+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 0 to 255:
- A probability value of 0 means that node will never appear (0% chance).
Schematic attributes
---------------------
+See section Flag Specifier Format.
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.
The offset field specifies a pixel offset from the position. Contrary to position,
the offset is not scaled to screen size. This allows for some precisely-positioned
items in the HUD.
+Note offset WILL adapt to screen dpi as well as user defined scaling factor!
Below are the specific uses for fields in each type; fields not listed for that type are ignored.
Note: Future revisions to the HUD API may be incompatible; the HUD API is still in the experimental stages.
If odd, will end with a vertically center-split texture.
- direction
- offset: offset in pixels from position.
+ - size: If used will force full-image size to this value (override texture pack image size)
- inventory
- text: The name of the inventory list to be displayed.
- number: Number of items in the inventory to be displayed.
- item: Position of item that is selected.
- direction
+- waypoint
+ Displays distance to selected world position.
+ - name: The name of the waypoint.
+ - text: Distance suffix. Can be blank.
+ - number: An integer containing the RGB value of the color used to draw the text.
+ - world_pos: World position of the waypoint.

+Flag Specifier Format
+-----------------------
+Flags using the standardized flag specifier format can be specified in either of two ways, by string or table.
+The string format is a comma-delimited set of flag names; whitespace and unrecognized flag fields are ignored.
+Specifying a flag in the string sets the flag, and specifying a flag prefixed by the string "no" explicitly
+clears the flag from whatever the default may be.
+In addition to the standard string flag format, the schematic flags field can also be a table of flag names
+to boolean values representing whether or not the flag is set. Additionally, if a field with the flag name
+prefixed with "no" is present, mapped to a boolean of any value, the specified flag is unset.
+
+e.g. A flag field of value
+ {place_center_x = true, place_center_y=false, place_center_z=true}
+is equivalent to
+ {place_center_x = true, noplace_center_y=true, place_center_z=true}
+which is equivalent to
+ "place_center_x, noplace_center_y, place_center_z"
+or even
+ "place_center_x, place_center_z"
+since, by default, no schematic attributes are set.
