How to work with the wrapped arrays?

[luiscesjr]

I'm not a pro developer by any means, so I'm confused on how to work with the wrapped returns from the system.

For example, I'm having an issue right now with one of my recipes, it's setup correctly to receive 1 item as input and output another 2 itens, and despite all being right, still a check of "craft_station.can_craft(recipe)" gives out false.

And if I try to print my way and find out what's happening, I usually get [Wrapped:0] for trying print(recipe). Now I can for example, after looking around for some time, try print(recipe.ingredients), which gives me another [Wrapped:0], and print(recipe.ingredients[0]) that also prints [Wrapped:0].

So how can I work with this? Is it because it's a wrapped C++ object and godot does not expose it to GDscript? I'm not asking this to criticize, I'm really eager to learn. Also would be nice in the docs to somehow have all the options these arrays/dictionaries have buried within them to facilitate navigation codewise.

hi @luiscesjr!
Wrapped is an encapsulated resource that does not mean that the path is certain but when printing the ingredient or product you use or id not be able to do so:

print(recipe.ingredients[0].item_id)

Trying in craftstation tutorial for this:

inventory-system/addons/inventory-system-demos/tutorials/tutorial_craft_station_01/tutorial_craft_station_01.gd

Lines 21 to 27 in 915e3f9

	var count = 0
	for recipe_index in craft_station.valid_recipes:
	var recipe = craft_station.database.recipes[recipe_index]
	print(recipe.products[0].item_id)
	count += 1

Only by increasing your ability to print the resource path through the resources of the sao resources system located within the resource database (for convenience and ease)

Huuum I think I got it. Just went on a rabbit hole learning more about encapsulation, that was very insightful! Thank you. I made my whole UI from the ground up, so I'm extracting more and more data from the addon to personalize it to my needs.
