If you go into the construction set, you can find the Item ID for every item in the game, I haven't played in months, so I cannot recall what it would be. Going to
www.gamefaqs.com would give you the correct code to put in, then you just insert the Item ID for what it is you need. There are different formats you need to put it in depending on how to ID is written too, which is why I keep forgetting. The trouble with those formats generally come into play when you go from miscellaneous items to armors and weapons and such.
I do believe though that it would look something like:
player-> AddItem "
Item ID desired" 5
Unfortunately, sometimes if the ID is written a certain way, you need to do without the quotes and use some other method instead but I do believe I only ran into that with weapons.
I hope that helps.
