Check Items?

Kso. I have this little diddy right here, and my problem is that I have no idea how to do something like this.

Code:
mob
    var
        itemID // item id
        itemAmt // item amount
    proc
        checkItems(itemID, itemAmt)
            /*
                itemID = whatever item thing is.
                itemAmt = whatever item amount is.
            */
            
    // Example in an NPC
    NPC/Kirone
        verb/Talk()
            set src in oview(1)
            usr<<"Hello, [usr]. Do you have the items I want?"
            if(usr.checkItems(1,10)) // if itemID is 1, and itemAmt is 10, could this work?
                usr<<"Yes you do!"
            else
                usr<<"No you don't..."
    item
        Juice
            itemID = 1
            verb/PickUp()
                // How do I make the item amount for THIS item (itemID = 1) go up one?

Loop through your contents, and when you find the item which ID matches, you check the amount.

Something like this:
atom //don't know if you mean mob or obj when you say Items
 var
  itemID
  itemAmt
mob
 proc
  checkItems(itemID, itemAmt)
   for(var/atom/X in contents)
    if(X.itemID!=itemID)continue //these are not the items you're looking for *waves hand*
     if(X.itemAmt>=itemAmt)return 1 //return value of 1
    //returns 0 by default if it doesn't find

I plugged that code right in, tried it out and it didn't work. That's when I realized I was probably too vague, lol.

Okay, so what I need this for is talking to an NPC. I need it to check the itemID and itemAmt for quests and junk like that.

mob/npc/Kirone
 verb/Talk()
  set src in oview(1)
  if(checkItems(1,10))
   return 1
  else
   return 0


Kind of like that, I suppose.

I understood what you meant and my example wasn't plug and play..
mob
 var
  itemID
  itemAmt
 proc
  checkItems(itemID, itemAmt)
   for(var/mob/X in contents)
    if(X.itemID!=itemID)continue //these are not the items you're looking for *waves hand*
    if(X.itemAmt>=itemAmt)return 1 //return value of 1
    //returns 0 by default if it doesn't find
 NPC/Kirone
  verb/Talk()
   set src in oview(1)
   usr<<"Hello, [usr]. Do you have the items I want?"
   if(usr.checkItems(1,10)) //if usr.checkItems() returns a value other than 0 or null do this:
    usr<<"Yes you do!" 
   else //else, do this:
    usr<<"No you don't..."
 item
  Juice //why is juice a mob?
   itemID = 1
   itemAmt=1 //each Juice mob has 1 itemAmt by default
   verb/PickUp()
    set src in oview(1)
    for(var/mob/item/Juice/J in usr.contents)//if it finds a Juice already...
     J.itemAmt+=src.itemAmt //add the amount of the Juice you're about to pick up
     del(src)//code ends here if it finds a Juice in your contents 
    Move(usr) //if there's no Juice in your contents, add it

item/Juice should not be inside of mob right? It should be under obj like so...

obj
  items
    verb
      // All items inherit this ability to pickup
      Pick_Up()
        set src in oview(1)
        if(Move(usr))
          usr << "You picked up [src]!"
    weapons
      melee
        swords
          LongSword
    consumable
      drinks
        Juice
    
mob
  player
  npc
    monster
        troll
    townfolk
        baker


mob is typically reserved for things which are (mob)ile. Is your potion mobile?

There are a ton of examples for how to manage inventory systems in the forums and in the libraries and demo's section.

Sorry for the misunderstanding, I know Juice wasn't a mob, but I was in a hurry so I just added an example without double checking. My bad.

I'll re-test this ASAP.
