Need help to make "railgun" on my plugin

Hey, so I need gun to my minigame, that if you click *item* it would shoot maybe redstone particles and if player gets hit by those particles, that would maybe do little damage and stuff. I could not find any tutorials or plugins that would make this happend, so if anyone knows how to make this, that would be awesome <3

 

Synoctron actually, I have code that shoots stuff going straight, but it may not work the way you want it to

 

This is not tested, but I believe it'd be something like this:

Code:

                for(Block b : p.getLineOfSight(null, 20)){
                    b.getWorld().playEffect(b.getLocation(), Effect.STEP_SOUND, Material.REDSTONE_BLOCK);
                }

 

timtower woaosodo How i need it to work: Right click stick = shoot straight line of *particle here* = if particle line hits player, the line doesnt continue and then maybe broadcasts message or something

 

I'm getting the sense even you don't 100% know what you want.. Think it over, then come to forums.
