Weird type behaviour with Vector3

[Smorty100]

I use this plugin to save some positions. Currently I do it like this:

SaveSystem.set_var(G.temp["SCENE_NAME"] + "_CHECKPOINT", %Spawn.global_position)
SaveSystem.save()
print("Type of position is " + str(typeof(%Spawn.global_position)) + " but saved type is " + str(typeof(SaveSystem.get_var(G.temp["SCENE_NAME"] + "_CHECKPOINT"))))

That last line is to check if the saved position and the actual position are of the same type, and they are! They are both a 9, which is a Vector3.
BUT! When I try to access that value after closing and opening the game, it gives me a String! It's a string with the Vector3 inside of it, kinda like this:
var savedPosition:String = "(4.43, 345.534, 543234.5453)"
Now that is some really weird behaviour, and will require some workarounds to get it working as intended...

Hello! That is because there is no easy and convenient way (as far as I know) to keep track of types inside a save file, considering they are all turned into text data at the end of the day. I've been considering type support to a certain extent, though - or function calls that specifically typecast the retrieved data.
As a workaround, you can always do a typecast from string to Vector3 to retrieve the vector, this is how it's done with both Vector2 and Vector3:
var position = str2var("Vector3" + SaveSystem.get_var(G.temp["SCENE_NAME"] + "_CHECKPOINT"))
This will give you Vector3(4.43, 345.534, 543234.5453) as the parameter of str2var, which Godot can convert.

Edit: I just noticed this is the Godot 3 repo, in which case, you have str2var. str_to_var is for Godot 4. :)
