this.addEventListener(Event.ENTER_FRAME, cpF1);
this.addEventListener(Event.ENTER_FRAME, cpF2);
 
function cpF1(e:Event):void{
trace("cpF1")
}
function cpF2(e:Event):void{
trace("cpF2")
}

Don’t expect to have traces like “cpF2″ only. You’ll have “cpF1 cpF2″ traced on every frame. This is a very hard to find mistake, if you expect an object to have only one onEnterFrame listener but you add another.

Have you ever seen this error, when trying to move your fla from AS2 to AS3:

“Location: tempInit, Line 2   Description: 1086: Syntax error: expecting semicolon before line.”

In my case the problem was that I had a movieclip with a Linkage identifier in my AS2 file that contained space in the name. When I moved to AS3 all my Linkage identifiers were converted to class names and when I tried to compile my AS3 flash file I got this error above.

So be careful when you name your linkage identifiers. Better use “camel case” instead of using spaces. This will help you move your AS2 fla file to AS3 fla file without seeing this error.

Happy coding!

In a comment on my previous post [AS3] Skinning Flash Components I was asked to show how to change the size of the thumb of the Slider component. After some experiments with the component here is the way it can be done:

import fl.controls.Slider;
 
var s:Slider = new Slider();
s.move(10,10);
s.setSize(500,300);
/*s.setStyle("thumbUpSkin", SliderThumbCustomSkin);
s.setStyle("thumbDownSkin", SliderThumbCustomSkin);
s.setStyle("thumbOverSkin", SliderThumbCustomSkin);*/
s.maximum = 100;
s.minimum = 0;
s.tickInterval = 5;
addChild(s);
s.getChildAt(1).width = 50;
s.getChildAt(1).height = 100;

With the code above I found that the thumb of the Slider component is positioned at index 1 and can be reached by s.getChildAt(1) (where s is the instance of the Slider component). Then you can easily change its properties like Width, Height, etc.

Here is the list of the styles that can be used for skinning a Slider component:

Slider component styles

sliderTrackDisabledSkin

sliderTrackSkin

thumbDisabledSkin

thumbDownSkin

thumbOverSkin

thumbUpSkin

tickSkin

As you can see in the flash demo below, in Flash player 10 the  left image has strange artifacts while in the right image there are no artifacts.

I used Alpha: 99% for the Movie clip with the PNG and the artifacts were gone. I’m not sure what causes the artifacts in FP10 and if this solution is the right one, but it worked for me.

Here is the demo flash:

(Please open the article to see the flash file or player.)

This is the code that I use for scaling:

var testTxt:TextField = btn.getChildByName("labelTxt") as
TextField;
testTxt.autoSize = TextFieldAutoSize.LEFT;
testTxt.text = "SCALE SPRITE+TXT";
testTxt.x = 4;
 
var bg:Sprite = btn.getChildByName("bg") as Sprite;
bg.width = testTxt.width + 8;
 
var orig:Sprite = new Test();
var txt:TextField = orig.getChildByName("labelTxt") as TextField;
txt.autoSize = TextFieldAutoSize.LEFT;
txt.text = "SCALE SPRITE+TXT";
txt.x = 4;
var bg2:Sprite = orig.getChildByName("bg") as Sprite;
bg2.width = txt.width + 8;
orig.x = btn.x;
orig.y = btn.y + btn.height + 4;
 
addChild(orig);
 
btn.scaleX = 100/btn.width;

And THE SOLUTION is to use GridFitType.NONE for the gridFitType property of the TextField. The default value of the gridFitType property is GridFitType.PIXEL, which forces the text field to position according to the grid.

1. the name of the style and
2. your class that you want to use as the skin.

Here is the list of the styles that can be used for skinning a component:

ComboBox component styles

cellRenderer

disabledSkin

downArrowDisabledSkin

downArrowDownSkin

downArrowOverSkin

downArrowUpSkin

downSkin

thumbArrowUpSkin

thumbDisabledSkin

thumbDownSkin

thumbIcon

thumbOverSkin

trackDisabledSkin

trackDownSkin

trackUpSkin

upArrowDisabledSkin

upArrowOverSkin

upArrowUpSkin

upSkin

Information for any of the above styles of the ComboBox component can be found in the Flash Help for the ComboBox class.

The code for skinning is:

myComboBox.setStyle("upArrowUpSkin", CustomUpArrowUpSkin);

Where CustomUpArowUpSkin is the class of your custom upArrow skin for Up state of the up arrow button.

How to toggle button with two states in two lines of code,i.e. sound on/off button?

Let’s say you have a movieclip called “sound_btn” with two frames for the two states – sound on and sound off. Here is the code:

sound_btn.onRelease = function(){
 
this.gotoAndStop(Number(soundIsOn)+1);
 
soundIsOn = !soundIsOn;
 
}

The code soundIsOn = !soundIsOn; is equal to:

if(soundIsOn){
 
soundIsOn = false;
 
}else{
 
soundIsOn = true;
 
}

And the line this.gotoAndStop(Number(soundIsOn)+1); sends the movie clip to a frame number depending on the value of the Boolean variable soundIsOn. Number(soundIsOn) = 1 if soundIsOn = true, and Number(soundIsOn) = 0 if soundIsOn = false.

Hello,
…..

Unfortunately there is a bug filed against the use of the stopAllSounds()and the FLVPlayback component. The stopAllSounds method breaks the play/pause button in FLVPlayback component.

The bug is currently deferred, so I can’t give you a potential fix date for this.

Chris Bedford

But I found a workaround using instanceof and checking if the object is instanceof Sound or instanceof FLVPlayback and then I call the Sound object’s stop() or the FLVPlayback component’s stop().

This is not very professional solution, but when I found a better one I’ll post it here.

BG version ——————

Ето какво ми отговориха на и-мейла от Adobe по повод на този проблем:

Здравейте,
…..

За съжаление има регистриран проблем за използването на stopAllSounds() с FLVPlayback компонента. Методът stopAllSounds “разбива” play/pause бутона на FLVPlayback компонента.

За момента решението на този проблем е отложено, затова не мога да ви дам конкретна дата за решаване на проблема.

Поздрави,
Крис Бедфорд

Аз обаче намерих един начин да заобиколя този проблем като ползвам instanceof и проверявам дали обекта е instanceof Sound или instanceof FLVPlayback и им давам едно stop(). Това е малко тромаво решение, но за момента не се сещам за нещо по-добро.
