Projectile type problem

Thx for your input but

It does the contrary of what you are saying… the particle do switch but only in the projectiles that are already been launch and I have to spam the number for the particles to switch to what I want

I just want to set the visible particle using 1 2 3 and keep it constant to that un toll I press another button

Still, I will look up the communication blueprint you are talking about
Thx again

Anyone else??
