# Hunger with HUD bar [`hbhunger`]
* Version: 0.6.0
## 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.

Using the mod:
--------------
This mod changes the HUD of Minetest.
It improves the apperance of the health and breath bar and adds a more fancy hotbar. Furthermore it adds a
custom crosshair, an armor bar (only for 3darmor mod) and a hunger bar. It includes also a mechanic for hunger.
You can create a "hud.conf" to customize the positions of health, hunger, armor and breath bar. Take a look at "hud.conf.example" to get more infos.
!!NOTICE: Keep in mind if running a server with this mod, that the custom position should be displayed correct on every screen size!!
Hunger:
This mod adds hunger to the game. You can disable this by setting "HUD_HUNGER_ENABLE = false" in "hud.conf", or "hud_hunger_enable = false" in minetest.conf. In case of conflict hud.conf configuration is dominant.
Currently supported food:
- Apples (default)
- Animalmaterials (mobf modpack)
- Bread (default)
- Bushes
- bushes_classic
- Dwarves (beer and such)
- Docfarming
- Fishing
- Farming plus
- Food
- fruit
- Glooptest
- Mobfcooking
- Mooretrees
- Mtfoods
- mushroom
- mush45
- Seaplants (sea)
- Simple mobs
Example: 1 apple fills up the hunger bar by 1 bread, 1 bread (from farming) 2 breads in bar.
Altough it show 20 hunger points (10 breads) in hunger bar you can fill it up to 30 points. (5 breads not shown then)

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.

[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.
hudbars_bar_type (HUD bars style) enum progress_bar progress_bar,statbar_classic,statbar_modern
# 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.
