hiya. haven't visited the blitz language in a while and trying to dust off the skills.i was trying to write a simple inventory (well, really a shop ) system for a equally simple rpg type game.

i have types set up for various items (potions/swords/armor/etc). something like this:

Type potion
	Field ID%				;id number associated to the potion
	Field name$				;name of the potion
	Field potType%			;type of potion 1=heal,2=buff, etc
	Field value%			;buy/sell value of potion
End Type


then have a type set up for the shop

Type shop
	Field ID%
	Field name$
	Field owner$
	Field potions.potion
	Field armors.armor
	Field swords.sword
	Field sellerGold%
End Type


and here is where my brain is sorta getting fuzzy:

;make a potion
potions.potion=New potion
potions\ID=1234
potions\name="healing elixir"
potions\potType=1
potions\value=20

;make a shop
shops.shop=New shop
shops\ID=4567
shops\name="house of goods"
shops\owner="yo mamma"
....
...
.


pretty much, i'm trying to achieve creating the items and assigning them to the shopkeepers shop. does that make any sense? i suppose the same would be true for a "inventory" system (like what items are being carried on a player, etc. right?

any direction here would be nice,or a codearchive/thread i've missed in my search.

thanks much.

edit: i guess i overlooked this link: http://www.blitzbasic.com/Community/posts.php?topic=41453 i'm guessing this would be the way to do what i'm thinking?

An array is a "Box" to store things in so.......

A List is a "List" of things so .......

Basicly, make potions field of Shop either an array or a list. If you have a small number of shops, with a limeted shelf space, go for an array. If shelf space isnt limeted then list

Note
Maybe you would be better with a "types of Potion Type", then each potion would have a field for typeofpotion

@DQ: If you will need to perform checks against the players inventory you might want to check out --> this. I'm using this system to perform checks against everything the Player can do in my FPSRPG game.


Use the Item's ClassID and ID to point to a specific Custom Type record with more details. A simple Select...Case should do the job easily.

Example:
