Editing Target selectors (section)

===Selecting targets by volume===

: <code>[dx=<value>,dy=<value>,dz=<value>]</code> — Filter target selection based on their x-difference, y-difference, and z-difference from some point, as measured by entities' hitboxes {{in|java}} or by their feet {{in|bedrock}}. Cannot duplicate any one of these three arguments.
: This can be interpreted as creating a rectangular volume defined by an initial position (<x>,<y>,<z>) and diagonal vector (<dx>,<dy>,<dz>), then selecting all entities whose hitboxes are at least partially contained by that volume {{in|java}}, or whose feet are within that volume {{in|bedrock}}. If the positional arguments are left out, the selection is interpreted as originating from the position of the command's execution. Any values are allowed, including signed and fractional numbers.
: Note that <code>dx</code>,<code>dy</code>,<code>dz</code> specify ''signed differences'' from the given coordinate. They do not specify a separate coordinate, nor do they extend in both the positive and negative directions.
: Additionally, when any volume argument is present, the rest are assumed to equal zero unless otherwise defined.

: Examples {{in|java}}:
:* <code>@e[x=1,dx=4,y=2,dy=5,z=3,dz=6]</code> — Select all entities whose hitbox collides with the block region (1~5, 2~7, 3~9) (or, mathematically speaking, the region that is {(x,y,z)∈R<sup>3</sup>|x∈[1.0,5.0),y∈[2.0,7.0),z∈[3.0,9.0)}).
:* <code>@e[x=1,y=2,z=3,dx=0,dy=0,dz=0]</code> — Select all entities whose hitbox contains the point (1,2,3).

: Examples {{in|bedrock}}:
:* <code>@e[x=1,dx=4,y=2,dy=5,z=3,dz=6]</code> — Select all entities whose feet are within the block region (1~5, 2~7, 3~9).
:* <code>@e[x=1,y=2,z=3,dx=0,dy=0,dz=0]</code> — Select all entities whose feet contains the point (1, 2, 3).

: It is possible to combine selection by distance and selection by volume, in which case the command select targets only within the overlap of both regions (within a certain radius of the volume's initial point and not outside the defined volume).
