So I watched heartbeats tutorials and his inventory is beautiful but I do want to add a chest and put items in it from the inventory,
I'm not a beginner but not good either I did write some codes on my own but yeah still getting there
So my question is, how do I do that?
Sorry for my dumb question

I haven't really gone through it, but this one is for godot4, not godot 3, and it shows how to drop items, so it's pretty close to what you want. You just have to drop the item into a chest.

    Thank you, I'll check that out and see if it works!
    But I'm using Godot 3 so yeah that might be an issue

      Yeah no I just used it, it is full of codes and mine is just simple, not even stackable, it's dragging and dropping.

        Something I'm trying to advocate for especially for people who don't want to spend a million years coding a complex inventory system they're barely going to use is the concept of using lists rather than grids for your inventories and this will work with a chest setup too. You simply make an array and add your items to the array to keep track of everything, the UI works way easier than a grid setup because you just need a scrollbar much like how it works in bethesda type games and there you go you've got an almost infinite inventory available with little effort. To transfer things to different inventories you've just got to delete the child sprites associated with the scrollbar then add them to the other scrollbar while updating your arrays accordingly. I've confirmed this works with my own code testing it and I'm honestly surprised more devs don't opt for a list based inventory because it's so much easier to code and design, they all seem obsessed with drag and drop grids.
