Lesson 9: Creating the player projectile

Hey, In my projectile script when I move it with the move_and_collide() method it keeps throwing errors.

E 0:00:00:0488   _physics_process: Move functions do not work together with 'sync to physics' option. Please read the documentation.
  <C++ Source>   scene/2d/physics_body_2d.cpp:79 @ move_and_collide()
  <Stack Trace>  projectile.gd:20 @ _physics_process()

Weirdly the hit animation for the projectile was unused, when the collision happens it just removes the node.

Here is my complete projectile script, it look a little awkward (something could be done to have it “stuck” position-wise to whatever it collided, but in this case I deemed it good enough):

extends AnimatableBody2D

var death_time = 0

const PROJECTILE_SPEED = 1000

@onready var sprite = $AnimatedSprite2D

# Called when the node enters the scene tree for the first time.
func _ready():
	death_time = Time.get_ticks_msec() + 2000


# Called every frame. 'delta' is the elapsed time since the previous frame.
func _process(delta):
	if(Time.get_ticks_msec() > death_time):
		queue_free()

func _physics_process(delta):
	# if we are on the hit animation there is no need to move it further
	if (sprite.animation == "hit"):
		return
		
	var distance = Vector2.RIGHT * PROJECTILE_SPEED * delta
	var collision = move_and_collide(distance)
	if collision:
		sprite.play("hit")
		sprite.animation_finished.connect(_on_animation_finished)
		
		if(collision.get_collider().is_in_group("enemy")):
			collision.get_collider().die()

func _on_animation_finished():
	queue_free()
