Hi Everybody,

I’m new for AS3. I have some question about the classic tween vs AS3 Tweening.

I tried to compare the swf file size of both.

the first one i make an animation with the classic Tween.

the second one i make an animation with AS3 Tweening.

before, i thought the script tweening one will much smaller than the classic tween one, but after i compare both, the AS3 Tweening one has bigger file size.

So my question is,  
1.will the file size bigger if i use action script to move the object?

2.then what’s the advantage to tween the object using AS3 for a flash website?

3.how can I compress the filesize(i’m trying to build a full flash site)?
