-API documentation for the HUD bars mod
-======================================
-
-## Introduction
-This API allows you to add, change, hide and unhide custom HUD bars for this mod.
-
-## Overview
-To give you a *very* brief overview over this API, here is the basic workflow on how to add your own custom HUD bar:
-
-* Create images for your HUD bar
-* Call `hb.register_hudbar` to make the definition of the HUD bar known to this mod
-* Call `hb.init_hudbar` for each player for which you want to use previously defined HUD bar
-* Use `hb.change_hudbar` whenever you need to change the values of a HUD bar of a certain player
-* If you need it: Use `hb.hide_hudbar` and `hb.unhide_hudbar` to hide or unhide HUD bars of a certain player
-
-## The basic rules
-In order to use this API, you should be aware of a few basic rules in order to understand it:
-
-* A HUD bar is an approximate graphical representation of the ratio of a current value and a maximum value, i.e. current health of 15 and maximum health of 20. A full HUD bar represents 100%, an empty HUD bar represents 0%.
-* The current value must always be equal to or smaller then the maximum 
-* Both current value and maximum must not be smaller than 0
-* Both current value and maximum must be real numbers. So no NaN, infinity, etc.
-* The HUD bar will be hidden if the maximum equals 0. This is intentional.
-* The health and breath HUD bars are hardcoded.
-
-These are soft rules, the HUD bars mod will not enforce all of these.
-But this mod has been programmed under the assumption that these rules are followed, for integrity.
-
-## Adding a HUD bar
-To make a new HUD bar known to this mod, you need …
-
-* … an image of size 2×16 for the bar
-* … an icon of size 16×16 (optional)
-* … to register it with `hb.register_hudbar`
-
-### Bar image
-The image for the bar will be repeated horizontally to denote the “value” of the HUD bar.
-It **must** be of size 2×16.
-If neccessary, the image will be split vertically in half, and only the left half of the image
-is displayed. So the final HUD bar will always be displayed on a per-pixel basis.
-
-The default bar images are single-colored, but you can use other styles as well, for instance,
-a vertical gradient.
-
-### Icon
-A 16×16 image shown left of the HUD bar. This is optional.
-
-### `hb.register_hudbar(identifier, text_color, label, textures, default_start_value, default_start_max, default_start_hidden, format_string, format_string_config)`
-This function registers a new custom HUD bar definition to the HUD bars mod, so it can be later used to be displayed, changed, hidden
-and unhidden on a per-player basis.
-Note this does not yet display the HUD bar.
-
-The HUD bars will be displayed in a “first come, first serve” order. This API does not allow fow a custom order or a way to set it
-manually in a reliable way. However, you can use the setting `hudbars_sorting` for this. See the advanced setting menu in Minetest
-for more information.
-
-
-#### Parameters
-* `identifier`: A globally unique internal name for the HUD bar, will be used later to refer to it. Please only rely on alphanumeric characters for now. The identifiers “`health`” and “`breath`” are used internally for the built-in health and breath bar, respectively. Please do not use these names.
-* `text_color`: A 3-octet number defining the color of the text. The octets denote, in this order red, green and blue and range from `0x00` (complete lack of this component) to `0xFF` (full intensity of this component). Example: `0xFFFFFF` for white.
-* `label`: A string which is displayed on the HUD bar itself to describe the HUD bar. Try to keep this string short.
-* `textures`: A table with the following fields:
- * `bar`: The file name of the bar image (as string). This is only used for the `progress_bar` bar type (see `README.txt`, settings section).
- * `icon`: The file name of the icon, as string. For the `progress_bar` type, it is shown as single image left of the bar, for the two statbar bar types, it is used as the statbar icon and will be repeated. This field can be `nil`, in which case no icon will be used, but this is not recommended, because the HUD bar will be invisible if the one of the statbar bar types is used.
- * `bgicon`: The file name of the background icon, it is used as the background for the modern statbar mode only. This field can be `nil`, in which case no background icon will be displayed in this mode.
-* `default_start_value`: If this HUD bar is added to a player, and no initial value is specified, this value will be used as initial current value
-* `default_max_value`: If this HUD bar is added to a player, and no initial maximum value is specified, this value will be used as initial maximum value
-* `default_start_hidden`: The HUD bar will be initially start hidden by default when added to a player. Use `hb.unhide_hudbar` to unhide it.
-* `format_string`: Optional; You can specify an alternative format string to use for the final text on the HUD bar. The default format string is “`@1: @2/@3`” (The “@” numbers are placeholders that have a meaning in this order: @1 = Label, @2 = current value, @3 = maximum value). Do *not* use minetest.translator on this string, the string will be translated by `hudbars`, but you still must put this string into the translation catalogue file.
-* `format_string_config`: Required if `format_string` is set. This allows to change which parameters to use in the format string. It's a table with these fields:
- * `textdomain`: Text domain of the format string, used by `minetest.translate`
- * `order`: Table that contains the order of the placeholders. It's also possible to remove placeholders. Default order: `{ "label", "value", "max_value" }`
- * `format_value`: Format string to apply when displaying `value`. Syntax is same as in `string.format`. Default: `"%d"`
- * `format_max_value`: Same as `format_value` but is applied to `max_value`
-
-#### Example
-Example (mostly) from `hbarmor` mod:
-
-```
-hb.register_hudbar("armor", 0xFFFFFF, minetest.translator("hbarmor", "Armor"), { icon = "hbarmor_icon.png", bgicon = "hbarmor_bgicon.png", bar = "hbarmor_bar.png" }, 0, 100, hbarmor.autohide, N("@1: @2%"), { order = { "label", "value" }, textdomain = "hbarmor" } )
-```
-
-Displays an armor HUD bar with a label of the form „Armor: 53%“. (`N` is a dummy function that returns its argument, used to make the string visible for translator scripts.)
-
