+# Hunger with HUD bar [`hbhunger`]
+
+* Version: 0.7.1
+
+## Using the mod
+
+This mod adds a mechanic for hunger.
+This mod depends on the HUD bars mod [`hudbars`], version 1.4.1 or any later version
+starting with “1.”.
+
+## About hunger
+This mod adds a hunger mechanic to the game. Players get a new attribute called “satiation”:
+
+* A new player starts with 20 satiation points out of 30
+* Actions like digging, placing and walking cause exhaustion, which lower the satiation
+* Every 800 seconds you lose 1 satiation point without doing anything
+* At 1 or 0 satiation you will suffer damage and die in case you don't eat something
+* If your satiation is 16 or higher, you will slowly regenerate health points
+* Eating food will increase your satiation (Duh!)
+
+Important: Eating food will not directly increase your health anymore, as long as the food
+item is supported by this mod (see below).
+
+Careful! Some foods may be poisoned. If you eat a poisoned item, you may still get a satiation
+boost, but for a brief period you lose health points because of food poisoning. However,
+food poisoning can never kill you.
+
+## Statbar mode
+If you use the statbar mode of the HUD Bars mod, these things are important to know:
+As with all mods using HUD Bars, the bread statbar symbols represent the rough percentage
+out of 30 satiation points, in steps of 5%, so the symbols give you an estimate of your
+satiation. This is different from the hunger mod by BlockMen.
+
+You gain health at 5.5 symbols or more, as 5.5 symbols correspond to 16 satiation points.
+You *may* lose health at exactly 0.5 symbols, as 0.5 symbols correspond to 1-2 satiation points.
+
+## Supported food
+All mods which add food through standard measures (`minetest.item_eat`) are already
+supported automatically. Poisoned food needs special support.
+
+### Known supported food mods
+* Apple from Minetest Game [`default`]
+* Red and brown mushroom from Minetest Game [`flowers`]
+* Bread from Minetest Game [`farming`]
+* [`animalmaterials`] (Mob Framework (`mobf` modpack))
+* Bushes [`bushes`]
+* [`bushes_classic`]
+* Creatures [`creatures`]
+* [`dwarves`] (beer and such)
+* Docfarming [`docfarming`]
+* Ethereal / Ethereal NG [`ethereal`]
+* Farming Redo [`farming`] by TenPlus1
+* Farming plus [`farming_plus`]
+* Ferns [`ferns`]
+* Fishing [`fishing`]
+* [`fruit`]
+* Glooptest [`glooptest`]
+* JKMod ([`jkanimals`], [`jkfarming`], [`jkwine`])
+* [`kpgmobs`]
+* [`mobfcooking`]
+* [`mooretrees`]
+* [`mtfoods`]
+* [`mushroom`]
+* [`mush45`]
+* Seaplants [`sea`]
+* Simple mobs [`mobs`]
+* Pizza [`pizza`]
+* Not So Simple Mobs [`nssm`]
+
+### Supported mods without optional dependency (mods provide their own support)
+
+* Food ([`food`], [`food_basic`])
+* Sweet Foods [`food_sweet`]
+
+### Examples
+
+* Eating an apple (from Minetest Game) increases your satiation by 2;
+* eating a bread (from Minetest Game) increases your satiation by 4.

+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)`
+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`: This is optional; You can specify an alternative format string display the final text on the HUD bar. The default format string is “`%s: %d/%d`” (in this order: Label, current value, maximum value). See also the Lua documentation of `string.format`.
+
+#### 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.

+# HUD bars
+
+## Description
+This mod changes the HUD of Minetest. It replaces the default health and breath
+symbols by horizontal colored bars with text showing the number.
+
+Furthermore, it enables other mods to add their own custom bars to the HUD,
+this mod will place them accordingly.
+
+**Important**: Keep in mind if running a server with this mod, that the custom
+position should be displayed correctly on every screen size.
+
+## Current version
+The current version is 1.11.0.
+
+This software uses [semantic versioning](http://semver.org), as defined by version 2.0.0 of the SemVer
+standard.
+
+## Settings
+This mod can be configured quite a bit. You can change HUD bar appearance, offsets, ordering, and more.
+Use the advanced settings menu in Minetest for detailed configuration.
+
+## API
+The API is used to add your own custom HUD bars.
+Documentation for the API of this mod can be found in `API.md`.

