Bells on collars

You know how people put collars that are equiped with bells on thier pets so they know when they are comming? Well I would like a plug in that makes a ringing sound that origionates from the Villagers and maybe decreases volume as it gets to 5 blocks away from the Villager. I ask for this because I am tired of turning around and gettin spooked by the guys because they sneek up on you!

is this not possible or somethin?

This would entail creating a new mob with a bell on it.

 

You could actually do it buy making a noteblock sound coming from the location of an NPC.

Code:

@EventHandler
public void onNPCTarget(EntityTargetLivingEntityEvent event) {
Entity e = event.getEntity();
if(e instanceof NPC && event.getTarget() intanceof Player) {
Player p = (Player) event.getTarget();
p.playNote(e.getLocation, Instrument.PIANO, Note. //Add the note here);
}
}

 

If I'm correct, thats only if the NPC targets the player.

 

I might be able to do this, so you want if the entity get's near the player, for it to play a noteblcok tune?
