Question

When the folder needs creation, I’m trying to make a file with .txt and it gives error code 7. Also, the folder creation gives an error code 31.

Here’s the code:

func Counter_folder():
var dir = DirAccess.open(“user://”)
if !dir:
var error = dir.get_open_error()
print("Failed to open user directory: ", error)
return

var counter = DirAccess.open("user://Counter")
if counter == null:
	var result = dir.make_dir("user://Counter")
	if result:
		print("Created Counter folder.")
		# Initialize counter file
		var counter_file
		counter_file = FileAccess.open("user://Counter/counter.txt", FileAccess.WRITE)
		if !counter_file:
			var error = FileAccess.get_open_error()
			print("Failed to create counter file: ", error)
	elif !result:
		var error = DirAccess.get_open_error()
		print("Failed to create Counter folder: ", error)

func save_world():
var saved_worlds = list_saved_worlds()

if saved_worlds.size() >= 10:
	print("Maximum number of saved worlds reached. Cannot save more.")
	return

var counter = FileAccess.open("user://Counter/counter.txt", FileAccess.READ_WRITE)
if !counter:
	print("Error opening counter file: ", FileAccess.get_open_error())
	return


var world_number = counter.get_line().to_int()
world_number += 1
counter.seek(0)
counter.store_line(str(world_number))
counter.close()

var file_path = "user://Saves/world_" + str(world_number) + ".MW"
print("Saving world to file:", file_path)


var file
file = FileAccess.open(file_path, FileAccess.WRITE)
if !file:
	var error = FileAccess.get_open_error()
	print("Error opening file for saving ", str(error))
	return



for block in get_children():
	if block is StaticBody3D:
		file.store_var(block.transform.origin)

file.close()
print("World saved successfully at ", file_path)

Try using error_string(err) for a more useful message

print("Failed to create Counter folder: ", error_string(error))
3

it gives me invalid parameter

Could you paste the script between three ticks like so

```
type or paste code here
```

And point out which lines give which errors? Like with a comment in the paste?

ticks are on the `~ key, you can use the forum’s </> button or ctrl+e to create the three ticks for you

Y forgot that when it gives error 31 it creates folder and the error
