ActionScript 3.0 :: First Bitmaps Start To Disappear?
Jul 22, 2009
I'm having an issue where after 24 bitmaps are placed inside a sprite, the first bitmaps start to disappear. When the last added Bitmaps get removed from the display list, the older ones start to reappear. Go here and check it out: http:[url].... draw 24 dots or whatever with the pencil tool (the only one that draws to a bitmap). You should notice that the 24th dot will cause the 1st one to disappear. Undoing (which simple removes the top bitmap/sprite) causes the 24th one to be removed (which is correct) but the 1st one also reappears which means its still there just not visible .Here are the relevant methods:
Code:
private function nextShape() : void {
newShape = new Sprite();
newShape.mouseEnabled = false;[code].....
I've imported 29 bitmaps into my library (gifs, each one 1728x1152, size ranges from 4-14kb, in each case the vast majority of the image is transparent). I add each one to the stage in the following manner:
var img1Data = new img1(1728,1152); var img1Map = new Bitmap(img1Data); containerMC.addChild(img1Map); // MovieClip to which all of the bitmaps are added
I'll try to be brief. I've built a teleprompter projector file app in Flash CS4 and it works great on PCs & MACs. Only one bug. the program works in three phases: Welcome & instruction screen / Text input screen / Prompter screen.Problem occurs when you first enter prompt screen
basic navigation and functionality includes:
BUTTONS: button to return to INPUT screen, a BEGIN button, a MIRROR text button, and a SAVE prompting position KEYBOARD: SPACE begin prompting, LEFT & RIGHT ARROW increase & decrease font size, UP & DOWN ARROW increase & decrease scrolling speed, HOME returns script to top, PAGE UP & PAGE DOWN moves script by 600 pixels.
MOUSE: MOUSE_WHEEL increases and decreases scrolling speed *(would like to add a ctrlKey modifier to change font size on mouse wheel - another day perhaps)
THE PROBLEM: When you enter the prompt screen and hit PAGE DOWN the script correctly moves down 600 pixels, but does not redraw on the stage. If you then hit PAGE UP it correctly moves up and the text is back on the stage. Hit PAGE DOWN again and it moves but does not render. You can repeat this continuously. I have a Y position reference that shows the Y coordinates of the text field, so I'm confident that the MC is correctly moving, it's just not rendering. If you hit PAGE DOWN and hit BEGIN the text renders in the correct place. Once you start the prompter, you can stop it and use PAGE DOWN and it renders correctly, but if you change the font size larger > 100 and hit PAGE DOWN the font again does not render. Again if you hit BEGIN the font renders correctly in the correct position.
WHAT I THINK: I've been trying to find a way to update or refresh the text field that is being manipulated on PAGE DOWN and font increase; no luck with updateAfterEvent or redraw. I've tried to start and stop the prompter programmatically in one frame at the end of the PAGE DOWN function & font increase.
POSSIBILITIES OR NEW STRATEGY? I'm a media production specialist with a school district in Florida, and I'm hoping to release this app to all our schools and to sourceforge.net. It's a small bug, but I'd rather not have to explain it if I can find a way to fix it. The following code block only contains the functions related to the navigation and prompter text box manipulation.
//Begin button toggle code.Toggle between begin and stop.startBtn.addEventListener(MouseEvent.MOUSE_OVER, startOver);function startOver(e:MouseEvent)[code].....
A Visual Basic & ASP.NET programmer I work with looked at the bug with me, and he believes the error is somehow related to the actual CLICK of the BEGIN button. As I noted earlier, we tried a workaround by using code to start and stop the prompter in one frame after the font size change, but that did not correct the issue. Yet when you physically click begin with the mouse it renders the text.What is it about clicking the mouse that causes the text box to render? Is it a focus issue? Like the keyboard has focus, but when you click BEGIN it returns focus to the text box and it redraws then?
I'm fairly new to AS3 and I'm trying to make a pretty complicated (for me) set of behaviors. You can see what I'm trying to do here: [URL]. The Main class sets up the crosshair, the navigation, the color bars that randomly roam the stage, and the 3 words that float around. The idea is that when you hover over a word, the color bars split apart like a curtain and two random pictures appear. Then, when you roll off the word, the pictures disappear and the color bars start roaming again.
