[MX] Modify scale and alpha of image via input txt boxes

[Demonia]

I really need some help please. I have just started learning AS from this book and am having a little trouble. I have to make a thingie whereby when u enter values into 2 input txt boxes an image modifies its scale and alpha accordingly. Now I have done everything I am supposed to but the funny thing is NOTHING happens. I'll post the code (I applied it to the button which I think is right)...

on (release, keyPress "<Enter>") {
if (_root.scale>100) {
gotoAndPlay(1);
} else {
myClip._alpha = "opacity";
myClip._yscale = "scale";
myClip._xscale = "scale";
}
}

The script on frame 1 is

scale = " ";
opacity = " ";
_root.myClip._alpha = 100;
_root.myClip._yscale = 100;
_root.myClip._xscale = 100;

and on frame 2

stop ();

I need to figure this out cause I don't see the point of going on if i don't understand what's wrong with this...

Thanks a billion,

D :beam:

First off, you're setting the scales to a string, "scale", not the variable, so kill the quotes. Now with text boxes, the value in any textbox will always be a string, so you have to do a little type conversion. In this case, you want Number(value);

so change this:
myClip._alpha = "opacity";
myClip._yscale = "scale";
myClip._xscale = "scale";
to this:
myClip._alpha = Number(opacity);
myClip._xscale = myClip._yscale = Number(scale);


Lastly with the textboxes, make sure that their variables are set, not just the instance name, to "scale" or "opacity" (w/o quotes).

Thanks for your time but unfortunately it still doesn't work...

Please do not look at the design ... I just plonked some stuff in there to try and do this (in other words it looks like it's been put together by a rhino) :sigh:

I don't know how to get it to you cause it;s 220 kb :( and zipped it's 180 kb ... please help
Thanx,

Here, let me give you an FLA instead showing you how it's done.

Here you go, sorry for the delay, i'm at work so i have to balance everything out.

Anyway, I put this together real quick, but it works.

Pay close attention to all the details in this movie, including variable names, instance names, actions, etc.

Thank you very much - I understand now how it works :beam: ...
