is there a way to save all items in a player's inventory with dynamic properties?

[lime pecan]

No, if you save it in an object that will save it as an object but there is no way to permanently save that object, if you want to save an inventory you need to copy it over to another inventory

[tidal cosmos]

accualy im pretty sure its possible

maybe not with dynamic properties cus idk how that works

but you could with tags atlest

or maybe entity properties

[whole laurel]

Only the basic item data

Like enchantments, durability, name, lore, etc

There is no way to get the "data" value you use for commands

[tidal cosmos]

like durability?

[whole laurel]

Data value only affects tool durability in commands

But for other items, it represents variations

[tidal cosmos]

does scripts not check that?

[whole laurel]

Like sand and red sand

[whole laurel]

You can copy the ItemStack instance and it will keep all the data, but there is no way to save it in a db

[tidal cosmos]

doesnt lore help with that?

[whole laurel]

Lore is only the text you see below the name

[tidal cosmos]

Lore doesnt check the items name?

dam that accualy sucks

[whole laurel]

Lets go from the start, you can get the item, get the components, enchantments, nametag, lore, amount

But not the data value

If you want to keep the item completely the same, you need to save it in another container so you can just transfer them again later

That container can be a chest or a entity with the inventory component

[tidal cosmos]

and you cannot tranfer objects to dynamic properties / or entity properties

[whole laurel]

You can if you stringify an object with that obtained data

But as I said, there is no way to get the "data value"

So lets say you have different anvils in your inventory

A normal one and broken one

In the script there is no way to differentiate one and another

You would have to serialize all the available item data first