I've got the color bars, the floating words, and the curtain split working great. My problem is bringing in the pictures. For whatever reason, 60 to 70% of the time the tween stops before it is complete. I think it has something to do with the fact that I've got a hover on a piece of text, and the mouse sometimes slips into the empty spaces between the letters, but even when I put a semi-transparent rectangle over the whole word to act as a hit area I got the same results. The ZIP with all my classes is here: [URL]. Again, I'm new to AS3 and OOP,
I'm trying to figure out the best way to compare a single bitmap against perhaps an array of saved bitmaps to see how close of a match it may be to any one of the bitmaps stored in the array. Right now I'm running a for loop that uses the bitmapData.compare() method to try to compare to see how much of a variance there is but... to be honest I'm at a loss as to how to use the resulting data to do so. Does anyone know of any good method to accomplish what I am trying to do? Forget looking at my code it's a waste of time because simply, it's not working.
i am making a quiz. My problem is that once the user completes the quiz and wants to start again the quiz is already on the last question. How do i make it so that once the user clicks start again the questions and answers arrays start from the beginning, sort of reset themselves.
I'm trying to broaden my horizons with it and so I'm trying to do an update of a quiz program my employer has. Everything has worked well, except for the timer. The button that starts the game has two options, "study" or "exam"; if the study is selected, there is no countdown, just the score keeper. If the exam option is selected, the timer is show (counting up). But, press "Start" and while the quiz begins, the timer, in either case, does not.
I'm going to post the actionscript for the timer that was already there, as well as the start button. I'm hoping someone can explain how this timer is supposed to work and why it's not; and where the disconnect lies in pressing the start button and making it run.The timer is embedded in a movie clip, with two dynamic text boxes, that are for some have no instance name; and actionscript spread out over several frames.Frame 1:
I have a movie clip that I add Bitmaps by using addChild(). I was wonding how would I go about displaying the next image that I added because as of now it is stuck on the first image.
I was wondering which method would be the most efficient (run faster)...Lets say I have multiple layering of animations, say a moving sky, then birds, then fireworks ordered respectively. Is better to have one bitmapdata (called BD) then do a copypixel of sky, then bird, then firework at every tick (I'm using a timer) and put it in one bitmap.
Or is it better to have 3 bitmaps (and put into 3 different sprites) with the animations separated, so when I update the birds I don't have to update the sky.share any knowledge on pros or cons of using multiple bitmaps vs using one bitmap in that situation. Aside for the increase of initial memory used.
I'm loading some external images and trying to get them to smooth, but for some reason it's not happening. i've been trying everything i can find on the internet over the past 10 hours or so, and nothing's worked.The code on my movieclip (first frame) is:
[code]...
my images are very high-res, so i know it isn't a resolution issue. anyway, they look crappy when they're sized down too. also, i'm pretty sure smoothing is the issue, because i have a very similar image in the library (a detail from the same shot, and similar resolution, etc.), and it looks great when i allow smoothing in the bitmap properties panel.
I have a Bitmap where I can draw on. After some seconds I want to let the drawing fade away and blend over to the original picture/bitmap. Can I do this with the blend mode by drawing the original bitmap on it? I tried something like this and of course it isn't right. Just copying the alpha channel if I get the documentation right.
dstBitmapData.draw(srcBitmap,null,null,BlendMode.ALPHA,null) dstBitmap = new Bitmap(dstBitmapData);
I want to put some percentage to the destination bitmap. So that after doing this some frames the original picture will be visible. As the user can interrupt this by start drawing again I want to use the BitmapData object dstBitmapData.
I wish to add some 3D bitmaps to my 2D game. Everything is currently drawn via copypixels into the only movieclip and that is rendered. Am I correct in that I need to create (for example) a sprite, add a bitmap to it, perform all my 3d transformations and then simply .draw the result into my bitmap? If so are there any simple examples of doing so, also what about camera, focal length, perspective etc. etc. Are they taken into account before the .draw?
I have a jpeg that I have exported to actionscript via the library. The jpeg class is "adcouncil". If I want to add it to the stage I would use the following code:
Code: var adcouncil = new adcouncil1(150,150); var myImage:Bitmap = new Bitmap(adcouncil) printMC.addChild(myImage);
The problem is that I want to ad these Bitmaps to the stage dynamically. My first instinct is:
Code: var adcouncil = new this["adcouncil1"](150,150); var myImage:Bitmap = new Bitmap(adcouncil) printMC.addChild(myImage);
Trying to add EventListeners to Bitmaps.Can I add an EventListener directly to a bitmap?If I load an image to a UILoader then addEventListener to the UILoader instance that works just fine, but if I use a Bitmap instead, nada...I could load the Bitmap into a Sprite and add the EventListener to that, but would prefer the direct method...
