ActionScript 3.0 :: Accessing Instances On Second Frame?
Jun 13, 2009
I can't seem to access instances in a movie clip that aren't on the first frame of a parent movie clip even if I tell flash to go to that frame before I attempt to reference the instance in the actionscript.
Actually this works in flash player 10 but not 9. I could just export for flash player 10 but I would rather know the answer than just avoid it and of course for better compatibility reasons.
I've attached an fla example with source code to show the problem. I'm using CS4 and programming in classes in as3 as you will be able to see from the example.
P.S: the example is saved in CS3 so more people can open it.
Edit: Since there's not alot of code I'll paste it here for people to see.
I am using CS3 / AS2 and was wondering if it was possible to load a movie into a symbol, not just an instance of that symbol, from the main timeline. I tried exporting the symbol for actionscript then using loadMovie but I suspect that is not the correct way to go about this.
PHP Code: symbol.loadMovie("urlToMovie");
Is it even possible to do this or do I have to change every instance of the symbol individually?
I'm setting up some Radio Buttons. The desired effect is when you click a button, it calls a function which loops through an array of the button states, switching them off.
The stumbling block is changing the state of the buttons from on to off. I'm sure it's an issue with the way I'm trying to get the instant name (eg radioBtn1) into the MovieClip Variable 'currentRadioName'.
The error I receive is: TypeError: Error #1034: Type Coercion failed: cannot convert "radioBtn1" to flash.display.MovieClip.
So I'm trying to stick some object into a MovieClip object, which obviously doesn't work.
With the GUI (Flash CS3), I made a button that included an instanced dynamic textfield. Whenever I try to access it, I get the error message 1119: Access of possibly undefined property
The line is: big_btn.labelTxt.text = "Start"; the button is named big_btn and the textfield is name labelTxt
If I change big_btn to a MovieClip, no error and it works.
Can you imbed an instance inside a SimpleButton? If so, how? If not, what's the logic behind allowing it in a MovieClip, but not in a SimpleButton?
I have programmed a game using the Flash authoring tool and a document class. I'm trying to graphically add instances and add functionality in the document class. Suppose I have a main timeline with 3 frames, each frame reperesents a different level of the game. In frame 1 I have an instance of the MovieClip class named tree1 on the stage and in frame 3 I have an instance of the MovieClip class named tree3 on the stage. In my document class, after an initial stop() command, I want some logic like: tree3.scaleX = tree1.scaleX; But tree3 is unknown to the runtime since we are not of frame 3 yet. Any way to access all the instances on all frames declared in the authoring tool from the document class?
I have mutliple instances on the stage of a custom ThumbNail class. As you click on a particular instance an associated enlarged external image will load. As this is happening I want to make sure that the ThumbNail class animations are inactive for all instances.
I was thinking of using a Boolean variable that would get set right before the image is loading. Using event.currentTarget should help with the instance that was clicked but how do I gain access to the instances that were not clicked?
I've been having a problem that I have not found a good solution for. I think this is a problem related to the Flash Player's architecture so an experienced eye here would be welcome.
Imagine you've got 3 symbols in the Library and create instances of them by dragging them onto the stage. Each object is linked to a class. Let's say the object classes are named ObjectA, ObjectB, ObjectC. Their stage instance names are objectA, objectB and objectC.
The classes of these objects reference stage instances. For example, ObjectA might have a reference to ObjectC, like this:
var _objectC = MovieClip(root).objectC;
ObjectC might have a reference to ObjectA, like this:
var _objectA = MovieClip(root).objectA;
It sounds like this should work but it doesn't. When the SWF is published, objects on the stage are instantiated in the order that they were dragged from the Library. This means if objectA is instantiated before objectC, it's reference to objectC will return null and the code will fail.
I know there are ways around this, but I'm trying to come up with a solution that doesn't involve the document class, a helper class like a singleton, or instatiating objects with addChild().
It seems that the only way you can be absolutely certain that all the objects have been instantiated is on the first frame of the movie. So I've been using a system that adds an enterFrame event listener to just get references of stage objects when the first frame runs, like this:
function findStageInstances(event:Event):void { var _objectA = MovieClip(root).objectA; var _objectB = MovieClip(root).objectB;
[code]....
(Note: The ADDED_TO_STAGE event won't help in this case because objects are added to the stage by the SWF based on the order they were dragged onto the stage from the Library.)
I have a movie clip on the root which contains my menu. And another movie clip which plays my video. Basically when i click a menu item it calls a function which i want to able to send a command to my video player to play another video.
