ActionScript 2.0 :: Calling Child Movie Methods From A Parent Movie [MX]
Jun 16, 2003
I'm working on a Flash MX application which involves a Parent movie and a Child movie.
I've loaded the Child movie into the Parent movie using LoadMovie. The instance name of the Child movie is Child1.
In the Child movie I have a user-defined function called getChildXML (we don't need to get into more details about the function).
The point here is that I want to call the getChildXML function from the Parent movie. I've tried something like Child1.getChildXML(); but with no luck.
I Have 3 Movies:MAIN.SWF, contains loading movie actions for Nav.swf and Home.swf.NAV.SWF, contains navagation menu loaded on Level 2 in Main HOME.SWF, contains slideshow for home page loaded on Level 1 in Main In NAV.SWF, there is a MOVIE CLIP "graphmc", which contains a BUTTON "graphicbtn", When this button is clicked, I'd like the HOME.SWF (which is loaded into Main.swf on Level 1) to fade out and unload, and load and fade in Graphics.SWF in place of it.
I have an external swf (sub.swf) that loads into my main swf. The external swf has buttons of its own...that I would like to use to load additional external swf's in its place. I click on the buttons and nothings happens.
My current code is as follows:
All of the following code is in my main.swf ================================ //Location where the external SWFs will load var Xpos:Number=18; var Ypos:Number=10;
[Code]...
External swf has no code except for a stop action.
I pieced this current code based on various articles I've found on the net.
I am loading external swf's into a main load.swf, using a Moviecliploader object. What I basically want to do is that, after an external movie, say home.swf, loads another external swf, say about.swf, home.swf should be unloaded.
home.swf is loading about.swf into the _root.mc_holder, which is placed inside load.swf. I want all external files to be placed within this holder. Now this is working with some files, but not with others. My standard code within all files is this:
//code within home.swf to load about.swf var loader:MovieClipLoader = new MovieClipLoader();var ldrlistener = new Object();loader.addListener(ldrlistener);ldrlistener.onLoadStart =
i am trying to use the Tween class to change the size of movie clip to certain height.the code works for me but when resizing the parent, it effects the child.i tried the height and scaleY property for the thum, but does not work.
Imagine the following setup. The main swf loads a child swf.In AS2 i would simply use _parent or _root to call the desired function. How can that be done in AS3?Can this still be done? Can I call a function on the main swf from the loaded one? How about the other way around, this time, from main to loaded swf?
I have a parent class that instantiates a MenuClass and handles transitions between pages.[code]And here's the MenuClass which creates forward and backward buttons. Clicking each will tell the above ParentClass to transitionForward() or transitionBackward() respectively.[code]One one hand, I feel like the MenuClass is too tightly bound to its parent and is thus less reusable. On the other hand I feel like, in the interest of keeping everything self contained, it's not the ParentClass's responsibility to reach into the MenuClass instance and add event listeners there. This seems like there should be some kind of OOP rule-of-thumb to govern this kind of relationship.Is my MenuClass too tightly bound to its parent? And if so, do you have any suggestions that would loosen that coupling?
1) i have all my actions in its own layer on the main timeline, so all is well there
2) i have a movie clip with a rollOver and rollOut events attached to it
3) inside the movie clip when the rollover happens and the movieclip stops at a certain frame, i have another movieclip that appears. the movie clip is a link to a website, it works properly on the main timeline but without the proper actionscript it of course will not work inside its parent movie clip
i'm a designer trying to step up my flash skills and have a scripting problem that's causing me trouble. essentially i have a child swf loaded into a container in a parent swf and want the child to be able to instruct the parent. to explain in full, the child contains an flv with bespoke video player components. it's container sits in one frame of the parent. when the flv finishes playing, i need the parent swf to move onto another frame. as it's a controllable flv, it isnt possible to predict the exact length of time the child will need to be present, so it literally needs to tell the parent it's finished playing at that very point.
I'm having a hard time working out the most appropriate way to move a child movieclip between parent objects.
I'm creating a board-game type game wherein I've dynamically created an array of 'Square' movieclips, with no visual elements, which are arranged in a 10x10 rectangle on the stage. I then dynamically add the appropriate types of piece movieclips to the various squares with the addChild() method. In general, a square should only have one child piece at a time.
All of this works well for setting up the play area, but now I'm having an issue with moving a piece from one square to another. I want to have the user click a square with a piece on it, then click the destination square to move the piece. I have the logic for determining where a user can move any given piece to, but I don't know how to actually move the piece.
