ActionScript 3.0 :: Any Way To Check If TextField Is Object Present On Stage?
Dec 2, 2009
well both
if(xyz)
and
try{} catch (){} did not work. Both will cause compiler error "Access of undefined property xyz". Inept, what does getChildAt return? Does it return the textField object itself? If so, how do we test if its name is xyz?
I have created a listener for stage in a function. The same function is called by another function. Now I need to check with a condition that whether the stage listener is present or not.
three nav buttons which add movieclips to the stage using the addChild method bascially each new movieclip should remove the last one present on the stage. My code so far which is not working is the following:-
I'm just creating a movieclip from a text field object on the stage, giving it an instance name and setting some timeline animated over and out states for it. I'm then setting it up in AS3 to work like a button, so nothing complicated at all. But I am getting errors I have never seen before. Code is very simple basically I have a button called 'hair' contained within the mc 'menu', here it is:
Code: menu.hair.addEventListener(MouseEvent.MOUSE_OVER , itemOver); function itemOver(e:Event):void { trace(e.target); e.target.gotoAndPlay('over'); }
So I noticed there are some new text options in CS5, but none of them give the result I want. If I leave this as the (now default) TLF text, it gives a couple of errors related to this no longer being a movieclip;
Code: ReferenceError: Error #1069: Property gotoAndPlay not found on flash.text.engine.TextLine and there is no default value. at CL022_fla::MainTimeline/itemOver() [object SimpleButton] ReferenceError: Error #1069: Property gotoAndPlay not found on flash.display.SimpleButton and there is no default value. at CL022_fla::MainTimeline/itemOver() [object TextLine]
If I change it to classic, there are no errors, but the gotoAndPlay does not work. If I change the text to outlines, it works as per normal.
Why do I get this error saying parent does not exist when I try to remove a movieclip. In the first case, the movieclip cannot exist either on screen/memory if it was not 'contained' by either a movieclip or stage. How can this happen, can somebody explain how this "movieclip" loses its parent reference to the stage or container mc. The debugger stack shows the value of movieclip.parent as null.
There is a library component represented by Class A. But constructor of this class requires some parameters. When the component needs to be added dynamically, it's fine because of code :
var abc:A = new A(param1,param2)
But what if my movieclip is already present on the stage. I notice it gives out error, that the parameters are null.
Is their any way to insert constructor parameters for movieclips already on stage.
I have a strange issue where a dynamic text field will not show a bold version of a font (Gerstner BQ) if the regular version is on the stage in a static text field.Remove the static text field and the dynamic text field displays the bold font correctlyI have created a test FLA to reproduce this and by turning the layer with the static text field on and off (Publish settings -> Flash -> include hidden layers [unchecked]), the issue is quite clearhis issue is so big for me that I have had to abandon a project in CS5 and start again in CS4 just to work around this.
I was supposed to set the validate range for the Name field to be checked with an array of 3 names, the validate range for the Password field to be checked with an array of 3 passwords, and the validate range for the State field to be checked with an array of 3 states in order to create my own error messages.
stop(); var errors:Array=new Array(); function clearForm() { name_ti.text=""; state_ti.text=""; password_ti.text=""; [Code] .....
I have a movie clip that is added to the stage.. by the instance name of PHP Code:"ITEM1"Is there a way to check if a particular movieclip/instance is already on the stage?Maybe something along the lines of
I am trying to write an IF Else statement that will check to see if a movieclip on the stage has an external SWF loaded in it that was loaded using the loadMovie command. Does the loadMovie command or the internal movieclip object have any kind of a built in function that will return a value if it has an external SWF loaded in it?
I'm trying to create a slideshow, using Flash CS3 and AS3. I have 6 thumbnails with buttons attached to them, and then 6 movieclip images placed on the stage manually, each on a different layer. Inside of each image MC (i.e. image01_mc is the instance name of the first image), the image is animated to enlarge outwards from the thumbnail to make a larger version of the image. Standard operating procedures, and all that. So far, the buttons successfully call upon the frame label inside the imageClips to enlarge.
The next part of the problem is that when clicking the next thumbnailButton, I want the currently enlarged image to diminish in size back to its thumbnail, so that the next image can take its place. I have a frame label inside those imageClips to make that animation.
I think, with my rudimentary understanding of AS3, that I need to find out which movie clip instance is on the stage, using If statements, with some code to gotoAndPlay the frame inside the imageClips that shrinks the image.
I've tried various combinations of If, Else if, getChildByName, etc, that I've found in numerous posts, but nothing seems to work.
Not sure the best way to do this. I have a class we will call DropActivity, here is the code
[Code]...
when the stopDraggingMe() method is called from another object (code shown below) I need to see all the objects on the stage to see what objects on the stage my currently selected movie clip is over and assign it to the dropCheck.checkAgainst method (that will be checked against an array to see if it can in fact be dropped, if so set the canBeDropped value to true and therefor run the .stopDrag() ). I have read using root is not a good coding practice in AS 3.
Is it possible to check, using Javascript and without altering the ActionScript code at all, if a child has been added to the stage? I have in mind something like being able to call GetChildByName in Javascript, and if the child exists, call another javascript function.
i am trying to check if the movieclip has left the stage. by using the Stage.width. When the movieclip leves the stage no it not recognised. As the trace function does not appear.
var stageName = Stage.width; var speed:Number = 5; box.onEnterFrame = function(){
I don't work with the Flash IDE very much, and I'm running into a problem with the unreliable creation order of components instantiated by the Flash IDE "magic".
Basically, I have to call a function on a loaded module. This function should only be called after all the module's children have been added to the stage.[code]...
I have a lot of different movieclips on the main stage, with a majority of them being mcHotspot movieclips. These mcHotspots are simply yellow boxes which display a 40% alpha so users can see where they can click on the stage. When you click one of these hotspots, a menu is displayed which contains more mcHotspot movieclips embedded within it.
I'd like to have a single button that will loop through all the items on the stage and display anything that is of type "mcHotspot". Is this possible, and is there a way I can dig down into any items of type movieclip that are NOT mcHotspots to see if they have mcHotspots themselves? I'm basically looking to use a recursive loop that will go to the lowest level. I know there is a typeof function that returns either Number, String, movieclip, etc. but is it possible to know what type of movieclip it is?
I'm loading external swf and I want to check it's stage width and height, do you know how to do this? I dont want to check the width and height of the swf because it changes depending on which frame is currently playing in this swf...
I would like to know how to perform a check on the direction of the movement of the mouse on stage like let us say considering the stage.height/2 as the center if the mouse moves up it should trace up and down if it moves down... I did it by storing all the _ymouse coordinates in temp array and chking if temp[i]>temp[i-1] but it doesn't work satisfactorily. i am posting the script i made...i do admit i am very bad in calculations so correct me if i went wrong somewhere
I have a movieclip AAA(W:550xH:1200) placed on the stage (W:550xH:400). Inside of the movieclip, there are many other moveclips. I like to implement this result: When I scroll(Y-axis) the movieclip AAA to a position, the moveclips inside of AAA will fade in, and the other movieclips out side of the stage will fade out.
I want to check in my function if a passed argument of type object is empty or not. Sometimes it is empty but still not null thus I can not rely on null condition. Is there some property like 'length'/'size' for flex objects which I can use here.
