light sources. It darkens inside corners, resulting in small spaces appearing much darker. Before Beta 1.3, the feature could be only obtained by modifying the game with the help of MrMessiah`s BetterLife Mod.
The "maximum" smooth lighting toggle fixes bugs with stairs. However, this is an optional toggle. The "minimum performance" does not fix the bug.
Minecraft has been evolving over time, and the lighting system itself has changed along with it.
Smooth Lighting didn`t exist in Minecraft Classic. Instead, light spread on dim-lit areas. "Sunlight" was emitted by the top edge of the map and would hit any block that was under it. It would pass through transparent blocks to light blocks underneath. Blocks that did not receive light were in a dim shadow that remained at the same level of brightness, no matter how far the block was from a light source.
In Indev and Infdev versions, there were 16 levels of brightness: 0 for almost complete darkness, and a maximum of 15 for full daylight.
Alpha - Beta 1.2_02`
Lighting in Alpha through pre-Beta 1.3 worked similar to Indev and Infdev, except the light scale was not linear.
Beta 1.3 - Beta 1.7.3
Lighting from Beta 1.3 to Beta 1.7.3 worked the same as it was in Alpha, but was optimized to allow smooth lighting".
Black patches in world generation and structure generation were fixed in update 1.7.2.
