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 :smiley:


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
		$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)

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.

Thank you for not only the answer, but the explanation!
