Launch Fire Projectile

So I was watching a few videos and one was a server gameplay where a player actually launched the fire block at someone. I was wondering how would you actually do this?

You could either use the fire item or a projectile. For the fire item, you would need to spawn a fire item drop at the player's location, make it unable to be picked up, set it's velocity to player.getLocation().getDirection() (and multiply that depending on how far/fast you want it to go) and then create a scheduler that will check if the block under it's location is not air. Then, spawn fire on the block.getRelative(BlockFace.UP). For projectile, make the player launch a projectile, save it's UUID in a List<UUID>, listen for ProjectileHitEvent, check if the list contains the event.getProjectile().getUniqueId(), and then get the projectile location, spawn fire there and remove the projectile.

You could spawn a FallingBlock and set its block type to fire. Then you will have to set its velocity.

 

Ok I have two questions.
I currently have this:

Code:java

FallingBlock fire = player.getWorld().spawnFallingBlock(player.getEyeLocation().add(player.getLocation().getDirection().normalize()), Material.FIRE, (byte)0);
fire.setVelocity(player.getLocation().getDirection().multiply(2));

How would I be able to check if the fire block hit a player.
And, when the fire lands, it places it on the ground which isn't a problem on most surfaced but on leaves/logs it spreads and all and on netherrack it just sits there. My question is, is there a way to leave the fire there for a second then remove it without affecting any other fire on the map?

 

Have a sync repeating task checking the positing and then check for collisions with other players.

I'm sorry but how would I do that?

And do you have any ideas for the second part?

 

Pseudo code:

new bukkit runnable {
entity e = get closest entity
if distance to e < .5 blocks {
light on fire and remove
}
}.run repeating task
