ActionScript 2.0 :: CacheAsBitmap + Mask, Bizzarre Behavior?
Mar 3, 2010
In the root of my swf i have 2 mc files "menu" and "mask". Mask has inside a vector gradient, while menu is a vertical scroll-able menu, then the mask makes a fading effect on top/bottom. The code:
Code:
stop();
_root.menu_mask.cacheAsBitmap = true;
_root.menu.cacheAsBitmap = true;
_root.menu.setMask (menu_mask);
Inside the menu i have, on first frame, the code for scrolling ( and some functions cause the buttons are duplicated from info on a xml file). The code:
Code:
stop();
var yPos = -23;[code].......
The Problem: If i Scroll the buttons all way up, the mask transparency parts looks like to move right (not the whole mask, just the transparency points). If i set no transparency for the mask, this problem doesn't show up.

when cacheAsBitmap is true, do x and y suddenly become ints? im ok with them being drawn this way, but my calculations require x and y to be numbers, because else strange behaviour occurs, which is happening now.

Why does hitTestPoint isn't working on DisplayObjects that has cacheAsBitmap set to true?It does work, but it takes the Whole rectangle of Display object, not respecting wheather or not pixel is transparent or not (transparent pixels return true after hiTestPoint)

Is there any way to add 3D properties like .z and .rotationY without the MovieClip's cacheAsBitmap property being automatically set to true? This automatic cacheAsBitmap to true messes up the visual of my MC (which is using a lot of bitmaps and filters) as soon as I rotate it in 3D. And turning it "off" right after it doesn't seem to work.

Start a fresh AS2 document using its default publish settings. Draw a circle on the stage and convert it to a movieclip. Name it for example "my_mc". Apply a motion tween to it from left of the stage on frame 1 to right of the stage on frame 20. Test it and the circle moves from left to right.
Now apply this code on frame 1:
code: my_mc.cacheAsBitmap=true;
Test it again: the circle doesn't move; it freezes on its left position of frame 1.
Now change the publish settings from 'flash player 9' to 'flash player 8'. The motion tween now works again
Is this some bug anyone is aware of? Why can't I apply cacheAsBitmap AND a motion tween on a movieclip when using a AS2 document and Flash Player 9?
Just open attached file. While on its flash player 9 setting the circle doesn't move. Change the setting to flash player 8 and it moves again.

I'm loading child swfs in main swf, but as default all loaded swfs has cacheAsBitmap set to true, how to set it to false from main swf? this: loadedSwf.cacheAsBitmap = false; - have no effect.

I'm loading a MovieClip which pixels should be displayed perfectly.Every child of this MovieClip and the MovieClip itself uses only whole integers in position and size.The funny thing is that even if I use "myMovieClip.cacheAsBitmap = true" sometimes it will appear blurry.

CacheAsBitmap stores a raster copy of a movieclip in memory to use. If that movieclip is rotated or scaled, the performance gain is lost as it must re-cache the new movieclip. I assume this also applies to a movieclip that has a constantly repeating internal timeline, even if that movieclip isn't rotating or being scaled. However, do additional frames (that aren't being used) affect this?I have a 'player' movieclip. This movieclip consists of about ten frames, each its own animation. Idle stance, walking, jumping, all the standard stuff. THe movieclip remains stopped on frame 1 (idle stance) for most of the game. Right now the Idle stance is an animation, so to use cacheAsBitmap I need to stop the idle animation. That's fine, but does the additional content in the movieclip interfere with this? If I go from a walking animation back to the idle stance will it re-cache the idle stance for me?
The main reason I ask is that I wasn't able to notice much of a performance difference between either method. Cacheasbitmap on a player sprite with animated idle stance, and Cacheasbitmap on a player sprite with a static idle stance. Both resulted in 39 fps (set to 40) in the flash player. Which is good I suppose, but I don't know how the results will vary for someone with a slow computerThis is an important area of the game because at any given time there could be up to 12 player sprites on the screen (all with filters attached to them). So if one player is moving left/right the other 11 must be re-translated on each frame (since the stage moves too) so if all 11 players are playing their idle animations, with a glow filter, WHILE flash tries to re-cache all of them, that could lead to performance issues (although it hasn't yet for me)I want to give players the option to disable the idle animation, I just hope that it's actually working the way I intend. If cacheasbitmap fails because of any other content inside the movieclip then this would be a useless feature.

