ActionScript 3.0 :: Referencing A Loaded Clips Class?
Mar 18, 2009
I have a swf that is loaded into my main swf with the loader class. When I click a button in the main swf I want to call a function in the loaded swf Main class.
When I do a trace it is showing the loaded clip as [object Home] which is the name of the Main document class associated to the loaded swf. I have a public function in my Home.as called startAnimation() but when I try to call it I get
[quote]1061: 1061: Call to a possibly undefined method startAnimation through a reference with static type flash.display:Sprite.
I'm developing a Hygrometer in Flash CS4. The Hygrometer is a Movie Clip currently on the stage with 16 Movie Clips inside with instance names like segment01_mc, segment02_mc.. segment16_mc. I'm trying to make a class for the Hygrometer MC and I need to access the "segment" MC's. But I can't find a solution.
Is there any way to reference the "segment" movie clips? How can I assign instance names to the "segment" movie clips?
I've created a tsunami menu made up of duplicated menu items. Each menu item should have a rollover and selected state of 240% which works fine. When a menu item has been selected it jumps to another frame but until the user interacts with it it should loop through the different categories.My problem is that I can't get the menu items to scale big while it is looping through the different categories on the matching category frames.
i'm looping thru xml nodes and using this to attach clips to an empty mc:Code:item = _root.mainHolder.links.linkHolder.attachMovie("linkClip", "linkClip" + i, i);my question is how can I reference the previously attached clip so I can determine the _y property of the current item(clip).I'd like to do something like this.item._y= previously attached clip._y-previously attached clip.height
Ok, this is one of those walls that I know once I can jump over it, I will be a much happier developer again.
I've done tons of reading, and think I have a firm understanding that the general consensus is that if you want to reference something, it needs to be added to the display list, using addChild().
I hate to be defiant, but what if I don't want to?
Or at the very least, what if I want to add a movieclip class to the stage using addChild, and then reference objects inside it?
It is much easier this way than what most people recommend - adding 15 objects via addChild, then setting the x and y for the, etc.
That said, I'm all about using classes and using as3 the way it was meant to be used. So what this is, is a best practices question I guess.
HERE ARE THE STEPS I'M TRYING:
- Create new flash document
- Draw graphic symbol bg, with text field over it, select them, convert to movieclip symbol, and export class name "box", then delete it from stage
- Add document class .as file, which simply adds that class "box" from the library, to the display list using a simple addChild()
- Set a name for that box using box.name = "test" let's say
- Do a simple trace like the following - "getChildByName('test').textFieldName" - it shows up great
- So then, I'll now try to set the text by doing this - getChildByName('test').textFieldName.text = "yo";
That last line above, is what doesn't work. I know I'm referencing wrong, but how would a pro as3 developer, reference something on the stage within a movieclip class, from the document class?
I need to increment an integer variable in a function within the document class upon transpiring event in another class. I can't seem to figure out how to call the function and reference the variable.
I have an enemy on the stage that reads whether it's being hit by a bullet by a hittest. There's a for loop inside the enemy's class that looks for all the bullets and names the bullet that's hitting it "hitBullet". What I'd like to do have an easy way of seeing what type of bullet is hitting the enemy. I'm basically looking for something like
if (hitBullet == RegBullet) { //do regular bullet dying }else if (hitBullet == ClusterBullet) { //do clusterbullet dying }
, where RegBullet and ClusterBullet are classes. But I have no idea what hitBullet is equal to when a ClusterBullet or RegBullet hits it. I traced hitBullet to see what it would return and got "[object ClusterBullet]", but I'm not sure what that would be in the actual code.
I have created a loop to add my clips by class and give them a name
[Code]...
Then I want to loop through these clips and change the alpha, I have tried casting as I thought that was how you do it but I get the 'cannot convert string' error
I have a class called Circle and a class called ShapeFade, both with their own .as files. How do I add an instance of ShapeFade to Circle inside the Circle constructor? Like in the Circle file:
PHP Code:
public function Circle () { this.addChild (ShapeFade); }
Also, can I override a class function from the code window in the stage?
The following code gives me an error:1119: Access of possibly undefined property sp1 through a reference with static type flash.display:Sprite.Not sure how to get around this issue... these things used to work in as2, I guess not anymore in as3...
---------------------------------------------------------------------- ------------------------------------------------------- loader = new BulkLoader("timelineLoader");loader.add(ExternalFiles.TIMELINE_SWF);loader.addEventListener(BulkLoader.COMPLETE, onCompleteHandler);loader.start();
I just poked around google as well as these forums, but the only answer I am seeing that was successful, is from kglad, and for some reason his posts are not showingAnyway, I am just trying to figure how to reference a frame label on my main timeline from a loaded swf (through my imageLoader).
But when I do this, since the movie is not loaded the file is not compiled and gives me an error your referring to something that is not there. How else am I supposed to reference a content that will be loaded later?
