so in minecraft i can summon particles with commands from the player eyes, and the particle spawn like a laser( https://imgur.com/a/kZjxeK2 ), how can i do that with the world.addParticle

You're going to need to spawn multiple particles.

You can use a for-loop for that.

Pseudo code:

for (int i = 0; i < detail /* how much to spawn */; i++) {
	world.addParticle(/* Particle info goes here ... */, /* X: */ (destX / detail) * i);
}

(That won't actually work you will need to make your own adjustments
