Set with Arrays

Your decision to use an Array for this purpose was flawed, try using the inner class instead as I suggested in the reply to your other post:

Options, Dictionaries and those pesky strings

Ohh, now I finally get what you mean - the difference between “by val” and “by ref”. But that’s how it works in most programming languages, it’s not only GDScript thing - most primitive variable types are passed by value, not reference. I would suggest that maybe you could make a custom inner class and put an int variable inside. Classes are passed by reference. I would say this solution would be more elegant than using Arrays.

This way you can do you setter and emit the signal when the value of the class variable changes.
