Professional :: Internal Workings Of Bitmap Caching?
Aug 28, 20111. I've read that when Bitmap Caching an object, if the objects you are caching are bitmaps that all point to the same bitmapData object, than only one instance is cached and used by the GPU. However, if the bitmap contains a scale, does this hold true, or is a new bitmap cached for each object because of the new scale? I'm pretty sure its the second one, just checking.
2. When using cacheAsBitmapMatrix, I've seen examples setting the matrix to identity, and setting it to the concatenated matrix of the bitmap object. Can someone explain the difference between the two approaches? I would assume setting it to identity doesn't scale it up or down when caching is as stated in the documentation:
"The matrix transformation you apply to the cacheAsBitmapMatrix property is applied to the display object as it isrendered into the bitmap cache. Thus, if the transform contains a 2x scale, the bitmap rendering is twice the size of thevector rendering. The renderer applies the inverse transformation to the cached bitmap so that the final display looks the same."
But if this bitmap is nested in a sprite that moves throughout the scene, will the bitmap still move with it? Or will I need to update the matrix's x/y everytime I update the sprite's x/y. If this problem exists, does using the concatenated matrix get around it.
3. Finally, I have seen some sites state that more gpu memory is used when cacheAsBitmapMatrix (such as an additional copy of the texture being pushed into the gpu), but I was under the impression that this would just rotate and scale the texture in memory using openGL matrices. Why would more gpu memory be used when cacheAsBitmapMatrix is set?
My understanding is that when designing for mobile, if the graphic isn't too large, and the object doesn't contain nested animating objects, the best approach is to cacheAsBitmap and cacheAsBitmapMatrix on the object to ensure it won't be pushed to the gpu each frame, but feel free to correct me if I'm wrong. Adobe states "Always set the cacheAsBitmapMatrix property whenever you set cacheAsBitmap to true in content created for mobile devices."
Actionscript 3 :: Get Access To The Internal Bitmap Used By CacheAsBitmap?

ActionScript 3.0 :: Use The BitmapData Property Of A Bitmap And Pass It To The Constructor Of A New Bitmap Object?
Aug 20, 2009I know the topic of "duplicating" movieclips is a hot issue with the new virtual machine. Luckily, I understand the implications. I only am [currently] interested in duplicating a Bitmap. See, I load an image from an URL using 'flash.display.Loader.load', which is a non-blocking operation in Flash Player.However,I may use multiple copies of the loaded image (which is reported to be a Bitmap, naturally) in the display list at the same time.Hence, I naturally do not want to load the image from an URL every time, because I don't want to wait for a non-blocking call to complete. Nor do I need to - I mean one copy is already loaded, so it should be possible to just "duplicate" it, right?
My idea is to do use the bitmapData property of a Bitmap and pass it to the constructor of a new Bitmap object. I have not tried the following in action, but I want to hear whether any of you did and if the following would not work, what would:
Code:
var original_bitmap: Bitmap;
var copy_of_original_bitmap: Bitmap = new Bitmap(original_bitmap.bitmapData);
LiveDocs mention that the BitmapData being passed to a Bitmap constructor is "being referenced", which to me might suggest it cannot be used twice? There is also the BitmapData::clone() method, which I am not sure is applicable here or not.I know this is a lot of talk instead of just trying this out, but I test so much Flash Player code daily just to see "what works" (which should be documented instead by Adobe),

