I've spawned a new entity like this:

Code:
gentity_t *gf;
gf = G_Spawn();
gf->s.eType = ent->s.eType;
gf->s.modelindex = ent->s.modelindex;
gf->s.modelindex2 = ent->s.modelindex2;
gf->touch = ent->touch;
VectorSet (gf->r.mins, -ITEM_RADIUS, -ITEM_RADIUS, -ITEM_RADIUS);
VectorSet (gf->r.maxs, ITEM_RADIUS, ITEM_RADIUS, ITEM_RADIUS);
gf->item = ent->item;
gf->think = ent->think;
gf->inuse = ent->inuse;
G_SetOrigin( gf, ent->r.currentOrigin );
gf->classname = "team_CTF_ghostflag_red";
gf->item->pickup_name = "Red Ghost Flag";
trap_LinkEntity(gf);


"ent" is either a blue or red ctf flag. There's no problem with spawning this, but when I touch it, NOTHING happens. Touch_Item isn't even CALLED!

Rawing, you need to set gf->r.contents to something like CONTENTS_TRIGGER.

I suppose it also depends on the values in ent (eType, touch, etc.). But is there a reason why you can't use G_SpawnItem()?

Hehe, yeah, well, the reason I didn't use G_SpawnItem() is that I didn't know it =)
But it seems to spawn an item with respawn and such, and I can't set it's origin can I?

Just noticed: Touch_Item isn't called if you got already 100 armor and touch another one. Guess it's something to do with G_CanItemBeGrabbed; I'll take a look at it.

Edit: Stupid me placed the PrintMsg after the CanItemBeGrabbed line =/

Okay, touching the ghost flag works. Other problem now: On death, you don't drop the red-/blueflag but a ghost flag?! TossClientItems:
Code:
if(self->client->ps.powerups[PW_REDFLAG]){
   item = BG_FindItemForPowerup(PW_REDFLAG);
   Drop_Item( self, item, 0);
}

BG_FindItemForPowerup:
Code:
gitem_t   *BG_FindItemForPowerup( powerup_t pw ) {
   int      i;

   for ( i = 0 ; i < bg_numItems ; i++ ) {
      if ( (bg_itemlist[i].giType == IT_POWERUP ||
               bg_itemlist[i].giType == IT_TEAM ||
               bg_itemlist[i].giType == IT_PERSISTANT_POWERUP) &&
         bg_itemlist[i].giTag == pw ) {
         return &bg_itemlist[i];
      }
   }

   return NULL;
}

The ghost flag ain't in bg_itemlist, so why is it dropped!!??!!

Edit: lol posted the code of FindItemForHoldable... corrected that.

I'm not quite sure what you mean. Do you have a screenshot of this 'ghost' flag?

I'll try to explain, coz the ghost flags don't have a model/skin yet...
The ghost flags spawn whenever someone picks up the enemy's flag. It just marks the spot where the flag usually is. Usually, touching your team's flag -if it was dropped- will return it. I changed that, so you pick it up and have to carry it back to the base. So, if you touch the ghost flag and carry your own flag, it's returned and the ghost flag disappears.

Right, after some parsing I get what you mean. Could you post the complete function where the "drop red/blue flag" code lives?

Here it is...
Code:
void TossClientItems( gentity_t *self ) {
   gitem_t      *item;
   int         weapon, ammo;
   int         i, ammopack;
   
   // drop ammo packs
   for(weapon = 2; weapon < MAX_WEAPONS; weapon++){
      item = BG_FindAmmoForWeapon(weapon);
      ammopack = item->quantity;// amount of ammo you get when you pick it up
      for(ammo = self->client->ps.ammo[weapon]; ammo > ammopack; ammo -= ammopack){
         Drop_Item(self, item, 90*crandom());
      }
      Add_Ammo(self, weapon, (ammo - self->client->ps.ammo[weapon]));//set client's ammo
   }

   // drop all weapons
   for (weapon = 1; weapon < MAX_WEAPONS; weapon++ ) {
      if( !(self->client->ps.stats[STAT_WEAPONS] & (1<<weapon)) )
         continue;
      if(weapon==WP_GRENADE_LAUNCHER/*||weapon==WP_LIGHTGRENADE_LAUNCHER*/)
         continue;
   
      // find the item type for this weapon
      item = BG_FindItemForWeapon( weapon );

      // spawn the item
      Drop_Item( self, item, 70*crandom() );
      
      item->quantity = self->client->ps.ammo[weapon];
   }

   // drop all medkits
   item = BG_FindItemForHoldable(HI_MEDKIT);
   for ( i = self->client->ps.stats[STAT_MEDKITS]; i; i-- ) {
      Drop_Item( self, item, i*30*crandom());
   }
   
   // drop flag
   if(self->client->ps.powerups[PW_REDFLAG]){
      item = BG_FindItemForPowerup(PW_REDFLAG);
      Drop_Item( self, item, 0);
   }else if(self->client->ps.powerups[PW_BLUEFLAG]){
      item = BG_FindItemForPowerup(PW_BLUEFLAG);
      Drop_Item( self, item, 0);
   }
}
