trying to serialize a struct, any ideas?

Hi all,

I'm trying to serialize a struct for purposes of sending it as a list through an RPC. I have it working great if it's a type string, but as soon as I change it to a struct that includes int, string, vector, etc.. it fails.

The failure is on the:

binf.Serialize( mems, testobjarray);

with the error:

Vector3 is not marked as Serializable


I've marked the class as serializable and the struct as serializable. Before I continue down a rats nest, can someone confirm if it's even possible to serialize a struct, and if so what's the trick to it?

Sample Code:


[System.Serializable]
internal struct State
{
internal float timestamp;
internal Vector3 pos;
internal Vector3 velocity;
internal Quaternion rot;
internal int objid;
}


void SomeFunctionThatWillSendAnRPC()
{
List<State> testobjlist = new List<State>();
State testobj = new State();
testobj.objid = 555;
testobjlist.Add(testobj);


BinaryFormatter binf = new BinaryFormatter();
MemoryStream mems = new MemoryStream();
binf.Serialize( mems, testobjlist);

networkView.RPC( "RemoteAvatarBatchUpdate", RPCMode.Others, mems.GetBuffer() );

}


Any help is greatly appreciated.

 

Yes, you can serialize a struct, but the stuff in the struct has to be serializable as well. Vector3 is not serializable.

This may help you: http://answers.unity3d.com/questions/498018/c-xmlserialize-a-struct-with-vector3-array-in-it.html

 

As far as I remember, Unity is unable to serialize structs. Why don't you try with a class instead?

 

Well if these are for messages being sent through RPC... and you're doing a lot of them... using a class means more allocation / garbage collection.

For something simple like you're doing I'd recommend looking at something like JsonObject in the asset store (it's free).

 

Thanks guys. I'll look into both. Maybe the trick is to store 3 floats instead of the full Vector3. Might be the quickest fix here.
