Explanation of TX code flow...

Hi,
Can someone explain the code flow for the StarterGame starter kit.
It seems that the Game class is instantiated and _mygame.Run() is called from the Main() method. I can't see this method's source but I assume it calls _mygame.BeginRun() before doing something.
_mygame.BeginRun() loads the scene that is created using TGBX and then I don't know what happens.
I assume that there is an event pump somewhere hidden away driving the ticker I read about in the Overview.html documentation.
I had a look inside the MovementComponent class and this is another mystery. I assume ProcessTick() is being called from the hidden event pump and the _InitComponent() method was called when _mygame.BeginRun() loaded the scene.
Can anyone shed some more light on this?
Thanks,
T

You are passed a reference to the owning object, which you can then (if you choose to), cache within your component for future use.
For example,
_ownerObject = Owner as T2DSceneObject;
(where _ownerObject is defined as a T2DSceneObject).
As far as what's going on in the SceneLoader.Load method, basically the XML file (.txscene file) is deserialized. Each object / material, etc. is loaded up and either registered with the scene (in the case of objects whose IsTemplate flag is false), or for templates at least loaded into the TorqueObjectDatabase for future lookup / cloning.
Hope this sheds SOME light on things :)

Ty, _InitComponent is called on each component as its owner is actually registered with the SceneGraph.You are passed a reference to the owning object, which you can then (if you choose to), cache within your component for future use.

_ownerObject = Owner as T2DSceneObject;
