Suggestions for smooth camera zoom in & out

[mattdravucz]

Hi, I would like to add camera zoom in & out with mouse wheel up and down. I tried to different ways to implement it but in both case I can't figure out how to use smooth transitions for the camera.

1. Implementation:

The functionality works but the smooth transitions does not.

2. Implementation:

• Zooming state is the same but with CameraDistanceAfterZoom

The only way I could make smooth transition was using the 2. implementation and between MMODirection and Zooming I used a notification in transition rule called: End Transition Event but that way you have to wait till the smooth transition happens and scroll again to zoom in or out every time so its not really "smooth/fluid".

If someone could tell me what is the best way to implement something like this and how to make the smooth transition working I would really appreciate it. The smooth zoom effect that I wanna achieve is similar like in Word of Warcraft for example.
