Light Spread[szerkesztés | forrásszöveg szerkesztése]
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. This fact is significant for preventing hostile mob spawning. If a torch (level 14) is placed on a wall two blocks up from the floor, the light level on the floor one block away from the wall will be 11 (e.g. 14 minus 2 down, minus 1 south). If the torch were placed on the floor at floor level, then the light level on the floor one block away from the wall will be 13 (e.g. 14 minus 0 down, minus 1 south).
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 minimum number of light sources needed to prevent hostile mob spawning in the Overworld is difficult to determine because light decreases in all three dimensions. Given a perfectly flat plane or floor, the cheapest and easiest solution is to place torches on the floor in a diamond pattern, with a torch every 6th block (5 blocks in-between each torch diagonally).
Note: To get a nicer looking surface, these torches can be replaced with glowstone or pumpkin lanterns embedded into the floor. The same pattern may be used even though this reduces the light level on the floor by 1. This is because the glowstone and lanterns are 1 light level stronger than torches.
Here, the yellow "T" represents a torch on the floor, and number is the light level of adjacent floor blocks. Note that no block is less than light level 8, which means that hostile mobs cannot spawn. The green is only to highlight the 5 blocks between each torch.
To safely light hallways (or straight tunnels in a mine) using the same technique depends on the width of the hall. For a single block wide hall, the torches may be placed up to 13 blocks apart. A 3-block hall requires torches every 11 blocks down the center while a 5-block hall needs them every 9 blocks. An even numbered width hallway must have them staggered since there is no center row. For a 2-block hall, space them 12 blocks (plus 1 block offset.) A 4-block hall needs them every 10 blocks plus offset. A 6-block hall requires them to be spaced every 8 blocks and this works whether they are offset by 1 or 3 blocks, or even if they are placed against the walls. For halls that are 7 blocks wide, simply use the pattern above. For wider 'halls' you can adapt the same pattern. Just realize that this pattern requires torches to be placed right against the walls for complete coverage. If you wish to use glowstone, lanterns or redstone torches in the ceiling, you must space them closer according to the height of the hall. Place them closer by twice the height. E.g., instead of 13 blocks in a 1-block hall, if it is 2 blocks high, place them 9 blocks apart (13 - 2 - 2.)
However, when outdoors, if the ground level changes by even one block, this decreases light further, requiring a different pattern. Additionally, when indoors it may be more aesthetically pleasing to light sources along walls or attached to the ceiling. But this means that the light level will decrease from ceiling to floor, and the light level of the floor is used to calculate mobs spawning.
Light-filtering blocks[szerkesztés | forrásszöveg szerkesztése]
All other transparent blocks reduce the spread of light. 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.
|Pókháló||0 but diffuses sky light at the top-most block|
Leaves and cobwebs do not have any extra effect on block light, but they do diffuse sky light. The light level from sunlight or moonlight is the same in each block of air in the column of air above the highest obstruction in the column. When placed, leaves and cobwebs obstruct that light column so that the lowest air block above the leaves acts as other light sources do. As you descend below the leaves, the light level diminishes with distance like it would from other light sources such as torches. To control this effect, create an opaque 1×1 chimney with leaves at its opening above you.
Simított megvilágítás[szerkesztés | forrásszöveg szerkesztése]
Simított megvilágítás (which includes ambient occlusion as well as interpolating lighting across block faces) is the lighting engine added in Béta 1.3, with the help of MrMessiah. 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 engine blends lighting to add semi-realistic shadows and glowing from light sources. It darkens inside corners, resulting in small spaces appearing much darker. Before Béta 1.3, the feature could only be obtained by modifying the game with the help of MrMessiah's BetterLight mod.
The "Maximum" smooth lighting toggle fixes bugs with stairs. However, this is an optional toggle. The "Minimum" toggle increases performance, but does not fix the bug.

Minecraft has an extensive history when it comes to lighting. Classic's lighting model is simple and only checks whether a block is exposed to the sky. Indev's model is more complex and considers a block’s distance from the nearest sunlight and from the nearest light-emitting block. Alfa’s model is a refinement of Indev's, calculating sunlight and block-emitted light separately and using a different scale of light intensities. An earlier Béta update improved upon Alfa's model by adding the smooth lighting option, and in a later Béta update, the whole lighting engine was again rewritten to be much more efficient, have more detail, and be smooth in transition of lighting differentials.
Classic[szerkesztés | forrásszöveg szerkesztése]
In Classic, "sunlight" is emitted by the top edge of the map and will hit any block that is under it. 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.