Sometimes I have a problem publishing to an xfl file. The bitmaps in the library do not save with the xfl save to the LIBRARY folder. I've tried resaving as another .fla before re-exporting as an xfl. but I do not seem to find the proper way to overcome this?
i have a flash clip that i am trying to imbed into a joomla website of mine, and the problem is that it doesn't auto-start. If i open the swf file it will show a blank screen until i right click play or ctr+entr, on the website it simply doesnt show the flash. here is the link to the swf file [URL]
I'm confused by a tip in Adobe's own documentation that says:Avoid using gradients, because they require many colors and calculations to be processed, which is more difficult for a computer processor to render.I understand how this would be true in a vector shape fill, but they aren't specifying vector. It seems to be implied they include bitmaps too, since the next couple tips are bitmap related.If they do in fact include bitmaps in this tip, can someone explain to me how this is possibly true? In a bitmap a pixel is a pixel. I don't see how it matter that the pixels form a gradiated color or not, the software still has to read and write each pixel regardless.
I'm looking for a good method to resize bitmap images to fit within the constraints of a container object whose size will change based on the browser window dimensions, etc. Basically, it needs to scale to fit. I'm using the following for resizing by height. "largeImage is a bitmap object.
I would like to have a SWC file with many bitmaps stored in it, which can the be called and loaded dynamically when they are needed.The SWC has been made, with the Bitmaps set to export.In my main class I am running into trouble trying to access these classes.Different sources are offering different advice, could someone advise the best way to gain access to these classes within the SWC, and the best way to access the SWC from within my file.URL]they offer a solution which involves having to statically name the classes at runtime (these arent exported bitmapdata classes but same idea)this second link is a person describing a solution to the problem described in the first link. His solution involves what appear to be either flex or command line compiler directives
I'm working on a flash website that consists of 3 frames (1 = preloader, 2 = instances of symbols, 3 = the main page/view). I've gone through and optimized all my static bitmaps/movieClips and removed any symbol that I've exported for ActionScript from exporting in the first frame. Even after all these steps frame one is still the longest to load (797kb on a 32.6 kbps simulated download), only showing the preloader when the whole file is at 86% complete. Any further steps to take to get frame one's size down?
I has a series of bitmaps which have been broken apart in flash, I want to know if it is possible to go into these bitmaps using their bitmapdata and edit them based on information on the arrays that I get. I.E. I want to delete the transparent pixels each one has.
Obviously I can do this by hand in photoshop or just using the lasso tool, but I have several thousand bitmaps that I have to edit, so I'm hoping theres a way to do this through code.
i've used a Loader and URLRequest to download a .png from the internet and add it to my display list. since it's already a bitmap, does it have built in bitmap data already? or do i have to create the bitmap data myself?also, why does the same trace statement return false in the mouseMoveHandler when it outputs true in the displayImage function?
var imageLoader:Loader = new Loader(); imageLoader.load(new URLRequest("http://somewebsite.com/image.png")); imageLoader.contentLoaderInfo.addEventListener
I would know if with AS2 it's possible to load programmatically a bulk of images and save them in an array; then how to attach programmatically each image to an empty movieclip.
I know how to do this in AS3 however it seems impossible in AS2.
I'm trying to position an image on top of another image based upon the make-up of the smaller image. The smaller image is a cut-out of a larger image and I need it to be positioned exactly on the larger image to make it look like a single image, but allow for separate filters and alphas to be applied. As the images are not simple rectangles or circles, but complex satellite images, I cannot simply redraw them in code. I have quite a few images and therefore do not feel like manually finding the position of each image every and hard setting them manually in actionscript. Is there any way for me to sample a small 5-10 sq. pixel area against the larger image and set the x and y values of the smaller image if a perfect match is found? All the images are in an array and iterating through them has already been set, I just need a way to sample and match pixels. My first guess was to loop the images pixel by pixel right and down, covering the whole bitmap and moving to the next child in the array once a match was found, leaving the matched child where it was when the perfect match was found.
Alright I'm programming in actionscript 3, using flex as a compiler. I have an 16x16 large PNG file that is basically a square outline like this:But in more noticeable colors.
I want to draw an 11x11 grid of these squares, so I use these for loops: for (i1 = 0; i1 < 11; i1 ++) {
I'm working on a project which draws circles continuously at framerate and animates them around the stage and I'm running into performance issues.
I'm already converting all objects to bitmapData as soon as they become static. My question is, will converting the circles to bitmapData as soon as they are drawn increase performance? In other words, is animating say, 200 bitmaps (with transparency) faster than 200 vector circles?
Are there any drawbacks to this technique? (I'm thinking opacity problems maybe?)
If they were more complex shapes than circles would the answer be different?
