hello, So i am trying to access the "cost" and "wear" to use the values but don't really know how to.

This is the dictionary:

var shop_items = {
"Engine": {
"Ignition Coils":{"cost":30, "wear":0},
"Spark Plugs":{"cost":40, "wear":0}
"Brakes": {
"Brake Pads":{"cost":50, "wear":0},
"Brake Discs":{"cost":70, "wear":0},
"Cylinder":{"cost":30, "wear":0}

i tried with this in a for loop but it returns null:


If somebody can tell me how to get the cost and wear values, i will really appreciate. Thank you

The way I like to access stuff from dictionaries is like this

This will return the 30 in your code.

I think get() on a Dictionary is only more useful in some cases because it returns null rather than throwing an error if a key is missing. In my opinion I'd rather have an error thrown if my Dictionary isn't setup right or isn't being accessed right.

Here is an example how you can work with Dictionaries and how you can iterate over one.

func _ready() -> void:
    # get values
    print(shop_items["Engine"]["Ignition Coils"]["cost"])
    # Iterate 
    for items in shop_items:
        print(items, shop_items[items])
        for part_func in shop_items[items]:
            for properties in shop_items[items][part_func]:
                print(properties, " ", shop_items[items][part_func][properties])
