I m using the scrollRect function to scroll around a large
map image. When
the user clicks the mouse I want to zoom in on the map, by
150%. I have used
_xscale and _yscale to zoom in, but this is where i m stuck,
its seems that
when I use the _xscale and _yscale on my image, it scales its
from 0,0 from
the top left, which means, that it zooms into the wrong place
on the image.
I guess I need to update the _x and _y of the scrollRect
rectangle, but I m
unsure of how to write this calculation. I need the visible
area to keep
showing the part of the image that the user clicked on.
