#CFItemBroker.py
|
|
#An often used bit of code to add or remove a number of objects
|
|
#Useful for removing items (like in payment or as part of
|
|
#an inventory check) This is also useful for setting the number
|
|
#of a newly created item(s) as it will check for existing item(s) and add
|
|
#the appropriate number of new items avoiding such silliness as the
|
|
#number of the existing items being reset.
|
|
#This will not check for the existence of an item as that would better
|
|
#be done in the calling script so you can be flexible.
