ActionScript 3.0 :: Switching Between Frames In Flash
Mar 21, 2012
I've been having a problem with an interactive Flash CS5 project: when I navigate between frames using gotoAndStop(1); the program experiences the following error: Error #1009: Cannot access a property or method of a null object reference. I think this is because the first frame that the function goes to has none of the objects that have event listeners in frame 2. All I'm hoping to do is go back to the first frame. Would it be best to put everything on one frame and work from there? That seems unneccessarily complicated.
I read a tutorial a while back about making a symbol for a character's mouth in an animation, and making multiple frames within the symbol, with one for each different mouth position I'd like to use (Open and saying a certain letter, smiling, frowning, etc.). What I can't figure out is how to keep it from constantly animating repeatedly through all the mouth frames on its own in each shot when I just want it to stay in a certain position on certain sequences of frames. I also can't figure out how to select the precise frame I want when it needs to change.
i am trying to make it so the weapons will switch when i press the a,b,c,d,e button on the keyboard( i will figure out the actual button l8r) i have made a mc clip button to make it switch which works but i cant figure out how to do it from the key board
i have an rtmp folder with videos,I am trying to do a seamless change to next video using nestsream play2 method.have tried using the fast switching of NetStreamPlayTransitions. SWITCH like below.[code]The problem is the switching is not happening.offset=-1 is supposed to be fast switching. The idea is to make a seamless transition to the next video.if we dont use any transition method or use opts.transition = NetStreamPlayTransitions.RESET;its the same as not using any. It just switches normally.RTMP is supposed to provide a relatively faster transition, i am looking for a seamless option .
Let me preface this post by saying I have been studying actionscript 3 for 2 months now and I am now at a point where I am looking into how experienced developers code their projects and what tools they are using. Repeatedly, I come across a post or a blog entry where a developer says:
[Code]...
Now here comes my confusion/question(s). When a developer says something like that, are they saying that they ONLY use FDT to create their projects? If so then how are they going about doing it without the use of the Flash IDE? Do they just keep creating external .as classes and then link them all together or what?
In my 2 months of studying, I really feel like I have learned a lot, but I cannot seem to wrap my head around this. I want to break away from the Flash IDE (if at all possible) so that I can go deeper to the code.
I've coded a little game, but now I realized that I should include all the actions to frame on layer called "actions". This far I've written my code to movieclip.transforming this to frame?
I've done a lot of Flash development and have been meaning to try out canvas for a while, but after browsing through some tutorials, I can't understand how this is supposed to replace Flash.
Note: I ask a lot of questions down here. I don't really expect them all to be answered. What I'm really looking for is some basic guidance about how I should be thinking while developing on <canvas>.
From the spec, it looks like <canvas> is really more analogous to the Graphics class in Flash, which one would use something like this:
class ColoredCircle extends Sprite { private var _color:uint=0x0; public function ColoredCircle(color:uint) {
[Code].....
Should I be treating <canvas> like a Sprite? Marking everything as position:relative should allow me to basically duplicate display list-type behavior (I don't believe that you can nest <canvas> elements, but you could probably do so by throwing in a bunch of <div>s). However, I use a lot of Sprites in my projects. That's going to be a metric crap-ton of tiny canvas elements. Also, how do you handle mouse events in <canvas>? Do they trigger if someone clicks on a transparent part of the canvas's box model (bad)? If I have a canvas with two circles in it and I need to know which one gets clicked on, do I have to do bounds-math with the mouse position?
I've coded a little game, but now I realized that I should include all the actions to frame on layer called "actions". This far I've written my code to movieclip.
i know how to program in vb.net, and have little problems switching to action script. the only problem im having is that i dont know where to type my code. in visual basic there were events that you would type into. does any one who knows Vb know what im talking about? i get the whole convert to symbol stuff just not where im supposed to type
For the downrankers:I have searched this question in the internet and found countless posts. But neither worked because of a small problem here or there, and when I though of posting my problems in the same thread I realized its a month/year/millennium old. So I'm gonna ask here.For other people:How do I switch scenes within a flash MovieClip object?
From Frame 1 to 15 I have a button movieclip which will when clicked on switch to frame 16, but a different button exist on frame 16. This button on frame 16 should have the same functionality as the one at the beginning when its clicked on but switch to frame 24. For some reason I'm getting a:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
Here's my code for the button at the beginning which works:
startbutton.addEventListener(MouseEvent.CLICK, fl_MouseClickHandler); function fl_MouseClickHandler(event:MouseEvent):void { gotoAndStop(16);
I've built a multilingual ASP.NET web app and no problem . I'm trying to put a flash header for this website so I've made couple flash in different language ( because they are different not just in language , they have tiny different because of different cultures ).how to load specific flash while switching different language .
I have a simple HTML page that contains two tabs that show/hide content in the same space.The first tab contains an SWF file that is embedded using SWFObject.js.When switching between tabs, I would like the SWF file to pause or stop. This works fine on all browsers except IE7+, which is a known problem.What could be possible resolutions?A simple solution would be to remove the SWF file from the DOM and re-insert it every time the first tab is selected and loadedThe SWF file is generated using Adobe Captivate 5. Do I need to expose a pause/stop method using ExternalInterface API that Javascript/jQuery can call? Or, is there a standard method for pause/stop that is exposed for all SWF files that I can simply call?
did anyone else notice after switching to flash cs5 the auto format will fail constantly? 90% of the time i comment something out the auto format will error.
