Where is the mistake?

[Guest]

Hi

I keep getting an error when following the step by step instructions in the Adobe Press book "actionscript 3.0....flash pro CS5" classroom in a book, chapter 3, pg 59

It says:

"Scene 1, Layer 'actions', Frame 1, Line 72    1120: Access of undefined property None."

and the line it is refering to looks like this:

var tweenFadeOut:Tween = new Tween(instrument, "alpha", None.easeOut, 1, 0, 3, true);

What am I missing here?

import fl.transitions.easing.None;

The entire code looks like this:

import flash.events.MouseEvent;
import flash.events.Event;
import flash.display.MovieClip;

star_mc.addEventListener(MouseEvent.CLICK, rotateStar);
function rotateStar(e:MouseEvent):void {
    star_mc.rotation +=5;
}
addEventListener(Event.ENTER_FRAME, starMove)
function starMove(e:Event):void {
    if (star_mc.x < stage.stageWidth) {
        star_mc.x += 2;
} else {
    star_mc.x = 0;
}
}

var instrument:MovieClip = banjo;
import flash.display.MovieClip;
import fl.transitions.Tween;

instrument_txt.text = "Banjo Baby!"

violin.addEventListener(MouseEvent.CLICK, onViolin);
banjo.addEventListener(MouseEvent.CLICK, onBanjo);
trumpet.addEventListener(MouseEvent.CLICK, onTrumpet);
glock.addEventListener(MouseEvent.CLICK, onGlock);

function onViolin(e:MouseEvent):void {
    instrument = violin
    instrument_txt.text = "Violin Baby";
}
function onBanjo(e:MouseEvent):void {
    instrument = banjo
    instrument_txt.text = "Banjo Baby";
}
function onTrumpet(e:MouseEvent):void {
    instrument = trumpet
    instrument_txt.text = "Trumpet Baby";
}
function onGlock(e:MouseEvent):void {
    instrument = glock
    instrument_txt.text = "Glock Baby";
}

grow_btn.addEventListener(MouseEvent.CLICK, grow);
shrink_btn.addEventListener(MouseEvent.CLICK, shrink);
rotate_btn.addEventListener(MouseEvent.CLICK, rotate);
hide_btn.addEventListener(MouseEvent.CLICK, hideClip);
show_btn.addEventListener(MouseEvent.CLICK, showClip);
fadeOut_btn.addEventListener(MouseEvent.CLICK, fadeOut);
fadeIn_btn.addEventListener(MouseEvent.CLICK, fadeIn);

function grow(e:MouseEvent):void {
    instrument.scaleX += .1
    instrument.scaleY += .1;
}
function shrink(e:MouseEvent):void {
    instrument.scaleX -= .1
    instrument.scaleY -= .1;
}
function rotate(e:MouseEvent):void {
    instrument.rotation += 5;
}
function hideClip(e:MouseEvent):void {
    instrument.visible = false;
}
function showClip(e:MouseEvent):void {
    instrument.visible = true;
}
function fadeOut(e:MouseEvent):void {
    var tweenFadeOut:Tween = new Tween(instrument, "alpha", None.easeOut, 1, 0, 3, true);
}
function fadeIn(e:MouseEvent):void {
    instrument.alpha = 1;
}

Go all the way to the bottom of the page, you need to add in the transition.easing classes. Then it should work as expected.

Thanks,

I see importing the "fl.transitions.easing.None;" does the job.

How can I import all easing classes, or cant I?

Scuze the simple questions, but this is all very new to me.

[Guest]

that should work:

import fl.transitions.easing.*;

[Guest]

It does indeed, thanks

In the book it says that CS5 can do automatic insertion of import statements...

Do you know where to set this preference?

[Kenneth Kawamoto]

Just type in, say "no", and then cmd + space (which is on Mac; use whatever the equivalent on PC - ctrl + space?). You should get a list of classes/functions/variables begin with "no". "None" will be one of them. Select it and return.

This is the behaviour Flash IDE copied from Eclipse (Flex/Flash Builder).
