Just a suggestion since it's annoying to have to re-organize everything. Especially when the backpack is bigger now
Or maybe place it as a block is nice as well

Only way it's happening is if it places a block upon death, which is a nightmare of checks to make it work.

Yes, it can be done. No, I really dont want to do it. Ill leave this open though in case I change my mind

Huh so it's complicated. I thought it's like running whatever the code that you place it down by hand at the death position
But ty for considering it

Technically yes, but what happens if the player suffocates in sand? The backpack would be deleted then, along with all the items.

With the placing by hand, there's a lot more control over it, and I can prevent the player from placing it in a weird place. Otherwise? Not really.

You actually did it O.O

It's not a very great solution. It'll just place it at the nearest empty space along the y axis where the player died, and if there's none, it'll just delete whatever block is at world height.
