[Tutorial][Work in progress] Hud elements

[guiismiti]

I will try it later.

The other purpose I had with it was to print variable messages to everyone (iprintln):

iprintln(&"BATTLEFIELD_MONSTERKILL", player);

Localized string:

REFERENCE           MONSTERKILL
LANG_ENGLISH        "&&1 ^7- ^1MONSTER KILL !!!"
LANG_GERMAN         "#same"
LANG_RUSSIAN        "#same"

Edit #1: I posted because it worked without the need of setplayernamestring(player). I copied the way it is on meatbot.
Edit #2: I tried izno's suggestion and it seems to be the best thing to do because (1) I only need 1 hud and (2) it is now perfectly centered. Thank you very much one again.
Just one small corretion, change

hud.value = x;

for

hud setValue(x);

And here is the code for a simple hud for headshots.
1. You must create the localized string for the label:

REFERENCE           HEADSHOT
LANG_ENGLISH        "^7Headshot: ^1&&1 ^7m"

2. On player connect, set self.headshothudid to 0;
3. Call this function with the killer

		displayHeadshot(distance, duration)
{
    self.headshothudid += 1;
    hudid = self.headshothudid;

    if(isdefined(self.headshothud))
    {
        self.headshothud destroy();
    }

    self.headshothud = newClientHudElem(self);
    self.headshothud.vertAlign = "top";
    self.headshothud.horzAlign = "center";
    self.headshothud.alignx = "center";
    self.headshothud.y = 120;
    self.headshothud setValue(distance);
    self.headshothud.label = &"FILENAME_HEADSHOT";
    self.headshothud.fontScale = 1.4;
    self.headshothud.alpha = 1;
    self.headshothud.sort = 5000;
    self.headshothud.color = (1, 1, 1);

    wait(duration);

    // if the player performed another headshot, there will be a new hud, which should not be affected/deleted by the old hud function
    if(self.headshothudid == hudid)
    {
        self.headshothud fadeOverTime(1);
        self.headshothud.alpha = 0;

        wait(1);

        if(self.headshothudid == hudid)
        {
            if(isdefined(self.headshothud))
            {
                self.headshothud destroy();
            }

            self.headshothudid = 0;
        }
    }
} 
	

Where FILENAME is the name of your localized strings file; duration is the duration of the hud (not counting the 1 second for fading); and distance(in meters) can be given as

distance = int(((distance(attacker.origin , self.origin)) * 0.0254) + 0.5);

(the +0.5 is because int will round, for example, 3.7 to 3, and I'd rather have it rounding it to the nearest int)

If you have libcod, you can also use Izno's unprecached setText() patch
