Solved Chest Open Animation - Error

Hello

I have a weird error when using Protocollib to achieve the chest open animation so that the inventory does not open.

Code:

PacketContainer chest = new PacketContainer(PacketType.Play.Server.BLOCK_ACTION);
                chest.getBlocks().write(0, Material.CHEST);
                try {
                    ProtocolLibrary.getProtocolManager().sendServerPacket(player, chest);
                } catch (InvocationTargetException ex) {
                    throw new IllegalStateException("Unable to send packet " + chest, ex);
                }

This code is run when a player right clicks a chest and I get an error which forces me to quit the server.

Error (open) Error (close)

Can someone tell me what I am doing wrong?

Thanks

 

@OllieGardner I don't know much about packets but don't you have to put in a location somewhere?

 

@pie_flavor I have some experience on packets (not with this specific one thought) but I assume yes indeed a location should be used at a point :/ I cannot find the packet to check the constructor ATM but I will ASAP,

 

@pie_flavor @mine-care Where about would I do that? I'm not very good with packets.

 

Does anyone know how I would add a location to my code?

 

@OllieGardner I think it's the first 3 int fields.

 

@OllieGardner

Code:

PacketContainer chest = new PacketContainer(PacketType.Play.Server.BLOCK_ACTION);
            chest.getBlocks().write(0, Material.CHEST);
            chest.getIntegers().write(0, x);
            chest.getIntegers().write(1, y);
            chest.getIntegers().write(2, z);
            chest.getBytes().write(0, (byte) 1);
            chest.getBytes().write(1, (byte) 1);
            try {
                ProtocolLibrary.getProtocolManager().sendServerPacket(player, chest);
            } catch (InvocationTargetException ex) {
                throw new IllegalStateException("Unable to send packet " + chest, ex);
            }

 

@OllieGardner Have you tried this?

 

@Konato_K Yes tried that but doesn't work in 1.8.

@WeeSkilz Very close.

For anyone who would actually like to know how I got it to work.

Code:

     
   PacketContainer chest = new PacketContainer(PacketType.Play.Server.BLOCK_ACTION);
        chest.getBlocks().write(0, Material.CHEST);
        chest.getBlockPositionModifier().write(0, new BlockPosition(chestLoc.getBlockX(), chestLoc.getBlockY(), chestLoc.getBlockZ()));
        chest.getIntegers().write(0, 1);
        chest.getIntegers().write(1, 1); //1 for open, 0 for close

        try {
            ProtocolLibrary.getProtocolManager().sendServerPacket(player, chest, true);
        } catch (InvocationTargetException ex) {
            throw new IllegalStateException("Unable to send packet " + chest, ex);
        }

You should run the code in a scheduler and run it every tick.