Indev/Infdev[szerkesztés | forrásszöveg szerkesztése]
In Indev and Infdev versions there are 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, so for example 15 is 100% (Sablon:Frac) and 13 is 86.67% (Sablon:Frac).
Each block that emits light has its own luminance value and the light value diminishes by one level each block from its source. If the neighboring block already has a greater light value, it is ignored. The process is repeated for each block whose light value just changed.
During the day, sunlight has a maximum light value of 15. At dusk, it steadily decreases until it reaches a night-time minimum value of 4 representing moonlight. Sunlight is emitted by the top edge of the map, but does not diminish with distance from its “source”. A block lit by sunlight will be equally bright at any height or depth.
Lighting in Minecraft - Pocket Edition works the same as lighting in Minecraft.
Alfa - Béta 1.2_02[szerkesztés | forrásszöveg szerkesztése]
Full daylight provides the maximum brightness of 15. Each value below this is 80% as bright as the one above it. For example, 14 is 80% as bright as sunlight, and 13 is 64% bright. This means that Level 0 still has 0.815·100% = 3.5% of the maximum brightness.
Sunlight in Alfa has its own light array and a behind-the-scenes optimization to make dawn and dusk smoother: the amount of light from the sky is pre-calculated and saved along with the blocks, because it never needs to change except when blocks are added or removed. During dusk, nighttime, and dawn, a "darkness" value is subtracted from the sky to create the effects of different times of day.
In the Nether, light decreases by 10% each level, rather than the normal 20%. This means it will never be totally dark in the Nether. The minimum light value is 20.59%, providing a permanent dim ambience equivalent to normal world's level 8.
Béta 1.3 - Béta 1.7.3[szerkesztés | forrásszöveg szerkesztése]
Béta 1.8 - 1.4.7[szerkesztés | forrásszöveg szerkesztése]
In Béta 1.8, a new lighting engine was implemented. The new engine has added and changed the following:
- The lighting of an area is influenced by the type of light source that is lighting the block: moonlight gives a blue tint, torches and lava give a reddish tint, and complete darkness and sunlight are the same as before.
- Changes in lighting are now instant, and can be gradual as changes in the time of day and the state of rainfall now smoothly change the lighting value rather than individually updating the lighting of chunks one by one.
- Using the new instant lighting, non-sunlight lighting now subtly flickers, although this feature is purely cosmetic and has no effect on gameplay.
- Sunset is much more intense and realistic than before, and its intensity dims if the player turns away from it.
- At extreme depths, black fog closes in. At the bedrock level, a torch can no longer be seen from 11 squares distance. This effect is inhibited by proximity to open sky (i.e. the degree to which the place where you are standing would be lit by sunlight), whether or not the sun is currently up. Digging a shaft from the surface down to your room will allow you to see far, even at bedrock level.
- When inside the void, lighting operates similar to Classic, where objects in the void will remain at a constant brightness, regardless of how far they travel away from a light source, provided that they remain directly underneath an opening into the void. The brightness of the particular "column" of space is based on the current light level at level 0, the bottom bedrock layer. This applies to all entities, as well as particles.
- Additionally, sitting in the void underneath a shaft which allows sunlight directly into it will remove the void fog, regardless to whether is it daytime or not.
As of 1.5, there were several lighting optimizations, including more realistic lighting and lighting interacting correctly with slabs and stairs (Maximum smooth lighting). However, furnaces emitting light from all sides, and black spots in world generation were not fixed. As well, there are now three different levels of smooth lighting: Off, Minimum, and Maximum.
1.7.2[szerkesztés | forrásszöveg szerkesztése]
In snapshot 14w30a, the lighting engine was significantly improved, removing most black spots present in world generation.
In snapshot 14w34c, the void fog and particles were removed in order to improve performance.

Apróságok[szerkesztés | forrásszöveg szerkesztése]
- Hostile mobs can spawn in areas where there should be light, but there isn't. This is because the game thinks there is a light level of 0.
- Smooth Lighting is not apparent on the top of water or on paintings.
- A 21×21 square of opaque material is enough to spawn mobs in the shadow underneath.
- If zombies or skeletons are in water or in the low light levels caused by trees, they can survive through the daytime.
- The Halloween Update version Alfa 1.2.0 allowed monsters to spawn in higher light levels at lower depths, using the formula 16 − (Layer / 8). At level 8 and below, mobs could spawn even in sunlight. Notch reverted mob spawning to the original method in version Alfa 1.2.1, saying, "it was way too annoying. I have plans on what to do with this."
- In Minecraft 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.
