Strange alpha

[Luigi Vercotti]

Hello

Do you have an idea why the array pics goes from alpha:0 to alpha:1 which I wish to work like that by the way. But I found out I have to code it opposite from 1 to 0. What am I missing, please?

 

TweenMax.allTo([boxesLight.boxesLightPic01,boxesLight.boxesLightPic02,boxesLight.boxesLightPic03,boxesLight.boxesLightPic04], 0, {alpha:1});

var timeline:TimelineLite = new TimelineLite();
var boxesLightPictures:Array=[boxesLight.boxesLightPic01,boxesLight.boxesLightPic02,boxesLight.boxesLightPic03,boxesLight.boxesLightPic04];
/*var i:Number=boxesLightPictures.length;
while (i--) {
timeline.insert(TweenMax.from(boxesLightPictures[i],2,{alpha:0}),i*0.1);
}*/

for (var i=0; i	timeline.insert(TweenMax.from(boxesLightPictures[i],3,{alpha:0}),i*0.1);
}

your code works as expected. doing the following may be more intuitive:

 

//set all boxes to have alpha of 0 immediately

TweenMax.allTo([boxesLight.boxesLightPic01,boxesLight.boxesLightPic02,boxesLight.boxesLightPic03,boxesLight.boxesLightPic04], 0, {alpha:0});

 

var timeline:TimelineLite = new TimelineLite();

var boxesLightPictures:Array=[boxesLight.boxesLightPic01,boxesLight.boxesLightPic02,boxesLight.boxesLightPic03,boxesLight.boxesLightPic04];

 

//tween all boxes to alpha 1

for (var i=0; i

timeline.insert(TweenMax.to(boxesLightPictures,3,{alpha:1}),i*0.1);

}

 

 

------------------

 

when using a from tween it is important that your objects that you are tweening appear in the state that you want the from tween to end.

so in the code you provided you were setting the alpha TO 1 so you could tween FROM 0.

 

 

in your code, if the boxes already had an alpha of 1, your first tween

 

TweenMax.allTo([boxesLight.boxesLightPic01,boxesLight.boxesLightPic02,boxesLight.boxesLightPic03,boxesLight.boxesLightPic04], 0, {alpha:1});

 

would be unnecessary

 

 

--------

 

my code tweens all obejcts TO alpha 0 and then Tweens them all TO alpha 1

if you need more clarity just let me know.

Thank you very much Carl

 

yes, yes...obviously I missed the "from to" now I understand where I was doing it wrong....
