ActionScript 3.0 :: Any Way To Get TextField Recognized Without Instance Name
Jun 14, 2009
I'm trying to have action script recognize a text field without me having to give it an instance name. All is fine at first because i wrote custom errors to show if Flash doesnt find a text field on the stage, and no errors come up. I know that my errors work because when I remove the text field from the stage all the errors appear. The problem arises when I try to manipulate the text field through AS that I right on the main timeline. When I do then I get that old 1119 undefined property error.
Here's my code.
package com.nate.ui {
import flash.display.Sprite;
import flash.events.Event;
import flash.net.*;
import flash.text.TextField;
public class TextArea extends Sprite {
[Code] .....
And here is just my trace (on the timeline) that throws up the 1119 error.
trace(ta.textField);
I bought Flash recently and I'm getting started on making a game, a platform shooter game, thing. What I have, is a button on the main stage that I want to activate a function in an instance. But that instance is inside a symbol. So it's Stage->Character->Gun. But if I put down:
Shoot.addEventListener(MouseEvent.MOUSE_DOWN, Fire); //Shoot is the button on the stage function Fire(evt:MouseEvent):void{ Derp(); //This being the function I want to be activated }
This is the code in the Gun instance: function Derp():void{ //epic code goes here }
It will give me an error saying "1180: Call to a possibly undefined method Derp." So basically it's telling me it can't get to this code because it's not on the same stage. How can I get an instance to be recognized by all code in my project, regardless of we're it is in the project? I want to keep all my symbols where they are, so external ActionScript file won't be good if I have to recreate the object on the stage.
I have created some text fields by loading a file and reading the info and placing each one into its own text field. How do I access each text field now? I want to perform a certain task on each one, but I don't know how to. Is there any way I can give it an instance name when I create it?
I have a movie clip which animates out and then places an input textfield on the last frame for the user to type in to. The main movie clip is controlled from external ActionScript. Once the last frame hits and the input field shows I want to focus the users cursor with focus(); but I can't figure out how to call to that TextInput from the time line. mytext.focus(); ???
I'd like to know if there is a way to reference a dynamic text box's instance name through the use of a string.I know that this["the string"] works for movieclips, but haven't had much luck with the text field.Here's a simplified snippet of code I have so far - The goal is to replace txtInstance with txtInstanceArray[k]
var txtInstanceArray:Array = ["txtInstance","txtInstance1","etc"]; var colArray:Array = ["hitsum","hitsum1","etc"]; for (var k:int = 0; k < 30; k++){
So basically i have a bunch of movie clips which have instance names that i am pushing to an array and then that array is printed to a dynamic text field that displays the list of the movie clips. The issue is, i want this list to look presentable and since instance names cant take spaces only underscores then it looks so un-presentable
ActionScript Code: import flash.text.TextField; //Array to hold the target instances, the drop instances,
I am having a bit of a headache with regards to this problem
Code:
class A { private var tf:TextField; private var canvas:MovieClip
[code]....
Why is it that the above code does not work? I need reference to the textfield so i can apply different TextFormats depending on the state of target_mc.Why does flash complain that Void is found where textField is expected?
Is it possible to add a textField dynamically but have different instance name each time this is created? In other words if I have a button that whenever its click it will add a textField to the stage and assigns a new instance each time this is added.
ActionScript Code: button.addEventListener(MouseEvent.CLICK, addField); var inputWidth = 200; var inputHeight = 20; function addField(event:MouseEvent):void{ [Code] .....
Something like this but instead of textFieldName this would be different each time.
What I'm trying to do is create a simple message class that I can pass a set of textfield parameters of my choosing rather than specifying each textfield parameter in the constructor.Is it possible to pass a textfield instance an object of parameters instead of setting each one individually?
Code: public class Example { private var message:String; private var messageTextField:TextField;
I created a button (button symbol), inside this button symbol there is a vector shape which will change colours in mouse over and a dynamic text field. i want to use this button symbol in more than one locations in my stage. so i need to change the label of these instances (by changing dynamic text ). but i can't access the dynamic text in as3 using following code,
btnsample.txtbtnlabel.text = "button label"
this code is working fine for a movie clip symbol but not for a button symbol.
I trying to create a TextField in a Actionscript file, But when I try to create an instance of the class in flash no textfield is appearing. [code]...........
I'm making a project that is based almost entirely on code and I'm using classes. And everything was working fine until I came to a situation where I needed to make text field inside flash and not with code. I made a text field put some text inside, converted to a MovieClip, set the "export for actionscript" linkage in the library and deleted the movieClip from the stage.
Then went to my document class and wrote this code:
ActionScript Code: var txt:text1 = new text1(); addChild(txt); txt.x = 20; txt.y = 20;
And I get this error: Error #1009: Cannot access a property or method of a null object reference.
Weird. I don't understand this problem. I then put this as3 code into the first frame and disabled the document class. And the text appeared normally on the stage.
What is even more weird. I get the same error even if I delete this code. In other words, I get this error just by having this text object inside my library.
So what do I do wrong? Why can't I use this command in my class? And what is happening this just by having this object inside my library?
Is there a way to assign an 'Instance Name' to a dynamic Textfield' using the flashplayer5 export settings? Export gives me this error message : WARNING: This movie uses features that are not supported in the Flash 5 player Symbol=uitelgMc, layer=Layer 2, frame=1:Flash MX Text Field Instance Name Is there a workaround since I have to keep the movie fp5 compatible and I want to use the XML object to load text into the textfileds.
