    I am aware posts about this have been made before, however i have not found a solid answer... I need a simple, solid solution. I am aware this will require packets which I have not worked with yet.

    What i need is a solution which allows me to do ./away and it will make my body start sleeping. In mid air. This can be done as there is a command (I have forgotten) which allows you to do this i believe with Essentials. Please reply soon

    You need the plugin ProtocolLib on your server and you need the same version of it on your server AND your build path.

    Make sure ProtocolLib is installed on your server with the version you're using in your build and make sure you add it to the depend list inside the plugin.yml.

    Something to do with out of bounds location... I don't know why. I changed the loc from

    final Location loc = asleep.getLocation();

    to

    asleep.getLocation().getBlockX();
    asleep.getLocation().getBlockY + 1();
    asleep.getLocation().getBlockZ();
    etc and no difference.

    That's something to do with the ProtcolLib packets code and to be honest, I've never really messed with that, but yea it's an IndexOutOfBoundsException. Try checking if the size (bedpacket.getIntegers().size()) is greater than the index.

    Code:
            bedPacket.getIntegers().
            write(1, loc.getBlockX()).
            write(2, loc.getBlockY() + 1).
            write(3, loc.getBlockZ());
    is supposed to be

    Code:
            bedPacket.getIntegers().
            write(0, loc.getBlockX()).
            write(1, loc.getBlockY() + 1).
            write(2, loc.getBlockZ());
    But i don't think thats all the changes as it says the size is 1.

    EDIT: Nvm

    Code:
    private void broadcastNearby(Player asleep, PacketContainer bedPacket) {
        for (Player observer : manager.getEntityTrackers(asleep)) {
            try {
                manager.sendServerPacket(observer, bedPacket);
            } catch (InvocationTargetException e) {
                throw new RuntimeException("Cannot send packet.", e);
            }
        }
    }
    You are missing that method you need to call it in playSleepAnimation and stopSleepAnimation
