make a distance meter hud?

[Scripto]

I'm trying to make a distance meter HUD where when someone hits its says their name plus the player they killed and then their distance. i have this so far O_O

Callback_PlayerDamageHook( einflictor, eattacker, idamage, idflags, smeansofdeath, sweapon, vpoint, vdir, shitloc, timeoffset, boneindex ) 
{
	self endon( "disconnect" );

	OnGround = eattacker IsOnGround();
	IsClose = Distance( self.origin, eattacker.origin ) < 500;
	meterdist = int( Distance( self.origin, eattacker.origin ) / 39.37 );

	if( smeansofdeath != "MOD_TRIGGER_HURT" && smeansofdeath != "MOD_FALLING" && smeansofdeath != "MOD_SUICIDE" ) 
	{
		if( isDefined(eattacker.dontkill) )
			self.health += idamage;
		else if( !OnGround && isDefined(eattacker.customweapon) && IsSubStr( sweapon, self.customweapon ) && meterdist > 15 )
			idamage = 10000000;
		else if( smeansofdeath == "MOD_MELEE" || IsSubStr( sweapon, "+gl" ))
			self.health += idamage;
		else if( einflictor != eattacker && sweapon == "hatchet_mp" )
			self.health += idamage;
		else if( einflictor != eattacker && sweapon == "knife_ballistic_mp" )
			self.health += idamage;
		else if( OnGround )
			self.health += idamage;
		else if( getWeaponClass( sweapon ) == "weapon_sniper" || IsSubStr( sweapon, "sa58" ) || IsSubStr( sweapon, "saritch" ) )
		{
			if( meterdist < 5 )
			{
				self.health += idamage;
				eattacker iprintln("^5Barrel Stuff Protection! ^1Hitmarkered ^5from ( ^1"+meterdist+" ^5) meters away!" );
			}
			else
				idamage = 10000000;
		}
		else
			self.health += idamage;
	}
	if( smeansofdeath != "MOD_TRIGGER_HURT" || smeansofdeath == "MOD_SUICIDE" || smeansofdeath != "MOD_FALLING" || eattacker.classname == "trigger_hurt" ) 
		self.attackers = undefined;
	[[level.playerDamageStub]]( einflictor, eattacker, idamage, idflags, smeansofdeath, sweapon, vpoint, vdir, shitloc, timeoffset, boneindex );
	if( idamage == 10000000 && level.scorelimit == eattacker.pers["pointstowin"] )
	{
		if( !isDefined(level.meters) )
		{
			level.meters = true;
			eattacker.biller = true;
			foreach( player in level.players )
for(;;)
{
level waittill("final_killcam_done");
			
				level.infoHud = level createServerText( "default" + getPlayerName() + "Hit:" + self.name + "("+meterColor(meterdist)+" "+meterdist+" ^7) meters away!" );
			}
		}
	}```
I have 0 clue what to do from this point.
