RE: FLASH: [xpost] magnify with different levels of detail

[Paul Willoughby]

Hi Richard,


To zoom in, all you have to do is scale up the map using SetProperty.

You should put this action on a button with an onRelease action.

Probably the best way would be to have different buttons with different

actions for the different areas you want to scale. You're also going to

need some code to move the map (again using SetProperty), because

setting the scale will scale it up based on the centre point of the

entire map Movie clip (you have made your map into a movie clip haven't

you?).

To reveal details you can set the visibility or alpha of the relevant

elements according to the map's scale.


What you're talking about doing is really quite a large project.I worked

on a similar project, which you can see at

http://www.nottinghillcarnival.net.uk/flash_map.htm . When you click on

'make map big' the map scales up and new road names are faded in. This

is simpler than what you are describing, and took about a four days to

code up from a basic Illustrator design. Hate to fish, but if you're

interested in farming the work out contact me off list.
