Hey I guys I am trying to create a Canon which will always point and shoot towards my player and the canon is successfully always facing him but when I tried this script :

extends Sprite
var player=null

var rot_sped=0.1
var fire_rate=0.5
var fire_time=0.0

var canonbullet=preload("res://CanonBullet.tscn")

func _physics_process(delta):
    if player==null:
        return
    var dir_to_player=player.global_position-global_position
    rotation=dir_to_player.angle()
    fire_time+=delta
    if fire_time>fire_rate:
        fire_time=0
        fire()

func fire():
    print("fire")
    var canonbullet_inst=canonbullet.instance()
    get_tree().get_root().add_child(canonbullet_inst)
    canonbullet_inst.global_position=global_position
    var dir_to_player=(player.global_position-global_position).normalized()
    canonbullet_inst.move_dir=dir_to_player

func set_player(p):
    player=p

I'm getting Invalid set index 'move_dir' (on base: 'KinematicBody2D') with value of type 'Vector2' on

canonbullet_inst.move_dir=dir_to_player

This here is my CanonBullet Script :

extends KinematicBody2D

var move_dir=Vector2()
var move_speed=80

func _physics_process(delta):
    var coll=move_and_collide(move_dir*move_speed*delta)
    if coll:
        if coll.collider.name=="Player":
            print("You Died")
        queue_free()

I fixed it ! My CanonBullet Script wasn't attached :P

So urm... how did you attach it? Same problem here.

I just realized that even though I had this script, it wasn't attached to Cannon Bullet. So I simply just went tot he Cannon Bullet scene. After that I just selected the top node in that scene, did the same step that'll you do to add a script but instead you will have an option of selecting the script you want to add and that was it !
