Here is the code(Not all the code, just the relevant parts):

func _ready():
	savex(position.x)
	savey(position.y)
	
func savex(content):
	var file = File.new()
	file.open("user://pos_x.dat", file.WRITE)
	file.store_line(str(content))
	file.close()
func savey(content):
	var file = File.new()
	file.open("user://pos_y.dat", file.WRITE)
	file.store_line(str(content))
	file.close()

func loadx():
	var file = File.new()
	file.open("user://pos_x.dat", file.READ)
	var content = file.get_line()
	file.close()
	print(content)
	position.x = content

	var file = File.new()
	file.open("user://pos_y.dat", file.READ)
	var content = file.get_line()

	# print("COLL")

I assume the problem is here:

position.x = content

That’s because you loaded the value into content via file.get_line(), which is documented to return a string.

And, since the x component of a Vector2 is of type float, you can’t set it to a string value.

Assuming the string value you’ve loaded into content can be converted to a float, one fix would be:

position.x = float(content)

Thank you so much! :slight_smile: That was dumb of me.

Hey guys,

I’m having the same error with Godot 4 and I’m scratching my head.

func _physics_process(_delta):
	motion.x = Input.get_action_strength("right") - Input.get_action_strength("left")

Where motion is a Vector2(). I double-check the input names and they are well written.

What am I missing?

If you do have the same error, that implies that motion is NOT a Vector2 - at least at the time the error is generated. With that in mind, I don’t think the problem is in the above code It’s likely somewhere else, where motion is (inadvertently) assigned a String value.
