EntityFallingBlock Smooth movement

Hi,
I am trying to make a plugin where a falling block follows players. I am using this code to send the packet:

Code:

for (Player pl : Bukkit.getServer().getOnlinePlayers()){
                        EntityFallingBlock entityfallingblock;
                        if(!blockMap.containsKey(pl)){
                            entityfallingblock = new EntityFallingBlock(((CraftWorld)Bukkit.getWorlds().get(0)).getHandle());
                            blockMap.put(pl, entityfallingblock);
                        }else{
                            entityfallingblock = blockMap.get(pl);
                        }

                        entityfallingblock.setLocation(pl.getLocation().getX(), pl.getLocation().getY(), pl.getLocation().getZ(), 0,0);

                        PacketPlayOutSpawnEntity packet = new PacketPlayOutSpawnEntity(entityfallingblock, 70, Material.JACK_O_LANTERN.getId());

                        for(Player player : Bukkit.getOnlinePlayers()){
                            ((CraftPlayer) player).getHandle().playerConnection.sendPacket(packet);
                        }
                    }

I use this inside a BukkitRunnable that repeats every tick to update the position of the fallingblocks. However, this creates jittery movement, and I am not sure how to make the movement smooth (like in HiveMC hide and seek).
Does anyone know how I can achieve smooth rather than jittery movement?
Any help is greatly appreciated, thanks!

Try setting the velocity of the falling sand.

 

I have tried doing this but the sand simply stays where it is. I am not sure if I am doing it right, but I was trying to set the velocity to the players velocity, not sure how else to make it go to the player :/

 

I used this code when trying to achieve the movement in PlayerMovementEvent:

Code:

@EventHandler
    public void PlayerMovement(PlayerMoveEvent evt){
        EntityFallingBlock entityfallingblock;
        if(!blockMap.containsKey(evt.getPlayer())){
            entityfallingblock = new EntityFallingBlock(((CraftWorld)Bukkit.getWorlds().get(0)).getHandle());
            entityfallingblock.setLocation(evt.getPlayer().getLocation().getX(), evt.getPlayer().getLocation().getY(), evt.getPlayer().getLocation().getZ(), 0,0);
            blockMap.put(evt.getPlayer(), entityfallingblock);
        }else{
            entityfallingblock = blockMap.get(evt.getPlayer());
        }

        entityfallingblock.getBukkitEntity().setVelocity(evt.getPlayer().getVelocity());

        PacketPlayOutSpawnEntity packet = new PacketPlayOutSpawnEntity(entityfallingblock, 70, Material.JACK_O_LANTERN.getId());

        for(Player player : Bukkit.getOnlinePlayers()){
            ((CraftPlayer) player).getHandle().playerConnection.sendPacket(packet);
        }

    }

 

I do it as I could not work out how to prevent the fallingblock from turning solid upon hitting the ground.
