Getting the name of the variable as a string in GD Script

Question

I have been looking for a solution everywhere on the internet but nowhere I can see a single script which lets me read the name of a variable as a string in Godot 3.1

What I want to do:

1. Save path names as variables.
2. Compare the name of the path variable as a string to the value of another string and print the path value.

Eg -

var Apple = "mypath/folder/apple.png"
var myArray = ["Apple", "Pear"]

Function that compares the Variable name as String to the String -

if (myArray[myposition] == **the required function that outputs variable name as String**(Apple) :
       print (Apple)  #this prints out the path.

Thanks in advance!

I think your approach here might be a little oversimplified for what you're trying to accomplish. It basically seems to work out to if (array[apple]) == apple then apple, which doesn't really solve a programmatic problem. More complexity seems required.

First, you might have a function to return all of your icon names, something like this.

func get_avatar_names():
    var avatar_names = []
    var folder_path = "res://my/path"
    var avatar_dir = Directory.new()
    avatar_dir.open(folder_path)
    avatar_dir.list_dir_begin(true, true)
    while true:
        var avatar_file = avatar_dir.get_next()
        if avatar_file == "":
            break
        else:
            var avatar_name = avatar_file.trim_suffix(".png")
            avatar_names.append(avatar_name)
    return avatar_names

Then something like this back in the main function, where you have your list of names you care about at the moment, and for each name, check the list of avatar names, and if you have a match, reconstruct the path and do other work:

var some_names = ["Jim","Apple","Sally"]
var avatar_names = get_avatar_names()
for name in some_names:
    if avatar_names.has(name):
        var img_path = "res://my/path/" + name + ".png"
        # load images, additional work, etc...

That's the approach I would take here, hope this makes sense and helps.
