Re[2]: [Flashcoders] Fuse is adding up instead of tweening the difference
Values obtained from XML attributes are always strings, but the
compiler doesn't know about that, since XMLNode.attributes is a simple
Object, hence no type hinting available (there is no such problem with
XMLNode.nodeValue, since it is declared as String).
MdMS I assign it to a variable of type number.
MdMS I thought that this would be enought to typecast my XML
MdMS retrieved untyped value to number
No, the compiler doesn't cast anything. Type checking is a
compile-time process, while casting values is a run-time one. There is
only type hinting in AS2, which means that during the compilation the
compiler doesn't allow using incompatible values if it knows both the
type of value to be used and the type of the required value where it
would be used. If one or another is unknown (no type hint) the
compiler cannot perform type checking and silently passes over that.
Hinting the type of a variable doesn't mean that it cannot hold values
of another types - it is only some help for the compiler for trying to
detect and avoid such situations. So when you assign the value of a
variable, which holds a string, but has no type hint (as members of
Object), to another variable, which is typed as Number, actually the
latter variable will contain the same string value.
Do not forget, that in fact AS2 compiler is a preprocessor only, which
produces the same output as AS1. If something cannot be done in AS1,
it cannot be done in AS2, too.

Hi Rákos,
Typecasting to Number() did the trick (i.e: Number(initHeight)). I'm intrigued
however.
Let me explain: The value comes untyped from a XML file (loadedthrough pixlib's
ConfigLoader). Once it is in the player (untypedObject), I assign it to a
variable of type number. Then I pass it to amethod that then does the following:
var initWidth:Number = initialWidth;
var initHeight:Number = initialHeight;
I thought that this would be enought to typecast my XML retrieved untyped value
to number but it seems that, even though I'm typing the variables to be a
Number (var:Number), FlashPlayers doesn't typecast the values to Number. It
only does so if Iexplicity call the typecast function Number() passing the
variable asan argument. Is this expected behaviour for ActionScript 2 ?
Thanks again,
Marcelo.

Hey guys, I'm having a really weird issue here. If someone could help me, I
would be really grateful.
I'm using the Fuse Kit (and ZigoEngine) to do the tweens of my AS2 Ria.
I've a MovieClip which gets stretched up and then after some seconds, needs
to get to its original size.
If I put the actual values of the width and height in the sequence (ex:
width:100,height:100) or typecast the variable to Number (which makes no
sense since it **is** already a Number) Fuse tweens the MovieClip from the
actual width,height to 100,100. However, if I use a variable, Fuse seems to
add to the current width,height, making the MovieClip even bigger instead of
tweening it to its original size.
These values are retrieved from a XML file using PixLib's ConfigLoader
class.
Here's the code:
initWidth:Number = this._initialWidth;
initHeight:Number = this._initialHeight;
var f:Fuse = new Fuse(
{
target:this.view,
start_width:this.view._width,
start_height:this.view._height,
width:initWidth, //If I put a number here, it works
height:initHeight, //If I put a number here, it works
x:this._initialGrid_x,
y:this._initialGrid_y,
ease: easeOutBack
});
f.start();
(...)
**However**, if I typecast the initWidth and initHeight like this:
var f:Fuse = new Fuse(
{
target:this.view,
start_width:this.view._width,
start_height:this.view._height,
width:Number(initWidth), //or put the actual value, such as 100
height:Number(initHeight), //or put the actual value, such as 100
x:this._initialGrid_x,
y:this._initialGrid_y,
ease: easeOutBack
});
f.start();
(...)
...It works as expected (it tweens-down to 100, not adds-up to the current
width,height). However, I have no idea why... could someone enlighten me on
it ?
Thanks in advance,
Marcelo.
