Particles damage

My god being able to do this kind of interaction with particles would be incredible, I hope someone who knows how to answer that

A possible solution would to make a particle effect and a procedure trigger in the same place.

You could do the damage through a few ways:

effects (through commands)

collision with a custom mob (for the hitbox of the particle)

spawn a splash potion (also through commands)

custom code

There are probably other ways to do this as well.

particles don't have hitboxes and can't do damage. just spawn the particle and use the "damage entity" code block right after

I know that this is two months old but I found a solution. So you could create a projectile that does damage but it spawns particles around it.
