|
|
This function combines another BlockArea into the current object.
|
|
The a_RelX, a_RelY and a_RelZ parameters specify the coords of this BA where a_Src should be copied.
|
|
If both areas contain baBlockEntities, the BEs are merged (with preference of keeping this' ones) (MergeBlockEntities()).
|
|
If only this contains BEs, but a_Src doesn't, the BEs are checked after merge to remove the overwritten ones and create
|
|
the missing ones (UpdateBlockEntities()).
|
|
The strategy parameter specifies how individual blocks are combined together, using the table below.
|
|

|
| area block | result |

So to sum up:
|
|
- msOverwrite completely overwrites all blocks with the Src's blocks
|
|
- msFillAir overwrites only those blocks that were air
|
|
- msImprint overwrites with only those blocks that are non-air
|

Special strategies (evaluate top-down, first match wins):

|

|

|
| A | * | A | Everything else is left as it is

msSpongePrint:

Used for most generators, it allows carving out air pockets, too, and uses the Sponge as the NOP block
|
|
| area block | |
|
|
| this | Src | result |

|
|
| A | sponge | A | Sponge is the NOP block

msDifference:
|

Used to determine the differences between two areas. Only the differring blocks are preserved:

|

|
|
+------+-------+--------+
|
|
| A | A | air | Same blocks are replaced with air
|
|
| A | non-A | A | Differring blocks are kept from "this"
|
|
|
|
msSimpleCompare:
|
|
Used to determine the differences between two areas. Blocks that differ are replaced with stone, same blocks are replaced with air
|
|
| area block | |
|
|
| this | Src | result |
|

+------+-------+--------+
|

| A | A | air | Same blocks are replaced with air

msMask:

Combines two areas, the blocks that are the same are kept, differing ones are reset to air
|
|
| area block | |
