FoundryVTT-ItemPiles VS quick-encounters

I created some tokens representing their carriage's cargo compartment and made it interactable with Item Piles. So I can give them access to their stuff when I want them to and just hide it if not.

Esse é o "Item Piles" (https://github.com/fantasycalendar/FoundryVTT-ItemPiles)

FoundryVTT-ItemPiles - Have you ever wished you could represent items in your scenes? A pile of items, something to interact with - or perhaps chests whose appearance changes depending on what happens to it, whether it's open, closed, full, or empty. Do you want an easy way to split loot between players? Do you want easy to use merchants with great UIs?

If that still doesn't resolve it, you can ask about the issue on IronMonk's Discord or put in an issue on the Github page.

I know Item Piles is still in (very) active development. The author definitely intends to port it to v10, but hasn't done so yet.

Item Piles allows you to drop items on the ground, on the canvas. You can create chests (locked or unlocked), and it also allows players to trade with each other.

I would suggest to use the Item Piles to make the chest and use your active tiles config to make the chest visible when they pass the check so you dont need to mess with permissions.

For trading between players I would suggest Item Piles, its main feature is to make npc lootable and easily drag items on the map to make lootable piles but it adds also an usefull trade between players feature
