ActionScript 2.0 :: Cacheasbitmap Bug Cs3 / Flash Player 9?
Aug 19, 2009
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.
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.
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.
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:
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.
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?
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.
Flash 8 compiled ActionScript AS2 ... combination of Classes and FLA embedded code
My loader component works when I publish to Flash Player 7 but not when I publish to Flash Player 8, why? The publish setting are for ActionScript 2.0 on both.
I am trying to create a flash player to display images in sequence using Flash player & ActionScript. The code below has lots of errors and I can't work them out. I have programmed in other languages and am perfectly aware that something like this.
*code*var imageLoader:Loader;imageLoader = new Loader(); // 1120: Access to undefined property imageLoader*/code* OR*code*var imageLoader:Loader = new Loader(); // 1046: Type was not found or was not a compile-time: Loder*/code*
I have a swc plugin embedded in my product to stream live video to a group of recipients.The plugin uses the NetStream, NetGroup and NetConnection objects, the server I use to handle the RTMFP session is Influxis.One client creates a group as a publisher, and stream a live video.His Camera is enabled and I can see the video on the screen as well. The others connect to his group and play the video.Peer assisted Networking is enabled for both the publisher and the recipients.The plugin worked well in all 10.x versions (10.1/10.2/10.3)However, when upgrading to flash player 11.x, it stopped working.
-11.x to 11.x isn't working. -10.x with 11.x isn't working. -only 10.x to 10.x is working.
The server I use to handle the RTMFP protocol is Influxis.com I sent them the same question as well.The weirdest fact is that I'm using flash builder 4.6 with 4.6 sdk, which is aimed for flash player 11.1, and it is only working with 10.x flash players.
I'm having a performance problem that seem to be related to Flash Player 11.I noticed this mainly because Chrome auto-updates the flash player. So, it's now up to 11 in Chrome. During a sliding section transition, the flash player chokes and skips about 10-20 frames. In essence the content jumps, not a smooth transitions. You can see this at the following url. Using a browser with 10, plays as intended, a separate browser with 11, chokes and jumps ahead.
firstworldproblems-[url].....I have security sensitive site, that is more elaborate that I can't share here. But, the same issue is happening above.I'm using LoaderMax to load assets. Adding it to the stage and then animating them in from the left or right of the stage, using Tweenmax. The one I can't show is a series of images, 1280x640 pixels, 10 in total.Removing items from the stage when they are not visible, so I can get the CPU usage back. On Flash Player 10, this is working as intended.On 11 it jumps. I don't think it's the removing assets from the stage that's choking the player, because the above link has the same issue.I feel like this is a Flash Player 11 performance issue.
In some cases, such as what my client wants - Flash 6 and Flash 7 players behave slightly differently... a very annoying thing at times.Now, what I need to be able to do is to detect what version of Flash Player the user has. This will be done while my flash application is playing and then run the appropriate part of the function I am writing.Any way to detect what version of Flash Player is running from within the Flash Player?
I have two mp4 video files on webserver, i wanted to play them in flash player(flv player) on my asp.net page, but i couldn't be able to play them, i also tried to play them in quick time player the same prob occured. but i waz giving the accurate path, there were no spaces in mp4 file names etc. Does it need to have mp4 player(or codec etc) installed on webserver?
I have also some wmv files on that server , and i am playing perfectly using silver light player, and media player object on my website.
I am trying to make the SIMPLEST POSSIBLE MP# player using the player component preinstalled in flash.It is very simple, the code is as follows:
Code: on (release) { player.contentPath ="Song.mp3" player.play() } ("player" is the mp3 component)
This works if I want a single track to be selected and played.Now, I need it to AUTOMATICALLY LOAD THE NEXT TRACK, which I will input in the code.I am thinking something like this:
So, you have a sprite, you draw some graphics, you set cacheasbitmap=true... I can't seem to access the newly created bitmap data, to access the dispose() method.
I have a slight problem when publishing to Flash Player 7 but works perfectly in Flash Player 6, below is the code:[code]In short this creates a list where the values are kept in SharedObject.I need to use a WebService so I require Flash Player 7, as I said this works as expected in Flash Player 6, so maybe someone may know a pitfall or two when migrating code form 6 to 7?
I am trying to put together a simple game and have been doing really well until I decided I am going to have to create a new class to handle enemies.What I have so far is a player walking around on random terrains and I am up to the point where I have placed x amount of enemies on stage at appropriate times. I have written their class which will hopefully eventually handle their behavior and it outputs simple trace("BOO!").
Where I face the problem is that I obviously would like to make these enemies follow the player to attack. But when I try to access the .x or .y attributes of the player, it throws an error: 'call to a possibly undefined property with static type Class'?I have tried accessing the .x using the following ways (where badger is my player instance and Main is my class definition within the properties of the FLA):
Main.badger.x Main(root).badger.x Stage.badger.x
I have also tried to access other vars and still nope..My class code is this:
