Hi, i’ll probably won’t get any answer but i’ll still ask,

I’m trying to spawn an Emitter and it’s only working with an input action key.
Tried calling it from Blueprint interface, execution is passing but no Particule and nothing in the timeline after.
so i did Try to make a Custom Event, and also calling it, but again, execution is passing and nothing happen.
So i made a Input action key, and it’s working execution is passing and stuff happen,
Now here is my question, Why that ? i don’t want to use an Input action, i’m adding a screen.

if someone know the answer, you welcome to share. thanks again if someone ever answer.

Does the Input action do anything else anywhere?

it does, has the custom event and interface event, that’s why i don’t understand why it doesn’t work here. For now i just skip that part of the code, but i would gladly get it back as soon as i figure it out.

for now there’s only the input action that make the code work as intended ( spawning the emitter)
Everything else just skip the emitter part.
