Hi Lan
I wrote a mousebehavior class that may help you.
I also add it to the viewplatformtransform
you can specify the translations/rotations as you mention (so without input from the
user).
However, it is a behavior class that is specifically written for my application so it
navigates maybe a bit strange for a regular user ;-).
You can drag yourself forward with the right mouse button while your altitude remains
the same. So only your x-axis direction affects the way you move.
Middle mousebutton drag changes your altitude and left mousebutton is to look around.
You can also invert the input for rotation and translation and you can also set the
speedfactors
I believe it's a good starting point to write your own behavior.
It was my first behavior class , so I don't know if it is really well written.
Anyone who has comments, please send me a message!
Also note that I had to replace the middlemousebutton mask with an integer since those
values don't match. Does anyone know what's the reason for that?
good luck
mattie
