We wanted to have a store system with the pop up dialogue device in which when you press a button, it grants you an item while taking gold from your inventory. Unfortunately you cant do what we want to do with the item spawner, which does have a gold cost system. I think gold cost or material cost for item granters could add to the pop up dialogue and hud systems in creative maps.
Thank you for your feedback. While I cannot guarantee a response, I can confirm that this has been forwarded to the appropriate team.
