[Bugsy]

I'm not sure how much this will affect server performance, you may see impacts if your csstats.dat file is large. I couldn't test this because I have only bots to work with and they are not ranked in my test configuration.

I used ConnorMcLeod's Spectator Hud Information as a base and made some modifications.

PHP Code:

//Used ConnorMcLeods plugin as base: https://forums.alliedmods.net/showthread.php?p=1469706

#include <amxmodx>
#include <engine>
#include <csx>

new const Version[] = "0.1";

const FirstPersonView = 4;
const Float:fRefreshInterval = 0.25;

new g_HUDSyncObj;

public plugin_init() 
{
    register_plugin( "Spec Rank Info" , Version , "bugsy" );
    
    new iEntity = create_entity( "info_target" );
    entity_set_string( iEntity , EV_SZ_classname , "SpecHUDEntity" );
    register_think( "SpecHUDEntity" , "SpecHUDThink" );
    entity_set_float( iEntity , EV_FL_nextthink , get_gametime() + fRefreshInterval );
    
    g_HUDSyncObj = CreateHudSyncObj();
}

public SpecHUDThink( iEntity )
{
    new iAlivePlayers[ 32 ] , iDeadPlayers[ 32 ] , iAliveNum , iDeadNum , iAlivePlayer , iDeadPlayer;
    new iRank , iStats[ 8 ] , iBodyHits[ 8 ] , szName[ 32 ] , bool:bRetrievedData;
    
    entity_set_float( iEntity , EV_FL_nextthink , get_gametime() + fRefreshInterval );
    
    get_players( iAlivePlayers , iAliveNum , "a" );
    
    if( !iAliveNum )
        return
    
    get_players( iDeadPlayers , iDeadNum , "bch" );
    
    if( !iDeadNum )
        return    
    
    for ( new iAlive = 0 ; iAlive < iAliveNum ; iAlive++ )
    {
        iAlivePlayer = iAlivePlayers[ iAlive ];
        
        bRetrievedData = false;
        
        for( new iDead = 0 ; iDead < iDeadNum ; iDead++ )
        {
            iDeadPlayer = iDeadPlayers[ iDead ];
            
            if ( entity_get_int( iDeadPlayer , EV_INT_iuser2 ) == iAlivePlayer && entity_get_int( iDeadPlayer , EV_INT_iuser1 ) == FirstPersonView )
            {
                if ( bRetrievedData == false )
                {
                    get_user_name( iAlivePlayer , szName , charsmax( szName ) );
                    iRank = get_user_stats( iAlivePlayer , iStats , iBodyHits );
                    bRetrievedData = true;
                }
                
                ClearSyncHud( iDeadPlayer , g_HUDSyncObj );
                set_hudmessage( 255 , 255 , 255 , -1.0 , 0.25 , .holdtime=0.5 , .channel=-1 );
                ShowSyncHudMsg( iDeadPlayer , g_HUDSyncObj , "%s^nRank: %d^nKills: %d^nDeaths: %d" , szName , iRank , iStats[ 0 ] , iStats[ 1 ] );