ActionScript 3.0 :: Object Creation Within Defined Area Only

I am starting with a circle for the moment, but I can't figure out how to set the range of object placement to that of an MC. I was planning on somehow calculating this out but I am stumped. Is there a better way for me to draw a shape, and somehow use a mask in as3 to define where the particles can no be placed?
View 21 RepliesActionScript 3.0 :: Skip The Creation Of A Data Object?
May 11, 2009I'm in the early stages of writing a rather complex app that grabs data from a database (via PHP bridge) and builds out content from it.This app is going to be a very visual timeline of sorts, with different entries of many types (images, audio, video, text, etc). Each entry type has some common properties (ID, location, date, etc), and some unique (imageURL for images, audioURL for audio, etc).When creating these objects dynamically, should I:
A) First read the data from the database, assign that data to a new object that contains *just* the data, and then pass that data object to the constructor of the visual representation of that object when instantiating the specific object of that type? Or,
B) Skip the creation of a data object, and instead pass the data property by property to the specific object class.
For instance (very roughly),
A)Code:
// receive queries data here
var newImageData:ImageData = new ImageData(imageURL, headlineText, captionText); // put data into data object
var newImageEntry:ImageEntry = newImageEntry(newImageData); // create new visual object, passing data object
B)Code:
// received queried data here
var newImageEntry:ImageEntry = new ImageEntry(imageURL, headlineText, captionText); // create new visual object directly
I won't be creating the visual representation of the object immediately, so I feel like I have no choice but to map the data to a data object first....but is there another way? Should I try to merge the two, so that an ImageEntry object can be created as the data is received, but then a separate call to that object would be required to actually create the visual representation of it when needed?In the past -- which apps quite a bit simpler -- I've simply mapped all the data during the XML parsing to dynamic objects that act only as containers for the data, which is then passed to a different object to create the visual representation of it...
ActionScript 2.0 :: Eval Methods - Dynamic Object Name Creation
Mar 9, 2009I'm having problems with my usual eval methods of creating objects to read off dynamic values programmatically using concatenation. I've found the set command doesn't seem to work with objects that are dynamic....
Code:
function createobject(item){
//create it and store something in it
set ("_root.item"+item.stored, "data storage test for item "+item);
}function checkobjects(){
for (i=1;i<5;i++){
checkit=eval("_root.item"+i);
trace("_root.item"+i+".stored="+checkit);
[Code] .....
Running this produces the output of...
Code:
_root.item1.stored=undefined
_root.item2.stored=undefined
_root.item3.stored=undefined
_root.item4.stored=undefined
How to do this - basically I'm trying to load data, then use that to create dynamic objects and values within it, then I'm trying to work with those values by again using loops to read off the dynamic values during runtime. Obviously if these were "fixed" variables, then it would be easy, problem is that its impossible to use the new Object() command with dynamic names!
Previously I've used this:
Code:
checkit=eval("_root.item"+i+".stored);
trace("value is "+checkit);
Is it my imagination, or was this stuff a lot easier to do in AS1?
ActionScript 2.0 :: Dynamic Creation Of Movieclip Class, Not Object?
Feb 7, 2005Is there another way to work with movieclip classes than attaching them from the library?For instance say that I have a textbox class that extends the movieclip class. Puts it on the scene and then I'm free to work with it from the class as I want.But inside this class I check if I need a scrollbar. If I do, then start a "sub-class" and create a scrollbar. I can have a movieclip in the library and attach it and have a new class on it. But what I want to do is write something like this
var clipScroll = createEmptyMovieClip("scrollBar", 3)
clipScroll = new com.texts.text_items.ScrollBar
the problem is if I do like this the class that I start is just an object. I can't trace where it is, I cant create a movieclip inside it and trace where that is.

Feb 16, 2011I'm trying to trace the path of an object by using setPixel on the object's position every frame in a BitmapData/Bitmap pairing. These pixels aren't showing up normally and I suspect I have a fundamental misunderstanding of the BitmapData class. Here's what I'm doing:

public var contrail:Bitmap;
private var contrailColor:uint;[code].....
Using this code, the red pixels don't show up. If I initialize contrailBase to 0xFF000000 instead then I get a black screen on which the red pixels DO draw, but I need the bitmap to be transparent except for the contrail. What am I doing wrong?

View 1 RepliesActionScript 3.0 :: Display Objects Drawn To Bitmap Always Dispatches Rollover / Rollout
Apr 12, 2009If you draw a movieclip (with a 3d rotation on it) to bitmap, eventlisteners will always dispatch rollout and rollover for that movieclip (on mouse over). A solution could be to set the matrix3d = null ,draw, and then apply the original matrix3d, but I can't do this in my project 'cause all clips is a 3d object to a parent 3d object that gets drawn to a bitmap every frame.
To see the bug, copy this example code into the first frame on the stage (CS4 flashplayer 10).

ActionScript 3.0 :: Display 1 Display Object Many Times?
Aug 14, 2009Can you make one Bitmap Object (I'm using an external jpg) or something similar, and then display it many times simultaneously without creating a separate object each time?
Also, would they be easily removed or hidden?
I've got a little checkmark jpg graphic loaded here, but I'm not sure how to go about using it in many places at once.. I can only display it in the one place at any one time...
I'm thinking there might be a way to load the picture once, then use its bitmapData elsewhere in new display objects somehow, without needing to reload the image over and over?
