Is there any simple way to pass a variable to a function by its name rather than its value?

Question

I am making a simple save system, but i hit a major roadblock when i found out GDScript has no way of fetching the name of a variable. What i’m trying to do is to automate this with a function:

has_met = true
Save._save(“guy”, “has_met”, true)

But wrapping this with a function gets it value instead, writing “false = true” to the file.
Is there any simple way to do this? I have looked into dictionaries but that doesn’t quite seem to be the answer either.

I think dictionaries are absolutely the right way here.

If your goal is to create a save / load system, I think the best option would be to give each instance you want to save / load a function called save() and load() where save returns a dictionary of values you want to save, and load accepts that dictionary back, and re-assigns the variables if the dictionary is not empty.

Then have a piece of code that either finds all instances that implement these functions, or better yet, put all the instances you want to save inside a group.

There’s a nice explanation of how this can be done here:
