Forum ‹ BigDB ‹ Making a PlayerObject

[Beast]

Im adding playerobjects to my game, how can I make a users playerobject. Otherwise I have to do it manually to be able to set stuff within it?

You don't need to create it, just use the loadMyPlayerObject() convenience methods to load it, set some properties and save it back.

How do I do that serverside? Im trying to use the presence server example.

Code: Select all

   //We could have used PreloadPlayerObjects = true; but it's wastefull to load Player objects for people who just connects to send a message
                        player.GetPlayerObject(delegate(DatabaseObject o)
                        {

                            player.PlayerObject.Set("onlineStatus.state", (int)OnlineStatus.Online);
                            player.PlayerObject.Set("onlineStatus.seen", DateTime.UtcNow);
                            player.PlayerObject.Set("onlineStatus.server", RoomId);
                            player.PlayerObject.Save(delegate()
                            {
                                player.Send("inited",RoomId);
                            });
                            player.belongs = true;
                         

                        });

This Dosent make the object, but only sets it if the simple<user> object is there.

This Dosent make the object

Yes it does. You will always get that player's PlayerObject in the callback, but it might be empty if it was never saved before.

Well I get the error if I use a players object That i havent made in big db.

Object reference not set to an instance of an object.

at MyGame.MyCode.<>c__DisplayClass5.b__1(DatabaseObject o)

What does your code look like that throws that error?

[Beast]

Code: Select all

switch (message.Type)
            {
                case "init":
                    {
               
                        //We could have used PreloadPlayerObjects = true; but it's wastefull to load Player objects for people who just connects to send a message
                        player.GetPlayerObject(delegate(DatabaseObject o)
                        {
                           
                            player.PlayerObject.Set("onlineStatus.state", (int)OnlineStatus.Online);
                            player.PlayerObject.Set("onlineStatus.seen", DateTime.UtcNow);
                            player.PlayerObject.Set("onlineStatus.server", RoomId);
                            player.PlayerObject.Save(delegate()
                            {
                                player.Send("inited",RoomId);
                            });
                            player.belongs = true;
                         

                        });

                        break;

                    }
}

...and which line number throws the nullreference error?

[Beast]

It dosent say in the error log, but im pretty sure its the player.GetPlayerObject

[Beast]

Nevermind, I used Preload Playerobjects and now its fine.

Yep, the presence example assumes you have PreloadPlayerObjects set to true. Sorry for not outlining that in the example nfo.
