I trying to save my scene

just like this…

export var saveScene: String = “”
var file = File.new()

func _on_save_btn_button_up():
save_data()

func save_data():
file.open(“res://Save/save.text”, File.WRITE)
file.store_string(saveScene)
file.close()

but i got this error message “File must be opened before use” in windows

Try moving the File.new() assignment inside the save_data() function?

I tried to put the

file = file.new()
inside save_data() function

but got the same result…

Oh right, res:// is inaccessible during runtime. You can’t open files in it when you run the program. Try saving files in the user:// directory instead.

I encountered this error when I forgot to call file.Close() when initially reading/loading data in _Ready(). Later, when I tried to save and write to the file, the error was thrown.
