msgpack with unity sample. used msgpack_cli(project=MsgPack.compats.Net.3.5 ,target framework=mono3.5). builded binary https://www.dropbox.com/s/rbnamvknbvwx58h/MsgPack.dll

DataClass.cs

using MsgPack;

public class DataClass  : IPackable, IUnpackable{
	public string data;
	public int count;

	public void UnpackFromMessage (Unpacker unpacker)
	{
		unpacker.ReadInt32(out count);
		unpacker.ReadString(out data);
	}

	public void PackToMessage (Packer packer, PackingOptions options)
	{
		packer.Pack(count);
		packer.PackString(data);
	}
}

Test.cs

using System.IO;
using MsgPack;
using UnityEngine;

public class Test : MonoBehaviour {

	void Start () {

		byte[] bytes = null;

		// pack

		var data = new DataClass()
		{
			count = 120,
			data = "hoge",
		};
		using ( MemoryStream mem = new MemoryStream())
		{
			Packer packer = Packer.Create(mem);
			data.PackToMessage(packer, null);
			bytes = mem.ToArray();
		}

		// unpack

		DataClass unpackData = new DataClass();
		using (MemoryStream mem = new MemoryStream(bytes))
		{
			Unpacker unpacker = Unpacker.Create(mem);
			unpackData.UnpackFromMessage(unpacker);
		}


		Debug.Log(unpackData.count);
		Debug.Log(unpackData.data);
	}
}

Thank you for making a Unity version for MsgPack. I will test it out.
Cheers. Arigato.
