У меня в годот вылезла ошибка Assignment is not allowed inside an expression.

extends CharacterBody2D
var state
var max_speed = 200
@onready var anim = $AnimatedSprite2D

func _ready():
pass


func _process(delta):
var movement = movement_vector()
var direction = movement_vector().normalized()
velocity = max_speed * direction
move_and_slide()
if direction != Vector2.ZERO :
$AnimatedSprite2D.play("run")
else:
$AnimatedSprite2D.play("idle")
if Animation == "attack" and get_frame() = 12:
state = false

func movement_vector():
var movement_x = Input.get_action_strength("move_right") - Input.get_action_strength("move_left")
var movement_y = Input.get_action_strength("move_down") - Input.get_action_strength("move_up")
return Vector2(movement_x,movement_y)

func _input(event):
if Input.is _action_pressed("attack"):
play("attack")
state = true
вот ко на всякий случай
