scaling problem

[franko]

I have been trying to scale a vector graphic which is a map.

I have the graphic in a mc called "map" it is just on one frame.

In the main scene, I have the movie clip in one layer and in a second layer I have a button which has the script

on (release) {
setProperty ("map", _xscale, getProperty("map", _xscale)+50);
setProperty ("map", _yscale, getProperty("map", _yscale)+50);
}


But nothing happens when the button is clicked. I would thing the x and y scale propterties would be increased by 50%.

any help would be appreciated.

Perhaps your paths are not quite correct... if the button isn't on the main stage this code iwllc ause problems so you're better off giving literal paths:

setProperty ("_root.map", _xscale, getProperty("_root.map", _xscale)+50);

you can also type it shorthand like this:

_root.map._xscale += 50;
_root.map._yscale += 50;

Saves a lot of typing huh? :)
Flash 5 supports the '+=' and '-=' operators, which take a variable and add (or subtract) the number after the operator.

So if I have avariable 'count' whihc is equal to 3.
count += 1;
will make count = 4, and
count -= 1;
will make count = 2...

thanks for your help on the short notation.

the problem was not one of paths. It was all in _root. But I was using the object name and had not assigned an instance name. Once I did that any of the variations of the code worked.
