Question

Hello, I’m developping a game and for it I need to use a dictionnary. Here’s my issue, I need to find a way to delete an object.

Here’s my dictionnary :

var localDict = {"enigmas" :[
    {
        "answer": "8",
        "fakeAnswer1": "5",
        "fakeAnswer2": "3",
        "fakeAnswer3": "8",
        "question": "question1",
        "solution": "solution1"
    },
    {
        "answer": "10",
        "fakeAnswer1": "8",
        "fakeAnswer2": "4",
        "fakeAnswer3": "2",
        "question": "question2",
        "solution": "solution2"
    }
]
}

My goal is to find a way to delete completely the first object ( without doing it manually ) !
Thanks for any kind of help !

Hello,

You can use Dictionary.erase(key).

More information is available in the godot documentation for Dictionary.

It works, thanks !
but like this :

localDict.enigmas[0].erase("question")
localDict.enigmas[0].erase("answer")
localDict.enigmas[0].erase("fakeAnswer1")
localDict.enigmas[0].erase("fakeAnswer2")
localDict.enigmas[0].erase("fakeAnswer3")
localDict.enigmas[0].erase("solution")

The problem is that when everything is erased, there’s still an empty object.

Console print of LocalDict :

{ "enigmas": [{  }, { "answer": "10", "fakeAnswer1": "8", "fakeAnswer2": "4", "fakeAnswer3": "2", "question": "question2", "solution": "solution2" }

Do you have any idea on how to solve this ?
Thanks

Hello,

Deleting all of the elements in a Dictionary does not delete the dictionary itself. In the context of an Array, you can use Array.remove_at(index) to remove the element in the Array at the specified index. In other contexts, setting the dictionary to null should be sufficient.

If the intention is to remove a dictionary from an array only when the dictionary is empty, this will require you to write some handling code to do so.

func delete_dict_key_or_dict_if_empty(array:Array, index:int, key:String)
    array[index].erase(key)
    if array[index].is_empty():
        array.remove_at(index)

The above was written as example only. Your particular use-case might require different implementation.

Regards,
