Serialization of nested classes

[Zelek]

Is there anything special that has to happen to enable nested serialization of objects?

I have a Party object on the server, and it contains an array of PartyMember objects. When I send the Party object to the client, Unity's OnExtensionResponse never gets triggered. I don't receive any exceptions on the client or server, and logging indicates that everything proceeded as planned. Sending just a PartyMember object seems to work fine.

I'm following the steps listed in the documentation and in Thomas's post on Sending/receiving classes. His example doesn't contain an array of serializable objects, though...is that allowed?

Hmmm - got some more details on what you exactly are sending?

Also beware that the class serialization stuff doesnt allow for generics (yet?). So that might be your issue.

Else paste a few code snippets!

The PartyMember object:

Code: Select all

public class PartyMember implements SerializableSFSType {
    public String name;
    public int portrait;
    public int type;

    // Necessary for serialization
    public PartyMember() {  }

    public PartyMember(String name, int portrait, int type) {
        this.name = name;
        this.portrait = portrait;
        this.type = type;
    }
}


Then I wanted to have a Party object which contained an array of PartyMembers:

Code: Select all

public class Party implements SerializableSFSType {
    // The list of PartyMembers in this Party
    public PartyMember[] partyMembers;

    // The maximum size of a Party
    public int MAX_SIZE = 10;

    // Necessary for serialization
    public Party() { }

    // Create a brand new party
    public Party(String name, int portrait, int type) {
        partyMembers = new PartyMember[MAX_SIZE];

        partyMembers[0] = new PartyMember(name, portrait, type);
    }
}


The ideal implementation for the partyMembers variable would have been a Hashmap<Integer, PartyMember> since the indices will often have gaps and not be sequential. Since your notes mentioned needing to use a Hashtable indexed by strings only, I thought an array would be more appropriate here.

After some fiddling, I got an error to show up in the server logs, mentioning that PartyMember[] did not implement SerializableSFSType (even though the PartyMember class did). Wasn't sure what to make of that, and ended up going with the less desirable Hashtable.

Will put your example through some paces here as a test case.

Thanks