This is code inside my video player movie clip (i've missed out the including of the class and various config stuff - below is just so you see the name of the class instance)
var MDVideo:MD_VideoPlayer; var videoPath:String = "assets/ski_video.flv"; MDVideo = new MD_VideoPlayer(videoPath, local_config_obj);
[Code]....
How do i access the MDVideo instance from my menu movie clip?
i know its probably been answered here before but I havent been able to find exactly what i need to make it work. Plus this is my first time doing AS3 so
my movie is linked to an external class called game, and in the game cosntructor I am trying to access instances on my stage. I have tried MovieClip(root).instancename, root.instancename and even tried adding an event listener to listen when the movie is done loading because I thought maybe it was because the instances on the stage weren't created before the constructor is ran. This is the main class, shouldn't it be easy?
i've been all afternoon trying to figure out a solution to my problem, and I can't seem to find it, or cannot implement it. Let me lay it out for you: I have an actionscript file linked to a movieclip. (movieclip:skate class linked: generic_skate).I have it set up that way so I can create an array of skates easily (i'm using a for loop to create them), and each skate has its own attributes (name, description, price and the image that is supposed to go on the deck)In the stage, i have three text boxes, one for the price, other for the name, and another one for the description.In the generic_skate class, I'm handling all the mouse events (in this case mouseOver and mouseOut.
What i want to accomplish is: when the user hovers over a skate, the info shows up in the text fields and when he hovers out, the info goes away. My problem: Since I'm doing all the mouse interaction in the class file, my guess is that I have to access the stage to get to the text boxes that are placed there to change its info or somehow create a "middle" man to do all the handling.
is there a way to scope instances that haven't been instanced in the first frame of the movie?I got brave and nested my btn_mc clips inside a nav_mc.On an action layer in the first frame of my timeline I have:
_root.nav_mc.btn1_mc.gotoAndPlay("start");
for example.In the nav_mc timeline this works if and ONLY if the btn1_mc instance is on the first frame of the nav_mc timeline.I'm trying to update my skillz and put everything in the first frame of the root timeline rather than doing the backasswards syntax on the mc itself this (onPress) which really confused me for about five years.
I want to make the timeline go to the next frame (ie gotoAndStop) only if two button instances are invisible. For the buttons I have scripted an on(release) to make them invisible, but I don't know how to use the if function to make my animation progress when they are both invisible.
Ok, so I made a custom class, but I did not want to add all the text to it through code (much easier to type it in flash on the frame). I name the instance aScoreBoard.
As my code runs, I need to call some of the functions that are part of the ScoreBoard class. As the code gets to this point, I try this line:
aScoreBoard.UpdateScores(passArray);
which will update the scores on the scoreboard. When that line in AS3 tries to execute, I get this error:
TypeError: Error #1009: Cannot access a property or method of a null object reference. at Main/Main:ayEnd()[C:projectsDev_LearningLongJumpsrcMain.as:616] at Main/Main::ButtonAfterJump()[C:projectsDev_LearningLongJumpsrcMain.as:606]
Is there a way to do things this way? or will I have to go and do all the extra text entering in the code?
I have a movieclip placed on the stage called splashScreen. Inside this movieclip i have a button called easy_btn on the second frame but every time i try and access this button from the main timeline using actionscript i get the message TypeError: Error #1009: Cannot access a property or method of a null object reference.
I'm not sure why because i think i have referenced it properly. Here's my code -
splashScreen.easy_btn.addEventListener(MouseEvent.CLICK, chooseEasy); function chooseEasy(evt:MouseEvent):void{
I have a character that I want to animate. Now each part of his body is a separate movieclip. What I want is that, for example, if you imagine the shoe MovieClip, I want to give it three frames - from the front, from the side, and bent.
So when I animate the character MovieClip, I would like it if I could keyframe the currentframe of the shoe MoveiClip, if that makes any sense. It's easy enough to do in ActionScript, but the problem with that is the change isn't visible until I test the movie, and when animating it's useful to see exactly what the character looks like at each frame. Is there any way of setting the current frame of child MovieClips when animating?
I am a beginner in Flash development and I was just recently assigned to fix an old Flash project at my work. Essentially, the application is a video booth whereby users can record up to 60s of video via their webcam and then share it either via email, twitter, or facebook. When the application is started, a video ID is generated, and that is used as the video's file name when it is streamed and saved to the server. I am sure there is a better way to do this, but the way I came up with is to grab that video ID and pass it to the "Share" page as a URL variable, and then use that to access and share the video from the server. How I can access the video ID from the button that is sending the user to the "Share" page.
