How to spawn a seperate scene with one node of type `CPUParticles2D` and set its position?

[crisp badger]

Hi guys,

ok I tried now so many things but I can't figure out how I can spawn one ore many Particle Spawners on a position of my choosing.

I have one scene that just constists of a CPUParticles2D node.
I have setup some nice looking particles and everything looks fine.

In my weapon scene when an area overlaps I want to spawn one of this scene as instance on the location of the object I hit (the enemy).
But no matter what I try it doesn't work.

Here is the code I have so far :

func _on_area_entered(area):
    var particles: CPUParticles2D = particleScene.instantiate() as CPUParticles2D

    particles.global_position = area.global_position
    particles.emitting = true
    add_child(particles)

This will spawn the particles but I can't see them at all.

This works, but they will spawn at the weapon, and not at the enemy i hit:

func _on_area_entered(area):
    var particles: CPUParticles2D = particleScene.instantiate() as CPUParticles2D
    particles.emitting = true
    add_child(particles)

I tried with normal position I tried with position of the parent with all kinds of variation and I also tried the box Local Coords on the Particle Node. Nothing every works.
When I add the particles as child of the object I hit, I get weird behaviour that all particles are cramped up together and form like one bigger particle.

Any ideas how I can implement a sytem that actually works? How can I set the position of a CPUParticles2D node?

Edit: I also found this thread on reddit: https://www.reddit.com/r/godot/comments/zw0xp0/so_particles_can_not_be_emitted_in_relation_to/
Is this really not possible?

Sorry thats not clear to me, i found a workaround that "kinda" works. Did it like this now:

var dir = global_position.direction_to(area.global_position)
    
    particles.emitting = true
    particles.translate(dir * 2)

set_emission_points take PackedVector2Array which is the same for CollisionsPolygon2D

[crisp badger]

but where are these emission_points come from ? They are not on CPUParticles2D arent they?

You can technically have them spawn from hurtboxes

collisionpolygons on your enemies

emission_points are technically array of vectos2d

[crisp badger]

it's not even like that deep. The problem is just when I set the position of the emitter directly via .position it gives weird behaviour. But now with .translate it works

[subtle swallow]

so you can use hurt_boxes amde of CollisionPolygon2D.polygon

[crisp badger]

because when I set the global_position of the emitter to the global_position of the enemy hit, it should be the same as calculating global_position of player - global_position of enemy (.diretion_to) and then translate the emitter by that amount. In my brain this should be the same, but only with translate does it work

Instead of having these particles emitting from the player/weapon, you can have them be emitted from the enemy.
