Help creating a Linked Trail for projectiles

I'm trying to make a custom grapple hook, i wanna make it so when the projectile shoots, it creates a trail from it which connects to the player and projectile while flying, and disappears when hitting a block, i know how to make particle effects spawn but don't know how to make them permenant until the projectile hits the block or how to make it link from me to the projectile kinda like a string connecting the two.
