Stupid question here, i know…
So… I made a top-down character which can move north, south, east and west. I want him to be able to shoot bullets in those directions. I instanced the bullet, made a simple script so the bullet goes in the direction the player faced last time. The problem is, if i move the player, it’s direction changes… the bullet’s direction changes too
(i’ve been thinking of a solution to this problem for almost 2 days… lack of exercises)
I thought of storing in a variable the direction the player faced when the bullet was shot. How can I do that?
The bullet’s movement

 motion.y = -1 * BULLET_SPEED
set_position(get_position()+motion * delta)

This is for the north direction. Basically I checked the player’s direction and with an If, I would multiply the motion’s x or y with -1 or 1 depending on the direction
I know, this is the most stupid way to do it… i’ve tried others but I was unsuccesful
Is there a better solution?

I guess you added a bullet instance under the player node.
you should add the bullet node outside of player node.

can you add more code? perhaps having full script of player and bullet would let us help you a little more.

You surely added bullet as child of player. Instead you should do something like this (add to root node):

func _fire():
    var bullet = preload("res://Bullets/EnergyShot.tscn").instance()

I always use that code.

No, the bullet is the child of the main node. I used get_tree().call_deferred("add_child, bullet)
Still, if I move the player (which means changing it’s direction) the bullet changes direction too

And have you tried the way i wrote? Im using that in my current develpoment and works. If not, can you share some code or even the entire project?

Fixed it… finally… it was so so easy :stuck_out_tongue:

You should add it as an answer and select it so others see its solved!

It was so damn easy… i made a function set_new_position(dir) on the bullet. Then I called it when the bullet was instanced

bullet = bulletscene.instance()
get_tree().call_deferred("add_child", bullet)

Then I used the dir parameter to establish the bullet’s direction
