A Grass Block is a block that generates naturally in the Overworld.
Grass blocks can only be obtained by mining them using a tool enchanted with silk touch, otherwise they will drop dirt.
|Breaking time (seconds)|
Grass grows spontaneously only during map generation. Afterward, it can only spread to a nearby dirt block. Grass spreading without player intervention depends heavily on the time of day. In order for a dirt block to accept grass from a nearby grass block, the following requirements must be met:
- The dirt block receiving grass must be within a 3×3×5 range of the source block where the source block is in the center of the second topmost layer of that range,
- The source block must have a light level of 9 or brighter directly above it,
- The dirt block must have a light level of at least 4 above it,
- Any block above the dirt block must not reduce light by 2 levels or more.
Light-reducing blocks include any opaque block, as well as lava, water, ice, and partially transparent blocks like stairs and single slabs. Grass blocks can grow under all other transparent blocks like glass, fences, torches, or pistons. Grass jumps directly from one block to a neighbor and is not affected by gaps or other blocks being "in the way". Grass blocks spread at random intervals and have an equal chance of spreading to any suitable dirt blocks that are in range. Because grass can spread as much as 3 levels downward, it tends to spread down slopes much faster than it spreads up them.
Grass will die and change to dirt after a random time if covered by any block that reduces the light level above the grass block to 4 or below, including any opaque blocks, or the surrounding area is brought to sufficient darkness. Transparent blocks directly over grass can't kill the grass directly, if the surrounding area provides sufficient darkness, the grass will die.
Grass blocks also change to dirt when sheep "eat" them.
- Animals will occasionally spawn on grass blocks that have light level 9 or brighter in the space directly above. This is quite rare and requires that there be few other animals nearby. Most animals are instead created along with the terrain.
- Passive mobs tend to wander towards grass blocks. They also wander towards light, but they ignore light over grass blocks and prefer them to any light levels below 10.
- Bone meal used on Grass Blocks will grow tall Grass and flowers.
- Sheep "feed" on grass blocks by turning them into dirt.
- Sheep regrow wool when they "eat" a grass block.
- A growing or dying grass block can be detected by a BUD. Therefore, growth and death conditions can be used to create a redstone light sensor.
A grass block has the ID name
minecraft:grass. A grass block also has a block state which is expected to replace the functionality of block data in a future version (though grass block doesn't currently use its block data).
