Hello World!
I'm talking about scene transitions in Alice3.
I have the movie of the bunny in the snow and the  desert that I created previously.
Let's just run that,  and you can see there's no transitions.
It just goes directly from one scene to the other.

I'm going to create a transition.
Let's go to Setup Scene.
What I'm  going to do is add a billboard.
I need the billboard to be in front of everything.
So let's just move that forward and resize it.
And I want it to cover absolutely everything.
We could and also do that by changing the width by typing in something like 5.
Now what I'm going to do is set the color to black
and go back to edit my code.

Let's go back to this, and under procedures we have setupSnowScene.
I'm  going to edit that.
At the beginning of the scene I'm going to make the billboard change to an opacity of 1.
And do that gradually.
And then the once the scene is set up, I'm going to change that to an opacity of 0.

I've only done that for the snow scene.
Let's copy that to the clipboard, go back to this
and edit my desert scene.
Again, were going to set the opacity to one at the start and to zero at the end.
Let's run that.  And he gradually fades in,
he gradually fades out,  fades back in, and we have a transition.
And that's it!