I'm actually rendering quite a complex 3D scene (complex is a relative term here, doing a similar scene in d3d or opengl would be a breeze, but they're hardware accelerated so you'd expect that). I've built a 3D engine with some basic features including depth sorting, 3D tweening, and mapping between polar and cartesian coordinates. This last bit should be a give away as to what I'm doing - I'm rendering a 2d grid onto a sphere that I then unravel, spin around, squash, expand all so the Client goes ooh and aah. The trouble, is that on anything other than my workstation, rendering crawls. From discussions with other flash programmers and my own investigations, the slow down is most definitely caused by the rendering itself, and not my relatively swift matrix and sorting calculations (they take around 5-14ms tops depending on the complexity of the scene) .
So, my question is, what exactly does happen when I set cacheAsBitmap to true on a display object? I see no texture map distortion so I'm under the impression that flash automatically splits the cached bitmap into polygons for rendering, but how good is flash at doing this? I don't care about texture distortion on objects beyond a certain z value because they're far away, and try as I might I have found no way of setting the equivalent of a display objects 3d render quality. I'm certain that if I could set such a value, I'd at least double the render speed of my scene by only rendering many polys for objects near the camera. Failing this, is there a way to coerce flash into rendering a low poly object? Perhaps by making invisible any graphically complex children?

I'm using cacheAsBitmap to create a gradient mask. The code I set up worked great and all was well but I soon discovered problems when cacheAsBitmap was being nullified when its parent mc was loaded into another mc. I read up on it and from what I understand, since I'm using the MovieClipLoader class, this code should be included in onLoadInit in the root mc (start_mc). Basically this is what I have: start_mc loads main_mc (target) and rollMask1 and roll1 are contained within main_mc. Here's the script for onLoadInit:

is it possible to get access to Flash's internal bitmap cache of an object when CacheAsBitmap is on ?
eg, something like:
var bmd:BitmapData = someDisplayObject.getCachedBitmapData();
if (bmd != null)
trace("stoked!");
else
trace("bummer. got to bmd.Draw(someDisplayObject) ourselves.");

in order to increase performance of a scrollRect i must cache the vector as a bitmap, otherwise the scrollRect will be simply a less performant mask (info source).however, i can't seem to move an object/scrollRect once i've applied cacheAsBitmap. why?

I'm a seasoned AS3 developer working on a major online project and we've run across a strange visual anomaly which is connected to the movieclip cacheAsBitmap property. When using author-time additive blends (which we use for lighting effects) in a movieclip, turning on the cacheAsBitmap property (without which performance becomes unacceptable in our very detailed art) seems to 'destroy' the additive blend. The art director says that the visual effect produced is as if the blend mode had been set to Normal, which I can confirm--some blends which are yellow turn orange, other 'spotlights' turn from transparent yellow to dark gray.

The cacheAsBitmap property is somewhat similar to what I had to do to get the filters to show up on iPhone GPU mode:But I played around with that property yet filters still don't show up.I even tried to put child objects (with filters) inside a parent object (no filters but cacheAsBitmap = true), no shows.

I have a very complex vector symbol on the Stage - background_mc. I have set background_mc.cacheAsBitmap = true.This turns background to bitmap and makes Stage repaint fast.Every frame the background light changes.I use the following code to alter the light.
(new Color(background_mc)).setTransform(light);
And here is the problem.The code works very slow.I guess because the light is applied to the contents of the background_mc.And then a new cached bitmap is resterized once again.The same code over BitmapData of the same size works much faster!Is there a way to tell Flash to apply color-transformation to the cached bitmap, instead of underlying vector symbols?
Note, that background_mc is scaled when Stage is resized.This is not so fast, but it's good, because the picture quality preserved.If I convert background_mc to BitmapData, bitmap would be scaled.

I have an image converted into MovieClip (background) and I have a mask MovieClip (bgMask) set to mask the image MovieClip like this:
[Code]....
In bgMask I have a few linear gradient shapes which I animate with shape tweens using keyframes. If I don't set cacheAsBitmap for both, nothing will happen since what I need is alpha masking and it will work only then. In this scenario is cacheAsBitmap working for me or agains me? (not that I have any choice). Still I could try to replace some of the shape tweens with MovieClips with solid shape in them and just move them around to uncover some part of the background, and where I want a smoother transition I would stick to the shape tweens. If the object that I've set cacheAsBitmap true to is no longer being animated moved sized and so on, would it be better to set cacheAsBitmap to it to false?

I've recently started using the cache as bitmap switch on my on-stage movieclips, to great success, while creating my isometric RPG. What I can't grasp though, is how to apply it to AS-instantiated classes/object.How can I turn on cacheAsBitmap inside a class that extends movieclip? Alternatively, how can I do it from outside the class, from another class that adds mentioned movieclip to the stage?

