|
|
#An often used bit of code to add or remove a number of objects |
| 3 |
|
|
#Useful for removing items (like in payment or as part of |
| 4 |
|
|
#an inventory check) This is also useful for setting the number |
| 5 |
|
|
#of a newly created item(s) as it will check for existing item(s) and add |
| 6 |
|
|
#the appropriate number of new items avoiding such silliness as the |
| 7 |
|
|
#number of the existing items being reset. |
| 8 |
|
|
#This will not check for the existence of an item as that would better |
| 9 |
|
|
#be done in the calling script so you can be flexible. |
