Hey bukkit how would i make when i shoot a arrow until it hits an Entity or the ground i would leave a smoke trail ?
I'm unsure if there's a better way, however if you're wanting it to be ALL arrows, you could schedule a repeating task when the server starts up that watches for arrow entities, and emits smoke from the location of said arrow(s). Maybe.
I just want for the one the player shoots, i just don't know how to add the smoke on the trail i know it must be using Vector's but i cant just figure it out , kinda noob
Like Technes said: have some collection which holds the arrows you want to emit smoke and have a repeating task running which goes over that collection and checks if the arrows are still valid (marked for removal) / not yet landed (onGround), if this is the case play the smoke effect at the arrows location, otherwise remove the arrow from the collection. When a player shoots an arrow just add that arrow to the collection.