I've created an button object in flash. The button contains 2 layers. One is the background image and on top of it is a textField. The textfield is dynamic. I use the button inside a movieclip and I export it in a SWC. The I'm trying to use it in flex.
I'm trying to do this:
var myComponent:MyComponent = new MyComponent(); myComponent.button01.theTextField.text = "Caption";
I get and instance of the button(myComponent.button01 is not null in Flex debugger), but the instance of the textField(myComponent.button01.theTextField) is null and I'm not able to change the text(but the default text appears onscreen). The code is compiled correctly in flex.
I exported the in swc the button control as well. So the button is not the default SimpleButton from Flash, but an derived class generated by flash(with the same name as the symbol defined in flash). It contains theTextField memeber, which is null.
Here is the button timeline(Layer 2 contains the textfield, and the textfield instance is named theTextField):
Does creating a new instance of an Object that uses an identical name to an older instance, delete the previous instance? Or should the original instance be deleted first? The code uses a ridiculous amount of XML vars. Isn't it less memory intensive to parse the XML and save the properties to an Object, and then delete the XML Object, rather than keep the XML Object around and reference it's child nodes directly? Is it better form to break up a huge XML file (>600lines/3200vars) into smaller chunks?
I had this posted in another post I had which was answered and it also had a lame post name so I have reposted it here I can not figure out why my code here is not working.... (i guess that's pretty obvious or I would not be posting it!).
Would you mind taking a look at this and possible you can spot what it is that I have wrong?
I am getting the error:TypeError: Error #2007: Perameter url must be non-null. at flash.display::Loader/_load() at flash.display::Loader/load() at asFiles.reality::RealityScenarios/loadImage()[C:(networkpath).as:226]
is System.gc() recognized in AIR 3 for iOS ? Or am I putting on a line a code that's just for pasterity ? I have made every effort to dispose(),null and removeEventListener any unused Object, hence to be able to tell the Garbbage Collector to "go ahead" is a really awesome feature.
In Flash CS4, I've got a project that's working with a lot of XML. Previously, it's all been working fine, but recently I'm getting warnings like this when trying to compile:
Warning: 3594: toXMLString is not a recognized method of the dynamic class XML.
Warning: 3594: appendChild is not a recognized method of the dynamic class XML.
The lines of code that these errors refer to are:
stream.writeUTFBytes(currentXML.toXMLString());
and
currentXML.appendChild(marker.getXML());
"stream" is a FileStream object and "currentXML" is an XML object. "marker" is an instance of my own class, which I have imported, but I'm pretty sure that's not related.As I've said it's only happening now. I don't see anything in my code that could have changed it. Even if I turn the changes into comments, I still get errors.In addition to these two I am also getting other warnings, although all of them concern a method "not being recognized" in the XML class.I am using Flash Pro CS4 and am coding on the first frame of the timeline, as opposed to in a Document Class. Oh, and I'm making an AIR app, not a Flash Player one.
I'm using Flash CS4, and using ANY method for capturing keypresses, only some keypresses are recognized. Backspace, Enter, and all of the letters on the keyboard do not trigger anything for me. Even using code as simple as...
I have a movie clip on stage; instance name: "slide_mc" on the enterFrame of slide_mc, I fill slide_mc by using: this.attachMovie (_global.myNewCip,"newMC",1); // _global.myNewCip holds the linkage identifierThroughout my swf, I use attachMovie to swap out new movie clips in slide_mc like this:this.slide_mc.unloadMovie (); //clear contents of slide_mc slide_mc.attachMovie (_global.myNewCip,"newMC",1);There is a button on the movie clip I just attached to slide_mc. Its instance name is: "pause_btn"From the main timeline I try to detect a mouse click by using this
I wanted to use Cs4 to edit a flash template but noticed it kept saying I did not have tahoma font installed. I checked the font folder and I did have the font installed on the system but nevertheless I reinstalled it which did not fix the problem so I manually mapped/substituted it to the Tahoma I had on my system but noticed the fonts still appeared off when I published. I have uninstalled and reinstalled the software and it still occurs.
Why isn't the "finco" not recognised/passed to php? I'm not getting the text results!! Code: var finco = "motors01"; XMLParser.load("[URL]"+finco, onFinish); function onFinish($success:Boolean, $results:Object, $xml:XML):Void { if ($success) { category.text += $results.category[0].value; namez.text += $results.namez[0].value; [Code] ......
I'm writing an application which uses cookie-based sessions for authentication. All was well until I tried to integrate the uploadify jQuery plugin into my site. I need uploadify to send the files to my upload.php file. When I check the existence of any preknown session variables in that upload.php script, I get nothing. I've tried print_r($_SESSION) and got an empty array.
I'm not sure if this a problem with my php sessions code or my jquery uploadify code. I'm somewhat new at both.
I'm trying to make a game like Mario. I've made a character which can jump right now, but I've got some problems with collision detection.
I would like my character to jump on a bar, which is placed higher. My collision detection doesn't work at all I gues..I've made a cirle which has a instance name mcMain and I've made a MovieClip of it. T also made a rectangle which has a instance name balkje, I also made aMovieClip of it.
I hope you can tell me what is wrong about my code and what I've to change to make the collision detection work!
I have 2 movieclips on stage; one called 'myMarker_mc', the other called 'myMarker_mcOne') - they both contain 4 children (bt_up, bt_dn, bt_remove ) and myText (a textfield) and they only work properly when it is the 'myMarker_mc' that is being called (called from the xml at the top of the file).
When myMarker_mcOne is called the dynamic textfield, called 'myText' produces a blank and the output box pops up with...
