"Buy Only" in Shops

I'm working on a system in my game that has several variables that can be spent as money. In RM2K and 2K3, there was a "Buy Only" option for shops, which I really need, but its not there anymore. How would I go about preventing selling for certain shops?

here you go:

Made by Sandgolem at gamebaker.com

This script allows you to prevent shops from buying types of items, or only buying certain items of a type. Can be mixed, you can make one shop that will only buy armors #1-10 and no items/weapons for example. Each shop can have their own settings, with no script editing required.

Simply put it in your game, no assembly required.

To keep a shop from buying certain types of items, use these in a call script right before the shop processing:
$sg_doesntbuy_item = true
$sg_doesntbuy_armor = true
$sg_doesntbuy_weapon = true
To have a shop buy only certain items from that set, use these (not the one for that type above):
$sg_onlybuys_item = [#,#]
$sg_onlybuys_armor = [#,#]
$sg_onlybuys_weapon = [#,#]
Those are arrays, use [#,#,#] and [#,#,#,#,#] to add more items to the list. Replace the #s with the item #'s from the database. Make sure you disable the other types of items from being sold if you want the shop to only buy those items.

You can mix and match them however you want. All of these settings are automatically removed after the shop has been called.

I thought he said Rm2k3
That doesnt support scripts..

Thank you! I was going to go crazy if I had to work around it. It's doable, but it would cost me hours of work.

Nope. I said that they had the option built into the editor in RM2K3. I'm using XP.

no problem, glad I could help
