RE: [Flashcoders] AS2: Tweening a very large vector file causes shaking
video card? how come? In my experience, if you don't have enough memory in your video card, and you send a lot of data to it, you can see things not render or not render properly.

[Flashcoders] AS2: Tweening a very large vector file causes shaking
Hi,
so this is a very odd problem, but I'm tweening an extremely large
vector file (about 4000x4000px), using the Fuse tween classes. Its
basically your standard slide across the surface of a massive object
from point to point effect, nothing fancy. But I'm having a bear of a
time getting it to animate smoothly. In particular, as it eases into
and out of tweens, I'm getting a weird jittering of the MC, so that it
stutters to a stop, like a car with bad brakes. The tweens themselves
are nothin fancy (see below). It seems like the problem started when I
added _rotation to the the mix. The file is vector, imported from AI.
is anyone familiar with this problem? Any recommendations for handling
this sort of basic (or so I thought) effect?
thanks,

mainpanel_mc.tween(_y,yPos,2.5,easeInOutSine);

Hi Matt,
Like the analogies :)
What tweening engine are you using?
If its your engine, there is a good speed comparison here:

If so, just change to a different engine, not every car is build to
move boulders ;)

Re: [Flashcoders] AS2: Tweening a very large vector file causes shaking
So as far as you know its caused by the combination of large file + rotation? Hmm, perhaps I'll try breaking it up into smaller MC's and then place those in a larger mc... .m On Fri, Mar 21, 2008 at 10:31 AM, Jon Bradley [EMAIL PROTECTED] wrote: On Mar 21, 2008, at 9:57 AM, Matt S. wrote: It seems like the problem started when I added _rotation to the the mix.

Re: [Flashcoders] AS2: Tweening a very large vector file causes shaking
That's a myth. If he's tweening one or two things the tweening engine
makes absolutely no difference. The only differences in terms of speed
between tweening engines is how each of they handle a massive number of
property updates on a massive number of objects. So there's absolutely
no problem using Fuse on that case, the problem's somewhere else. A
bottleneck problem isn't solved with a larger bottle.
All I can say about the problem is that it seems to be related to
rendering so yeah, you'll have to look into what you're doing. Use
cacheAsBitmap WHERE appropriate (not in the whole movieclip - it's too
big for that), use scrollRect when possible.
Remember, complex vector rendering is EXPENSIVE. So 4000px x 4000px is
nearly suicidal.
