我本来想做一个角色移动，代码：
extends Area2D
@export var speed = 300
var screen_size
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("right"):
velocity.x += 1
if Input.is_action_pressed("left"):
velocity.x -= 1
if Input.is_action_pressed("down"):
velocity.y += 1
if Input.is_action_pressed("up"):
velocity.y -= 1
if velocity.length() > 0:
velocity = velocity.normalized() * speed
$AnimatedSprite2D.play()
else:
$AnimatedSprite2D.stop()
position += velocity * delta
position = position.clamp(Vector2.ZERO, screen_size)
但是不知道为啥，它总是不能很好的移动，每次都是上下左右会在某一个地方卡住，按键过不去
