for example. Can also generate a decoration of random height between a specified lower and
|
||||
upper bound. This type of decoration is intended for placement of grass, flowers, cacti,
|
||||
papyrus, and so on.
|
||||
- schematic
|
||||
Copies a box of MapNodes from a specified schematic file (or raw description). Can specify a
|
||||
probability of a node randomly appearing when placed. This decoration type is intended to be used
|
||||
for multi-node sized discrete structures, such as trees, cave spikes, rocks, and so on.
|
||||
|
||||
Schematic specifier
|
||||
--------------------
|
||||
A schematic specifier identifies a schematic by either a filename to a Minetest Schematic file (.mts)
|
||||
or through raw data supplied through Lua, in the form of a table. This table must specify two fields:
|
||||
- The 'size' field is a 3d vector containing the dimensions of the provided schematic.
|
||||
- The 'data' field is a flat table of MapNodes making up the schematic, in the order of [z [y [x]]].
|
||||
In the bulk MapNode data, param1, instead of the typical light values, instead represents the
|
||||
probability of that node appearing in the structure. It is an integer with a value from 0-255; 0 means
|
||||
that node will always appear. If the probability value p is non-zero, then there is a
|
||||
(p / 256 * 100)% chance that node will appear when the schematic is placed on the map.
|
||||
Important note: Node aliases cannot be used for a raw schematic provided when registering as a decoration.
|
||||
|
||||
Schematic attributes
|
||||
-----------------
|
||||
Currently supported flags: place_center_x, place_center_y, place_center_z
|
||||
- place_center_x
|
||||
Placement of this decoration is centered along the X axis.
|
||||
- place_center_y
|
||||
Placement of this decoration is centered along the Y axis.
|
||||
- place_center_z
|
||||
Placement of this decoration is centered along the Z axis.
