CS-style weapon dropping

Editor: New code in RED Old code in YELLOW
Here is a little tutorial on CS-style weapon dropping. Well... not really like in CS, 
this one will only drop the ammo in the clip, not all ammo for that weapon. 

Goto PlayerDeathThink in CBasePlayer (player.cpp), then find this:

    if ( HasWeapons() )
    {
        etc etc
    }

Change it to this:

    if ( HasWeapons() )
    {
        DropPlayerItem(""); // drop the weapon that the player is using
        RemoveAllItems(true); // Remove every thing else including the HEV
    }

Now, open DropPlayerItem in the same file and goto this stuff:

        if ( pWeapon )
        {
            blah blah
        }

Remove all the blah blah-stuff and add this:

        if ( pWeapon )
        {
    // Don't drop the melee weapon. You need do replace "weapon_knife" with your melee weapon...
            if ((char *)STRING(pWeapon->pev->classname)=="weapon_knife")
                return;

            g_pGameRules->GetNextBestWeapon( this, pWeapon );
            UTIL_MakeVectors ( pev->angles ); 
            pev->weapons &= ~(1<< pWeapon->m_iId);// take item off hud
            
    // Create a new weapon and toss it away
            CBaseEntity *pItem = CBaseEntity::Create((char *)STRING(pWeapon->pev->classname), 
				pev->origin + gpGlobals->v_forward * 10, pev->angles, edict() );
            pItem->pev->velocity = gpGlobals->v_forward * RANDOM_LONG(150,300) + 
				gpGlobals->v_forward * RANDOM_LONG(80,110);
            pItem->pev->spawnflags |= SF_NORESPAWN; // don't respawn

            // Convect our weapons (they are CBasePlayerItems) to CBasePlayerWeapons
            CBasePlayerWeapon *weap = (CBasePlayerWeapon *)pItem; // the new weapon
            CBasePlayerWeapon *OldWeap = (CBasePlayerWeapon *)pWeapon; // the old weapon
            int AmmoLeftInClip;

    // if the weapon doesn't have any clip then save all ammo in the new weapon, 
	// else just save the ammo in the clip
            if (OldWeap->iMaxClip()==WEAPON_NOCLIP)
            {
                AmmoLeftInClip = m_rgAmmo[OldWeap->m_iPrimaryAmmoType];
                weap->m_iDefaultAmmo = AmmoLeftInClip;
            }
            else
            {
                AmmoLeftInClip = OldWeap->m_iClip;
                weap->m_iClip = AmmoLeftInClip;
                weap->m_iDefaultAmmo = 0;
            }

            RemovePlayerItem(pWeapon);

            return;

    }

Surreals code:

In weapons.cpp go to the function PackWeapon and right before the code... 
 
 pWeapon->pev->spawnflags |= SF_NORESPAWN;// never respawn
 pWeapon->pev->movetype = MOVETYPE_NONE;
 pWeapon->pev->solid = SOLID_NOT;
 pWeapon->pev->effects = EF_NODRAW;
 pWeapon->pev->modelindex = 0;
 pWeapon->pev->model = iStringNull;
 pWeapon->pev->owner = edict();
 pWeapon->SetThink( NULL );// crowbar may be trying to swing again, etc.
 pWeapon->SetTouch( NULL );
 pWeapon->m_pPlayer = NULL;
 
plug this chunk o code in....
 
  // the "real" thing"
  if ((!strcmp((char *)STRING( pWeapon->pev->classname ), "weapon_crowbar")))
   SET_MODEL( ENT(pev), "models/w_crowbar.mdl");
  else if ((!strcmp((char *)STRING( pWeapon->pev->classname ), "weapon_9mmhandgun")))
   SET_MODEL( ENT(pev), "models/w_9mmhandgun.mdl");
  else if ((!strcmp((char *)STRING( pWeapon->pev->classname ), "weapon_357")))
   SET_MODEL( ENT(pev), "models/w_357.mdl");
  else if ((!strcmp((char *)STRING( pWeapon->pev->classname ), "weapon_shotgun")))
   SET_MODEL( ENT(pev), "models/w_shotgun.mdl");
  else if ((!strcmp((char *)STRING( pWeapon->pev->classname ), "weapon_9mmAR")))
   SET_MODEL( ENT(pev), "models/w_9mmar.mdl");
  else if ((!strcmp((char *)STRING( pWeapon->pev->classname ), "weapon_crossbow")))
   SET_MODEL( ENT(pev), "models/w_crossbow.mdl");
  else if ((!strcmp((char *)STRING( pWeapon->pev->classname ), "weapon_rpg")))
   SET_MODEL( ENT(pev), "models/w_rpg.mdl");
  else if ((!strcmp((char *)STRING( pWeapon->pev->classname ), "weapon_gauss")))
   SET_MODEL( ENT(pev), "models/w_gauss.mdl");
  else if ((!strcmp((char *)STRING( pWeapon->pev->classname ), "weapon_hornetgun")))
   SET_MODEL( ENT(pev), "models/w_hgun.mdl");
  else if ((!strcmp((char *)STRING( pWeapon->pev->classname ), "weapon_egon")))
   SET_MODEL( ENT(pev), "models/w_egon.mdl");
  else if ((!strcmp((char *)STRING( pWeapon->pev->classname ), "weapon_snark")))
   SET_MODEL( ENT(pev), "models/w_squeak.mdl");
  else if ((!strcmp((char *)STRING( pWeapon->pev->classname ), "weapon_tripmine")))
  {
   pev->body = 3;
   pev->sequence = 8;
   pev->absmin = pev->origin + Vector(-16, -16, -5);
   pev->absmax = pev->origin + Vector(16, 16, 28); 
   SET_MODEL( ENT(pev), "models/v_tripmine.mdl");
  }
  else if ((!strcmp((char *)STRING( pWeapon->pev->classname ), "weapon_handgrenade")))
   SET_MODEL( ENT(pev), "models/w_grenade.mdl");
  else if ((!strcmp((char *)STRING( pWeapon->pev->classname ), "weapon_satchel")))
   SET_MODEL( ENT(pev), "models/w_satchel.mdl");
 }

There is a easier way to do this... use a sprintf function and store the classname of that current weapon then SET_MODEL to that array. (add 7 to chop off the weapon_ class) Its a hell of alot smaller (about 3 lines of code...) but there is a bug in it... the model flickers on and off... (cant convert const chars into *chars... blah blah blah..)
