Editing Walking Through Inventory Items

__NOTOC__

'''{{ReqOBSE}}'''

There are two ways to walk an inventory:
#From the end to the beginning - Easier to use with RemoveItem
#From beginning to end

==From the End to the Beginning==
<pre>short invPos
ref pInvObj
ref pCont
...
set pCont to YourDesiredContainer
set invPos to pCont.GetNumItems
While invPos > 0
  set invPos to (invPos - 1)
  set pInvObj to (pCont.GetInventoryObject invPos)
  ;Do whatever you want to do
Loop</pre>

==From the Beginning to the End==
<pre>short InvPos
ref pInvObj
ref pCont
...
set pCont to YourDesiredContainer
set InvPos to 0
Label
set pInvObj to (pCont.GetInventoryObject InvPos)
if pInvObj
  set InvPos to (InvPos + 1)
  ;Do whatever you want to do
  Goto
endif</pre>

==Notes==
*[[GetInventoryObject]] returns the base object FormID. It can't be used when a reference should be used. The information returned about it (i.e., using [[GetSoulLevel]]) will be about the base object and not necessarily each object in the player's inventory. That is, if the player has 2 petty soul gems, one filled and the other empty and you use [[GetSoulLevel]] it will return the same for both (empty).
*Can be used for both [[Container|containers]] and [[:Category:Actors|actors]].
<ul>
<li>Some common things to do with the item</li>
*Run tests such as
 if (IsQuestItem pInvObj)
 if (pInvObj == Apple)
*Find out how many the player has
 set InvObjCount to (pCont.GetItemCount pInvObj)
</ul>
