Need help with custom item creation

[DesertedPlanet]

I've been trying to create a custom item that can use a modified version of the lunar guardian's phase 2 spike attack where it causes a line of spikes to form. I want to do that for the weapon that I'm making on right click, but instead in a straight line. How would I replicate this code in a component? The reason I want to modify this particular is because I intend for the weapon to be a gun that can also friendly fire, so I wanted to reskin the spikes into a projectile.
