I need to display a HUD message which stays permanently on the screen and will update automatically, when some variable's value changes.
Example Plugin:
Show Admins Online
I went through its source and found sync-hud, but I'm new to scripting and din't get the mechanism to use it.
Also it had some register_think value which I don't understand yet.
Tried to search about sync-hud but couldn't find any useful info.
Can someone explain how the sync-hud works?
