I saw the word 'useless' in the function prototype. Check it out. Falling damage is worldspawn. Crossbow will show as bolt, etc. Gauss will always be a client index. Just supplying some useless information. Haven't tested your work yet. Maybe add a vote to enable disable your plugin since if one cannot wallbang that spoils the fun factor by and large.

    RegisterHam(Ham_TakeDamage, "player", "Event_Damage", 1);
}

public Event_Damage(victim, inflictor, attacker, Float:damage, damagebits)
{
    static szClass[MAX_NAME_LENGTH];

    pev(inflictor, pev_classname, szClass, charsmax(szClass))
    client_print 0, print_center, "%s", szClass
}
