Error in my MessageBase inheritance tree

Hi everybody. I have several types of custom MessageBases. One of them acts as a base class for most of the others. As an example:

MessageBase > LockstepMessage > SelectMessage

My LockstepMessage class looks like this:

Code (csharp):

1.  
2. [Serializable]
3. public class LockstepMessage : MessageBase
4. {
5.     public int team;
6.     public int frame;
7.     public float averageGameFrames;
8.     public float averagePacketTime;
9.  
10.     public LockstepMessage()
11.     {
12.         team = NetworkInfo.localPlayer;
13.         frame = NetworkInfo.commandNumber;
14.         NetworkInfo.commandNumber++;
15.         averageGameFrames = FrameManager.instance.GetAverageFrameRate();
16.     }
17. }
18.  

When I use a Network Writer/Reader to send/receive a derived message:

Code (csharp):

1.  
2.         NetworkWriter nw = new NetworkWriter();
3.         nw.StartMessage(MessageTypes.SelectToServer);
4.         select.Serialize(nw);
5.         nw.FinishMessage();
6.  

Code (csharp):

1.  
2.         SelectMessage select = netMsg.ReadMessage<SelectMessage>();
3.  

The base class variables don't seem to deserialize properly, but the derived class (SelectMessage) members deserialize fine. Is it because my SES sets the vars? What's the proper way to do this?

Thanks for your time.

 

It might be that unitys auto serialize/deserialize magic for MethodBase might be limited to a single inheritance.
Someone else seems to have the same issue as you

Thanks, that helped a lot. Manually overriding the Serialize and Deserialize functions worked perfectly. Unfortunately, this brings up a new problem. How do you deserialize a List of ints with a NetworkReader?

 

To serialize and deserialize lists you are going to need to maybe make an extension method or something that you can pass the list to serialize.
The serialize will need to first serialize the Count of the list and then it will loop over and serialize the list itself.
The deserialize will need to then read the bytes to get the Count first, and then it can loop using the Count and deserialize all the contents.
