Im stucked in this part of "Dogde The creeps"

Question

When I try to move my player an error shows that says this "Invalid operands in Vector 2 and string in operator '*' ". I marked the sentence where the error is. I don't know what to do.

extends Area2D

export var speed = '400'
var screen_size

func ready():
screensize = getviewportrect().size

func process(delta):
var velocity = Vector2()
if Input.isactionpressed ("uiright"):
velocity.x += 1
if Input.isactionpressed ("uileft"):
velocity.x -= 1
if Input.isactionpressed("uiup"):
velocity.y -= 1
if Input.isactionpressed("ui_down"):
velocity.y += 1
if velocity.length() > 0:
***velocity = velocity.normalized() * speed***
$AnimatedSprite.play()
else:
$AnimatedSprite.stop()

position += velocity * delta
position.x = clamp(position.x, 0, screen_size.x)
position.y = clamp(position.y, 0, screen_size.y)

Answer 1

Because you set speed = '400' you've made speed be a String, not a number. Remove the quote marks.

Thanks, now it works
