SyncListStruct<SquareStruct> - inner class synced only to host

Multiplayer & Networking

I have a board that is managed by the server
I couldn’t make SyncList work so i started working with SyncListStruct as it seems better performance wise.

I have these classes -

public struct SquareStruct
{
    public int slots;
    public int playerNumber;
    public int locationX;
    public int locationY;
    public List<Building> buildings;
}

public class Building
{
    public BuildingType building;
    public int level;
}
public class SquareList : SyncListStruct<SquareStruct> { }

I have the following SyncVar on a NetworkIdentity:

    [SyncVar]
    public SquareList squares = new SquareList();

and I populate this list and the clients are updated from it.
works great but - buildings is not syncing to clients - just the host is synced well.
I am aware that inner classes do not make the SyncVar “Dirty” - so after updating a square i do
squares.Dirty(squares.IndexOf(square)).

How can i make it sync to the client? I
I have - private void OnSquaresChanged(SyncList.Operation op, int itemIndex) as the callback to catch changes, the client gets the OnChanged call but the buildings list is null while on the host it’s full.

That’s not how SyncListStruct works. This applies to SyncListStructs as well as SyncVars:

You could make the Squares GameObjects with SyncVars and a SyncList for buildings, or use network messages to synchronize things yourself.
