Particle slash on right click.

So I understand there are tutorials out there on how to do this for left click swinging an item, but there is nothing for a right click.

It's really basic what I need, just a line of particles to spawn in front of the player whenever the item is right clicked. I am adding this a procdeure and I know this should be simple enough. To clarify, I DON'T NEED FANY GEOMETRY. 

Just a LINE of particles to appear in front of the player.
