    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        if(sender instanceof Player) {
            Player p = (Player) sender;
            Guardian Guar = (Guardian) p.getWorld().spawnEntity(p.getLocation(), EntityType.GUARDIAN);
            Guardian Guar1 = (Guardian) p.getWorld().spawnEntity(p.getLocation(), EntityType.GUARDIAN);
            Guardian Guar2 = (Guardian) p.getWorld().spawnEntity(p.getLocation(), EntityType.GUARDIAN);
            Guardian Guar3 = (Guardian) p.getWorld().spawnEntity(p.getLocation(), EntityType.GUARDIAN);
        Guar.setTarget(p);
        Guar.setVelocity(new Vector(0f, 0.3f, 0f));
        Guar1.setTarget(p);
        Guar1.setVelocity(new Vector(0f, 0.3f, 0f));
        Guar2.setTarget(p);
        Guar2.setVelocity(new Vector(0f, 0.3f, 0f));
        Guar3.setTarget(p);
        Guar3.setVelocity(new Vector(0f, 0.3f, 0f));
       
        }
        return true;
