I want trade to be more active by objects to be a trade.

Barter floor is Building that can buy and sell objects that can be carried and put in.
Its use is similar to a barter stand.
Its size is 3x3(2.5x2.5), and construction materials also include stones, wood, clothes and metals.
The objects that are stored are stacked on the barter floor by overlapping the green hand and the red hand.
When buy, lift up the object and interact with the barter floor by turning on the flower.
Its implementation prerequisites must be able to display the quantity, quality, classification of the objects by 'inspect', and also be able to identify this on the trade screen.
This can be traded between objects and items (coins, etc.).
If possible, live animals tied to a hitching post should also be able to implement the trade in this.