I have a swf that loads images from my server and resizes them to fit the 800x600 stage size. The original images are stored at 1024x768 max pixels. The user can press a button to go into fullscreen mode. What should I do to show the images at the best quality?
a) should I resize the loaded images to their max size (1024x768).
b) do I need to reload the entire image if it has been resized to 800x600 or is the original image still accessible and I can replace the 800x600 image with the original?
I am using AS2 and Flash 8 (but require users to have Flash Player 10 for fullscreen)
Is there an easy way to switch out a movieClip for another dynamically loaded movieClip?
I have and eventListener onCLICK that when selected it starts an FLVPlayback but I would also like to swap out with another movieClip Play Now / Now Playing button.
Just some background. I am looping and loading a play button jpg's into one movie clip and assigning an incremental number as a name to the play button movie clip. On Click that play button plays a movie but now I would also like to switch the play button graphic to a playing now graphic.
//ADD EVENT LISTENER TO ALL MY THUMBS_BUTTON thumbs_button.addEventListener (MouseEvent.CLICK, playVideoThumb); for (var i:Number = 0; i < my_total; i++) {
I have a client where some of their employees have flash installed and some don't. So always using the swfuploader module widget isn't going to work and it doesn't gracefully fall back to HTML. In fact it just leaves a non-functioning button in its wake.
So what I would like to do is detect when they don't have Flash available and switch to the standard Drupal File Upload widget. Now in my head it seems like this would only work if done on the server-side. But can that even be done reliably on the server side?
Also, can this on-the-fly widget switching even work in Drupal or will it pitch a fit?
why the getDefinitionByName function works with "com.foo.Bar" and gives error with "com.foo.Rab"?My only clue is that the class com.foo.Bar was created before importing the project to Flash Builder 4.5 for PHP (4.5.1 namely).
My question is very specific, in fact you could try for yourself if you had FB4.5.1, a prior version of the same program, and a lot of time. Obviously I'm hoping to find someone who have experienced this particular issue or any related issue with similar functions.
When setting up a Stage3D's Context3D for rendering, is it expensive / bad practice to switch between Program3D's in an Event.ENTER_FRAME cycle?I don't have an example at hand, but I'm curious to know if there's such situations where this alternation between programs would be used and if the frame-rate would suffer considerably.
Does anyone know if we could switch between flash player version and the debugger version? I think there was a way during flash player 7 times. All I could find on this is that people use different browsers, one for the player and one for the debugger.
I am passing to the source property of a VideoDisplay component a DynamicStreamingVideoSource object with 3 different dynamic live stream items, described by this XML, for your consideration:
But the player then runs the stream with the lowest bitrate, out of those 3. Wasn't it supposed to go for the stream with the highest bitrate, that is viewable by the end-user? All 3 streams have been individually tested and they are all viewable.
I've got a web site up and running that allows the user to choose a dark or light color scheme
But on the project detail pages, there are Flash videos that also change slightly based on which color scheme is selected.
[URL]
If you start playing the video, and change color schemes, the flash player will change to the right color, but on refreshing, it doesn't remember that change. How do I modify to code below so that the Flash player reads the correct color scheme and takes action?
Pertinant code is here (full JS file is here: http://www.centerline.net/lib/js/site-unmin.js): //Switches color of Flash Video player on detail pages function updateColor(color) {
I want to create a preloader that plays a certain amount of frames as it loads the rest of the frames. So, I have labels on the frames basically and need a preloader to play the "loading" frames as it is loading the "content" frames. Does that make sense? I have no idea how to even start this one... p.s. I am using AS 2.0, but if it can be done in 3.0 easier, I can switch over its no biggie
there seems to be no accepted method of playing multiple flv using buttons. My latest attempt has me putting multiple instances of the flvPlayback component in different frames and using buttons to navigate to those frames. It works but nothing anyone has posted anywhere will result in removing the flv when you go to a different frame and instance. This was simple in AS2. Load movie to a traget and each time you load a new movie the other one goes away. REALLY goes away.
basically im making a quiz on my main timeline ive got my questions and answers and on the last frame i want it to say how many answers the user got right. ive made a movie clip on this last frame. in the movie clip ive got 11 frames with the posible totals so frame one would be 0/10 frame 2 would be 1/10 etc what i want to do is when the user clicks the correct answer on the other frames i want flash to make the frames within the movie clip to go 1 step forward.
I have a function that counts days and some other variables and displays the values via dynamic text.
[Code]...
I have to place the incrementCount(): function every 12 frames so that it increments the values. Seems like it would be easier to simply modify the script to count "every 12 frames" but I can't find anything that tells me how to "count frames" in flash. Seems to be this is probably basic but I've searched unsuccessfully....so how do you do this. How do I get my script to work so it's frame based so I don't have to put incrementCount() every 12 frames?
Is it possible to have an movieclip of about 50 frames and navigate between these 50 frames? As if u put a marker on frame 10 and one at frame 30 and if u use a button it plays to frame 10 and stops and use another button to go from frame 10 to frame 30 and stop... and reverse if u use the earlier button.
I'm making a very simple adventure game with a dialogue box. The dialogue box is a dynamic text box. I need it to display the next message everytime the "next" button is pushed. Right now, this is how it looks.
I want to preload all of the voiceover swf files before a lesson starts so that they are instantly available when each frame / page that incorporates a voiceover is first visited.
