Saving Games in TorqueX, on your 360 or PC

This quick and dirty sample of how to get save game features working on your XBox and PC.

First Open a StarterGame, find your game.cs, and make your begin run look like this

protected override void BeginRun()
        {
            base.BeginRun();
            
            
#if XBOX360
            //Create an XboxStorage Device Object, that will keep track of our Device, and make sure it does what we want.
XboxStorageDevice myXboxStorage = new XboxStorageDevice();
            //Name it, so we can find it in code using the TorqueObjectDatabase
            myXboxStorage.Name = "MyXboxStorage";
            //Give it a tick, so it can fire off saves and loads, after the device has been found.
            ProcessList.Instance.AddTickCallback(myXboxStorage);

#endif


            //Load our Scene, just a single ggPlayerObject, offscreen, with no velocity or anything. 
            //(just apply to it a world Limit and "Rigid Physics" for world Limit Collision Resolution)
            SceneLoader.Load(@"data\levels\levelData.txscene");
            //Create Our Save LoadObject
            SaveLoad _saveLoad = new SaveLoad();
            //name the object, so we can find it using the TorqueObjectDatabase
            _saveLoad.Name = "SaveLoad";
            //Activate an input map, so it can load and unload our game as well as move our "player buddy" around
            _saveLoad._SetupInputMap(_saveLoad, 0, "gamepad" + 0, "keyboard");
            //Load Initial Data, so we can have the option of loading a "New Game"
            _saveLoad._loadInitialData();
            //Give it a tick callback, so it can move our "player buddy" around
            ProcessList.Instance.AddTickCallback(_saveLoad);
        }

Grab your movement component, and cut out all the _sceneObject stuff, including the on Register method, unregister, etc, make it look like this...

}

Next, open up your "levelData" in your TXB editor. Remove the movement component if its not gone already. Drag the gg logo outside the viewable area. Mark it as a template. Give it a WorldLimit, and apply rigid physics so we can get some angular velocity on our bounces. (Remeber to size the world limit to the size of your screen/camera), (so we can see whats going on!) Name it "ggPlayerObject".

Finally, Create two new classes, with the following code in each.

            container.Dispose();
            return playerData;
        }
  
    }
    
}

That should pretty much do it. Dont forget to add a reference to System.XML in your game.

My references, were mostly taken from the GSE Help, Contents. Check under Programming Guide, Storage.

Also...(http://www.virtualrealm.com.au/blogs/mykre/archive/2007/05/06/xna-storage-the-beginning.aspx)

And of course, the GG TX forums

You can save and load all 4 properties of the GG Logo, accross multiple games and loads on your XBox or PC. Now I'm going to go put this in MY game..

enjoy,

Heres a Sample Picture of what it might look like..
