cBlockArea remembers its origin (MinX, MinY, MinZ coords in the Read() call) and therefore supports absolute as well as relative get / set operations. Despite that, the contents of a cBlockArea can be written back into the world at any coords.
cBlockArea can hold any combination of the following datatypes:
Typical usage:
The strategy parameter specifies how individual blocks are combined together, using the table below.
| area block | result | |||
|---|---|---|---|---|

| air | air | air | air | air |
| A | air | air | A | A |
| air | B | B | B | B |
| A | B | B | A | B |
So to sum up:
Special strategies:
