Mob manipulation

So i'm trying to make a mob where when i type /nskelly it will spawn a seletons to hold axes instead of bows they stay still and every 3.5 second they throgh an axe at you if your in a range of 20 blocks my friend said to id hook it up so they shoot snowballs replace the snowball entity to the axe item as for spawning in one you'll need to use packets make it so the entity doesn't want to move and it will target players but i have no clue how to do could some one show me how or show me the some helpful bukkit javadocs i can use! Thanks

Here's the code to spawn a skeleton with a diamond axe instead of a bow. I know it's not exactly what you asked for, but here's a start for you

Code:java

@Override
public boolean onCommand(CommandSender sender, Command cmd,
String commandLabel, String[] args) {
Player player = (Player) sender;
if (commandLabel.equalsIgnoreCase("test")) {
Skeleton skeleton = (Skeleton) player.getLocation().getWorld()
.spawn(player.getLocation(), Skeleton.class);
 
ItemStack axe = new ItemStack(Material.DIAMOND_AXE);
skeleton.getEquipment().setItemInHand(axe);
}
return true;
}
