Inventory - Unity Game Development Scripting - page 76

Next, we add the new item to our items list by creating a new KeyValuePair vari-
able and assigning its key to the iterator and its value to NewItem . Finally, we add
the new item's amount by adding it to the itemCount list. This is done by creat-
ing another new KeyValuePair variable. We assign the new KeyValuePair vari-
able's key to the iterator and its value to the val variable.
With this, you now have the capability to add new items to your inventory. When
adding the items, you can add as many as you want. If you want only one of the new
items in the inventory, just set HowMany to 1 , and if you want to remove one, set it to
-1 .