-#### Return value
-Always `nil`.
-
-
-## Displaying a HUD bar
-After a HUD bar has been registered, they are not yet displayed yet for any player. HUD bars must be
-explicitly initialized on a per-player basis.
-
-You probably want to do this in the `minetest.register_on_joinplayer`.
-
-### `hb.init_hudbar(player, identifier, start_value, start_max, start_hidden)`
-This function initialzes and activates a previously registered HUD bar and assigns it to a
-certain client/player. This has only to be done once per player and after that, you can change
-the values using `hb.change_hudbar`.
-
-However, if `start_hidden` was set to `true` for the HUD bar (in `hb.register_hudbar`), the HUD bar
-will initially be hidden, but the HUD elements are still sent to the client. Otherwise,
-the HUD bar will be initially be shown to the player.
-
-#### Parameters
-* `player`: `ObjectRef` of the player to which the new HUD bar should be displayed to.
-* `identifier`: The identifier of the HUD bar type, as specified in `hb.register_hudbar`.
-* `start_value`: The initial current value of the HUD bar. This is optional, `default_start_value` of the registration function will be used, if this is `nil`.
-* `start_max`: The initial maximum value of the HUD bar. This is optional, `default_start_max` of the registration function will be used, if this is `nil`
-* `start_hidden`: Whether the HUD bar is initially hidden. This is optional, `default_start_hidden` of the registration function will be used as default
-
-#### Return value
-`true` on success, `false` otherwise.
-
-
-## Modifying a HUD bar
-After a HUD bar has been added, you can change the current and maximum value and other attributes on a per-player basis.
-You use the function `hb.change_hudbar` for this.
-
-### `hb.change_hudbar(player, identifier, new_value, new_max_value, new_icon, new_bgicon, new_bar, new_label, new_text_color)`
-Changes the values and the appearance of an initialized HUD bar for a certain player. `new_value`
-and `new_max_value` are the most important parameters as they specify the new current and maximum new values, you do not need
-to worry too much about the other parameters.
-
-The following parameters are less important and provided for styling the HUD bar after registration (if
-this is desired). The “styling” parameters parallel the parameters of `hb.register_hudbar`. It is
-recommended to not change the style of a HUD bar too often as this can be distracting or confusing
-for players.
-
-`new_value`, `new_max_value` `new_icon`, `new_bgicon`, `new_bar`, `new_label` and `new_text_color` can be
-`nil`; if one of them is `nil`, that means the value is unchanged. If all those values are `nil`, this
-function is a no-op.
-
-This function tries to minimize the amount of calls to `hud_change` of the Minetest Lua API
-(and thus, network traffic), when you only change the value and/or  maximum value. In this case,
-`hud_change` is only called if it is actually needed, e.g. when the actual length of the bar
-or the displayed string changed, so you do not have to worry about it. There is, however, no
-such network optimization for the “styling” parameters, so keep this in mind.
-
-#### Parameters
-* `player`: `ObjectRef` of the player to which the HUD bar belongs to
-* `identifier`: The identifier of the HUD bar type to change, as specified in `hb.register_hudbar`.
-* `new_value`: The new current value of the HUD bar
-* `new_max_value`: The new maximum value of the HUD bar
-* `new_icon`: File name of the new icon
-* `new_bgicon`: File name of the new background icon for the modern-style statbar
-* `new_bar`: File name of the new bar segment image
-* `new_label`: A new text label of the HUD bar. Note the format string still applies
-* `new_text_color`: A 3-octet number defining the new color of the text.
-
-#### Return value
-`true` on success, `false` otherwise.
-
-
-## Hiding and unhiding a HUD bar
-You can also hide custom HUD bars, meaning they will not be displayed for a certain player. You can still
-use `hb.change_hudbar` on a hidden HUD bar, the new values will be correctly displayed after the HUD bar
-has been unhidden. Both functions will only call `hud_change` if there has been an actual change to avoid
-unneccessary traffic.
-
-Note that the hidden state of a HUD bar will *not* be saved by this mod on server shutdown, so you may need
-to write your own routines for this or by setting the correct value for `start_hidden` when calling
-`hb.init_hudbar`.
-
-### `hb.hide_hudbar(player, identifier)`
-Hides the specified HUD bar from the screen of the specified player.
-
-#### Parameters
-* `player`: `ObjectRef` of the player to which the HUD bar belongs to
-* `identifier`: The identifier of the HUD bar type to hide, as specified in `hb.register_hudbar`.
-
-#### Return value
-`true` on success, `false` otherwise.
-
-
-### `hb.unhide_hudbar(player, identifier)`
-Makes a previously hidden HUD bar visible again to a player.
-
-#### Parameters
-* `player`: `ObjectRef` of the player to which the HUD bar belongs to
-* `identifier`: The identifier of the HUD bar type to unhide, as specified in `hb.register_hudbar`.
-
-#### Return value
-`true` on success, `false` otherwise.
-
-
-## Reading HUD bar information
-It is also possible to read information about existing HUD bars.
-
-### `hb.get_hudbar_state(player, identifier)`
-Returns the current state of the active player's HUD bar.
-
-#### Parameters
-* `player`: `ObjectRef` of the player to which the HUD bar belongs to
-* `identifier`: The identifier of the HUD bar type to hide, as specified in `hb.register_hudbar`.
-
-#### Return value
-On success, returns a table which holds information on the current state of the HUD bar. Note
-the table is a deep copy of the internal HUD bar state, it is *not* a reference; the information
-hold by the table is only true for the moment you called this function. The fields of this table are:
-
-* `value`: Current value of HUD bar.
-* `max`: Current maximum value of HUD bar.
-* `hidden`: Boolean denoting whether the HUD bar is hidden.
-* `barlength`: The length of the HUD bar in pixels. This field is meaningless if the HUD bar is currently hidden.
-* `text`: The text shown on the HUD bar. This fiels is meaningless if the HUD bar is currently hidden.
-
-If the player does not exist, returns `nil` instead.
-
-### `hb.get_hudbar_identifiers()`
-Returns a table of all currently registered HUD bar identifiers.

