Sprite Trail with Particle FX and its rotation

Questions
1

Hi,
I created a sword that will spawn from many angles and fly across the screen.
The Sword should have like a Trail, which i use Particle FX for it. Not sure if this is the right approach to it since the train will look like the sword (same Sprite). It looks kinda ok.

Now I can rotate the sprite but not the Emitter itself. so the direction of the Trail will always look the same no matter the rotation of the Sword.

I did read that i should put the emitter in a game object and rotate that, but the sword trail will still look like this:

facing upwards no matter the direction and rotation of the gameobject is going.

How can i rotate the Trail so it has the same direction as the Sprite?

function init(self)
	local emitter_id = go.get_id("sasaki_katana_emitter")
	local rotation_self = go.get_rotation(".")
	-- set the rotation of the emitter game object
	go.set_rotation(rotation_self, emitter_id)

	particlefx.play("sasaki_katana_emitter#sasaki_katana")
	go.animate(".", "position", go.PLAYBACK_ONCE_FORWARD, vmath.vector3(1000,1000,0), go.EASING_LINEAR, 10)
end

and this is how the collection looks like i create from the collection_factory:

I used to have a normal factory but I tried to go with the approach to rotate the GO containing the particleFX, so far with no success.

How could i achieve this?

Try setting Emission Space to World in your particlefx.

I had it on World the entire time and it will not work.

If i have it on Emitter the rotation is correct, but the particle effect is just over the Sprite and no Trail.

EDIT: It seems to work now, i do not have to apply rotation to it because it already is rotated correctly. when i added rotation myself to the Emitter GO then it looked the same again. Now I know the behavour. Thanks
