HUD definitions for Thirsty
|
|
|
|
Optionally from one of the supported mods
|
|
|
|
Any hud needs to define the following functions:
|
|
|
|
- thirsty.hud_init(player)
|
|
Initialize the HUD for a new player.
|
|
|
|
- thirsty.hud_update(player, value)
|
|
Display the new value "value" for the given player. "value" is
|
|
a floating point number, not necessarily bounded. You can use the
|
|
"thirsty.hud_clamp(value)" function to get an integer between 0
|
|
and 20.
