Making a player sit down

Here's a video of what I want to do with the player:
I've coded the following code, it just does not work

Code:

public void sendArmorStandPacket(Player player) {
        EntityPlayer nmsPlayer = ((CraftPlayer) player).getHandle();
        PacketPlayOutSpawnEntityLiving field = new PacketPlayOutSpawnEntityLiving();

        field.a = 30;
       
        int x = (int) player.getLocation().getX();
        int y = (int) player.getLocation().getY();
        int z = (int) player.getLocation().getZ();
        field.c = (x);
        field.d = (int) (y + 1.0);
        field.c = (z);

        sendArmorStandMetadata(field.l);

        PacketPlayOutAttachEntity sitPlayer = new PacketPlayOutAttachEntity(0, nmsPlayer, armorStandEntity);

        nmsPlayer.playerConnection.sendPacket(field);
        nmsPlayer.playerConnection.sendPacket(sitPlayer);
    }

    public DataWatcher sendArmorStandMetadata(DataWatcher dataWatcher) {
        DataWatcher metadata = new DataWatcher(armorStandEntity);

        metadata.a(0, (byte) 32); // Invisible = 0x20
        metadata.a(1, (short) 300);
        metadata.a(7, 0);
        metadata.a(8, (byte) 0);
        metadata.a(9, (byte) 0);
        metadata.a(6, 1.0F);
        metadata.a(10, (byte) 8); // NoGravity
        return metadata;
    }

I want to spawn an armor stand and set the player as passenger. Hope somebody help me

 

Why do you use nms for this? This can be done with player.setVehicle(Entity)

 

@mcdorli Exactly. usually such plugins that make players "sit" drop an item like an arrow or seeds or whatever and attach the player on it.

 

@Alfalik
I can't do it for you, but I can give you these:

Code:

// Spawn stand
World.spawn(Location, Class)
// example
player.getWorld().spawn(player.getLocation(), ArmorStand.class);

// Make stand invisible
// Then put player on stand

 

The deal of NMS/packets is that others players can't see, in this case, the armor stand. I don't want other players to see the armor stand, that's why.

I'm using packets to spawn the armor stand. I can't get to work the PacketPlayOutAttachEntity packet (the armor stand is spawning), wonder if you know and check my code, thanks in advance.

Code:

public void sendArmorStandPacket(Player player) {
        EntityPlayer nmsPlayer = ((CraftPlayer) player).getHandle();
        EntityArmorStand entityArmorStand = new EntityArmorStand(nmsPlayer.getWorld());
        PacketPlayOutSpawnEntityLiving armorStand = new PacketPlayOutSpawnEntityLiving();

        try {
            armorStand.b = (byte) 30;
            armorStand.c = (int) (player.getLocation().getBlockX() * 32.0D);
            armorStand.d = (int) (player.getLocation().getBlockY() * 32.0D);
            armorStand.e = (int) (player.getLocation().getBlockZ() * 32.0D);
            armorStand.f = (byte) (int) ((player.getLocation().getYaw() * 256F) / 360F);
            armorStand.g = (byte) (int) ((player.getLocation().getPitch() * 256F) / 360F);

            DataWatcher armorStandMetadata = new DataWatcher(entityArmorStand);

        } catch (Exception e) {
            e.printStackTrace();
        }

        PacketPlayOutAttachEntity attachEntity = new PacketPlayOutAttachEntity(0, nmsPlayer, entityArmorStand);

        nmsPlayer.playerConnection.sendPacket(armorStand);
        nmsPlayer.playerConnection.sendPacket(attachEntity);
    }

 

@Alfalik
If the server doesnt know the armour stand exists, how will it show other players that the player sitting on it is doing so?

 

I don't want other players to know that the player is sitting, it'll be client-side

 

It may be possible to send a packet that makes a player sit without an entity. I don't use packets that much but I think it'll be good to find out.

@Alfalik @teej107

 

That uses a spawned entity.

It may not be possible and I would be surprised if it wasn't.

EDIT: However spawning an entity seems like the only solution AFAIK

 

Make the player sit on himself

 

@teej107
So?
Whats wrong with a spawned entity?

That thread shows that you can make the entity invisible, or use a destroy entity packet

If doing the latter, the other players dont even see them sitting


Isnt that exactly what is wanted here?


@xTrollxDudex
Did you read any of the posts after the original one?

 

Because you shouldn't need to spawn an entity so you can sit. That is why I think it is possible to do it without one.

 

@teej107
There's plenty of things that you should be able to do.. doesn't mean Bukkit lets you do it.

But I agree, there should be a way to do it, I just gave you that option given that it's the easiest && most stable

 

I wouldn't call sending packets "Bukkit". Especially with sending packets, I don't think there is a "doesn't let you" or "lets you". There either "is" or there "isn't". And it is entirely possible that there isn't a packet to make a Player sit.

EDIT: I can't find the thread that I also seen about this but why wouldn't making a Player sit on himself work? If that doesn't work, I found this: http://bukkit.org/threads/making-a-player-sit-down.111381/#post-1422347 it's outdated but if you find the current packet for it then it's a start and it might work if making a Player sit on himself doesn't work.

 

I just want a player sitting on a armor stand, don't care about others players.

Sit the player on himself just glitch the camera and movements of the player.
About the issue, the entity is being spawned (the armor stand), the PacketPlayOutAttachEntity is not working as it should. Nothing happens when I call the method, only the entity being spawned. What's wrong with my code?

Code:

public void sendArmorStandPacket(Player player) {
        EntityPlayer nmsPlayer = ((CraftPlayer) player).getHandle();
        EntityArmorStand entityArmorStand = new EntityArmorStand(nmsPlayer.getWorld());
        PacketPlayOutSpawnEntityLiving armorStand = new PacketPlayOutSpawnEntityLiving();

        try {
            armorStand.b = (byte) 30;
            armorStand.c = (int) (player.getLocation().getX() * 32.0D);
            armorStand.d = (int) (player.getLocation().getY() * 32.0D);
            armorStand.e = (int) (player.getLocation().getZ() * 32.0D);
            armorStand.f = (byte) (int) ((player.getLocation().getYaw() * 256F) / 360F);
            armorStand.g = (byte) (int) ((player.getLocation().getPitch() * 256F) / 360F);

        } catch (Exception e) {
            e.printStackTrace();
        }

        PacketPlayOutAttachEntity attachEntity = new PacketPlayOutAttachEntity(0, nmsPlayer, entityArmorStand);

        nmsPlayer.playerConnection.sendPacket(armorStand);
        nmsPlayer.playerConnection.sendPacket(attachEntity);
    }

 

bump. Still can't get the player sitting on the armor stand (the armor stand packet totally works)