-[Appearance]
-# Specifies how the value indicators (i.e. health, breah, etc.) look. There are 3 styles
-# available. You can choose between the default progress-bar-like bars and the good
-# old statbars like you know from vanilla Minetest.
-# These values are possible:
-#   - progress_bar:    A horizontal progress-bar-like bar with a label, showing numerical value
-#                      (current, maximum), and an icon. These bars usually convey the most
-#                      information. This is the default and recommended value.
-#   - statbar_classic: Classic statbar, like in vanilla Minetest. Made out of up to 20
-#                      half-symbols. Those bars represent the vague ratio between
-#                      the current value and the maximum value. 1 half-symbol stands for
-#                      approximately 5% of the maximum value.
-#   - statbar_modern:  Like the classic statbar, but also supports background images, this
-#                      kind of statbar may be considered to be more user-friendly than the
-#                      classic statbar. This bar type closely resembles the mod
-#                      “Better HUD” [hud] by BlockMen.

-# This setting changes the way the HUD bars are ordered on the display. You can choose
-# between a zig-zag pattern (default) or a vertically stacked pattern.
-# The following values are allowed:
-#    - zigzag:     Starting from the left bottom, the next is right from the first,
-#                  the next is above the first, the next is right of the third, etc.

-# This setting allows you to specify the order of the HUD bars explicitly. If left empty
-# (the default), the health and breath indicators come first, additional indicators
-# may appear in any order. This setting is quite technical and normal users probably do not
-# need to worry about it.
-#
-# Syntax:
-# The setting has to be specified as a comma-seperated list of key=value pairs, where a key
-# refers to the identifier of a HUD bar and the value refers to the slot number of where the
-# HUD bar should be placed. The slot number must be an integer greater of equal to 0. Where
-# the HUD bars will be displayed exactly depends on the alignment pattern being used.
-# All HUD bars to which no order value has been applied will fill in all slots which have
-# not been occupied by the HUD bars specified in this setting, the slots will be filled in
-# from the lowest slot number.
-# Note that the order of those remaining HUD bars is not fixed, it basically just boils
-# down on which mod “came” first. Don't worry, the mod will still work perfectly fine, this
-# setting is entirely optional.
-# The identifier for the health bar is “health” and the identifier for the breath bar is
-# “breath”. For other HUD bars, you have to learn it from the mod which is supplying them.
-#
-# Be careful not to use slot indices twice, or else different HUD bars will be drawn over
-# each other!
-#
-# Example: “breath=0, health=1”
-# This makes the breath bar first and the health bar second, which is the opposite order
-# of the default one.

+# Real Suffocation [`real_suffocation`]
+Version: 1.0.0
+
+This mod adds suffocation. Suffocation is basically the same as drowning, but it
+is for being stuck inside solid blocks. If you're inside a solid block, you lose
+breath. If you lost your breath completely and you're still inside, you suffer
+10 HP (=5 “hearts”) of damage every 2 seconds.
+
+Specifically, suffocation is added to all blocks which:
+
+* Are solid
+* Are full cubes
+* Don't already have built-in damage or drowning damage
+* Are not excluded from suffocations by mods
+
+## Info for modders
+This mod will not add suffocation to all nodes with the group
+`disable_suffocation=1`.
+
+This mod adds the group `real_suffocation=1` to all nodes it has modified,
+this is mostly done for informational purposes.

+		- Drowning and damage: If node has set any of those explicitly, it probably knows why. We don't want to mess with it.