The pieces are all different class objects that extend both a base class I call Piece as well as the MovieClip class. The main issue is that when dynamically adding the various pieces to the squares, I don't provide them a unique name to access them later. I don't bother with unique names because I have no way of knowing which piece instance will be in a given square, so using getChildByName(name:String) isn't very useful.
So I can think of two routes that I can take: Making a getter/setter for the Square class that manages a private Piece property (as well as the adding and removing of the child piece to/from the parent square), or using getChildAt(index:int) to try to access the child piece.
I want to go with the first route as it seems to be the most maintainable to me. My problem is that I can't work out how to manage empty squares in this scenario. My instinct is to null to private _piece property of one square once I've moved the child piece instance to another square... but I'm fairly certain that the private property is a reference type, and nulling it out will null the actual piece object even after it's changed parents.
My player movie clip has a smaller movieclip within it. Because the smaller movieclip is not within the parent clip it changes the x,y,width,and height value of the player movieclip and throwing everything off! To adjust I have to add (-2ndmovieclip.height) to everything i want to do. This is sloppy and I don't like it. Is there a better way to have a child within a movieclip without it affecting the parents properties? i want the parent to keep its original x,y,width,and height properties but the child keeps adding to them!
I am wondering how to correctly reference child/parent movie clips when creating event handlers? I have a button within a movie clip, which is within a movie clip.This is what my handler looks like right now:
The button instance name is ButtonSeats Problem is, I get this:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
Also, if I were to move the vent listener directly into the movie clip where the button is located, how could I reference the parent/ parent timeline(the main timeline)? Am I correct to understand that .this refers only to the current clip?
That class has a loop that creates / instantiates a number of copies of another movieclip from the library. This second movieclip has a textfield child in it. When I convert this textfield to a movieclip I can access the properties of it fine, but just as a dynamic textbox I can't access it.
This is the custom class of the second movieclip that gets instatiated a few times by the first custom class...
This custom class relates to a movieclip that has a child MC called recent_text (which I can access ok) and in that child is another child (a dynamic text field called "aDynamicTextBox", which I can't access)[code]...
I have container swf which includes navigation that loads child swfs. Each child swf is loaded then visibility is set to false. Once a child ( an image gallery actually) is loaded it is possible to jump from image to image. What Id would like to be able to do is call a "clean up" function that returns the child to its initial state when anothor nav link ( a different gallery) in the parent is clicked. But I do not know how the syntax is supposed to be written or if its even possible.
Ideally it would look something like this in the parent container swf:
ActionScript Code: function swapSectionIdentity(e:MouseEvent):void { setChildIndex(background_home, 0); getChildByName("identity_mc").visible = true;
[Code]...
the behavior I am attempting to avoid is when a child swf is loaded ( an image gallery) and then the child is invoked to display a particular image in it, afterwhich a main navigation link is clicked the current gallery is set to visible = false and a new gallery is set to visible = true. But when you return to the previous gallery the last image viewed is still showing. I want to be able to reutrn to galleries inital state as it is hidden. make sense?
I have setup a simple video interface. The video player lives in the parent swf. The video list chooser is loaded as a child swf. In this child swf, I have some video buttons nested within two movieclips in order to facilitate the scrolling feature. I am trying to get the movie buttons to load flvs into the component flv player in the parent swf. I have declared the functions in the parent and I am trying to call them in the child:Code in the Parent:
function vid1(event:MouseEvent): void{ pubPlayer.source = 'vid1.flv'; }
In my child constructor I use MovieClip(this.parent).blablabla() to retrieve info, yea I know I can pass it through the constructor, anyways I keep getting errors anytime I try to use MovieClip(this.parent) in the constructor, it gives a refrence error saying it's null.
Why doesn't that command work, is there a way around it (other than the constructor)? Is it because it's bad design? I'm calling a function that has alot of data, so I'm just passing this to the child and using the passed this data to call the parent atm, looking for a better MovieClip(this.parent) solution.
I am adding a child .swf from the parent with a simple button. If this button is then clicked multiple times, the child is added multiple times. So I added the ".visible = false" to the button when clicked so the button cannot be clicked while the child is open.
Now, there is "Close" button on the child .swf that uses "this.parent.parent.removeChild(this.parent);" and would now need to set the parent button back to ".visible = true".
I have tried MovieClip.parent.parent.resetButton(); and parent as MovieClip.resetButton(); and many variations of the code. I get no errors but the code doesn't work either.
