Upgraded Scenes not working with TXB 2.0

I have a problem with some code that was working fine with TXB 1.0, that since has been upgraded to 2.0

I've been using:

StarterGame.Game.Instance.SceneLoader.UnloadLastScene();
// or StarterGame.Game.Instance.SceneLoader.Unload(@"data\levels\l" + old + ".txscene");

then..

StarterGame.Game.Instance.SceneLoader.Load(@"data\levels\l" + val + ".txscene");

to unload levels, and to load a new one, where val is the level number and old was the currently loaded level

Aside from a few objects that had to be unregistered, this worked fine with TXB 1.0. In TXB 2.0 however, using this just results in a blank screen (no errors, just blank!). Removing the .UnloadLastScene part gives me the two levels merged, as I would expect to see.

Any ideas why this would be happening or how to fix it? I ran into the >80 objects issue, which I fixed as described with the code below..

T2DSceneCamera cam = TorqueObjectDatabase.Instance.FindObject("Camera"); cam.FarDistance = 10000f;

I'm also calling SceneLoader from with a function inside the standard MovementComponent, which is attached to my player, which I then unregister, which is probably not the most genius idea. I had to change the type from T2DStaticSprite to T2DAnimatedSprite as it was barfing after the upgrade (it is an animated sprite, so I assumed I just made a typo before..)

I just ran into this problem myself today. It looked like the call to UnloadLastScene() wipes out the current sceneview along with everything in it. I ended up creating a new sceneview and then switching to it. I'll check my code and post it later, but it was something like this...

GuiSceneView newscene = new GuiSceneView();
GUICanvas.Instance.SetContentControl("GuiSceneView");

Again, I'll put together some real code, but it went something like this.

Hi John

Thanks for this.. I ended up doing the following (had to include GarageGames.Torque.GUI)

//create a renderable canvas for the scene
GUIStyle stylePlayGui = new GUIStyle();
GUISceneview playGui = new GUISceneview();
playGui.Style = stylePlayGui;

//switch over to the new canvas and load in the new scene
GUICanvas.Instance.SetContentControl(playGui);
StarterGame.Game.Instance.SceneLoader.Load(@"data\levels\l" + val

This worked for me, then I ran into the 80 objects problem which I tried to fix in the way described above, only to find that "Camera" no longer seems registered and so the search comes back null. In fact I couldn't find any camera's in use at all, so not sure what's going on there, or why I can see the screen in the first place!

So I tried to set the playGui object, since that has a Camera property..

playGui.Camera.FarDistance = 10000f;

And that also barfed because it's saying the object is read only.. any ideas how to work around that one?

Many thanks

Paul

OK, fixed this now.. just needed to put the Camera code in the _OnRegister function ;-)
