Well I will do as Glen suggested, the first option. In my custom class that implements an IModuleConteiner interface, I will add a get fixedHeight():Number function.

Re: [Flashcoders] ScrollRect and masking
You should possibly roll your own class which is the list + mask that
reports it's height and width as that of the mask.
Alternatively, if you are feeling lazy, make the mask a symbol give it
an instance name in the IDE, or do it programmatically and access the
width / height of that in your calculations, e.g.
currentModule.x = (stage.stageWidth * 0.5) - (currentModule.myMask.width *0.5)

[Flashcoders] scrollRect....bad idea?
Last night I learned about how cool scrollRect is. It made things a lot simpler, and faster, for basic rectangular masking. I was pretty stoked. So stoked that I decided to replace my mask within my BaseComponent class with a scrollRect. This worked ok for a bit, until I used a class that drew directly into BaseComponent, and got flash to consistently blow up in my face: http://newmedia.cdws.ucf.edu/b2evolution/index.php?blog=6title=scrollrect_mystery_crashmore=1c=1tb=1pb=1 Thankfully this smart guy has already dealt with it. I went and retrofitted my classes to not draw into the root of BaseComponent, and things no longer crashfor now. So my question is: Do you use scrollRect? Does it work for you? Do you have to constantly be careful of this problem, or do you just not use scrollRect and live with the performance hit?

}
The movieclip bg contains only a jpg 635x540.
The movement is pretty jumpy. Should I be using BitmapData instead?
I'm a bit lost! I've been searching for code samples online for the past 2
hours and
I haven't found anything useful.
Does anyone have a useful link for parallax or tile-based games using
Flash
8 features?
Performance is the key issue here, since this is going for a very big and
complex game
and I want to optimize it as much as possible.
Thanks a lot!

Re: [FlashCoders] scrollRect
BitmapSprites extend Bitmap. Bitmap is an internal class, and extends
DisplayObject. DisplayObjects' have a drawing index, just like MovieClips
do. So, instead of swapDepths, you'd use setChildIndex.
Now, for individual bitmaps that you are drawing, addToBitmapSprite, they
are added to the internal array, and drawn in that order. It would be
probably 10 minutes to add that method and call redraw to allow bitmaps to
change depth.
...or you could do it; I can give you Suversion access to the source if you
wish.
Alpha is handled by your bitmap. Bitmaps support alpha channels, so
whatever bitmap you added should have the alpha. In my case, the moving
sprites example uses a circular PNG, and since PNG's have alpha channels,
Flash draws the circle correctly on top of other circles.
MovieClip's have gotten more powerful in Flash Player 8.5, yes, mainly
because of the DisplayList which seperates a MovieClip from existing from
actually being rendered/drawn each frame. It is not, however, re-inventing
the wheel. We have not been able to blit in the Flash Player until version
8; instead, we've had to duplicate a tile 100 times vs. drawing onto 1
bitmap.
Great example of why blitting is so powerful and scaleable:
http://www.gskinner.com/blog/archives/2005/08/flash_8_thought.html
Significantly less process, less RAM, and scales to infinite bitmaps.
I have no benchmarks nor numbers other than creating 100 MovieClips in Flash
8 used 99%CPU, and 60 megs of RAM, and the framerate sucked. Changing those
100 MovieClips to be 1 bitmap, and scrolled via a copyPixels from a
double-buffering used 6% CPU and full framerate. That's what made me write
Diesel.
When you start adding BitmapSprites, you are adding overhead however because
they themselves are DisplayObjects, like MovieClips, only they are drawn
into 1 bitmap vs. 30 of them drawn in 30 places in the DisplayList.
The hybrid approach is to use 1 Bitmap, load all of your tiles and draw to
just 1. You're actual monsters and characters that move, make Sprites (or
MovieClips), and remove them from the DisplayList if they are not on-screen.
Use scrollRect for the area you are scrolling, and use double-buffering
(copyPixels from a rectangle from an off-screen bitmap).
This doesn't scale well because Sprites have more overhead, and moving them
is sometimes more expensive then copyPixels, but it works well enough in the
alpha, so I'm sure beta, and release it'll still be smokin'.

Hi Jester,
Thanks for the url. It seems very interesting.
There is one thing that bothers me, aside the fact that
I'would have to re-write a lot of stuff from scratch, if I
used a model like this.
How do you know in what depth to draw everything?
How do you handle _alphas?
The movieclip model provides a very easy way to stack
images one above another with no problems. It just seems
a lot of work, it's like re-inveting the wheel.
How much can performance benefit from an approach
like this? Any benchmarks, numbers?
Is there a hybrid approach maybe? One that requires
less code but increases performance?
Thanks!
Dimitrios

Subject: [FlashCoders] scrollRect
Hi all,
I'm trying to make a very basic prototype to test parallax movement with
Flash 8.
Is movieclip.scrollRect what I should be using? I tried this:
var bg:MovieClip = _root.attachMovie(bg, bg, 2);
var y:Number = 0;
_root.onEnterFrame = function():Void {
bg.scrollRect = {x:0, y:y--, width:635, height:540};
}
The movieclip bg contains only a jpg 635x540.
The movement is pretty jumpy. Should I be using BitmapData instead?
I'm a bit lost! I've been searching for code samples online for the past 2
hours and
I haven't found anything useful.
Does anyone have a useful link for parallax or tile-based games using
Flash
8 features?
Performance is the key issue here, since this is going for a very big and
complex game
and I want to optimize it as much as possible.
Thanks a lot!

RE: [FlashCoders] scrollRect
You want to use bitmap caching in combination with scrollRect.
Use movieclip.cacheAsBitmap = true
Also any bitmaps you use should be smoothed. So make sure your jpg is
set to allow smoothing in the library. If you are dynamically loading
jpg's read this. If not read it anyway :)

Good Luck.

Re: [FlashCoders] scrollRect
JesterXL,
I'd be interested in see this engine running but the demos on your site seem
not to work anymore with the latest Flash 8.5 alpha player.
If I import the project into Flex Builder and try to run it , it tells me
that some errors exist but it doesn't show me where the errors are.
Would be cool to get a hint on this to compile it with the latest Flex beta
to make it run.
Thanks,
Sascha

Re: [FlashCoders] scrollRect
Ah, the joy of alpha software... sorry about that.
:: goes to fix ::
Remind me to do this again when Flex 2 is released. There is a bug with
flash.display.Loader, and Adobe is already aware of it (Tile Loader will
load every other image). Additionally, the html-template is not included
(Subversion is being a bitch), so when you get the error in Flex Builder 2,
just right click on the error and Rebuild html-template
Other than that, she actually works a tad faster and uses less RAM with the
beta.
