 #### 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

+[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.

+# Syntax:
+# The setting has to be specified as a comma-seperated list of key=value pairs, where a key

+# 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.
