Help with PacketPlayOutEntityMetadata

I would like to know if it is possible to edit a player entity's name using this method. I've tried messing with it and I don't get any errors when running, but the name does not change.

I came across the BasicHuman library and it implemented a "change name" function. The source was on GitHub and I copied and pasted the code (resolving import, class, and field name issues). When running and compiling there were no errors, but the name did not change.

Code:java

DataWatcher d = new DataWatcher( null );
d.a(0, (Object) (byte) 0);
d.a(1, (Object) (short) 0);
d.a(8, (Object) (byte) 0);
// String passed into the rename function
d.a(10 , (Object) (String) newName);
// 11 is "always show nameplate" according to the Protocol website
d.a(11, (Object) (byte) 0);

That is the information put into the data watcher before the packet is broadcast to all players on the server. Is there another way to rename the entity or a problem with this one?

Bonus question: Why is it required to add 0, 1, and 8 into the datawatcher? (The source I saw had it in all functions.) What are these indexes based on?

Thanks for any help.

Does anyone know if the name aspect of the packet is specific to non-player living entities? (Mobs)

This is a bump as I still have not found a solution.

Thanks, but that's what my code is based off of. I edited the '10' property in hopes of changing the entity's name (entity was spawned using PacketPlayOutNamedEntity), but to no avail.
