@ -35,6 +35,28 @@ This mod can be configured by editing minetest.conf. Currently, the following se
|
||||
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.
