How to control the main timeline of buttons in a movieclip - jobs in peril!

I'm doing something simple in theory. In my main script, I have a series of images with labels for each image. In a movieclip (with its own labels and script) under the images, I have two panels of butttons flop back and forth (to save space). The idea is to have the script simply main plays the frame specified by the corresponding button in the movieclip. I tried the parent.child thing, but im hurt, or is not the solution. If anyone can help me I will be saved from certain death. If you think that any other part of my project can be blamed, ill be happy to provide you with anything that can help. Thanks in advance.

Here is my script:

ActionScript code:
function on1click(evt:MouseEvent):void {     gotoAndPlay("pic1"); } thumbPanel.pic1_btn.addEventListener(MouseEvent.CLICK, on1click);

This is the error:

TypeError: Error #1009: cannot access a property or method of a null object reference.
at gallery_fla::MainTimeline/frame1()

1009 error indicates that one of the objects targeted by your code are out of reach.  This may mean that the object...

n ' is not in the display list
n ' is not have an instance name (or the name of the instance is misspelled)
n ' is not in the frame where this code tries to talk to her
-is animated in place, but is not assigned the name of the instances of each keyframe for her
-is one of the two or more consecutive keyframes of the same objects without a name assigned in the image previous (s).
 
If you go to your section to publish the Flash settings and select permit debugging option, your error message should have a suite of line number the number of the frame that will help you to isolate the object that is involved.

  • Toolbox for CreateJS: how to control the main timeline from outside the canvas.

    Hey everybody,

    I'm currently doing something simple, but my animation film breaks whenever I try to change my code. I created a basic animation in Flash where an object moves from the left side of the canvas, to the right and then loops of the last frame of the first image. Nothing else. The animation is simply placed on the main timeline. I exported the animation with the Toolbox for CreateJS through the extension of the Flash and animation series as it should. I'm trying to start and stop (reboot of the first image) the animation with the mouse on and off mouse events. I want that the events to fire when wriggling over/stop a div outside the animation canvas tag. Is this possible with CreateJS? I'm trying to find a way to control the main timeline without being inside the canvas tag.

    HTML example:

    http://www.thephotoncore.com/testing/example_test.html

    Example Code:

    < id article 'container' = >

    < canvas id = "canvas" width = "550" height = "400" style = "background-color: #cccccc" > < / canvas >

    < section id = "animation_control" >

    < p > hover over to start and stop animation. < /p >

    Hi DjPhantasy5,

    All the clips on the scene are children of the scene,

    So now the "mouseover" all clips on the stage could be stopped with stop and on the "mouseout/mouseouthandler()" all the children could be restarted with gotoAndPlay like this:

    function Stop()

    {

    If (stage & stage.children)

    {

    var t = stage.children.length;

    for (i = 0; i< l;="">

    {

    child var = stage.children [i];

    If ('stop' in child)

    Child.Stop ();

    }

    }

    }

    function Restart()

    {

    If (stage & stage.children)

    {

    var t = stage.children.length;

    for (i = 0; i< l;="">

    {

    child var = stage.children [i];

    If ("gotoAndPlay" children)

    child.gotoAndPlay (0);

    }

    }

    }

    See http://www.liauw.nl/forums/adobe/djfantasy5/index.html

    But it is also possible to expose "ball1", for example, by adding it to the document.

    This can be done by adding the code for "ball1" as follows:

    / * js

    document.ball1 = this;

    */

    Then stop the animation would look like:

    function Stop()

    {

    If ('ball1' in the document)

    document.ball1.stop ();

    }

    etc.

    Have fun!

  • Control the main timeline and chronology of built-in movie clip

    Good afternoon folks,

    I am trying to solve this problem.  I have a main scenario with an animation. (animation is not a clip).  I also have a clip film embedded in the main timeline. I want to control the actions of the main timeline AND the embedded animation at the same time.

    For example, when a user clicks on a button "pause", I want to stop the animation of the main timeline as well as the integrated clip. I figured out how to stop the main timeline using the stop(); command.  I also understood how to stop the film incorporated using the command _root.embeddedclipinstancename.stop ();  Problem is that I don't know the commands to stop the two things at the same time.

    I tried to find that an instance name for the main timeline, but there is no (I think). I know I could do the animation in the timeline in a clip, but I don't want to go that route.  Any ideas on how to control two things?
    Also, if possible, I would prefer not to use the _root command since I know that this can cause a conflict in Captivate.

    Thank you.