The starting point is that I load an external PNG file into an open SWF application with the following code:
--------------------------------------- var loadListener:Object = new Object(); loadListener.onLoadInit = function():Void { //do certain actions - not relevant for my question };
[code]....
That works fine. The problem is how can I later reference to 'flower02.png' as BitmapData which is loaded as a movieClip into the movieClip 'mc1' to execute certain BitmapData methods like in particular 'copyPixels()'?I'm aware that I could use:
--------------------------------------- import flash.display.BitmapData; var libId:String = "flower"; var flowerBmp:BitmapData = BitmapData.loadBitmap(libId); ---------------------------------------
In this way I could reference my BitmapData by its variable identifier 'flowerBmp'. But this would require that my 'flower02.png' is already in the library which is not possible for my purpose.
I'm having trouble referencing variables in a loaded movie. I read in other posts that you simply refer to the variable as if it belongs to the clip you load it into, however this doesn't seem to be working for me
then MySWF doesn't show up on stage whereas with aSlider.addEventListener(SliderEvent.CHANGE,OnSliderChange); it does appear. I need to use this["aSlider"] because of this [URL] as pointed by [URL] to my previous question.
So I am using the following code to load an external swf and am trying to reference the timeline of the loaded movie i.e. a frame label. Say I wanted to do a simple gotoAndPlay what is the syntax? I would use (myloader.gotoAndPlay ("framelabel") this seems like an obvious answer but doesn't seem to work for me.
Code: Select allfunction yesClick(event:MouseEvent){ /////// Loader (Loads External SWF lesson file) ********************************** var myLoader1:Loader = new Loader();
I usually would call the parent of my class by something like: MyCustomClass1(parent).thisFunction(); My problem is this works if I know the class of my parent. How do you handle the case where you class could have a parent of 2 or more possibilities? parent.thisFunction(); // throws error of course
A have two classes: Main and Navigation. I try to referenceobject in Main class from Navigation class based on the buttonnumber I clicked. Doesn't work as I want it to work. What can I do
I have externalized the actionscript code of a movieclip into a separate class files.This movieclip requires references to some other clips on the stage. What I am currently doing to reference those clips is by using Movieclip(this.parent).otherclip but somehow that feels wrong.Is there a better way to pass in the required references into a class extending from Movieclip inside of the constructor? Or what is the recommended pattern here?
I have a bunch of variables in a class. There are situations when I want to set then to null/ "temp" etc as per a well defined logic. The challenge is to list out the variables at multiple places- tedious and error-prone.
would prefer a way to refer to these variables programatically and set something like "for all class variables- if variable ends in type, set as "not_set"; for other variables set as NaN How can I achieve this?
I can import other classes to the timeline and use them just fine, but this class is giving me major problems? I am parsing XML data from my server on it and it is giving me errors that look like this.
The timeline reference and usage: import networkScores; var network:networkScores = new networkScores(); addChild(network); score1Textfield.text = network.score1.toString(); [Code] .....
The errors I am getting: Scene 1, Layer 'Actions', Frame 4, Line 149 1119: Access of possibly undefined property score1 through a reference with static type networkScores. 1067: Implicit coercion of a value of type networkScores to an unrelated type flash.display:DisplayObject.
I'm working on a game that pulls most of its information from an SQL table. The game itself has several different items that derive from a BaseItem class, and all have widely varying behaviors. While deriving these classes from the BaseItem class and scripting the correct behavior is easy enough, I'm having a bit of trouble trying to come up with an efficient way of storing the information for these items so that not only will the items be in the state that the user left them when they were last saved to the database, but they will be the correct item when loaded from the database in the first place. I'd like to do this with as little pollution of the iteminfo table as possible (for instance, I want a Truck item to have a "wheels" value of 4, but I don't want an item_wheels field on the row if the item is Pogo-stick).
So far, my best idea has been giving iteminfo an "itemtype" field that accepts an enumeration, like ITEM_TRUCK or ITEM_POGOSTICK, and using a switch statement in AS3 to instantiate the correct item based on the pulled value, but this seems rather sloppy.
The thread title says that I want to reference a class directly from a table, but if I knew how to fix this I'd have done so already, so I'd love to hear any solutions. And just for the info: I'm working with a combination of AS3, PHP, and MySQL.
Is it possible to use a class name stored in a string and pass it as a parameter??I'm using the push method in a flex mobile project. I have the name of the view I would like to pass into the push method stored in a string. But the push method only accepts it as a class not a string.How do I use a String to load or pass the class name to the method?
var NameClass:Class = "views.Contact"; navigator.pushView(NameClass);
just thinking out the setup of a sidescroll/platformer..i want the player not to fall through the floor or go through walls i know how to hittest with a single object, but what i have is various objects that extend the class wall. if I hittest with wall will that also apply to the serrated_floor and portcullis classes that extend wall?
