Question

Hello. Im having a problem with a gun mechanic in my game. Every time i shoot, the bullet is off by a large amount from where it should be. Any help is appreciated.

Code for gun

extends Node2D

var rot_state = 0
@onready var BULLET = preload("res://Scenes/bullet.tscn")

func check_input():
	if Input.is_action_pressed("Right") and Input.is_action_pressed("Up"):
		rot_state = 1
	elif Input.is_action_pressed("Left") and Input.is_action_pressed("Up"):
		rot_state = 3
	elif Input.is_action_pressed("Right"):
		rot_state = 0
	elif Input.is_action_pressed("Up"):
		rot_state = 2
	elif Input.is_action_pressed("Left"):
		rot_state = 4
	else:
		pass

func rotate_node():
	if rot_state == 0:
		rotation = 0
	elif rot_state == 1:
		rotation = deg_to_rad(-45)
	elif rot_state == 2:
		rotation = deg_to_rad(-90)
	elif rot_state == 3:
		rotation = deg_to_rad(-135)
	elif rot_state == 4:
		rotation = deg_to_rad(-180)

func shoot():
	var b = BULLET.instantiate()
	owner.add_child(b)
	b.transform = $Marker2D.global_transform


func _physics_process(delta):
	check_input()
	rotate_node()
	if Input.is_action_just_pressed("Shoot"):
		shoot()

Code for Bullet

extends Area2D

var speed = 750

# Called every frame. 'delta' is the elapsed time since the previous frame.
func _physics_process(delta):
	global_position += transform.x * speed * delta



func _on_body_entered(body):
	if body.is_in_group("enemy"):
		body.queue_free()
	queue_free()