I have a startDrag function set up on a loader and mask that when the mouse is down on the loader it drags, when not it doesn't. There is also 2 buttons that control whether mask1 or mask2 is used. What i would like however is when the mouse is down - the area of the loader outside of the mask is visible but only by about 10/20% alpha, that way the user can see where all the image is while dragging. Is this possible? Full code can be seen below and i have attached the zip with the .fla file:

My webapp progressively slows down over 45 min of use. People will be using it for longer, and it needs maintain its snappiness.I'm making sure to dump() any Bitmaps I use and of course clear any intervals that are running, but for some reason there's a buildup over time, and only restarting the browser clears up the lag, for example, when the user is entering text.I'm going to go ahead that it's an error in how I'm building things and not a Flash memory leak
Question 1: I read somewhere that every time that I "cacheAsBitmap," the movieclip must explicitly be set to cacheAsBitmap = false, or else the memory won't be freed up, in the same way that Bitmaps must be dump()ed to free up memory.I'm assuming I need to only do this for MCs that I cacheAsBitmap by code, and not through the GUI. Do I need set cacheAsBitmap = false via code even for MovieClips that I check off with "use runtime bitmap caching" through the Flash GUI?
Question 2: When I have added filters (like a DropShadowFilter) to the filter array of a movieClip, do I need to do anything to free up that memory, such as delete the references to the filters, or set filters to a blank array, before the MovieClip is removed... or is this done automatically? I have been assuming that it is handled by flash, but this could be a HORRIBLE assumption.

what i am doing is to make something along the lines of the "scriptable mask" tutorial Inigo was kind enough to put up.My idea is to have a large mask behind the whole of my flash site, this masks a colour image with a black & white one (nothing tricky). The image I am using is actually 5 separate images combined, and each is a pic of certain parts of the site.I also have a very basic set of buttons along the bottom... each corresponding to each section.
All I want is to set it up so that when I mouse over the buttons, the _x of the mask moves to correspond with the correct image... really very basic... or so I thought .If anything it should be easier to do than what is in Inigo's tut (where he uses the _x of the mouse to move the mask)... i just cant seem to get it to work with a nice easing effect (its easy to get the mask to simply snap to each coordinate, but I need it to smoothly move).

maybe point me towards a better way to mask. png file is way too big. I have been using the mask layer option to create my own mask around a jpg image by drawing around it on the mask layer. There has to be a fetter and faster way to do this. Is it possible to maybe have a specific color range have an alpha value of 0. Similar to green screening whereas If I put the item I want to clip on a green background flash will auto take out the green for me. and by auto I mean action script maybe. I think this can be done but im not finding it.
how are these guys clipping these images [URL] they have the movie clips set up where the black background on the 3 layers of shoes is getting masked out. When I go into the shoe movie clips I see there is a black background but it just disappears when I go back to main timeline.

I just exported a FLA file as a quicktime movie in CS4 using the 'animation' setting, and it produced quirky results. A 'ghost' of each object was left on screen, apparently at the point where a keyframe was present in the original FLA file. Don't know how else to describe it, and I don't think there is a way for me to upload the movie for anyone here to see? Anyone experienced this? or know a way round it? I did manage to get it to play right when exported with the 'DVC PAL' type codecs, but the quality was awful. All the other options produced results at least as bad as the first attempt.

I would like to improove the behavior of my buttons in this way: i have 3 buttons (pix1, 2, 3)when you roll over each button the color is grey.how can i do to let the color grey when my mouse roll out off each button? for exemple I roll over on pix1 the color become grey and after I roll out of pix1. the color stay grey. It is just when I roll over on pix2 or pix3 that pix1 become back black and pix2 or pix3 become grey.for the moment it is like this : http:[url]......
I wrote this code: // size of the stagevar largeurScene:uint = stage.stageWidth;var hauteurScene:uint = stage.stageHeight;
//bt01 is a button called btserie01. I have juste written pix01var bt01:btserie01 = new btserie01();bt01.x = 90;bt01.y = 150;addChild(bt01);[code].........

I'd started a discussion about a problem with a SWF file not loading an XML data file when rendered in a .NET WebBrowser control in a different forum [url]
Further investigation has revealed that if the XML data file is loaded using Action Script 2 (via XML.load()), it works. But if the SWF file in question uses Action Script 3 (via URLLoader.load(), I think), the data file is NOT loaded, UNLESS the XML file is in the same folder as the HTML file.If either SWF file is loaded using Internet Explorer 9, then everything works OK. Are there any know issues (which would be apparently well-hidden from Internet search engines, because we've been beating on those) regarding the performance of SWF + Action Script 3 + .NET WebBrowser?
It's just so weird that there are ways to coerce the AS3 solution to work by moving files (not really an option for what we want to do), and that Internet Explorer 9 has no trouble, but the WebBrowser control (which everyone SAYS "is just a wrapper for IE") does NOT work the same way.