Here is the code: var nc:NetConnection = new NetConnection(); var ns:NetStream; var cam:Camera; var mic:Microphone; var vidId:String = configName(); function tracer(p_s) { [Code] .....
i have a mc in wich timeline i put (manually) a mc called joe_mc. The first one (the container) holds all the code: A timer function slows down joe_mc and when it reaches its last frame its suppossed to play the next frame on the container mc timeline. Here�s the code:
I have a 20 frame movieclip (named mc), and by default the playhead is stopped at frame 0 of that movieclip. At frame 10 I have a movieclip instance there named "apple". Now I want to tell mc to go to frame 10, and immediately access "apple" movieclip. This is what I do (from the main timeline):
mc.gotoAndStop(10); trace(mc.apple);
It prints out null (appled is undefined). However, when I put a timer (say of 5 milliseconds) before calling the trace statement, then it works and can access apple. I don't want to rely on timers, since the timer duration depends on different circumstances. At the same time, I do not want to put code anywhere except the first frame of the main timeline.
I have the Dynamic Text field that has an instance name on a mid-timeline frame in Flash CS4. I have a class that inherits from Sprite, and which is always added to the stage on instantiation. How can I get a reference to my Dynamic Text instance from this class?
Example: My Main class (linked in Flash's publish settings) goes like this: protected function beginGame(e:MouseEvent){ gotoAndStop(8); var game:GameContainer = new GameContainer(41,8); addChild(game); game.x=36; game.y=128; }
Game Container extends MovieClip, and draws some pretty gfx. On Frame 8, in the Flash IDE, there is a Dynamic Text element instance named "scoreText". I want to access this from the GameContainer class. Possible?
I have been searching for a resolution to this for weeks but to no avail. I have made a game already where I had a character names mainChar placed on the screen using the Flash IDE. With this method, i was able to access it's various nested movieclips such as mainChar.walk and mainChar.jump. The problem is that I am making a new game where the main character is loaded via external code using hero:mainChar = new mainChar(); in the external file. after this, i would like to check what the current frame of a nested movieclip is. for example, hero.walk.currentFrame. however, by initializing it using the external code, as opposed to my previous method of placing it right on the stage, the compiler is not picking up of hero.walk.currentFrame stating that "a term is undefined and has no properties (error type 1010)". Is there any way for me to let the compiler know that the nested movieclip is there. It's odd because i can state hero.gotoAndStop("walk"), but when i say hero.walk it gives an error, so i know it isnt spelling.
Background: I have a project where i need to create multiple objects that consume the same base calss from an external .as file. each of the individual fla files that consume the base class need to pass a variable to the base class so the class can return information specific to the fla.
My question is,if i have an external class path set up, how do i get a variable on the first frame of the movie to be visible to the base class && how do i call upon its value from within the class.
i've tried placing the code in the actions pnel of the mc; on the mc at the main time line and in various other unspeakable places... but i always get the same error warning me that this code can only be used in movieclip instances and that my stupidity levels are reaching dangerous levels. (error: 'Symbol=stage_mc, Layer=actions, Frame=1: Line 5: Clip events are permitted only for movie clip instances
onClipEvent(enterFrame){'
i fear somebody will reply to this with:'the code goes on the movieclip instance'...at which point i will take up a career in knitting (i knew i shouldn't have given up the course in the first place)
What command do I enter for the movie to rewind to first frame on entering a certain frame / stopping in a frame?It's my first time using Flash, and I'm working on a double menu (second menu has a "close" button, where I want to get back to the first menu).
i have a movieclip on stage. it has 3 frames but is stopped with "stop():" so it only shows the first frame on mousedown i want it to play frame 2 for a duration of 1 frame then frame 3.
This is a snippet of some code I'm working on. Currently I have a mc that you press that plays another mc. That mc that reacts has 5 frames, each frame with stop(); on each frame. I do a normal play code because it lets me play through and cycle back to frame 1 after frame 5 (so if I click the mc it eventually cycles back to the first frame and starts the process over again). If I do a nextframe it stops at frame 5, so that's why I use play.
press_mc click on it and it tells mover2_mc to advance a frame and recycles back to frame one to redo the process.Can I tell press_mc to play and skip a frame or to have it play a list of frames that I tell? I can't do a _currentframe +2 because it'll halt at frame 5.
Not sure where the difference lies here, but I am trying to understand it. In this piece of code that is a public function of a MC with instances of other MCs in it, I cannot seem to access the instances except in a function within the public function (confused? so am I but here's the code)[code]...
