Re: [Flashcoders] My first code.
Thank You So Much! :DI have been researching for over a
month!! I am guessing that the 'this' is pointing to the symbol or _mc I
attach the class to?
I ended up doing away with all of the "this" because I was receiving an error
message saying "gotoAndStop is not a function." Also I needed to declare the
variable "buttonState"
Here it is!!! My first Class!
Thank you!
###
package
{
import flash.display.MovieClip;
import flash.events.MouseEvent;
public class ToggleButton extends MovieClip
{
//public var togglButton:MovieClip;
public var buttonState = MovieClip;
public function ToggleButton()
{
// constructor code
//event listeners
addEventListener(MouseEvent.MOUSE_OVER, rolloverToggle);
addEventListener(MouseEvent.MOUSE_OUT, rolloutToggle);
addEventListener(MouseEvent.CLICK, toggleClick);
buttonState = "off";
// Respond to mouse events
function rolloverToggle(event:MouseEvent)
{
gotoAndStop(buttonState+" over");
} //rollover f(x)
function rolloutToggle(event:MouseEvent)
{
gotoAndStop(buttonState);
} //rollout f(x)
function toggleClick(event:MouseEvent)
{
if (buttonState == "on")
{
buttonState = "off";
} //if
else
{
buttonState = "on";
} //else
gotoAndStop(buttonState+" over");
} //toggle click f(x)
} //constructor f(x)
} //class
} //package

Everywhere you have "toggleButton" replace it with "this" or remove it
altogether.
In the linkage for the MovieClip that represents the toggle, put this class.

Re: [Flashcoders] problem with adding two digits
Oh yeah, I forgot to give some examples to test it with, so...
trace(floatSum(-0.1,0.9155,0.1,0.1,0.1,0.1,0.1,0.1,0.1,0.1));
//vs
trace(-0.1+0.9155+0.1+0.1+0.1+0.1+0.1+0.1+0.1+0.1);
//and
trace(floatProduct(2.1,0.1,1.0001,.0001));
//vs
trace(2.1*0.1*1.0001*.0001);

As people have said, it's a problem with decimals. It's not a problem
with
Flash--it's a problem with binary numbers.
Integers are accurate because all integers are a multiple of 1, and
binary
does just fine with combining 0's and 1's, the only possibile values
of a
digit in the binary system.
If you think of decimals as fractions, maybe it will help you
understand the
issue. In binary, a digit can only be a multiple of 2: 1/2, 1/4, 1/8/
1/16,
1/32, and so on. You can create numbers that aren't multiples of two by
adding multiple digits. For example, 1/4 + 1/8 = 3/8, or .375.
This works pretty well, until you get numbers with a lot of decimal
places.
At some point, you will find a decimal that is impossible to make using
powers of 2.
Cordially,
Kerry Thompson
