Customising the Shop

The admin GUI shop is dynamically populated by /config/mmoecon/MMOShop.json.
If you don't want to write a shop JSON file from scratch, an example one will be generated the first time the mod runs to get you started.

Example MMOShop.JSON

The shop will support any modded items supported by the server its running on.
