While dealing with container and inventory items, many developers use a bag/slot couple and set bag to -1 for the case of an inventory item. But a problem occurs when the bank is opened (after BANKFRAME_OPENED event being fired) because the 24 slots of the bank count as a container with -1 as bagID. In the same idea, items in the bank bags can be accessed via container item functions (like GetContainerItemLink(bagID, slotID), PickupContainerItem(bagID, slotID)) with 5 as bagID for the first bank bag, 6 for the second ... until 10 for the sixth.

To sum up, the possibilities for bagID are :

0 for the backpack

1 to 4 for the bags on the character (numbered right to left)

WHILE THE BANK IS OPENED :

-1 for the bank content

5 to 10 for bank bags (numbered left to right)
