Hello! I ran into a snag while following the official godot tutorial "Your First Game".
The error code I'm receiving is: Invalid get index 'x' (on base: 'Rect2').


Any Help is greatly appriciated! Thanks! Godot is awesome :D

export var speed = 400
var screen_size

func _ready():
    screen_size = get_viewport_rect()

func _process(delta):

    var velocity = Vector2()

    if Input.is_action_pressed("ui_right"):
        velocity.x += 1
    if Input.is_action_pressed("ui_left"):
        velocity.x -= 1
    if Input.is_action_pressed("ui_down"):
        velocity.y += 1
    if Input.is_action_pressed("ui_up"):
        velocity.y -= 1
    if velocity.length() > 0:
        velocity = velocity.normalized() * speed

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

Best answer

The line in _ready() should be:

screen_size = get_viewport_rect().size

Because you left off size, screen_size is a Rect2, not a Vector2, and thus has no x property.
