I’m writing a method (function to read from a file), and I get this error: Could not find type “File” in the current scope and Identifier “File” not declared in the current scope.

Here is the code :

func loads(num: int) → void:

var poemTitle: RichTextLabel = $Title
var poemText: RichTextLabel = $Text

var txtFile: File = File.new()
if !txtFile.file_exists("res://Poems/" + story[iStory] + ".txt"):
	poemText.text = "Story not found"
	return

txtFile.open("res://Poems/" + story[iStory] + ".txt", File.READ)

I don’t think there’s any such class. I think you probably want the FileAccess class instead.

Thank you, I needed this!

Right. The File class from Godot 3.x was replaced by the FileAccess class in Godot 4.x.

Related, for this (and other) upgrade 3.x to 4.x topics, see this docs page:

I get this error: Native class “FileAccess” cannot be constructed as it is abstract., Static function “new()” not found in base “FileAccess”.

Here is the code below:

var poemTitle = get_node("Title") as RichTextLabel
var poemText = get_node("Text") as RichTextLabel

var txtFile: FileAccess = FileAccess.new()

if !txtFile.file_exists("res://Poems/" + story[iStory] + ".txt"):
	poemText.text = "Story not found"
	return

txtFile.open("res://Poems/" + story[iStory] + ".txt", FileAccess.READ)

Check the docs linked above by @HyperlinkYourHeart. It contains some very simple examples of a file read operation…

Okay, I will do so. Thank you so much for the help.
