[_Aion_]

I Want make an system that some players, have "frags to redskull * 2)
i made this in sourcer, but are global... how i made only for some players?

    uint32_t d = g_config.getNumber(ConfigManager::RED_DAILY_LIMIT), w = g_config.getNumber(
        ConfigManager::RED_WEEKLY_LIMIT), m = g_config.getNumber(ConfigManager::RED_MONTHLY_LIMIT);
    if(skull < SKULL_RED && ((d > 0 && tc >= d) || (w > 0 && wc >= w) || (m > 0 && mc >= m)))
        setSkullEnd(now + g_config.getNumber(ConfigManager::RED_SKULL_LENGTH), false, SKULL_RED);
    else if((!g_config.getBool(ConfigManager::FRAG_SYSTEM)) && skull < SKULL_RED * 2 && ((d > 0 && tc >= d) || (w > 0 && wc >= w) || (m > 0 && mc >= m)))
        setSkullEnd(now + g_config.getNumber(ConfigManager::RED_SKULL_LENGTH), false, SKULL_RED); //AION
