嗨，这里新人加一。

有没有人跟着官网教程走过？

我之前完全没有编程基础，现在刚入手godot，跟着官网教程走，输入官网代码之后，player根本不动我想知道是哪里出了问题，代码附在下面，请大家指点迷津，谢谢。

extends Area2D

export var speed = 400 # How fast the player will move (pixels/sec).

var screen_size # Size of the game window.

func _ready():

screen_size = get_viewport_rect().size

func _process(delta):

var velocity = Vector2.ZERO # The player's movement vector.

if Input.is_action_pressed("move_right"):

velocity.x += 1

if Input.is_action_pressed("move_left"):

velocity.x -= 1

if Input.is_action_pressed("move_down"):

velocity.y += 1

if Input.is_action_pressed("move_up"):

velocity.y -= 1

if velocity.length() > 0:

velocity = velocity.normalized() * speed

$AnimatedSprite.play()

else:

$AnimatedSprite.stop()

# pass
