difficulty when joining the world

to an easier difficulty in difficult
situations

command will still work
Gameplay
Target selectors
@e
Targets entities
Can specify type of entity by entity
ID to either include or exclude with
[type=Chicken] or [type=!
Skeleton]
Example:
/ kill @e[r=50,type=Chicken]
- kills all chicken within a radius of
50 blocks
Example: / tp @e[r=5] ~ ~5 ~
- any entity within a radius of 5
blocks will be teleported five blocks
in the air\
Commands
/ blockdata
Modifies NBT data at a specific
coordinate. The <dataTag> merges
with the block at that position
Can be used to change the
contents of a chest
Usage:
/ blockdata <x> <y> <z> <dataTag>
/ clone
Clones all the blocks (not entities)
from a given area to a different
given area
Up to 4096 blocks can be copied
The clone can be masked or
replace - replace will copy every
block, masked will only copy non-
air blocks
Usage:
/ clone <x1> <y1> <z1> <x2> <y2> <z2> <x> <y> <z> [mode]
Example:
/ clone 1001 3 1002 1011 3 992 1001 5 992 masked
/ fill
Fills a given volume with a specified
block
Up to 4096 blocks can be filled
oldBlockHandling works like with /
setblock, but with additional
options: hollow to only fill the outer
layer of blocks and fill the inner
part with air, outline to fill the outer
layer of blocks and ignore the inner
part
Works similarly to /setblock
Usage:
/ fill <x1> <y1> <z1> <x2> <y2> <z2> <TileName> [dataValue] [oldBlockHandling] <dataTag>
Example:
/ fill 1001 3 1002 1011 5 992 wool 6 replace
Can filter certain blocks
Only if it’s used to fill in replace
mode with “normal” blocks.
It does not work when filling
with block entities.
Syntax:
/ fill [x] [y] [z] [x] [y] [z] [BlockName] [Data] replace [filterBlockName] [filterData]
/ particle
Spawns particles in a given area
It can also be relative to
entities.
Usage:

/ particle lava ~ ~1 ~ 1 1 1 0.5 2 @e[type=Chicken]
