+ ^ The drawn node level is read from param2, like flowingliquid
Nodes can also contain extra data. See "Node Metadata".
The "nodebox" node drawtype allows defining visual of nodes consisting of
arbitrary number of boxes. It allows defining stuff like stairs. Only the
-"fixed" box type is supported for these.
+"fixed" and "leveled" box type is supported for these.
^ Please note that this is still experimental, and may be incompatibly
changed in the future.
A box of a regular node would look like:
{-0.5, -0.5, -0.5, 0.5, 0.5, 0.5},
+type = "leveled" is same as "fixed", but y2 will be automaticaly setted to level from param2

Ore types
---------------
These tell in what manner the ore is generated.
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]]].
+Important: The default value for param1 in MapNodes here is 255, which represents "always place".
In the bulk MapNode data, param1, instead of the typical light values, instead represents the
probability of that node appearing in the structure.
-When passed to minetest.create_schematic, probability is an integer value ranging from -1 to 255:
- - A probability value of 0 means that node will always appear.
- - A probability value of -1 means the node will never appear.
+When passed to minetest.create_schematic, probability is an integer value ranging from 0 to 255:
+ - A probability value of 0 means that node will never appear (0% chance).
+ - A probability value of 255 means the node will always appear (100% chance).
- If the probability value p is greater than 0, then there is a (p / 256 * 100)% chance that node
will appear when the schematic is placed on the map.
-If registering a structure in the raw format, however, -1 is not a valid probability value; in order to
-have a node that is not placed, it must be CONTENT_IGNORE (the name for which is "ignore").
-
Important note: Node aliases cannot be used for a raw schematic provided when registering as a decoration.
