Changing slime's size (packets)

I want to spawn a slime with size 1, but I don't know how to set its size.
I have this at the moment:

Code:java

@SuppressWarnings("deprecation")
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args){
        Player player = (Player) sender;
 
        if(cmd.getName().equalsIgnoreCase("teste2")){
            PacketPlayOutSpawnEntityLiving jairo = new PacketPlayOutSpawnEntityLiving();
            try {
                Field a = jairo.getClass().getDeclaredField("a");
                a.setAccessible(true); // allows us to access the field
                a.set(jairo, 12345);
 
                Field b = jairo.getClass().getDeclaredField("b");
                b.setAccessible(true); // allows us to access the field
                b.set(jairo, (byte) EntityType.SLIME.getTypeId());
 
                Field c = jairo.getClass().getDeclaredField("c");
                c.setAccessible(true); // allows us to access the field
                c.set(jairo, (int) Math.floor(player.getLocation().getBlockX() + 0.5 * 32.0D));
 
                Field d = jairo.getClass().getDeclaredField("d");
                d.setAccessible(true); // allows us to access the field
                d.set(jairo, (int) Math.floor(player.getLocation().getBlockY() * 32.0D));
 
                Field e = jairo.getClass().getDeclaredField("e");
                e.setAccessible(true); // allows us to access the field
                e.set(jairo, (int) Math.floor(player.getLocation().getBlockZ() + 0.5 * 32.0D));
 
 
            } catch(Exception x) {
                x.printStackTrace();
            }
            DataWatcher watcher = getWatcher("Jairo");
            try{
                Field w = PacketPlayOutSpawnEntityLiving.class.getDeclaredField("l");
                w.setAccessible(true);
                w.set(jairo, watcher);
            } catch(Exception ex){
                ex.printStackTrace();
            }
            ((CraftPlayer)player).getHandle().playerConnection.sendPacket(jairo);
            player.sendMessage("Bem-vindo, Jairo!");
        }
 
        return false;
    }
 
    public static DataWatcher getWatcher(String text) {
        DataWatcher watcher = new DataWatcher(null);
 
        watcher.a(0, (Byte) (byte) 0x20); // Flags, 0x20 = invisible
        watcher.a(10, (String) text); // Entity name
        watcher.a(11, (Byte) (byte) 1); // Show name, 1 = show, 0 = don't show
        // watcher.a(16, (Integer) (int) health); //Wither health, 300 = full
        // health
 
        return watcher;
    }

 

You cant use
Slime s = (Slime) world.spawn(blah);
s.setSize(1);
?

 

I want to spawn the slime via packets.
Using your code, the slime will move and jump, even with negative jump effect and max slowness...

 

ArthurMaker oh duhh, sorry about that

 

Np.

Up!

Jeez, so much code.

PHP:

EntitySlime entity = (EntitySlime) ((CraftLivingEntity) world.spawn(player.getLocation(), Slime.class).getHandle();
entity.setSize(/* Slime size */);
PacketPlayOutSpawnEntityLiving packet = new PacketPlayOutSpawnEntityLiving(entity);

 

It doesn't work. e-e

What doesn't work?

 

Your code. It doesn't do what I want e-e
I want to spawn a slime that can't move or jump and with a custom name.
