I started to learn Godot and GDScript for two days and I have a problem with the first game tutorial on the Godot website. My player isn't moving and I don't know what the mistake is.
Here is my code:
export var speed = 400 # How fast the player will move (pixels/sec).
var screen_size # Size of the game window.
screensize = getviewport_rect().size
var velocity = Vector2() # The player's movement vector
velocity.x += 1
velocity.x -= 1
velocity.y += 1
velocity.y -= 1
if velocity.length() > 0:
velocity = velocity.normalized() * speed
position += velocity * delta
position.x = clamp(position.x, 0, screensize.x)
position.y = clamp(position.y, 0, screen_size.y)
I don't copy & paste it from the website. I've got an error which says 'Invalid get index 'x' (on base: 'Nil'). What does ist mean?
