Hi,

I have one main movieclip which hold multiple movieclips in it.  
The center of the main MC is set at the center of the stage.  
What I need is, if I click on any MC inside main MC, then that position (mouseX, mouseY) should shift to the center of the stage and the main MC should zoom from that point.

But I am not able to figure out how to do this?  
If I use tween class it move the center of the main MC to mouseX and Y position.  
I need is it should zoom from mouseX and Y position and also that point should shift to the center of the stage.

I tried using “MatrixTransformer.matchInternalPointWithExternal(matrix, internalPoint, i);”  
but it does not show smooth scrolling instead directly jumps to the required point.

I hope I’m clear with what I need!

Any solutions will be helpfull

Thanks in advance