    Include the two commands that worked in your pause button code.  If your [ause button is on the main timeline, you don't need to use a reference of _root.  It is only really useful if you target some of child level object distance back to the main timeline.  You can _parent (and string them if necessary) instead of using _root.  As you will get in trouble unless you're on the _root timeline when using it.

  • Button inside a clip controlling the main timeline

    Hello-

    I have a clip on the main stage - inside that movie clip is a button - I want that button to contol a function on the main timeline.

    example: the Script button

    closeAll_btn.addEventListener (MouseEvent.MOUSE_DOWN, goCloseAll);

    function goCloseAll(e:MouseEvent):void {}


    * do not know what to put here to activate "closeAllOpenMovieClips" on the main stage *


    }

    example: main stadium Timeline Script

    function closeAllOpenMovieClips (): void {}

    lost_arts_mc.gotoAndStop (1);
    rain_mc.gotoAndStop (1);

    }


    do not know if I need a script more on chronology of main stadium that comes "from function."

    Thank you - Ben L

    If the button is in part 2, then the event listener so that it must be well on frame 2... or you could make the button visible/invisible betrween frames 1 and 2).

    But if you want to head back to your original approach...

    closeAll_btn.addEventListener (MouseEvent.MOUSE_DOWN, goCloseAll);

    function goCloseAll(e:MouseEvent):void {}

    MovieClip (root) .closeAllOpenMovieClips ();

    }

  • Control the main timeline of a movie via a button in a movie on another level.

    Hello!
    I have two film is at two different levels.
    Level 5 is my base film and I load another movie on top of that in level 10.
    Once the user clicks on a button in the movie to level 10, I would like to animation to level 5 to stop (the animation runs on the chronology of the main root of level 5).

    Once the user clicks a different button in the movie to level 10, I would like the animation in the main timeline of the movie in level 5 again from the moment it was already stopped.
    Is this possible?

    It would be great if someone could help me with this.
    Thank you, midi_ie

    You can't delete this loop of onClipEvent (enterFrame) unless you remove the movieclip to which it is attached. However, you can add an else if statement in your code (in addition to checking the variable Boolean "drag") to check if your _level10 button has been activated.

    and you can delete a slider.onEnterFrame loop, but you probably don't want to do.

    p.s. make the loop enterFrame?

  • How to get the main timeline SWF frame rate?

  • Control the main storyline of the film loaded

    I loaded an external film on the main movie in a movie clip called "mainholder" - in the main storyline on the main sequence there is a command to 'stop' on frame 1. The film loaded, I want to control the main timeline and tell him to go to frame 2. Can someone tell me the actionscripting to do this, I have tried several commands and frustrated. ;-)

    Thank you

    OK... _ is necessary to _parent and _root... all other instance names are called by their name on the timeline then... in the case of this file, try this

    {We (Release)}
    unloadMovie (this._parent.loadsgPhotosMain);
    }

  • in actionscript 3.0 how do a nested movie clip button go to a section on the main timeline

    I do a site based in flash actionscript 3.0, I have a button nested in its own clip, because I have the button bigger to be able to read what I realized the only way to do it is by creating it as a film clipa nd inside the clip in a button

    I've added an event listener for the button of blog, saying:

    blog.addEventListener (MouseEvent.ROLL_OVER, gotoblog);

    function gotoblog(evtobj:MouseEvent) {}

    gotoAndStop (2)

    }

    This part of the code it goes to 2nd part of the scenario that it is and stop wich is a version of the origanal symbol breath

    I added a second order on structure 2

    blog.addEventListener (MouseEvent.CLICK.gotoblogpage);

    function gotoblogpage(evtobj:MouseEvent) {}

    gotoAndStop ("blogframe")

    trace ("the blog button has been clicked")

    }

    I have named the blog of symbol and use the name from where will the blog page to be "blogframe" this line of code at the bottom is where I run trouble the window output in Flash says "blog button has been clicked" I like it. no errors are accouring why that which is at the playhead does not attend the image "blogframe"? If the button does not work when I click on it the code is correct, I think the problem here is he does not want the read head go to the section I want it. So I gues, my question is, how can we make a button less, a clip interact with the main timeline?

    One way to do this is to target the root timeline...

    MovieClip (root) .gotoAndStop ("blogframe");

  • Button on the main timeline control movieclip

    Hello

    I have a stop in my main script. At the stop, I have a play of movieclip. In the movieclip, I'll have a video playback. After playing the video, I have a button for the user to continue playing until the end of the movieclip. Once the movieclip is done, I want back the return to a specific image in my main script.

