@ -152,3 +152,23 @@ Makes a previously hidden HUD bar visible again to a player.
#### Return value
Always `nil`.
## Reading HUD bar information
It is also possible to read information about an active HUD bar.
### `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
A table which holds information on the current state of the HUD bar. Note the table is a partial
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.
