* Clickable button. When clicked, fields will be sent.
* `x`, `y` and `name` work as per field
* `w` and `h` are the size of the button
+* Fixed button height. It will be vertically centred on `h`
* `label` is the text on the button
* Position and size units are inventory slots
### Schematics
* `minetest.create_schematic(p1, p2, probability_list, filename, slice_prob_list)`
* Create a schematic from the volume of map specified by the box formed by p1 and p2.
- * Apply the specified probability values to the specified nodes in `probability_list`.
+ * Apply the specified probability and per-node force-place to the specified nodes
+ according to the `probability_list`.
* `probability_list` is an array of tables containing two fields, `pos` and `prob`.
* `pos` is the 3D vector specifying the absolute coordinates of the
node being modified,
- * `prob` is the integer value from `0` to `255` of the probability (see: Schematic specifier).
+ * `prob` is an integer value from `0` to `255` that encodes probability and
+ per-node force-place. Probability has levels 0-127, then 128 is added to
+ encode per-node force-place.
+ For probability stated as 0-255, divide by 2 and round down to get values
+ 0-127, then add 128 to apply per-node force-place.
* If there are two or more entries with the same pos value, the
last entry is used.
* If `pos` is not inside the box formed by `p1` and `p2`, it is ignored.
* If `probability_list` equals `nil`, no probabilities are applied.
- * Slice probability works in the same manner, except takes a field
- called `ypos` instead which
- indicates the y position of the slice with a probability applied.
+ * Apply the specified probability to the specified horizontal slices according to the
+ `slice_prob_list`.
+ * `slice_prob_list` is an array of tables containing two fields, `ypos` and `prob`.
+ * `ypos` indicates the y position of the slice with a probability applied,
+ the lowest slice being `ypos = 0`.
* If slice probability list equals `nil`, no slice probabilities are applied.
* Saves schematic in the Minetest Schematic format to filename.
* `set_clouds(parameters)`: set cloud parameters
* `parameters` is a table with the following optional fields:
* `density`: from `0` (no clouds) to `1` (full clouds) (default `0.4`)
- * `color`: basic cloud color, with alpha channel (default `#fff0f0e5`)
- * `ambient`: cloud color lower bound, use for a "glow at night" effect (default `#000000`)
+ * `color`: basic cloud color with alpha channel, ColorSpec (default `#fff0f0e5`)
+ * `ambient`: cloud color lower bound, use for a "glow at night" effect.
+ ColorSpec (alpha ignored, default `#000000`)
* `height`: cloud height, i.e. y of cloud base (default per conf, usually `120`)
* `thickness`: cloud thickness in nodes (default `16`)
- * `speed`: 2D cloud speed + direction in nodes per second (default `{x=0, y=-2}`)
+ * `speed`: 2D cloud speed + direction in nodes per second (default `{x=0, z=-2}`)
* `get_clouds()`: returns a table with the current cloud parameters as in `set_clouds`
* `override_day_night_ratio(ratio or nil)`
* `0`...`1`: Overrides day-night ratio, controlling sunlight to a specific amount
* `tool_capabilities`: capability table of used tool (can be `nil`)
* `dir`: unit vector of direction of punch. Always defined. Points from
the puncher to the punched.
+ `on_death(self, killer)`
+ * Called when the object dies.
+ * `killer`: an `ObjectRef` (can be `nil`)
* `on_rightclick(self, clicker)`
* `get_staticdata(self)`
* Should return a string that will be passed to `on_activate` when
