GetNumItems

A command for Oblivion Script Extender

Syntax:

GetNumItems

Must be called on a reference. Returns the number of unique items in the object's inventory.

Notes

• Note that it is the number of unique items in the inventory - 10 arrows will only count as one item.
• Gold counts as an item, so if you have any gold, you'll get a +1 to your return
• Equipped items and identical items that are unequipped are still only one unique item
• Using this function every frame will significantly drop FPS. The more items that have to be scanned, the worse it is (i.e., 1 item a frame will drop it by 3, 15 by 25). Use this function only when necessary, and try to avoid using it in GameMode.
  • There are several ways to use GetInventoryObject instead of GetNumItems (keep in mind that it is also CPU-heavy, but not as much).
    

If you need to test if a container has items in it, use

ref pInvObj
...
set pInvObj to (SomeContainer.GetInventoryObject 0)
if pInvObj
...

If you need to see if the player has a new item, use GetNumItems once and then GetInventoryObject

ref pInvObj
short InvTotal
...
if (InvTotal == 0)
  set InvTotal to SomeContainer.GetNumItems
else
  set pInvObj (SomeContainer.GetInventoryObject InvTotal)
  if pInvObj
...