It's me again and I'm running into a problem. So, I have this movie clip that is nested inside multiple movie clips. I want to tell Flash to perform an action when that movie clip hits another movie clip in the main timeline. It's just collision detection for a game using the hitTestObject code. I was thinking of using MovieClip(root), but that won't work since it's nested so much.
I have a widget containing a number of displayobjects, i.e. up arrows, down arrows, tab 'buttons', backgroundrectangularblocks, sliders, company logos etc.I am currently creating these displayobjects using the graphics class with parameters taken from an external file, things such as fontsize, font, colour, width, height e.t.c and adding them as children of "container" sprite objects for easy manipulation and referencing later can these assets be loaded in their entirety externally, rather than being created using graphics class draw methods (which I want to avoid) as some of the things I need to design cannot be created in pure actionscript very easily (if at all?), and then used or do they always have to be in the library and instantiated from there?
if the first question is yes they can be loaded externally, this question probably isn't needed; however, if I have to put the items in the library and recompile each time a client wants to use say a curved blue up arrow instead of a yellow one and then decides he wants a yellow circle instead then how do I write the code to do the following:-Say on my first ever compile I have 'upArrowBtnset1' in the library, I instantiate it and use the instance name to access it in the usual way using standard code,
Now if they send me a second set of 'upArrow' graphics they want to use I could either update all the upArrowBtnset1 assets with the new graphics meaning the original set is no longer available to the client and I would either have to hold a "original set" FLA file with the first set of arrowbuttons or I could import these to the library as upArrowBtnset2 and a third set they send as upArrowBtnset3 and so on each time I am sent some new assets; I would then recompile them into the SWF and adjust the references to the new assets within the code. In the code, for each instance of "upArrowBtnset1" I would have to rename them to "upArrowBtnset2", recompile and send it back to the client.
Because I have already abstracted the font/colour/size choices out to an external file, they can change that as much as they like without a recompile which is what we want. The problem comes if they want to use set1 again and haven't kept the original "set 1" compiled SWF. It would be easier to abstract the 'setchoice' also to the external file. The SWF would over time build more and more available sets that they could use by just changing an external variable.
For example, if the designer wants to use set 1 on Monday, set 2 on Tuesday and set 3 on Wednesday I want to make it so they can just adjust an option in an external file to "setchoice = 3" for weds instead of either having to recompile the swf each time or they have to have 3 versions of the SWF for each asset set. The idea is that as more and more assets are added in, they have more and more choices. Ideally, in an external file there would be a list of assets and links to where they are loaded from. (i.e question 1 above).
If I have an external file (say XML) which holds the setchoice option that the designer wants to use (say they want set3 today) my 'generic' code has to be something like upArrowBtn(setchoice).scaleY and every instance in the code where that object is used I append the 'setchoice' as chosen by the designer from the external file where (setchoice) is retrieved from something like var setchoice:String = "set3"; from the external file (I am currently abstracting all the adjustable variables to a configuration.as file. I will work on using an XML later when the principle of external files works (I hope!);
Is it possible to import assets from external sources and then use them in the SWF as if they were in the library? The loader class? Is this just fraught with danger I wonder.
Essentially I am being asked to remove as much as I can from the SWF so that if the client wants to change the positioning of things on the stage or the text on buttons or change the style of the buttons or the company logo they don't have to come back to us to ask for a recompile of the SWF for each tiny adjustment. Inevitably SOMETIMES a recompile will be unavoidable (such as if they want the widget to suddenly be twice as wide (i.e. the stage). My code already handles some of this using stage.stageWidth and then positioning objects relative to other objects already on the stage using this value and centred so that just changing the document properties is all I would have to do and everything else adjusts proportionally. I am trying to make this as reusable as possible with as little effort from myself as possible to save our company wasted time.
After all that waffle, my question is this, if I can't load all my buttons and assets and things externally, how do I write the code for this:- I have a library asset called upArrowBtnset1 and another called upArrowBtnset2. Instantiated with say upArrowButtonset1 and upArrowButtonset2 The code would normally be upArrowButtonSet1.x = 100; upArrowButtonSet2.y = 300; but I need it to be upArrowButton(setchoice).x = 100; upArrowButtonSet2(setchoice).y = 300; where (setchoice) comes externally from var setchoice:String = "set1";How does the code change if the (setchoice) string was named not at the end i.e 'button(setchoice)UpArrow'?
ActionScript Code: var numClips:Number = 5; for (var i:Number = 0; i < numClips; i++)
[code]....
I need to do something like, getChildByName("mainTab"+i).addChild(myMovieClip) ? or maybe this["mainTab"+i].addChild(MovieClip)?Is it possible without using .name?
How to access stage elements from within a class. buttonControls.as
