+After a HUD bar has been added, you can change the current and maximum value and other attributes on a per-player basis.

+
+The following parameters are less important and provided for styling the HUD bar after registration (if

-Minetest mod: HUD bars
-======================
-Version: 1.2.1
-
-This software uses semantic versioning, as defined by version 2.0.0 of the SemVer
-standard. <http://semver.org/>
-
-
-License of source code: WTFPL
------------------------------
-Author: Wuzzy (2015)
-Forked from the “Better HUD” [hud] mod by BlockMen.
-
-
-Using the mod:
---------------
-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.
-
-You can create a “hudbars.conf” file to customize the positions of the health and breath bars. Take a look at “hudbars.conf.example”
-to get more infos. The lines starting with “--” are comments, remove the two dashes to activate a setting. Settings which are not
-set will use a default value instead.
-
-
-IMPORTANT:
-Keep in mind if running a server with this mod, that the custom position should be displayed correctly on every screen size!
-
-Settings:
----------
-This mod can be configured by editing minetest.conf. Currently, the following setting is recognized:
-
-- hudbars_autohide_breath: A boolean setting, it can be either “true” or “false”. If set to “true”,
-  the breath bar will be automatically hidden shortly after the breathbar has been filled up. If set
-  to “false”, the breath bar will always be displayed. The default value is “true”.
-
-- hudbars_sorting: This setting allows you to specify the “slot” positions of the HUD bars manually.
-
-  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. The slot positions start (slot 0) at the
-  bottom (nearest to hotbar in default configuration) left side, the following slot 1 is at the right
-  side, slot `2` is on the right side again, but placed over the first HUD bar (slot 0), and it goes on,
-  in a zig-zag pattern.
-  All HUD bars to which no sorting rule 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.
-
-  Be careful not to use slot indices twice, or else different HUD bars will be drawn over each other!
-
-  If this setting is not set, by default the health and breath bar are displayed at slot positions 0 and 1,
-  respectively (health bar at left bottom-most positoin, breath bar right from it). All other HUD bars are
-  placed automatically.
-
-  Example value:
-    breath=0, health=1
-  This places the breath bar at the left side, and the health bar to the right side.
-
-- hudbars_bar_type: Specifies the style of bars. You can select between the default progress-bar-like bars and the good old statbars
-  like you know from vanilla Minetest. Note that the classic and modern statbars are still a little bit experimental.
-  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 [hud] mod.
-
-- hudbars_vmargin: The vertical distance between two HUD bars in pixels (default: 24)
-- hudbars_tick: The number of seconds between two updates of the HUD bars. Increase this number if you have a slow server (default: 0.1)
-
-Position settings:
-With these settings you can configure the positions of the HUD bars. All settings must be specified as a number.
-The pos settings are specified as a floating-point number between 0 to 1 each, the start_offset settings are
-specified as whole numbers, they specify a number of pixels.
-The left and right variants are used for the zig-zag mode. In the stack_up and stack_down modes, only the left variant is used for
-the base position
-
-- hudbars_pos_left_x, hudbars_pos_left_y: Screen position (x and y) of the left HUD bar in zigzag mode. 0 is left-most/top, 1 is right-most/bottom.
-	Defaults: 0.5 (x) and 1 (y)
-- hudbars_pos_right_x, hudbars_pos_right_y: Same as above, but for the right one.
-	Defaults: 0.5 and 1.
-- hudbars_start_offset_left_x, hudbars_start_offset_left_y: Offset in pixels from the basic screen position specified in hudbars_pos_left_x/hudbars_pos_left_y.
-	Defaults: -175 and -86
-- hudbars_start_offset_right_x, hudbars_start_offset_right_y: Same as above, but for the right one.
-	Defaults: 15 and -86

+[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.

+#    - 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.

+# (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.
