Godot Version

4.3 Stable

Question

So I followed this tutorial for save and load states
here: https://www.youtube.com/watch?v=lXO5Jt957BA

and I was following along with my own script, and I keep getting this error.
Parser Error: Invalid argument for "get_var()" function: argument 1 should be "bool" but is "String".

Heres the code if that helps

var StringVar : String = "DefaultString"
const FileString = "res://SaveFilePath.save"
func save():
	var File = FileAccess.open(FileString, FileAccess.WRITE)
	File.store_var(StringVar)
	File.close()
func Load():
	if FileAccess.file_exists(FileString):
		var File = FileAccess.open(FileString, FileAccess.READ)
		StringVar = File.get_var(StringVar)
		File.close()
	else:print("Theres No Data Here")

How do I fix this?

seems like you passed an argument that is a string inside the get_var() fuction.
Something like this

File.get_var(someString)

It should be removed.

Maybe check your entire script for that or maybe paste it here

Hello Me Again I forgot some parts of the code so I edited it to show what I was dealing with

func Load():
	if FileAccess.file_exists(FileString):
		var File = FileAccess.open(FileString, FileAccess.READ)
		# Right Below this note
		StringVar = File.get_var(StringVar)
		# Right Above This Note
		File.close()
	else:print("Theres No Data Here")

This is exactly where I get this error! from what I gather the get_var() function is supposed to retrieve a variable from the save file, however the function only takes a bool for some other reason. In the tutorial he used multiple integers with the get_var() function like this.

var variable1 = 0
func load():
	FileAccess.file_exist(save_path):
		var File = FileAccess.open(save_path, FileAccess.READ)
		variable1 = File.get_var(variable1)

How can i retrieve the string i saved in the save file?

It should be

StringVar = File.get_var()

Same here

variable1 = File.get_var()

Godot has a built-in function called load so you should rename your function to something else

Thanks for the help! I realized what my issue was so ill log it here for future reference.

I was not setting a value to the string variable!
Therefore I was just saving an empty string, thinking it was broken.

Thanks again for the help!
