Need help for coding "railgun"

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

 

Get the players line of site, send reddust particle packets to nearby players, check if any LivingEntities are inside the players line of site that != the shooter, and damage those entities.

 

Skionz He can use also vectors ? It would be easier i think. Of course only to display this particles

 

Plugers11 can't apply velocity to particles

 

use packets to make an arrow invisible, detect where arrow is and spawn redstone particles on the arrows location? set the damage of arrows to the damage you want the railgun to do?

 

Monkeyboystein That would require a scheduler and there are only 20 ticks per second so you wouldn't have many options for speed. I would just use the LivingEntity#getLineOfSight() method.

 

Deprecated. (Hehe line 69)

Using a BlockIterator or incrementing a vector would be an accurate/fast/non-deprecated solution.