    I can't figure out how to make this work. Anyone have any ideas?

    Thanks in advance,

    Paul

    How much of what you just described in currently working properly?

    If it's just the last step to have the game finished main scenario the movieclip, then you might have an event listener assigned to this movieclip in the main timeline.  When the movieclip ends it can send an event of this listener that can trigger an event handler function in the main timeline to tell the main scenario for continued as planned.

    Another less glamorous but more compact approach might be to have a drive inside / at the end of the movieclip to order the main scenario of an act using something like...

    MovieClip (parent) .gotoAndPlay (whatever);

  • How to target button in movieclip on the main timeline

    Hello!

    I have a few buttons of submenu in a movieclip in the mainline. My first level of navigation in the main timeline. The submenus are grouped into movieclips on the main timeline. I basically used the same code on the main navigation for the navigation sub except the code for the submenus is located in this movie clip. My instruction trace bed button is clicked (which was a quantum leap for me) but I know that I need some kind of code _parent in there so that he knows to go to the label back on the main timeline. Can anyone help? I feel like I'm so close.

    Also is this a correct way to set-up? I couldn't figure out how do it in an image. Any help would be so appreciated. I didn't know that this basic framework would be so difficult.

    Here is the link:

    One of the reasons that I never won any price for my vision of the design are because I am often... If it works, use it.  There are many ways to approach a design and yours is very good if you understand.  If she was going to smash something, it would have happened now.  Some people don't go to the extreme of having absolutely no code in a file, some even no content library, he wrote everything in files and class not by necessity, but to simply believe that it is the best way, or a challenge to prove their skills...  They have the it.  He participates a practicality with design that allows to make Judgment calls and if you feel that your approach to design is convenient for what you understand or which meets the needs of the project, then you have the right to follow your own path.

    That said... in the case where a person must inherit from your work somewhere down the road, that's when your approach can be victim of judgment... If someone can not follow, either found it difficult to put all the pieces together, or find them, then you become the contact person for the moans fall that follows.  But you're not likely to have to hear about it.  Yet, one day, if you are in a position where you inherit a person guestroom... and start whining about how they did it, you will come to appreciate the reasons to consider how approach you your designs.

  • Close button in an interpolation that takes back you to the main timeline

    I have a HTML5 canvas document that has 5 separate click to open the motion tweens.  Within each tween, I have a "close" button that I want to return at the beginning of the main timeline.  Right now he's just at the beginning of the timeline to tween movement in an infinite loop.  How can I get to go back to the main scenario for each of the interpolations of?  (For reference, I am a beginner with Animate and JS code and have not been able to find this answer in my many searches on the web).

    you want that code in the main timeline to lead the scenario primary back to its first image and stop, or you want to code on the timeline of a movieclip lead the main timeline at its first image and stop or something else?

    If you want the code on the timeline of a movieclip to lead the main timeline, use:

    this.parent.gotoAndStop (0);  assuming that the parent of the movieclip is the main timeline.

  • Control loaded swf on the main timeline

    Hello

    I'm working on loading external swf files for ios. I am able to load swf files and assembled visible or invisible in different settings. I have trouble controlling the swf files loaded on the main timeline. Specifically, I would like to have a button on the main timeline, that when you click on will move a swf loaded to frame 1.

    Here is a code that loads a swf file:

    var myLoader1:Loader;

    var loaderContext1:LoaderContext = new LoaderContext (false null, ApplicationDomain.currentDomain),

    if(myLoader1 == null)

    {

    myLoader1 = new Loader();

    addChild (myLoader1);

    }

    myLoader1.load (new URLRequest("folder/file1.swf"), loaderContext1);

    myLoader1.visible = true;

    backbutton.addEventListener (MouseEvent.MOUSE_DOWN, backbutton1);

    function backbutton1(myEvent:MouseEvent):void {? myLoader1.gotoAndStop (1) ;}}  (this line does not work)

    (Once I load file1.swf, in the file1.swf I click a next button to move on to different periods.) My question is: hHow do I code the "backbutton" on the main timeline so that it causes the file1.swf to go to frame 1?)

    Thank you for your help.

    After loading is complete (and assuming that you load an as3 swf), you can use:

    MovieClip (myLoader1.content) .gotoAndStop (1);

    assign the movieclip an instance name (in the properties panel - for example, mc) and use:

    Next.addEventListener (MouseEvent.CLICK, f);

    function f(e:MouseEvent):void {}

    mc.nextFrame ();
