**Note**: `offset` _will_ adapt to screen DPI as well as user defined scaling
factor!
+The `z_index` field specifies the order of HUD elements from back to front.
+Lower z-index elements are displayed behind higher z-index elements. Elements
+with same z-index are displayed in an arbitrary order. Default 0.
+Supports negative values.
+
Below are the specific uses for fields in each type; fields not listed for that
type are ignored.
use `minetest.formspec_escape`.
For coloured text you can use `minetest.colorize`.
+Since formspec version 3, elements drawn in the order they are defined. All
+background elements are drawn before all other elements.
+`list` elements are an exception here. They are drawn last. This, however, might
+be changed at any time.
+
**WARNING**: do _not_ use a element name starting with `key_`; those names are
reserved to pass key press events to formspec!
be shown if the inventory list is of size 0.
* **Note**: With the new coordinate system, the spacing between inventory
slots is one-fourth the size of an inventory slot.
+* **Note**: Lists are drawn after every other element. This might change at any time.
### `list[<inventory location>;<list name>;<X>,<Y>;<W>,<H>;<starting item index>]`
be shown if the inventory list is of size 0.

slots is one-fourth the size of an inventory slot.

### `listring[<inventory location>;<list name>]`
### `scrollbar[<X>,<Y>;<W>,<H>;<orientation>;<name>;<value>]`
-* Show a scrollbar
+* Show a scrollbar using options defined by the previous `scrollbaroptions[]`
* There are two ways to use it:
1. handle the changed event (only changed scrollbar is available)
2. read the value on pressing a button (all scrollbars are available)
* `orientation`: `vertical`/`horizontal`
* Fieldname data is transferred to Lua
-* Value this trackbar is set to (`0`-`1000`)
+* Value of this trackbar is set to (`0`-`1000`) by default
* See also `minetest.explode_scrollbar_event`
(main menu: `core.explode_scrollbar_event`).
+### `scrollbaroptions[opt1;opt2;...]`
+* Sets options for all following `scrollbar[]` elements
+* `min=<int>`
+ * Sets scrollbar minimum value, defaults to `0`.
+* `max=<int>`
+ * Sets scrollbar maximum value, defaults to `1000`.
+ If the max is equal to the min, the scrollbar will be disabled.
+* `smallstep=<int>`
+ * Sets scrollbar step value when the arrows are clicked or the mouse wheel is
+ scrolled.
+ * If this is set to a negative number, the value will be reset to `10`.
+* `largestep=<int>`
+ * Sets scrollbar step value used by page up and page down.
+ * If this is set to a negative number, the value will be reset to `100`.
+* `thumbsize=<int>`
+ * Sets size of the thumb on the scrollbar. Size is calculated in the number of
+ units the thumb spans out of the range of the scrollbar values.
+ * Example: If a scrollbar has a `min` of 1 and a `max` of 100, a thumbsize of 10
+ would span a tenth of the scrollbar space.
+ * If this is set to zero or less, the value will be reset to `1`.
+* `arrows=<show/hide/default>`
+ * Whether to show the arrow buttons on the scrollbar. `default` hides the arrows
+ when the scrollbar gets too small, but shows them otherwise.
+
### `table[<X>,<Y>;<W>,<H>;<name>;<cell 1>,<cell 2>,...,<cell n>;<selected idx>]`
* Show scrollable table using options defined by the previous `tableoptions[]`
`{stack1, stack2, stack3, stack4, stack 5, stack 6, stack 7, stack 8, stack 9}`
* `output.item` = `ItemStack`, if unsuccessful: empty `ItemStack`
* `output.time` = a number, if unsuccessful: `0`
- * `output.replacements` = list of `ItemStack`s that couldn't be placed in
- `decremented_input.items`
+ * `output.replacements` = List of replacement `ItemStack`s that couldn't be
+ placed in `decremented_input.items`. Replacements can be placed in
+ `decremented_input` if the stack of the replaced item has a count of 1.
* `decremented_input` = like `input`
* `minetest.get_craft_recipe(output)`: returns input
* returns last registered recipe for output item (node)
Bans
----
-* `minetest.get_ban_list()`: returns the ban list
- (same as `minetest.get_ban_description("")`).
-* `minetest.get_ban_description(ip_or_name)`: returns ban description (string)
-* `minetest.ban_player(name)`: ban a player
-* `minetest.unban_player_or_ip(name)`: unban player or IP address
-* `minetest.kick_player(name, [reason])`: disconnect a player with a optional
+* `minetest.get_ban_list()`: returns a list of all bans formatted as string
+* `minetest.get_ban_description(ip_or_name)`: returns list of bans matching
+ IP address or name formatted as string
+* `minetest.ban_player(name)`: ban the IP of a currently connected player
+ * Returns boolean indicating success
+* `minetest.unban_player_or_ip(ip_or_name)`: remove ban record matching
+ IP address or name
+* `minetest.kick_player(name, [reason])`: disconnect a player with an optional
reason.
+ * Returns boolean indicating success (false if player nonexistant)
