are having problems:

I have followed the instructions of the doc photon ,
logic sever:
public override bool SetupInstance(IPluginHost host, Dictionary<string, string> config, out string errorMsg)
{
host.TryRegisterType(typeof(PlayerInfos), (byte)'a', MyCustomType.SerializeCustomPluginType, MyCustomType.DeserializeCustomPluginType);

return base.SetupInstance(host, config, out errorMsg);
}
private void ScheduledEvent()
{
PlayerInfos playerInfos = new PlayerInfos();

playerInfos.HP = 111; playerInfos.MP = 100;


Dictionary<byte, object> dic_data = new Dictionary<byte, object>();
dic_data.Add(2, playerInfos);
BroadcastEvent(10, dic_data);
}

client :
private void Awake()
{
Protocol.TryRegisterType(typeof(PlayerController), (byte)'a', MyCustomType.Serialize, MyCustomType.Deserialize);
}


Can anyone help me solve this problem?
