This script allows you to create a shop that only allows the player to sell things
to the shop.
You can setup your shop to only take specific items, and you can set up the sell
prices of any item.
Place this script below the Shop Manager.
In the interpreter, before the “Shop Processing” command, make a script call
@shop_type = "SellOnlyShop"
In your shop processing editor, you can choose which items you want to be able to sell, and the sell prices. If you don’t need item filtering, just check the “purchase only” box and the player can sell almost anything they want.