+as of version 2.0.0 of the standard <http://semver.org/>.
+
+0.1.0
+-----
+- Initial release, forked from mod “Better HUD” [hud].
+
+0.2.0
+-----
+- Add API documentation
+
+0.3.0
+-----
+- Rename main table from “hud” to “hb” (affects function names!)
+- Arguments 3-4 of hb.change_hudbar can be nil for values which should not change
+- Add proper function hb.init_hudbar, replaces odd call to hud.hudtables[identifier].add_all
+- Update API documentation and fix mistakes
+- Use “hudbars.conf” instead of “hud.conf”
+
+0.4.0
+-----
+- New function: hb.get_hudbar_state to get information about the state of an active HUD bar, such as values, whether it is hidden, etc.
+- hb.change_hudbar has been optimized to call hud_change fewer times, which is hopefully good for networking
+- Rename hb.register_hudbar parameter “start_hide” to “start_hidden”
+- start_hidden parameter now finally works
+- Do not affect other HUD flags (crosshair, wielditem, etc.) when starting mod
+- Show error message when trying to call hb.init_hudbar or hb.change_hudbar with bad values
+- Update documentation
+- Lots of refactoring
+- Health and breath bar now use API
+
+1.0.0
+-----
+- Add new parameter start_hidden to hb.init_hudbar, specified whether HUD bar is hidden on start
+- Copy-editing of API.md and README.txt
+- Internal: Fix add_all weirdness
+
+1.0.1
+-----
+- Fix race condition causing crash at start of server
+
+1.0.2
+-----
+- Fix other HUD elements disappearing for rejoining players
+- Remove pointless delays for initializing the HUD for new or rejoining players
+
+1.0.3
+-----
+- Adjust default HUD bars position for Minetest 0.4.12
+
+1.1.0
+-----
+- Add boolean minetest.conf setting support (hudbars_autohide_breathbar) to control whether the breath bar is automatically hidden when full (default: yes)
+
+1.2.0
+-----
+- New setting: hudbars_sorting. You can now manually sort all the HUD bars. Useful if you don't like automatic order
+- New setting: hudbars_bar_type. You now can change the appearance of the HUD bars.
+- New HUD bar types, slightly experimental: Classic statbars and modern [hud]-style statbars
+- New experimental/unfinished setting: hudbars_alignment_pattern: You can now make the HUD bars stack vertically instead of the current zig-zag pattern. Note you probably need to change source code to productively use this feature
+- Various position-related HUD bar settings (see README.txt)
+- Remove hudbars.conf support and hudbars.conf.example (was never officially supported anyways)
+
+1.2.1
+-----
+- Fix crash when enable_damage is changed in mid-game
+
+1.3.0
+-----
+- Make all settings avaialbe in Minetest's advanced settings menu
+- Fix HUD bars overlap when both hudbars_tick and hudbars_vmargin were set
+- Use Markdown syntax in readme file
+- Fix some factual mistakes in readme file
+- Add metadata: mod.conf, description.txt, screenshot.png
+
+1.4.0
+-----
+- Allow to change HUD bar images and label after it has been registered
+- Minor API.md correction
+
+1.4.1
+-----
+- Fix bug in hb.change_hudbar being a no-op if new_value and new_max value are nil
+
+1.5.0
+-----
+- Portuguese translation by BrunoMine
+
+1.5.1
+-----
+- Fix critical bug: Mod does not work with both intllib and mod security enabled
+- Update screenshot to use new 3:2 aspect ratio

+[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.

+# If enabled (default), the breath indicators in the HUD will be automatically hidden shortly
+# after the breath has been filled up. Otherwise, the breath will always be displayed. 
+hudbars_autohide_breath (Automatically hide breath indicators) bool true
+
+# 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.
+#    - stack_up:   The HUD bars are stacked vertically, going upwards.
+#    - stack_down: The HUD bars are stacked vertically, going downwards.
+hudbars_alignment_pattern (HUD bars alignment pattern) enum zigzag zigzag,stack_up,stack_down
+
+# 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.
