It looks like here you’re setting a speed variable but never actually using it. Try adding a move_and_slide function and pass in speed.
Two grammar mistakes; isactionpressed should be is_action_pressed, and uiright should be ui_right.
You should also replace getinput() with _process(_delta) as there is no such function, and if you meant for it to be a custom function, there is no code that calls it.
I believe that this would be the proper code:
export (int) var v_walk = 100
var speed = Vector2()
func _process(_delta):
speed.x = 0
var right = Input.is_action_pressed('ui_right')
var left = Input.is_action_pressed("ui_left")
if right:
speed.x += v_walk
$AnimatedSprite.flip_h = speed.x < 0
$AnimatedSprite.animation = "Walk"
elif left:
speed.x -= v_walk
$AnimatedSprite.flip_h = speed.x < 0
$AnimatedSprite.animation = "Walk"
else:
$AnimatedSprite.animation = "Idle"
func _physics_process(_delta):
move_and_slide(speed)