I have uploaded a ZIP file that includes the following files:
- main.fla
- child.fla
You can download to review my code (very small 16kb): http:[url]...........This simple example has a main SWF file that loads a child SWF using the dynamic loader method. Below is the code in the main.fla file:
Code: Select all/* MAIN SW */ import flash.net.URLRequest;[code]........
how do I get both parent and child SWFs to communicate with each other dynamically (to be able to call functions from each other, or pass variables)?
I'm switching from as2 to as3 and everything was going swimmingly with my new site until i tried to use a _root call to a function on the main timeline by a loaded movieClip that is loaded nested into 2 other movieclips. the movieClip needs to tell the _root when it's done playing so the root knows to load the next one in line through a php call. Everything works except for the _root call. In as3 there's no such thing as root anymore so I figured no big deal, i'll just find out what the new thing is and holy crap wtf! I can't figure this out!! I've read from doing stuff like custom eventLisnters (which i am trying now) and casting the root as a movieClip and then I read this whole crazy tutorial on building an event structure and the proper MVC way of coding and blah blah blah ALL I WANT TO DO is tell the _root that the loaded MC has reached the end of its timeline. Basically if it were as2 i could just go _root.loadNext(); and it would work.how to make a loaded MC talk to the _root timeline and call a funciton from there?
I am a Flash MX user, I have three files named PARENT.SWF, CHILD.SWF, and CHILD2.SWF. The PARENT.swf loads the CHILD.SWF, The CHILD.SWF loads, then the file CHILD.SWF loads another swf file: CHILD2.SWF
Now my question is: How can the file CHILD.SWF unloads itself to avoid overlapping with CHILD2.SWF on the screen. I try the command: removeChild(CHILD); from CHILD.SWF but it doesn't. work.
If I need to call a specific function in the parent application from a child in a flex project, what's the best practice for this? Would it be to dispatch a custom event from the child and have a listener call that function? Or to directly call the function with FlexGlobals.topLevelApplication?
I got a Parent Sprite, let's name it SpriteP, which holds inside it two other Sprites. Sprite1 and Sprite2.[code]Sprite2 is a rectangle. When I rotate it, of course, the height of its parent, SpriteP, GROWS. But I would expect that height to go back to what it should be when I'm removing Sprite2!And it does! If I remove Sprite2 while NOT being rotated, the height of the parent drops back to normal, 200.
i am slightly confused about the parent and child relationship. lets assume we have several different instances, what would be difference of adding them all as children of the stage and creating a parent-child hierarchy between them(other than the access path).
I got a Parent Sprite, let's name it SpriteP, which holds inside it two other Sprites. Sprite1 and Sprite2.
When Sprite2 is NOT rotated:
Code: trace(SpriteP.width + ' ' + SpriteP.height); //100 250. SpriteP.removeChild(Sprite2) trace(SpriteP.width + ' ' + SpriteP.height); //100 200. -> works, 200 is good. When Sprite2 is rotated at 90:
[Code].....
And it does! If I remove Sprite2 while NOT being rotated, the height of the parent drops back to normal, 200. But if I rotate Sprite2, the Parent won't update its bounds.
Both files are running on the same domain.I am simply calling a another movie within a movie using the global variable feature.Howver even hardcoding the variable _global.directionsText the import-html.swf movie returns a undefined error
Code: //Frame 1 - Actionscript from Calling Movie _global.directionsText="http://www.mysite.com/access_db/viki...ive/myHTML.txt";[code].....
I have a label I am referencing form a movie clip inside the movie clip which contains the "label_2." Here is the code I used: MovieClip(parent.parent).gotoAndPlay("return_2"); Now I need to reference a instance name of a movie clip in side the same scene.
[code]All clips are squared.Ok, on the PlayerPlane, there are little soldiers, which have hotkeys. The effect I'm trying to create is I want to position the GameStage so that the currently selected soldier appears in the center of the GameClicker clip.The GameStage is movable by the player (to scan other areas of the map)by holding the CTRL key, so it's easy to kinda lose track of where your players are.I have tried using localTo Global and globalToLocal techniques, but I think I'm lost on the actual math of getting the GameStage to move the correct distance so that the selected soldier is centered to the GameClicker.[code]
I have an Movie Clip in Flash that have subobject of button type which has subobject of input text and movie clips. Right after creation core Moveclip all subobject are set to null, when I expect them to be valid objects.
[Code]...
MC_Core_design was created in Flash and exported to Actionscript. I've done this for button_1 class aswell. The code was written using Flex. When I comment out both lines that result in error I get correct view of the core Movie clip with all subobject. How can I set subobject properties right after object creation?
