Looping Through Locations

I'm trying to create particle effects in the straight line that a player is looking in up to 7 blocks away. I used this code:

Code:java

 
 
    public void createParticles(Player player){
        Vector direction = player.getEyeLocation().getDirection();
        double angle = direction.angle(new Vector(0,0,1));
        double x = Math.sin(angle);
        double z = Math.cos(angle);
 
        for(int i=1;i<=7;i++){
            Location loc = player.getLocation().add(x * i, 0, z * i);
            ParticleEffect.LARGE_SMOKE.display(loc, 15, 0, 0, 0, 10, 3);
        }
}

I am using THIS for my particle effects. For some reason, the particles seem to be spewing out in all directions from the player's location when I run through this. Is there anything you can see that I'm doing wrong? Thank you!

 

Hmm idk the solution but change your title to looping no cycling
